jQuery的：有jQuery中故障处理程序$。员额？ [英] jquery: is there a fail handler for $.post in Jquery?

问题描述

在$ .post的成功，有成功的处理程序。如果失败了怎么办？是否有一个类似的处理程序，我们可以利用这种情况，以便我们能够告知自己是不是发生了吗？用户

When $.post succeeds, there is a success handler for it. What happens if it fails? Is there a similar handler that we can use for this case, so that we can inform the user that something is not happening right?

推荐答案

还有，是不是按照文档，对于 $。后一个特定的错误处理程序方法。

There is not, according to the documentation, a specific error handler for $.post method.

您需要做什么，如果你想同时拥有成功和失败的处理程序，是使用低级别的 $。阿贾克斯方法。它的文档可以在这里找到： http://api.jquery.com/jQuery.ajax/

What you have to do, if you want to have both the success and fail handlers, is to use the low-level $.ajax method. It's documentation can be found here: http://api.jquery.com/jQuery.ajax/

$.ajax({
  type: "POST",
  url: "some.php",
  success: function(html){
    /* Do success stuff here */
  },
  error: function(){
    /* do error stuff here */
  }
});
