Quando comecei a codificar em JavaScript em 2013, pensei que jQuery era o “JavaScript” real e que jQuery deveria ser incluído em todas as páginas para executar meu código JS. Caros desenvolvedores de plug-ins Mas por que? Porque todo código que copiei do StackOverflow funcionou somente após importar o jQuery! 😅 O que há de errado com jQuery jQuery tem 90 KB, mas quando reduzido tem apenas 32 KB. Isso é tão pequeno. Um bom CDN pode entregar isso em menos de 50ms! Mas não se trata do tamanho. jQuery tem cerca de 10 mil linhas de código. Você pode não estar usando nem 10% dele. Cada linha deve ser analisada e avaliada pelo navegador, o que consome muitos recursos. Este processo afeta o tempo de renderização, especialmente em dispositivos móveis. Para ver a diferença real, aqui está a mesma funcionalidade escrita em jQuery puro e JavaScript vanilla: jQuery: // jQuery const div = $("#hello-div"); for (let i = 0; i < 10000; i += 1) div.append(" Hello world "); JavaScript baunilha: // Pure JavaScript const div = document.getElementById("hello-div"); for (let i = 0; i < 10000; i += 1) const p = document.createElement("p"); p.textContent = "Hello world"; div.appendChild(p); Aqui está a diferença de desempenho: Enquanto jQuery levou 2,4s, JavaScript puro levou apenas 0,8s. Isso mostra Vanilla JavaScript é 4x mais rápido que jQuery. Alguns anos atrás, escrever funções padrão em JavaScript vanilla era uma dor e o jQuery tornou nossas vidas mais fáceis. Mas os navegadores da web evoluíram muito. A maioria das funções que você escreveu em jQuery podem ser escritas em JavaScript puro. Aqui estão alguns exemplos: 1. Solicitações Ajax Buscando dados de um URL: jQuery: $.ajax( url: '/api.json', type: 'GET' success: (data) => console.log(data) ) JavaScript baunilha: fetch('/api.json') .then(response => response.text()) .then(body => console.log(body)) 2. Encontre elementos e manipule Encontre alguns elementos do DOM (HTML) e mude de cor: jQuery: Olácomo vai você? Meu? Eu sou bom. $("p").find("span").css("color", "red"); JavaScript baunilha: Olácomo vai você? Meu? Eu sou bom. document .querySelectorAll("p > span") .forEach((elem) => (elem.style.color = "red")); 3. Mostrar/ocultar elementos Caso de uso comum de jQuery, mostrar/ocultar algo ao clicar: jQuery: Me esconda $("#button").click(function () $("#button").hide(); ); JavaScript baunilha: Me esconda document.getElementById("button").addEventListener("click", function () document.getElementById("button").style.display = "none"; ); 4. Animar jQuery: Me esconda $("#button").click(function () $("#button").hide("slow"); ); JavaScript baunilha: .animate opacidade: 0; transição: opacidade 0,5s de facilidade; Me esconda document.getElementById("button").addEventListener("click", function () document.getElementById("button").classList.add("animate"); ); Você pode encontrar muito mais exemplos semelhantes em: Você pode não precisar do jQuery Você deve usar ou aprender jQuery em 2020? Do jQuery ao JavaScript – Como fazer a mudança E quanto ao suporte ao navegador? A maioria das funções que usei acima são amplamente suportadas em todos os principais navegadores. Caros desenvolvedores de plug-insCaros desenvolvedores de plug-ins Geralmente é o Internet Explorer e o Opera Mini, que não suportam alguns deles. Se ainda quiser oferecer suporte a esses navegadores antigos, você pode detectar o navegador e adicionar polyfills. Aqui estão alguns polyfills para essas funções comuns: github/eventlistener-polyfill github/buscar iamdustan/smoothscroll yola/classlist-polyfill Suporte do navegador para querySelector: Suporte do navegador para fetch: Todo mundo está se mudando, exceto WordPress Graças ao avanço feito nas ferramentas de desenvolvimento front-end e no suporte do navegador,

agora podemos descartar o jQuery como uma dependência, mas você nunca notaria o contrário Caros desenvolvedores de plug-ins Bootstrap 5 – postagem no blog GitHub.com também removeu o jQuery em 2018 – Removendo jQuery do front-end do GitHub.com. Embora todos tenham começado a se afastar do jQuery, é bastante complicado no WordPress devido ao grande número de plug-ins e temas. Da recente postagem no blog de Atualizando a versão do jQuery fornecida com o WordPress: O WordPress deve descontinuar o jQuery e migrar gradualmente para o Vanilla JavaScript. Talvez você também não precise de JavaScript Caros desenvolvedores de plug-ins Como eu disse antes, a web e o JavaScript estão evoluindo rapidamente. Da mesma forma CSS. Muitas funções que eram feitas via JavaScript agora são feitas via CSS. Isso proporciona outro aumento de desempenho. Caros desenvolvedores de plug-ins Algumas delas que podem ser feitas em CSS puro: Controle deslizante de imagem – Construtor de controle deslizante CSS, Galeria CSS, Controle deslizante CSS puro Modal – Modal CSS Puro Validação de formulário – Validação de formulário HTML Indicador de rolagem – Indicador de rolagem somente CSS Acordeão – 4 maneiras de criar acordeões incríveis somente com CSS Caixa de luz – Caixa de luz CSS pura, Caixa de luz somente CSS Guias – Guias somente CSS, Guias somente CSS do Material Design Role para cima - Puro CSS Smooth-Scroll “Voltar ao topo” Rolagem suave para links – Demonstração de rolagem suave CSS Barra de navegação fixa – Cabeçalho fixo CSS puro Caros desenvolvedores de plug-ins

[JS] Table 轉 Object 練習 part1

自從工作開始分前後端分離之後，JavaScript 的東西就比較少去鑽研，但近期又開始大量的用到 JS 的東西，有些東西就需要重複的使用，JS 的陣列變化，從以前學會的 jQuery each ，演變到可以直接 querySelectorAll 之後跑個 forEach 真的很方便，大大減少了對 jQuery 的依賴程度，反而開始探究起 JS 的原生有哪些 function 可以玩這個時候 MDN 就是個很好用的工具寫程式不需要一步到位，逐步漸進的達成目的，有機會再去把程式碼精簡調校，能夠理解其原理才會是最好的解法這次就簡單的寫個當遇到表格，要怎麼轉成一般的 Plain Object ，這個也是我用 Greasemonkey 要爬 dom 的時候，很常用到的用法，就是把 DOM 轉換成資料傳遞首先來一個範例 Continue reading Untitled

How to show x-left in configurable product in Magento2

In a modern world, an e-commerce platform Magento is well known for its flexibility and open-source ecosystem. It is powerful enough to handle all type of businesses ranging from small cap to large enterprises. To run a successful ecommerce store it requires great efforts to be done by the store owner to maintain products and all. Many products sold online comes in different size, color, length. While displaying these products on the front end, it is important to make the options clear as well as variations in quantity left in stock.

Recently our developer has made an extension on how to show x-left in a configurable product in Magento 2. The script shows the number of variant according to specific length and size. Actually, that script is pretty useful for everyone so we decided to share the script on our blog.

The particular product is selected.

Load the stock_threshold_qty and product qty

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$StockState = $objectManager->get('\Magento\CatalogInventory\Api\StockStateInterface');

$qtyPro = $StockState->getStockQty($_product->getId(), $_product->getStore()->getWebsiteId());

$conf = $objectManager->get('Magento\Framework\App\Config\ScopeConfigInterface')->getValue('cataloginventory/options/stock_threshold_qty', \Magento\Store\Model\ScopeInterface::SCOPE_STORE);

Specific size and length of a configurable product is selected

get current product

$product = $objectManager->get('Magento\Framework\Registry')->registry('current_product');

$mTo = $product->getResource()->getAttribute('mto')->getFrontend()->getValue($product);

//get current product

$productTypeInstance = $product->getTypeInstance();

$configId = $product->getTypeId();

//Main configurable product ID

//echo $product->getName(); //Main Configurable Name

Check if product type is configurable and has option:-

<?php if ($configId == 'configurable') { ?>

<?php

$usedProducts = $productTypeInstance->getUsedProducts($product);

foreach ($usedProducts as $child) {

$sId = $child->getSize(); //Child Product Sku

$skU = $child->getSku(); //Child Product Sku

$sId_Length = $child->getLength(); //Child Product Sku

$qtyProd = $StockState->getStockQty($child->getId(), $child->getStore()->getWebsiteId());

$siZe = $child->getResource()->getAttribute('size')->getFrontend()->getValue($child);

if($siZe)

{

//echo "size h";

//echo "<br>";

}

$lenGth = $child->getResource()->getAttribute('length')->getFrontend()->getValue($child);

if($lenGth !="No")

{

//echo "length h";

//echo "<br>";

}

<?php if ($qtyProd < $conf && $qtyProd > 0) { ?>

<div style="margin-top:-21px;" id="remaining_<?php echo $sId; ?>_<?php echo $sId_Length;?>" style="visibility:hidden;" class="availability only" title="Only <?php echo $qtyPro; ?> left">

Only <span style="line-height: 20px;" class="counter-label"><?php echo $qtyProd; ?></span> left in <?php echo $skU; ?>

</div>

<?php //echo "<br>"; ?>

<?php } } } ?>

Place the small js script end of the file –

require(['jquery'],

function($) {

setTimeout(function(){

var pri_id = 0;

$(".length .swatch-option").on("click", function(){

var se = $('.swatch-attribute.size').attr('option-selected');

if(se>0){

var r = $(this).attr('option-id');

$('#remaining_'+se+'_'+r).css("visibility","visible");

var hidden_text = $('#remaining_id').val();

$('#'+hidden_text).css("visibility","hidden");

$('#remaining_id').val('remaining_'+se+'_'+r);

}

});

$(".size .swatch-option").on("click", function(){

var se = $('.swatch-attribute.length').attr('option-selected');

if(se===undefined){

var r = $(this).attr('option-id');

$('#remaining_'+r+'_').css("visibility","visible");

var hidden_text = $('#remaining_id').val();

$('#'+hidden_text).css("visibility","hidden");

$('#remaining_id').val('remaining_'+r+'_');

}else{

var r = $(this).attr('option-id');

$('#remaining_'+r+'_'+se).css("visibility","visible");

var hidden_text = $('#remaining_id').val();

$('#'+hidden_text).css("visibility","hidden");

$('#remaining_id').val('remaining_'+r+'_'+se);

}

});

}, 2000);

});

</script>

Specific product of selected size and length has been added to the cart.

A nice list of HTML, CSS and JavaScript How Tos with basic concepts for everyday use. Feel free to comment your own approaches :)

Disabling everything with CSS

CSS

.disabled { filter: grayscale(1); pointer-events: none; }

View on JSFiddle here.

Split an array into chunks without mutability

const array = [1, 2, 3, 4] const size = 3 const new_array = array.reduce((acc, a, i) => { i % size ? acc[parseInt(i / size)].push(a) : acc.push([a]) return acc }, [])

or even shorter:

const new_array = array.reduce((acc, a, i) => i % size ? acc : [...acc, array.slice(i, i + size)], [])

Remember, start using const, if you need to change its value then use let and avoid as much as possible var. View on JSFiddle here.

Saving and loading dates

Save your datetime always in UTC ISO and load it to the user interface using local ISO. Use native widgets to avoid facing date format preferences (middle endian, little endian, etc) HTML

$button_save.onclick = () => localStorage.setItem('datetime', $input.value && new Date($input.value).toISOString()) $button_load.onclick = () => $input.value = localStorage.getItem('datetime') && toLocalISOString(new Date(localStorage.getItem('datetime'))) .slice(0, -8) function toLocalISOString(d) { const offset = d.getTimezoneOffset() return new Date( d.getFullYear(), d.getMonth(), d.getDate(), d.getHours(), d.getMinutes() - offset, d.getSeconds(), d.getMilliseconds()).toISOString() }

View on JSFiddle here. I recommend using sessionStorage and localStorage. Do not abuse cookies if they are not strictly necessary. If you need more local storage you can use IndexedDB.

Select HTML table columns by clicking on the headers

document.querySelectorAll('th').forEach($th => $th.onclick = event => { document.querySelectorAll(`td:nth-of-type(${event.currentTarget .cellIndex + 1})`) .forEach($td => $td.classList.toggle('selected')) })

Remember, onclick always overwrites the previous function (in case there was any), use addEventListener() for multiple functions. View on JSFiddle here.

Rename when destructuring

We are going to rename time property while sorting our array of objects. JS

let times = [ {name:'dog', time: '10:23'}, {name: 'laundry', time: '09:34'}, {name: 'work', time: '11:00'}] times.sort(({ time: a }, { time: b }) => a < b ? -1 : a > b ? 1 : 0)

Remember, sort() changes the orginal array. View on JSFiddle here.

Autocomplete dropdown

Have you ever used autocomplete dropdowns from jQuery UI or Bootstrap third party options? A complete heavyweight mess. Luckly, we got a couple of years ago an awaited solution: Native HTML5 Autocomplete dropdown with datalist. A lightweight standard supported in all devices. HTML

View on JSFiddle here. Save your tooling time and dependency, use as few libraries and frameworks as possible!

Real easy responsiveness with CSS Grid

CSS Grid is the easiest, cleanest and powerful way to deal with responsiveness, a completely new approach baked in the last years and ready to use. CSS Grid changes how you used to layout your documents, instead of divitis (plenty of divs) and JavaScript to change div positions depending on screens (what Bootstrap does nowadays), you can use pure CSS grid layouts with just the meaningful divs and independently of document source order. You don’t need to touch HTML or JavaScript, you don’t need Bootstrap or even complex CSS rules, what you see in your CSS is what you get on your screen. HTML

<div class="grid"> <div class="name">Name</div> <div class="score">Score</div> <div class="skills">Skills</div> <div class="chart">Chart</div> </div>

CSS

.grid { display: grid; grid-template-areas: "name" "score" "skills" "chart"; } @media only screen and (min-width: 500px) { .grid { grid-template-areas: "name skills" "score skills" "chart chart"; } } .name { grid-area: name; } .score { grid-area: score; } .skills { grid-area: skills; } .chart { grid-area: chart; }

View on JSFiddle here. I would recommend you to do these examples. Fall in love with Grid Templates like I did ❤

Move parts of the user interface without loss of interaction

HTML

<ul> <li> <button id="up">Up</button> <button id="down">Down</button> </li> <li>Nothing</li> <li>Nothing</li> </ul>

document.querySelector('#up').onclick = e => { const $li = e.target.parentElement if ($li.previousElementSibling) $li.parentElement.insertBefore($li, $li.previousElementSibling) } document.querySelector('#down').onclick = e => { const $li = e.target.parentElement if ($li.nextElementSibling) $li.parentElement.insertBefore($li.nextElementSibling, $li) }

Remember, target is what triggers the event and currentTarget is what you assigned your listener to. View on JSFiddle here.

HTML input time with 24 hours format

Rely on native HTML widgets without depending on third party libraries. However, sometimes there are some limitations, if you have ever dealt with an HTML input time you know what it is about, try to set up maximum or minimum hours/minutes and/or change from 12 hours format to 24 hours and viceversa. By now, a good solution to avoid headaches is to use 2 inputs of the type number and a pinch of JS. HTML

CSS

div { background-color: white; display: inline-flex; border: 1px solid #ccc; color: #555; } input { border: none; color: #555; text-align: center; width: 60px; }

document.querySelectorAll('input[type=number]') .forEach(e => e.oninput = () => { if (e.value.length >= 2) e.value = e.value.slice(0, 2) if (e.value.length == 1) e.value = '0' + e.value if (!e.value) e.value = '00' })

Remember, == double comparation for equality and === triple one for equality and type. If you want to check whether a variable is undefined or not, simple use triple compartion a === undefined and the same for null. If you want to check whether it exists or not use typeof a != 'undefined'. View on JSFiddle here.

Loop n times without mutable variables

[...Array(10).keys()] .reduce((sum, e) => sum + `<li>${e}</li>`, '')

also like this:

[...Array(10)] .reduce((sum, _, i) => sum + `<li>${i}</li>`, '')

View on JSFiddle here.

Horizontal and vertical center

Forget about any complicated way, just use Flexbox and set up horizontal center and vertical center in the container. CSS

body { position: absolute; top: 0; right: 0; bottom: 0; left: 0; display: flex; justify-content: center; align-items: center; } div { background-color: #555; width: 100px; height: 100px; }

View on JSFiddle here.

Asynchronous fetch

Using fetch() with asyncronous functions. JS

async function async_fetch(url) { let response = await fetch(url) return await response.json() } async_fetch(‘https://httpbin.org/ip') .then(data => console.log(data)) .catch(error => console.log('Fetch error: ' + error))

View on JSFiddle here. Note, as you have noticed I don’t write the ; semicolon, that’s perfectly fine, in JavaScript the ; is not mandatory, it doesn’t matter if you write it or not, the JS engine is going to check it and insert it if needed, just be careful with new lines that start with ( parentesis and avoid return with the value in a diferent line.

Footer with right and left buttons

HTML

<footer> <div> <button>Button A</button> <button>Button B</Button> </div> <div> <button>Button C</button> <button>Button D</button> </div> </footer>

CSS

footer { display: flex; justify-content: space-between; position: fixed; bottom: 0; left: 0; right: 0; }

View on JSFiddle here.

Scroll into view

I have created n boxes (divs) with random colors to select one of them randomly and make it visible on the viewport. Every time you rerun the code you will see in your screen the selected box regardless of its position. JS

document.querySelector(`div:nth-child(${random})`).scrollIntoView()

View on JSFiddle here.

Flattening arrays of objects

array = alphas.map(a => a.gammas.map(g => g.betas) ).join()

If you want to see other different approaches using forEach with concat and with push check this link (I did also some time consuming test using jsPerf). View on JSFiddle here. Remember, in case you want to flat arrays of arrays you can do it easily with flat().

[1, 2, [3, 4, [5, 6]]].flat(Infinity)

Nesting arrays of objects

Returns an array of n elements filled with content: JS

let get_array = (n, content) => Array(n).fill(content)

Returns an object with a name property that has a content value:

let get_object = (name, content) => Object.defineProperty({}, name, {value: content})

3 levels of arrays with objects (nested)

a = get_array(3, get_object('b', get_array(6, get_object('c', get_array(3, {}) )) ))

View on JSFiddle here.

Array without duplicate values

const array = [1, 2, 3, 3, 3, 2, 1]

The Set strategy:

[...new Set(array)]

The filter strategy (easier to figure out but slower):

array.filter((elem, index) => index == array.indexOf(elem))

View on JSFiddle here. Remember, Array.from(iterableObj) = [...iterableObj]

HTML input with units

HTML

CSS

span { background: white; border: 1px solid #e8e8e8; } input { background: inherit; outline: none; border: none; padding: 0 5px; }

View on JSFiddle here.

Responsive background loop video

HTML

CSS

video.landscape { width: 100vw; height: auto; } video { width: auto; height: 100vh; }

Remember, you can add as many sources as you want to support different video formats. View on JSFiddle here.

How to print specific HTML content

If you want to print a specific HTML content, for example everything inside a div tag or a tag element with a particular identifier, you can use window.print() in a new window with just the content you want to. It’s easy but tricky, we would like an accessible print method for any HTML element but there aren’t. Don’t forget to add/link some CSS in your new window otherwise you will get the default style from your browser. JS, HTML, CSS

function print(content) { let win = window.open() win.document.write(` <html><head> <title>Report</title> <style> div { display: inline-flex; width: 200px; height: 200px; justify-content: center; align-items: center; background-color: #e9a9c7; color: #39464e; } </style> </head><body>` ) win.document.write(content) win.document.write('</body></html>') win.print() win.close() }

View on JSFiddle here. Note, the write method is synchronous, however sometimes window tries to print before write has finished, it happens only in some browsers ¬¬, therefore trying to avoid this we have added a setTimeout(). Yeah, no quite elegant but among all the different ways, it is the shortest that works across all updated browsers so far.

View, hide, type and generate password

Love to make things as simple as possible xD A hint just inside the input, then a button to show the password and finally another button to generate random passwords. HTML

View or hide password: JS

$view_password.addEventListener('click', e => { e.currentTarget.classList.toggle('view') if (e.currentTarget.className.includes('view')) $password.setAttribute('type', 'text') else $password.setAttribute('type', 'password') })

Set a random password and make sure it’s shown:

$generate_password.addEventListener('click', () => { $view_password.classList.add('view') $password.setAttribute('type', 'text') $password.value = Math.random().toString(36).slice(-8) })

View on JSFiddle here. Note, I personally name selector’s const starting with a $.

Infinite previous and next selection

Select each element in a selection loop. If you go forward as soon as you finish the list of elements you will start selecting from the beginning and the same if you go in opposite direction. HTML

<button id="previous">Previous</button> <button id="next">Next</button> <ul> <li></li> <li class="selected"></li> <li></li> <li></li> <li></li> </ul>

document.querySelector('#next').addEventListener('click', () => { const $selected = document.querySelector('.selected') const $next_element = $selected.nextElementSibling if (!$next_element) $next_element = $selected.parentElement.firstElementChild $selected.classList.remove('selected') $next_element.classList.add('selected') })

Remember, use nextElementSibling and previousElementSibling (DOM elements) instead of nextSibling and previousSibling (DOM objects). A DOM Object can be anything: comments, insolated text, line breaks, etc. In our example nextSibling would have worked if we had set all our HTML elements together without anything between then:

Responsive square

I have seen many weird ways to create responsive squares, that’s why I would like to share an easy one. Go to the JSFiddle link below and play resizing the result window. CSS

div { width: 60vw; height: 60vw; margin: 20vh auto; background-color: #774C60; }

Circle area defined by mouse click

We are going to define the area of a circle depending on where we click within a box area. We can handle this using JavaScript events, a little bit of basic maths and CSS. Width and height are igual, it doesn’t matter which we will set for our maths: JS

const width = e.currentTarget.clientWidth

Absolute position of the mouse cursor from the circle center:

const x = Math.abs(e.clientX — offset.left — width / 2) const y = Math.abs(e.clientY — offset.top — width / 2)

The maximum will tell us the percent of the circle area:

percent = Math.round(2 * Math.max(x, y) * 100 / width) $circle.style.width = percent + '%' $circle.style.height = percent + '%'

Text Overwriting

Well, maybe you are thinking that you can just turn on your Insert key from your keyboard but what If you don’t have it or if you want to always have an overwriting mode (independently) while typing in some specific inputs and textareas. You can do it easily. JS

$input.addEventListener('keypress', function(e) { const cursor_pos = e.currentTarget.selectionStart if (!e.charCode) return $input.value = $input.value.slice(0, cursor_pos) + $input.value.slice(cursor_pos + 1) e.currentTarget.selectionStart = e.currentTarget.selectionEnd = cursor_pos })

Counter with a reset using closures

Set up a basic counter with a closure and some external accessible options. JS

Remembler, a closure just let you keep recorded and protected your variables. View on JSFiddle here.

Infinite scroll

Have you ever seen those automatic "Load More" while you scroll down? Did you see them on Tumblr for images, Gmail for messages or Facebook? Cool, isn’t it? The infinite scroll is an alternative for pagination and it’s everywhere. It optimizes the user experience loading data as the user required it (indirectly). You get faster loading process for pages, web, apps and it just loads what you need instead of the whole bunch. You don’t need to add extra interactions, buttons or widgets because it comes with the normal reading behaviour that you are used to: scroll down with the mouse or with the finger in a touchable screen. JS

const $ol = document.querySelector('ol') function load_more() { let html = '' for (var i = 0; i < 5; i++) html += '<li></li>' $ol.innerHTML += html } $ol.addEventListener('scroll', function() { if ($ol.scrollHeight — $ol.scrollTop == $ol.clientHeight) load_more() })

View on JSFiddle here. Just notice in the example above that we could make it more efficient creating nodes and using appendChild().

Material icons

HTML

Basic CSS transition using box-shadow

Our CSS will change if the mouse is over the element with an ease-in-out transition effect (slow start and end). We are filling up the element with an inner shadow (inset) CSS

i { transition: all 0.5s ease-in-out; box-shadow: 0 0 0 75px #E94F37 inset; } i:hover { box-shadow: 0 0 0 4px #E94F37 inset; color:#E94F37; }

Export HTML table to CSV file

Imagine you have an HTML table and you want to download it as a CSV table. HTML

<table> <tr><th>Name</th><th>Age</th><th>Country</th></tr> <tr><td>Geronimo</td><td>26</td><td>France</td></tr> <tr><td>Natalia</td><td>19</td><td>Spain</td></tr> <tr><td>Silvia</td><td>32</td><td>Russia</td></tr> </table>

First of all, you need to transform from HTML to CSV: JS

let csv = [] let rows = document.querySelectorAll('table tr') for (var i = 0; i < rows.length; i++) { let row = [], cols = rows[i].querySelectorAll('td, th') for (var j = 0; j < cols.length; j++) row.push(cols[j].innerText) csv.push(row.join(',')) } download_csv(csv.join('\n'), filename)

After that, you can download it using Blob and a link:

let csvFile = new Blob([csv], {type: 'text/csv'}) let downloadLink = document.createElement('a') downloadLink.download = filename downloadLink.href = window.URL.createObjectURL(csvFile) downloadLink.style.display = 'none' document.body.appendChild(downloadLink) downloadLink.click()

View on JSFiddle here.

Keyboard events

Use event.code to get a human readable way of knowing which keys are pressed. Use event.key if you want to distinguish between capital letter or not, and avoid browser shortcuts, i.e: Ctrl + P (print) JS

document.onkeydown = event => { switch (event.code) { case ‘ArrowDown’: $div.style.top = `${parseInt($div.style.top || 0) + step}px` break case ‘KeyR’: if (event.altKey) $div.style.top = 0 break } }

View on JSFiddle here.

Short selectors like jQuery

Using JavaScript is some kind of annoying when you have to select DOM elements, in those cases we could miss jQuery because vanilla JavaScript is simply too long. JS

// Select one element (first one) document.querySelector('#peter') document.querySelector('.staff') document.querySelector('.staff').querySelector('.age') // Select all elements document.querySelectorAll('.staff')

We don’t like to repeat things when we are coding, if you define the next code at the beginning of your JavaScript you will be avaliable to do it similar even better than jQuery.

function $(selector) { return document.querySelector(selector) } function $$(selector) { return document.querySelectorAll(selector) } Element.prototype.$ = function(selector) { return this.querySelector(selector) } Element.prototype.$$ = function(selector) { return this.querySelectorAll(selector) }

Now you can write our example shorter:

// Select one element $('#peter') $('.staff') $('.staff').$('.age') // Select all elements $$('.staff')

It’s easy to keep in mind because $ behaves like jQuery with CSS selectors and $$ does the same but it allows you to select multiple elements. The first one return the element and the second one a list of elements. Just one more thing, you cannot use jQuery with this code because jQuery use $ too, if you need it you have to change the $ in our code for another thing, ie: qS. Remember, in JavaScript we have something better than classes: prototype. It doesn’t matter if you use class, under the hood is using prototype.

Which is the different between property and attribute?

A property is in the DOM; an attribute is in the HTML that is parsed into the DOM. HTML

document.body.onload = foo

Avoid switch statement when you don’t need logic

Arrays are faster, in the next example if you want to now which is the nineth month you can just code months[9]. JS

const months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']

How to Make a Simple JavaScript Quiz

"How do I make a JavaScript quiz?" is one of the most common questions asked by people learning web development, and for good reason. Quizzes are fun! They’re a great way of learning about new subjects, and they allow you to engage your audience with something fun and playful.

Coding your own JavaScript quiz is also a fantastic learning exercise. It teaches you how to deal with events, manipulate the DOM, handle user input, give feedback to the user and keep track of their score (for example, using client-side storage). And when you have a basic quiz up and running, there are a whole bunch of possibilities to add more advanced functionality, such as pagination. I go into this at the end of the article.

In this tutorial, I’ll walk you though creating a multi-step JavaScript quiz which you’ll be able to adapt to your needs and add to your own site. If you'd like to see what we'll be ending up with, you can skip ahead and see the working quiz.

Things to Be Aware of Before Starting

A few things to know before starting:

This is a front-end tutorial, meaning that anyone who knows how to look through the source code of a page can find the answers. For serious quizzes, the data needs to be handled through the back end, which is beyond the scope of this tutorial.

The code in this article uses modern JavaScript syntax (ES6+), meaning it will not be compatible with any versions of Internet Explorer. However, it will work just fine on modern browsers, including Microsoft Edge.

If you need to support older browsers, I've written a JavaScript quiz tutorial that's compatible back to IE8. Or, if you'd like a refresher on ES6, check out this course by Darin Haener over on SitePoint Premium.

You'll need some familiarity with HTML, CSS, and JavaScript, but each line of code will be explained individually.

The Basic Structure of Your JavaScript Quiz

Ideally, we want the quiz's questions and answers to be in our JavaScript code and have our script automatically generate the quiz. That way, we won't need to write a lot of repetitive markup, and we can add and remove questions easily.

To set up the structure of our JavaScript quiz, we'll need to start with the following HTML:

A <div> to hold the quiz

A <button> to submit the quiz

A <div> to display the results

Here's how that would look:

<div id="quiz"></div> <button id="submit">Submit Quiz</button> <div id="results"></div>

We can then select these HTML elements and store references to them in variables like so:

const quizContainer = document.getElementById('quiz'); const resultsContainer = document.getElementById('results'); const submitButton = document.getElementById('submit');

Next we'll need a way to build a quiz, show results, and put it all together. We can start by laying out our functions, and we'll fill them in as we go:

function buildQuiz(){} function showResults(){} // display quiz right away buildQuiz(); // on submit, show results submitButton.addEventListener('click', showResults);

Here, we have functions to build the quiz and show the results. We'll run our buildQuiz function immediately, and we'll have our showResults function run when the user clicks the submit button.

Displaying the Quiz Questions

The next thing our quiz needs is some questions to display. We'll use object literals to represent the individual questions and an array to hold all of the questions that make up our quiz. Using an array will make the questions easy to iterate over:

const myQuestions = [ { question: "Who invented JavaScript?", answers: { a: "Douglas Crockford", b: "Sheryl Sandberg", c: "Brendan Eich" }, correctAnswer: "c" }, { question: "Which one of these is a JavaScript package manager?", answers: { a: "Node.js", b: "TypeScript", c: "npm" }, correctAnswer: "c" }, { question: "Which tool can you use to ensure code quality?", answers: { a: "Angular", b: "jQuery", c: "RequireJS", d: "ESLint" }, correctAnswer: "d" } ];

Feel free to put in as many questions or answers as you want.

Note: as this is an array, the questions will appear in the order they’re listed. If you want to sort the questions in any way before presenting them to the user, check out our quick tip on sorting an array of objects in JavaScript.

Now that we have our list of questions, we can show them on the page. We'll go through the following JavaScript line by line to see how it works:

First, we create an output variable to contain all the HTML output including questions and answer choices.

Next, we can start building the HTML for each question. We'll need to loop through each question like so:

myQuestions.forEach( (currentQuestion, questionNumber) => { // the code we want to run for each question goes here });

For brevity, we're using an arrow function to perform our operations on each question. Because this is in a forEach loop, we get the current value, the index (the position number of the current item in the array), and the array itself as parameters. We only need the current value and the index, which for our purposes, we'll name currentQuestion and questionNumber respectively.

Now let's look a the code inside our loop:

// we'll want to store the list of answer choices const answers = []; // and for each available answer... for(letter in currentQuestion.answers){ // ...add an html radio button answers.push( `<label> <input type="radio" name="question${questionNumber}" value="${letter}"> ${letter} : ${currentQuestion.answers[letter]} </label>` ); } // add this question and its answers to the output output.push( `<div class="question"> ${currentQuestion.question} </div> <div class="answers"> ${answers.join('')} </div>` );

For each question, we'll want to generate the correct HTML, and so our first step is to create an array to hold the list of possible answers.

Next, we'll use a loop to fill in the possible answers for the current question. For each choice, we're creating an HTML radio button, which we enclose in a <label> element. This is so that users will be able to click anywhere on the answer text to select that answer. If the label was omitted, then users would have to click on the radio button itself, which is not very accessible.

Notice we're using template literals, which are strings but more powerful. We'll make use of the following features:

multi-line capabilities

no more having to escape quotes within quotes because template literals use backticks instead

string interpolation, so you can embed JavaScript expressions right into your strings like this: ${code_goes_here}.

Once we have our list of answer buttons, we can push the question HTML and the answer HTML onto our overall list of outputs.

Notice that we're using a template literal and some embedded expressions to first create the question div and then create the answer div. The join expression takes our list of answers and puts them together in one string that we can output into our answers div.

Now that we've generated the HTML for each question, we can join it all together and show it on the page:

quizContainer.innerHTML = output.join('');

Now our buildQuiz function is complete.

You should be able to run the quiz at this point and see the questions displayed. Please note, however, that the structure of your code is important. Due to something called the temporal dead zone, you can’t reference your questions array before it has been defined.

To recap, this is the correct structure:

// Functions function buildQuiz(){ ... } function showResults(){ ... } // Variables const quizContainer = document.getElementById('quiz'); const resultsContainer = document.getElementById('results'); const submitButton = document.getElementById('submit'); const myQuestions = [ ... ]; // Kick things off buildQuiz(); // Event listeners submitButton.addEventListener('click', showResults);

Displaying the Quiz Results

At this point, we want to build out our showResults function to loop over the answers, check them, and show the results.

Here's the function, which we'll go through in detail next:

First, we select all the answer containers in our quiz's HTML. Then we'll create variables to keep track of the user's current answer and the total number of correct answers.

// gather answer containers from our quiz const answerContainers = quizContainer.querySelectorAll('.answers'); // keep track of user's answers let numCorrect = 0;

Now we can loop through each question and check the answers.

// for each question... myQuestions.forEach( (currentQuestion, questionNumber) => { // find selected answer const answerContainer = answerContainers[questionNumber]; const selector = `input[name=question${questionNumber}]:checked`; const userAnswer = (answerContainer.querySelector(selector) || {}).value; // if answer is correct if(userAnswer === currentQuestion.correctAnswer){ // add to the number of correct answers numCorrect++; // color the answers green answerContainers[questionNumber].style.color = 'lightgreen'; } // if answer is wrong or blank else{ // color the answers red answerContainers[questionNumber].style.color = 'red'; } });

The general gist of this code is:

find the selected answer in the HTML

handle what happens if the answer is correct

handle what happens if the answer is wrong.

Let's look more closely at how we're finding the selected answer in our HTML:

// find selected answer const answerContainer = answerContainers[questionNumber]; const selector = `input[name=question${questionNumber}]:checked`; const userAnswer = (answerContainer.querySelector(selector) || {}).value;

First, we're making sure we're looking inside the answer container for the current question.

In the next line, we're defining a CSS selector that will let us find which radio button is checked.

Then we're using JavaScript's querySelector to search for our CSS selector in the previously defined answerContainer. In essence, this means that we'll find which answer's radio button is checked.

Finally, we can get the value of that answer by using .value.

Dealing with Incomplete User Input

But what if the user has left an answer blank? In this case, using .value would cause an error because you can't get the value of something that's not there. To solve this, we've added ||, which means "or", and {}, which is an empty object. Now the overall statement says:

Get a reference to our selected answer element OR, if that doesn't exist, use an empty object.

Get the value of whatever was in the first statement.

As a result, the value will either be the user's answer or undefined, which means a user can skip a question without crashing our quiz.

Evaluating the Answers and Displaying the Result

The next statements in our answer-checking loop will let us handle correct and incorrect answers.

// if answer is correct if(userAnswer === currentQuestion.correctAnswer){ // add to the number of correct answers numCorrect++; // color the answers green answerContainers[questionNumber].style.color = 'lightgreen'; } // if answer is wrong or blank else{ // color the answers red answerContainers[questionNumber].style.color = 'red'; }

If the user's answer matches the correct choice, increase the number of correct answers by one and (optionally) color the set of choices green. If the answer is wrong or blank, color the answer choices red (again, optional).

Once the answer-checking loop is finished, we can show how many questions the user got right:

// show number of correct answers out of total resultsContainer.innerHTML = `${numCorrect} out of ${myQuestions.length}`;

And now we have a working JavaScript quiz!

If you'd like, you can wrap the whole quiz in an IIFE (immediately invoked function expression), which is a function that runs as soon as you define it. This will keep your variables out of global scope and ensure that your quiz doesn't interfere with any other scripts running on the page.

(function(){ // put the rest of your code here })();

The best code snippets Wordpress for your website

Before publishing this post, we already know how to add PHP functions in Wordpress via using tools. However, I want to share with you some useful functions that either you or any web developers need to know for customising website. Furthermore, these functions can make your website more responsive, more security and more cool. In addition, these function can save your money (without using paid plugin), save much time for coding and test. Therefore, I create a list of 20 cool customised functions that can support you to select the most essential FUNCTIONS that you really need for your website. These functions are compatible with most popular themes and most of Wordpress versions. Besides, I will update more functions in this post for easy reviewing. In addition, the table of content on the right sidebar will support you to navigate easily. Before implementing the process, you need to concentrate on some important steps. READ THIS CAREFULLY BEFORE YOU GO Backup you website Separate each function below for testing before officially activating. You can use plugin snippets or other plugins or separated it in function.php. During testing, if it conflicts, incompatible or make errors on your theme, you can remove it, safely. You just copy and paste PHP code to snippet plugin and activate it. It begins with " " I already tested all codes below, It works like a charm. So if you have question or error code that need for support. You can leave your comment below. I will give you feedback asap. It could be including "How to use" and "CSS" parts. " " shows you how to display the function's result in html markup or insert it directly into posts. Therefore, you do not need to copy it into function.php or code snippet. Besides, " " supports you to decorate Html code block. Code snippets compatibility: Wordpress version > 4.6 PHP ~ 7.xx
