Get url parameter with jquery

Question

I want to read out an url parameter using jquery and bind this one in a variable. I've seen a lot of ways to solve it but definitely no one worked for me.

-> I'm using a '#' instead of a '&' or '?'!

This is my current javascript:

function $_GET(param) {
    var vars = {};
    window.location.href.replace( location.hash, '' ).replace( 
        /[?&]+([^=&]+)=?([^&]*)?/gi, // regexp
        function( m, key, value ) { // callback
            vars[key] = value !== undefined ? value : '';
        }
    );

    if ( param ) {
        return vars[param] ? vars[param] : null;    
    }
    return vars;
}

var filter = $_GET('filter');

Answer 1

var url = window.location.href;
var arguments = url.split('#')[1].split('=');
arguments.shift();

Working Example

var url = "http://relaunch.headonline.de/projekte/#filter=kataloge-database";
var arguments = url.split('#')[1].split('=');
arguments.shift();
alert(arguments)
