Get URL Parameters Using JavaScript

This is really great! I ran across an article on netlobo.com that provides a short JavaScript function that allows one to access query string parameters the way you can in server-side programming.

“Most of the server-side programming languages that I know of like PHP, ASP, or JSP give you easy access to parameters in the query string of a URL. JavaScript does not give you easy access. With JavaScript you must write your own function to parse the window.location.href value to get the query string parameters you want. Here is a small function I wrote that will parse the window.location.href value and return the value for the parameter you specify. It does this using JavaScript’s built in regular expressions.”
