ajax未调用到后台的action
页面源码没错，action的URL也没问题，直接在浏览器中调用该acion可正确执行。
但用ajax却无法调用，请大侠指导啊！！谢谢！！

ajax?struts2 spring ssh
[解决办法]
你$.ajax({
这个是需要jquery.js的，
没引用jquery.js
怎么调用
[解决办法]
按这个格式来试试：
$.ajax({
url:"",
type:"POST",
dataType:"json",
data:"",
success:function(data) {
}
});
[解决办法]
不用jquery的，你就用这段代码试试：
/**
* 操作ajax的对象
*/
var ajax = {
/**
* @see 创建ajax核心对象,兼容浏览器有：IE6,7,8,9,10，谷歌，火狐，欧朋，360极速，360安全，苹果，搜狗，遨游，猎豹，腾讯

}
} else {
if (window.ActiveXObject) {
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
}
}
if (xmlHttp == null) {
dv.alert("\u8bf7\u4f7f\u7528IE\u6d4f\u89c8\u5668!");
}
return xmlHttp;
},
remoteBack : null,// 跨域ajax的回调事件
core : null,// ajax的核心对象

}

} else {
info = param;
}
return info + "&" + randomStr;
