jQuery Plugin For Universal Language Selector - ULS

ULS is a jQuery plugin that allows you to implement a clean Wikimedia Universal Language Selector on your website.

How to use it:

1. Include the latest jQuery library on your website

<script src="/path/to/cdn/jquery.min.js"></script>

2. Include necessary jQuery ULS files on the page

<link href="../css/jquery.uls.css" rel="stylesheet"/>
<link href="../css/jquery.uls.grid.css" rel="stylesheet"/>
<link href="../css/jquery.uls.lcd.css" rel="stylesheet"/>
<script src="../src/jquery.uls.data.js"></script>
<script src="../src/jquery.uls.data.utils.js"></script>
<script src="../src/jquery.uls.lcd.js"></script>
<script src="../src/jquery.uls.languagefilter.js"></script>
<script src="../src/jquery.uls.regionfilter.js"></script>
<script src="../src/jquery.uls.core.js"></script>

3. Create a container for the Language Selector

<span class="active uls-trigger">Select Language</span>

4. Initialize the plugin on the trigger element.

    onSelect: function(language){
      var languageName = $.uls.data.getAutonym(language);
      $( '.uls-trigger' ).text( languageName );
    quickList: ['en', 'hi', 'he', 'ml', 'ta', 'fr']
