    A jQuery plugin that makes it easy to i18n your static web site.


    • Lazily loads JSON translation files based on a simple naming convention.
    • By default, applies the translations to your document based on simple attribute convention.
    • Tested with jQuery versions 1.7.2, 1.8.3, 1.9.1, 1.10.2, 1.11.0, 2.0.3, 2.1.0

    Getting Started

    Download the production version or the development version.

    Load the jquery-localize plugin on your page.

    It's the file located at dist/jquery.localize.js

    Mark up tags whose content you want to be translated

    Somewhere in your html:

    <h1 data-localize="greeting"> Hello! </h1>

    Provide a JSON language file that has translations:


      "greeting": "Bonjour!"

    Use the localize plugin.

    // In a browser where the language is set to French
    // You can also override the language detection, and pass in a language code
    $("[data-localize]").localize("example", { language: "fr" })

    Language file loading

    The first argument of the localize method is the name of the language pack. You might have a different language pack for different parts of your website.

    Here's an example of loading several language packs:


    If the language of the browser were set to "fr", then the plugin would try to load:

    • header-fr.json
    • sidebar-fr.json
    • footer-fr.json

    if the language of the browser also had a country code, like "fr-FR", then the plugin would ALSO try to load:

    • header-fr-FR.json
    • sidebar-fr-FR.json
    • footer-fr-FR.json

    This let's you define partial language refinements for different regions. For instance, you can have the base language translation file for a language that translates 100 different phrases, and for countries were maybe a some of those phrases would be out of place, you can just provide a country-specific file with just those special phrases defined.

    Skipping Languages (aka Optimizing for My Language)

    This is useful if you've got a default language. For example, if all of your content is served in english, then you probably don't want the overhead of loading up unecessary (and probably non-existant) english langauge packs (foo-en.json)

    You can tell the localize plugin to always skip certain languages using the skipLanguage option:

    //using a string will skip ONLY if the language code matches exactly
    //this would prevent loading only if the language was "en-US"
    $("[data-localize]").localize("example", { skipLanguage: "en-US" })
    //using a regex will skip if the regex matches
    //this would prevent loading of any english language translations
    $("[data-localize]").localize("example", { skipLanguage: /^en/ })
    //using an array of strings will skip if any of the strings matches exactly
    $("[data-localize]").localize("example", { skipLanguage: ["en", "en-US"] })

    Applying the language file

    If you rely on the default callback and use the "data-localize" attribute then the changes will be applied for you.



    <p data-localize="title">Tracker Pro XT Deluxe</p>
    <p data-localize="search.placeholder">Search...</p>
    <p data-localize="search.button">Go!</p>
    <p data-localize="footer.disclaimer">Use at your own risk.</p>
    <p data-localize="menu.dashboard">Dashboard</p>
    <p data-localize="menu.list">Bug List</p>
    <p data-localize="menu.logout">Logout</p>

    application-es.json (fake spanish)

      "title": "Tracker Pro XT Deluxo",
      "search": {
        "placeholder": "Searcho...",
        "button": "Vamos!"
      "footer": {
        "disclaimer": "Bewaro."
      "menu": {
        "dashboard": "Dashboardo",
        "list": "Bug Listo",
        "logout": "Exito"

    Localize it!

    $("[data-localize]").localize("application", { language: "es" });


    You can provide a callback if you want to augment or replace the default callback provided by the plugin. Your callback should take at least 1 argument: the language data (contents of your json file). It can optionally accept a second argument, which is a reference to the default callback function. This is handy if you still want the default behavior, but also need to do something else with the language data.

    $("[data-localize]").localize("application", {
        language: "es",
        callback: function(data, defaultCallback){
            data.title = data.title + currentBugName();

    See the test/samples for working examples.
