Javascript Everyone Should Know - Iterating URL Args

Here's some javascript I'm often looking for, because I can't remember it off the cuff after 3 months of LINQ coding and I've started writing something where JQuery isn't available...

It iterates through all the parameters and their arguments passed in the URL...

var url = window.location.toString();
var query_string = url.split('?')[1];
var params = query_string.split("&");
for (var i = 0; i < params.length; i++)
{
var name = params[i].split("=")[0];
var arg = params[i].split("=")[1];
alert(i+': '+name+' = '+unescape(arg));
}
