React JS form validation

Introduction:

Form validation in React JS & Native Course ensures that the user inputs correct and complete information in your forms before submitting them. Here’s a simple guide to help you understand how to add validation to your forms in React.

Why Validate Forms?

Validating forms helps you:

Ensure the user inputs the required information.

Prevent incorrect or incomplete data submission.

Improve the user experience by guiding users on how to fill out the form correctly.

Setting Up Your Form

Let's create a basic form with fields for name and email. We will also add simple validation to check if these fields are filled out correctly.

Create the Form Component

First, create a new component for your form:

// Form.js import React, { useState } from 'react';

function Form() { const [name, setName] = useState(''); const [email, setEmail] = useState(''); const [errors, setErrors] = useState({});

const validate = () => { let formErrors = {}; if (!name) formErrors.name = "Name is required"; if (!email) formErrors.email = "Email is required"; else if (!/\S+@\S+.\S+/.test(email)) formErrors.email = "Email is invalid"; return formErrors; };

const handleSubmit = (e) => { e.preventDefault(); const formErrors = validate(); if (Object.keys(formErrors).length === 0) { console.log("Form submitted successfully!"); // Process form data here } else { setErrors(formErrors); } };

return ( Name:

setName(e.target.value)} /> {errors.name &&

{errors.name}} Email:

setEmail(e.target.value)} /> {errors.email &&

{errors.email}} Submit ); }

export default Form;

How It Works

State Management: We use useState to manage the state of the form inputs (name and email) and any validation errors.

Validation Function: The validate function checks if the fields are filled out and if the email is in the correct format.

Handle Submit: The handleSubmit function is called when the form is submitted. It prevents the default form submission, validates the inputs, and sets errors if there are any.

Displaying Errors: If there are validation errors, they are displayed below the respective input fields.

Adding More Validations:

You can add more validation rules as needed. For example, to check if the name is at least 3 characters long:

if (name.length < 3) formErrors.name = "Name must be at least 3 characters long";

To check if the email is in the correct format:

if (!/\S+@\S+.\S+/.test(email)) formErrors.email = "Email is invalid";

Summary:

Form validation in React JS helps ensure users fill out forms correctly before submitting. By using state to manage input values and validation errors, you can guide users to enter the right information. This simple setup can be expanded with more complex validation rules as needed.

Start adding validation to your React forms to improve data accuracy and user experience!

"Well, this is a bad idea," Tim says, hands on his hips as he surveys the mess they’ve made in the cave.

"Nah," Danny replies, twirling his screwdriver in the air in what is probably meant to be an impressive trick to inspire confidence, except he fumbles it and it clangs to the floor loudly, "we good. If a younger version of myself hasn't come forward in time to stop me, how bad can it be?"

"Shouldn't it be the other way round?"

"What?"

"Normally, it's an older version of yourself going backwards in time to stop you, right?"

"Not in my experience."

Danny's grin is impossibly feral and a shiver runs up Tim's spine.

"This is definitely a bad idea."

I'm so tired of the "English is a dumb bad language because it has no rules" take. It actually has quite a lot of rules, all of which make sense. You're just so lazy that you think the fact that not every function is uniform means that you shouldn't bother. It could be worse, you know. You could be dealing with agglutination. How does a three-line sentence that's only a single word sound to you? What about having to remember seven different words for "the"? We don't even have grammatical gender (which has nothing to do with human sex, like at all. Go check Irish's list of feminine and masculine words and prepare to be very confused). No declensions, barely any grammatical cases, no tones, no formal registers, and you're out here complaining that English is too hard because you keep forgetting that the past tense of "break" isn't "breaked". Sorry for that, but that's on you, not the language.

I really love Akin as a character. But because he is such a good character I simultaneously am endeared by his struggle to open himself up to Jin and also feeling the dread (tm) about his pride inevitably getting in the way.

He's so used to that external validation, but it's something that would have stopped eventually anyway so who better to be the one to "dethrone" him than Jin, the man who admires him and loves him?

You see Akin start to toy with the idea that maybe there could be happiness in his life while being his authentic self, but at the same time you can feel how fragile he is, how difficult it is for him to find value in himself if he's not the center of the public's attention.

It could come off as obnoxious or petty, but when you see him contrasted with Jin who is so self assured, so comfortable in his own skin, so able to take criticism or scrutiny, it's impossible to not sympathize with Akin.

If you always believe you are one step away from not measuring up, how do you love the person whose mere existence incites comparisons where you fall short?

I don’t usually do this because I have a pretty thick skin and not much bothers me…

But this is just a little PSA warning for ep. 6 of Top Form.. particularly cause I think a lot of us got lulled into a false sense of security after ep. 4.

It’s (at least it was for me) really difficult to watch.

Johnny is a predator and Akin is raped (off screen, but is assaulted on screen). He is a victim.

And I have to say, just like… as a woman (I can only speak to my experience) the scenario they depict is the scariest thing imaginable. Because it’s very real. And unfortunately.. very common.

Props to the production team for handling it in a way that didn’t over dramatize or play it for shock value, but fuck… it turned my stomach and my heart is absolutely broken for Akin.

Regardless of how I or anyone else feels about Gale's abs, imagining how the companions would react upon discovering the nerdy yappy wizard with bad knees is secretly RIPPED underneath all those robes will never not be hilarious to me.

But how do you think Gale would respond to everyone losing their minds the first time circumstance demands he be shirtless around others? Like maybe his robe got shredded in battle, or someone hid his pjs as a prank while he bathed in the river. Would he be flustered? Smug? Confused? All of the above? Presuming this happens in Act 1 when he's fervently pining for Tav from afar, what would a positive reaction from them do to his brain?

(to keep this in the realm of humorous, this is assuming his abs aren't due to malnutrition/dehydration from the orb. Which is a perfectly valid headcanon, but would take this scenario in a far more sobering direction)

Ahahah, you and I are on the same page Anon! I actually wrote a scenario about the other companions reacting to Gale’s abs!

I think Gale—while secretly pleased at the attention—would be a little embarrassed by all the comments from the other companions, and would try and downplay the situation: “Come now, it can’t be THAT big of a surprise to you all? I’m not lolling about on the battlefield you know!”

This is a man who gets flustered if Tara is in the room when he changes clothes, after all. He’s not exactly cool and breezy about showing off his body.

…but if Tav were to make comments? Complimentary comments? FLIRTY COMMENTS?? 😳 Well! Oh my! Gale would be most pleased to hear it!

I do think he would be a little smug/proud about it. He’d greatly enjoy getting a little boost of confidence from it, especially in Act 1, by allowing himself to think that perhaps Tav really does like him as much as he likes them. Maybe that lovely plunging neck outfit that he wears in the Epilogue would make an early appearance. Or perhaps his robes would suddenly be a tad more revealing with an unbuttoned, open chest.

Regardless, Tav would be sure to compliment him each time, because seeing his cheeks flush with pleasure would be the perfect pairing with those impressive abs 👀
