window.location.search.replace("?", "").split("&")[0];

update:

in case there's a variable holding url:

url.substring(url.lastIndexOf("?") + 1).split("&")[0];

Ugh, there's got to be a better way to do this. URL parsing aren't easy.

URL parsing yes, there are variety of Schemes, Ports, Hosts and IPs to accomplish this URL pattern, However Query String pattern in Http binding is fairly simple

You can use a regular expression to read out parts of the URL:

window.location.search.match(/\?([^&$]+)/)[1] // == 'ix=teb'

In the event that there isn't anything in the query string of the URL, this would cause an error, so you should include some type checking like:

var queryStringMatch = window.location.search.match(/\?([^&$]+)/);
if(queryStringMatch) {
   // do something with queryStringMatch[1]
}
