Use the get parameter of the url in javascript

Suppose I have this url:

s = 'http://mydomain.com/?q=microsoft&p=next'

In this case, how do I extract "microsoft" from the string? I know that in python, it would be:

new_s = s[s.find('?q=')+len('?q='):s.find('&',s.find('?q='))]

Answer 1

I use the parseUri library available here: http://stevenlevithan.com/demo/parseuri/js/

It allows you to do exactly what you are asking for:

var uri = 'http://mydomain.com/?q=microsoft&p=next';
var q = uri.queryKey['q'];
// q = 'microsoft'

Answer 2

(function(){

    var url = 'http://mydomain.com/?q=microsoft&p=next'
    var s = url.search.substring(1).split('&');

    if(!s.length) return;

    window.GET = {};

    for(var i  = 0; i < s.length; i++) {

        var parts = s[i].split('=');

        GET[unescape(parts[0])] = unescape(parts[1]);

    }

}())

Think this will work..
