Parse URL with jquery/ javascript?

How do I parse an url with jquery/ javascript?

For instance I have this in my string,

http://mysite.com/form_image_edit.php?img_id=33

I want to get the value of img_id







You can use a trick of creating an a-element, add the url to it, and then use its Location object.

function parseUrl( url ) {
    var a = document.createElement('a');
    a.href = url;
    return a;
}

parseUrl('http://mysite.com/form_image_edit.php?img_id=33').search

Which will output: ?img_id=33
