对象#< XMLHttpRequest>没有方法' done' [英] Object #<XMLHttpRequest> has no method 'done'

问题描述

我正在尝试实现简单的ajax GET request.在回调部分，我想调用一些函数.代码如下

I was trying to implement simple ajax GET request . In the callback portion i want to call some function . The code is as below

$.ajax({
          url: "<?php echo SITE_URL?>ajax_pages/ajx_getcard.php?id="+obj.value,
          context: document.body
        }).done(function() { 
          $(this).addClass("done");
        });

但是它显示了异常

未捕获的TypeError:对象#没有方法完成" replace_entry.php:105 getCardno replace_entry.php:105 onblur replace_entry.php:118

Uncaught TypeError: Object # has no method 'done' replace_entry.php:105 getCardno replace_entry.php:105 onblur replace_entry.php:118

推荐答案

您可能正在使用旧版本的jQuery-新版本返回

You are probably using an old version of jQuery - new versions return a jqXHR object, that does have done.
You can quickly check your version by looking at the source, or typing $().jquery into your console.

如果无法升级，则降级的代码应为:

If you cannot upgrade, the downgraded code should be:

$.ajax({
      url: "...",
      context: document.body,
      complete: function() { 
           $(this).addClass("done");
      });
