.split() not working as expected in IE8

Question

I\'m using the following to extract variables from a URL contained in a variable. It works fine in modern browsers but in IE8 it fails on the first variable but succeeds on

Answer 1

There have been some valid responses, but you may be interested in a function I use to retrieve GET parameters from URLs.

var get = function (name, url) { // Retrieves a specified HTTP GET parameter. Returns null if not found.
    url = (typeof (url) === "undefined" ? window.location.href : url);

    var regex = new RegExp("[?&]" + name + "=([^&#]*)");
    var results = regex.exec(url);
    var output = (results ? results[1] : null);

    return output;
};

You could use it like this.

var url = 'http://sagensundesign.com?height=400&width=300';

var h = get("height",url);
var w = get("width",url);
