Webshims Lib - The polyfilling, capability based loading JavaScript Library

Features

General Principles:

  • HTML5 compliant: correctly and accurately implemented (HTML5) Markup-, JS- and DOM-APIs
  • capability based loading: extremely lightweight in modern browsers
  • cross-browser support: All A-Graded browsers including latest version of Opera are tested
  • extendable: if we have not implemented a feature you want, you can easily implement it on your own

Implemented Features:

  • HTML5 shiv and innerShiv solution including basic CSS-support
  • canvas
  • HTML5 form features including: constraint validation and form widgets (input[range], input[date], input[time], input[datetime-local], output, input[list]/datalist)
  • HTML5 audio/video implementation
  • interactive elements: summary/details
  • JSON (stringify and parse)
  • localStorage/sessionStorage
  • geolocation
  • ECMAScript 5 / JavaScript 1.8.5 features

How To Use


<script src="js/jquery.js"></script>
<script src="js/Modernizr-yepnope.js"></script> 
<script src="js-webshim/minified/polyfiller.js"></script> 

<script> 
    //load and implement all unsupported features 
    $.webshims.polyfill();

    //or only load a specific feature
    //$.webshims.polyfill('geolocation json-storage');
</script>

  • Wait till everything has been loaded and then use it:

<script> 
    $(function(){
        //work with JSON and localStorage 
        var userData = JSON.parse(localStorage.getItem('userData')) || {visits: 0};
        $('#visits').html(userData.visits);
        //...
    });
</script>
