EasyUi1.4 form 提交问题，请熟悉的高手解答

[XiaoQiang11s]

form提交后，如果后台打断点，页面不等后台响应，会执行：alert("服务器维护中，请稍后再试！");
为什么呢？我的后台还没有成功响应呢，页面怎么能获取响应数据的？

$('#DzMediumRegister').form('submit', {
url : 'registerAction!register.action',
onSubmit : function(param) {
param.regType = mediunRegType;
param.wtms = $('#e_safeQuestions').combobox('getText');
if(mediunRegType =="12"){//邮箱注册
_email = $("#vv").val();
}
if(mediunRegType =="11"){
_mobile = $("#zjmobile").val();
}
//return true;
return $(this).form('validate');//对数据进行格式化
},
success : function(data) {
if(jQuery.isEmptyObject(data)){
alert("服务器维护中，请稍后再试！");
}
var obj = jQuery.parseJSON(data);
if (obj.Success) {
if(mediunRegType =="12"){//邮箱注册
location.href = "<%=basePath%>jquery-easyui-1.4/demo/register2.jsp? yhbm="+obj.yhbm+"&email="+obj.email;
}else if(mediunRegType =="11"){
location.href = "<%=basePath%>jquery-easyui-1.4/demo/register2.jsp?yhbm="+obj.yhbm+"&mobile="+obj.mobile;
}
}
}
});

发现了问题，IE下正常，360浏览器下报 Error in response to storage.get: TypeError: Cannot read property 'shoptemplate' of undefined at Object.tpl.loadPageTplData (chrome-extension://dobbgecnokkloebjbcnjpgcopegjabpa/js/box.js:1:8515) at Object.tpl.getPageTplData (chrome-extension://dobbgecnokkloebjbcnjpgcopegjabpa/js/box.js:1:6017) at chrome-extension://dobbgecnokkloebjbcnjpgcopegjabpa/js/box.js:1:11664 at Object.callback (chrome-extension://dobbgecnokkloebjbcnjpgcopegjabpa/js/box.js:1:1232) extensions::sendRequest:26 safeCallbackApply extensions::sendRequest:26 handleResponse 难道360出现兼容问题？？？？？ 你们遇到过吗？
