Publisher review:Prototype is a JavaScript Framework that aims to ease development of dynamic web applications. Prototype is a JavaScript Framework that aims to ease development of dynamic web applications. Featuring a unique, easy-to-use toolkit for class-driven development and the nicest Ajax library around, Prototype is quickly becoming the codebase of choice for web application developers everywhere.
Prototype framework enables you to deal with Ajax calls in a very easy and fun way that is also safe (cross-browser). Besides simple requests, this module also deals in a smart way with JavaScript code returned from a server and provides helper classes for polling.
The biggest part of the Prototype framework are its DOM extensions. Prototype adds many convenience methods to elements returned by the $() function: for instance, you can write $('comments').addClassName('active').show() to get the element with the ID 'comments', add a class name to it and show it (if it was previously hidden).
The 'comments' element didn't have those methods in native JavaScript; how is this possible? This document reveals some clever hacks found in Prototype.
JSON (JavaScript Object Notation) is a lightweight data-interchange format (if you are new to JSON, you can read more about it on the JSON website). It is notably used by APIs all over the web and is a fast alternative to XML in Ajax requests. Prototype 1.5.1 finally features JSON encoding and parsing support.
Prototype 1.7.2.0 is a JavaScript script for Development Tools scripts design by Prototype Core Team.
