Javascript URL Parser

Published in: JavaScript 

URL: http://jrharshath.wordpress.com/

This is a script that can parse a URL string, and return all components in a systematic way via an object. This script is very useful in places where you want to link to a page "dynamically" generated by javascript. This is usually done by adding GET-like params after a # in the URL.

This parser can parse URLs like:

* http://jrharshath.com/
* http://jrharshath.com/page?param=value
* http://jrharshath.com/page?param=value&param2=value2
* http://jrharshath.com/some?serverparam=somevalue#JSFeature?param=val&param2=val2
* http://jrharshath.com/some?serverparam=somevalue#AjaxPage?param=val&param2=val2#AnotherAjaxFeature?featureparam=featureval
