This should be very simple (when you know the answer). From this question

I want to give the posted solution a try. My question is:

How to get the parameter value of a given URL using JavaScript regular expressions?

I have:

http://www.youtube.com/watch?v=Ahg6qcgoay4

I need: 

Ahg6qcgoay4

I tried:

http://www.youtube.com/watch\\?v=(w{11})

But: I suck...

I use seperate custom functions which gets all URL Parameters and URL parts . For URL parameters, (which is the final part of an URI String, http://domain.tld/urlpart/?x=a&y=b 

    function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
        vars[key] = value;
    });
    return vars;
    }

The above function will return an array consisting of url variables.

For URL Parts or functions, (which is http://domain.tld/urlpart/?x=a&y=b I use a simple uri split,

function getUrlParams() { 
    var vars = {};
    var parts = window.location.href.split('/' );
    return parts;
}

You can even combine them both to be able to use with a single call in a page or in javascript.
