MYAPP.getUrlParam=function() {
        var url = location.search; //獲取url中"?"符後的字串
        var theRequest = new Object();
        if (url.indexOf("?") != -1) {
            var str = url.substr(1);
            strs = str.split("&");
            for(var i = 0; i < strs.length; i ++) {
                theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
            }
        }
        return theRequest;
