[Web Technology] 2 - Prototype

<Prototype>

Introduction of Prototype

• It is implemented as a single file of JavaScript code, usually named prototype.js. 
• The features range from programming shortcuts to major functions for dealing with XMLHttpRequest.
• Prototype also provides library functions to support classes and class-based objects.
• Unlike other JavaScript libraries like jQuery, Prototype extends the DOM

Use $() function to replace document.getElementById(). Like,

var myElement = $(’elementid’);

Every line of Prototype code has to be carefully rewritten - carefully especially because many helper functions and constructs ($ $$) look deceivingly similar.
