Try this:

    function getURLParameter(name, urlsearch) {

        return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(urlsearch || location.search) || [ , "" ])[1].replace(
                /\+/g, '%20'))
                || null;
    }

    var url = "Posts?Category=1134324";

    alert(getURLParameter('Category', url));
