    Initial: function() { 

        var aPairs, aTmp; 

        var queryString = new String(window.location.search); 

        queryString = queryString.substr(1, queryString.length); //remove   "?"    

        aPairs = queryString.split("&"); 

        for (var i = 0; i < aPairs.length; i++) { 

            aTmp = aPairs[i].split("="); 

            this.data[aTmp[0]] = aTmp[1];
