AJAX - 得到响应主体的成功和错误

问题描述

我道歉愚蠢的问题，但我需要你的帮助。我需要得到有关回应里面 AJAX 信息。

I am apologize for the stupid question, but I need your help. I need to get information about response inside AJAX.

$.ajax({
          type: "POST",
          url: '/register',
          data : registerRequestJSON,
          contentType:"application/json",
          success: function(data){
              $("#register_area").text();// need to show success
          },
          error: function(err) {
            $("#register_area").text("@text"); // @text = response error, it is will be errors: 324, 500, 404 or anythings else
          }
    });

我如何使用响应体？ （文档Jquary.Ajax 是不工作的momment）

How can I use response body? (documentation Jquary.Ajax is not working at the momment)

推荐答案

在第一个参数错误处理程序 jqxhr ，它具有这样的性质的responseText 这将给响应主体。

The first param to error handler is jqxhr, it has the property responseText which will give the response body.

$.ajax({
          type: "POST",
          url: '/register',
          data : registerRequestJSON,
          contentType:"application/json",
          success: function(data){
              $("#register_area").text();// need to show success
          },
          error: function(jqxhr) {
            $("#register_area").text(jqxhr.responseText); // @text = response error, it is will be errors: 324, 500, 404 or anythings else
          }
    });
