前台js

复制代码 代码如下:

$("#nickForm").ajaxSubmit({

type: "post",

url: "http://localhost:8080/test/myspace.do?method=updateNick¶m=1",

dataType: "json",

success: function(result){

//返回提示信息

alert(result.nickMsg);

}

});

后台封装：

复制代码 代码如下:

public ActionForward toUpdateNickName(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response){

PrintWriter pw = response.getWriter();

JSONObject obj = new JSONObject();

obj.put("nickMsg", "昵称修改成功！");

pw.print(obj);

pw.close();

}
