Two Ways to Create Custom Translated Messaging for HTML Forms

HTML forms come with built-in ways to validate form inputs and other controls against predefined rules such as making an input required, setting min and max constraints on range sliders, or establishing a pattern on an email input to check for proper formatting. Native HTML and browsers give us a lot of “free” features that don’t require fancy scripts to validate form submissions.

And if something doesn’t properly validate? We get “free” error messaging to display to the person using the form.

These are usually good enough to get the job done, but we may need to override these messages if we need more specific error content — especially if we need to handle translated content across browsers. Here’s how that works.

The Constraints API

The Constraints API is used to override the default HTML form validation messages and allows us to define our own error messages. Chris Ferdinandi even covered it here on CSS-Tricks in great detail.

In short, the Constraints API is designed to provide control over input elements. The API can be called at individual input elements or directly from the form element.

For example, let’s say this simple form input is what we’re working with:

<form id="myForm">   <label for="fullName">Full Name</label>   <input type="text" id="fullName" name="fullName" placeholder="Enter your full name" required>   <button id="btn" type="submit">Submit</button> </form>

We can set our own error message by grabbing the <input> element and calling the setCustomValidity() method on it before passing it a custom message:

const fullNameInput = document.getElementById("fullName"); fullNameInput.setCustomValidity("This is a custom error message");

When the submit button is clicked, the specified message will show up in place of the default one.

Translating custom form validation messages

One major use case for customizing error messages is to better handle internationalization. There are two main ways we can approach this. There are other ways to accomplish this, but what I’m covering here is what I believe to be the most straightforward of the bunch.

Method 1: Leverage the browser’s language setting

The first method is using the browser language setting. We can get the language setting from the browser and then check whether or not we support that language. If we support the language, then we can return the translated message. And if we do not support that specific language, we provide a fallback response.

Continuing with the HTML from before, we’ll create a translation object to hold your preferred languages (within the script tags). In this case, the object supports English, Swahili, and Arabic.

const translations =   en:     required: "Please fill this",     email: "Please enter a valid email address",     ,   sw:     required: "Sehemu hii inahitajika",     email: "Tafadhali ingiza anwani sahihi ya barua pepe",   ,   ar:     required: "هذه الخانة مطلوبه",     email: "يرجى إدخال عنوان بريد إلكتروني صالح",   ;

Next, we need to extract the object’s labels and match them against the browser’s language.

// the translations object const supportedLangs = Object.keys(translations); const getUserLang = () =>   // split to get the first part, browser is usually en-US   const browserLang = navigator.language.split('-')[0];   return supportedLangs.includes(browserLang) ? browserLang :'en'; ; // translated error messages const errorMsgs = translations[getUserLang()];// form element const form = document.getElementById("myForm");// button elementconst btn = document.getElementById("btn");// name input const fullNameInput = document.getElementById("fullName");// wrapper for error messaging const errorSpan = document.getElementById("error-span"); // when the button is clicked… btn.addEventListener("click", function (event)   // if the name input is not there…   if (!fullNameInput.value)     // …throw an error     fullNameInput.setCustomValidity(errorMsgs.required);    // set an .error class on the input for styling     fullNameInput.classList.add("error");   );

Here the getUserLang() function does the comparison and returns the supported browser language or a fallback in English. Run the example and the custom error message should display when the button is clicked.

Method 2: Setting a preferred language in local storage

A second way to go about this is with user-defined language settings in localStorage. In other words, we ask the person to first select their preferred language from a <select> element containing selectable <option> tags. Once a selection is made, we save their preference to localStorage so we can reference it.

<label for="languageSelect">Choose Language:</label> <select id="languageSelect">   <option value="en">English</option>   <option value="sw">Swahili</option>   <option value="ar">Arabic</option> </select> <form id="myForm">   <label for="fullName">Full Name</label>   <input type="text" id="fullName" name="fullName" placeholder="Enter your full name" required>   <span id="error-span"></span>   <button id="btn" type="submit">Submit</button> </form>

With the <select> in place, we can create a script that checks localStorage and uses the saved preference to return a translated custom validation message:

// the <select> element const languageSelect = document.getElementById("languageSelect"); // the <form> element const form = document.getElementById("myForm"); // the button element const btn = document.getElementById("btn"); // the name input const fullNameInput = document.getElementById("fullName"); const errorSpan = document.getElementById("error-span"); // translated custom messages const translations =   en:     required: "Please fill this",     email: "Please enter a valid email address",   ,   sw:     required: "Sehemu hii inahitajika",     email: "Tafadhali ingiza anwani sahihi ya barua pepe",   ,   ar:     required: "هذه الخانة مطلوبه",     email: "يرجى إدخال عنوان بريد إلكتروني صالح",   ; // the supported translations object const supportedLangs = Object.keys(translations); // get the language preferences from localStorage const getUserLang = () =>   const savedLang = localStorage.getItem("preferredLanguage");   if (savedLang) return savedLang;   // provide a fallback message   const browserLang = navigator.language.split('-')[0];   return supportedLangs.includes(browserLang) ? browserLang : 'en'; ; // set initial language languageSelect.value = getUserLang(); // update local storage when user selects a new language languageSelect.addEventListener("change", () =>   localStorage.setItem("preferredLanguage", languageSelect.value); ); // on button click btn.addEventListener("click", function (event)   // take the translations   const errorMsgs = translations[languageSelect.value];   // ...and if there is no value in the name input   if (!fullNameInput.value)     // ...trigger the translated custom validation message     fullNameInput.setCustomValidity(errorMsgs.required);     // set an .error class on the input for styling     fullNameInput.classList.add("error");   );

The script sets the initial value to the currently selected option, saves that value to localStorage, and then retrieves it from localStorage as needed. Meanwhile, the script updates the selected option on every change event fired by the <select> element, all the while maintaining the original fallback to ensure a good user experience.

If we open up DevTools, we’ll see that the person’s preferred value is available in localStorage when a language preference is selected.

Wrapping up

And with that, we’re done! I hope this quick little tip helps out. I know I wish I had it a while back when I was figuring out how to use the Constraints API. It’s one of those things on the web you know is possible, but exactly how can be tough to find.

よく「発明は1人でできる。製品化には10人かかる。量産化には100人かかる」とも言われますが、実際に、私はネオジム磁石を1人で発明しました。製品化、量産化については住友特殊金属の仲間たちと一緒に、短期間のうちに成功させました。82年に発明し、83年から生産が始まったのですから、非常に早いです。そしてネオジム磁石は、ハードディスクのＶＣＭ(ボイスコイルモーター)の部品などの電子機器を主な用途として大歓迎を受け、生産量も���々倍増して、2000年には世界で1万トンを超えました。

The Delian League, Part 2: From Eurymedon to the Thirty Years Peace (465/4-445/4 BCE)

This text is part of an article series on the Delian League.

The second phase of the Delian League's operations begins with the Hellenic victory over Mede forces at Eurymedon and ends with the Thirty Years Peace between Athens and Sparta (roughly 465/4 – 445/4 BCE).The Greek triumph at Eurymedon resulted in a cessation of hostilities against the Persians, which lasted almost six years. Whether or not this peace or truce followed from some formal treaty negotiated by Cimon, son of Miltiades, remains unknown.

Nevertheless, the Greek success at Eurymedon proved so decisive, the damage inflicted on Persia so great, and the wealth confiscated so considerable that an increasing number of League members soon began to wonder if the alliance still remained necessary. The Persians, however, had not altogether withdrawn from the Aegean. They still had, for example, a sizeable presence in both Cyprus and Doriscus. They also set about to build a great number of new triremes.

REDUCTION OF THASOS & THE BATTLE OF DRABESCUS

A quarrel soon erupted between the Athenians and Thasians over several trading ports and a wealth-producing mine (465 BCE). Competing economic interests compelled the rich and powerful Thasos to revolt from the Delian League. The Thasians resisted for almost three years. When the polis finally capitulated, the Athenians forced Thasos to surrender its naval fleet and the mine, dismantle defensive walls, pay retributions, and converted the future League contributions to monetary payments: 30 talents annum. Some League members became disaffected with the Athenian reduction of Thasos. Several poleis observed the Athenians had now developed a penchant for using "compulsion." They started to see Athens acting with both "arrogance and violence." On expeditions, furthermore, the other members felt they "no longer served as equals" (Thuc. 1.99.2).

The Athenians, meanwhile, attempted to establish a colony on the Strymon river to secure timber from Macedon, which shared its borders with the west bank. The location also proved a critical strategic point from which to protect the Hellespont. The Thracians, however, repelled the League forces at Drabescus. The Athenians soon realized the threats from both Thrace and Macedon made permanent settlements in the region difficult as they were essentially continental powers, and the League fleet could not reach them easily. Designs for the region, however, would not change, and the Athenians would return there again.

The Delian League had by this time demonstrated an inherent conflict from its beginnings: on the one hand, it engaged in heroic struggles against the Mede and extended its influence, reaping enormous benefits (especially for its poorer members). On the other hand, it also suppressed its members and soon demanded obedience from them.

The League engaged from the outset in a form of soft imperialism, collecting and commanding voluntary naval contributions and tribute while Athens used those resources and led all expeditions, enforcing continued membership but also showing little or no interest to interfere with the internal mechanisms of any member polis (unless it openly rebelled).
