AJAX - 获得成功和错误的响应体

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

我为这个愚蠢的问题道歉，但我需要你的帮助。我需要获取有关AJAX内部响应的信息。

$.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
          }
    });

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

我怎样才能使用响应体？ （文档Jquary.Ajax不在妈妈的工作）

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

错误处理程序的第一个参数是jqxhr，它具有属性responseText，它将给出响应体。

$.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
          }
    });
