jquery获得 url的变量

(function($){
    $.extend({
        urlGet:function () {
            var aQuery = window.location.href.split("?");//取得Get参
            var test = window.location.href;
            var aGET = new Array();
            if(aQuery.length > 1){
                var aBuf = aQuery[1].split("&");
                for(var i=0, iLoop = aBuf.length; i<iLoop; i++){
                    var aTmp = aBuf[i].split("=");//分离key与Value
                    aGET[aTmp[0]] = aTmp[1];
                }
            }
            return aGET;
        }
    });
})(jQuery);
