问题描述：

how do i define the success and failure function of an ajax $.post?

答

但是，总而言之，ajax调用需要很多选择.您要寻找的是错误和成功.

But, to summarize, the ajax call takes a bunch of options. the ones you are looking for are error and success.

您会这样称呼它:

$.ajax({
  url: 'mypage.html',
  success: function(){
    alert('success');
  },
  error: function(){
    alert('failure');
  }
});

我已经展示了成功和错误函数不带参数，但是它们可以接收参数.

I have shown the success and error function taking no arguments, but they can receive arguments.

错误函数可以采用三个参数:XMLHttpRequest，textStatus和errorThrown.

The error function can take three arguments: XMLHttpRequest, textStatus, and errorThrown.

成功函数可以使用两个参数:data和textStatus.您请求的页面将在data参数中.

The success function can take two arguments: data and textStatus. The page you requested will be in the data argument.
