问题描述

 $.ajax({
         url: urlString,
         dataType: "json",
         type: "GET",
         success: function (data) {

             } else if (jqXHR.status == 404) {
                 alert('Requested page not found. [404]');
             } else if (jqXHR.status == 500) {
                 alert('Internal Server Error [500].');
             } else if (exception === 'parsererror') {
                 alert('Requested JSON parse failed.');
             } else if (exception === 'timeout') {
                 alert('Time out error.');
             } else if (exception === 'abort') {
                 alert('Ajax request aborted.');
             } else {
                 alert('Uncaught Error.\n' + jqXHR.responseText);
             }

         }
     });

这是利用即时通讯来访问服务器的一些信息，我的JavaScript文件。该urlString提供和正确。我所做的就是下载的，我是检索服务器的.json并在本地计算机上访问它。当我去到从服务器访问文件我不断收到jqXHR.status == 0错误。我不知道如何解决这个问题，因为我看不出什么毛病我code。

This is my javascript file that im using to access some information from a server. The urlString is supplied and is correct. What I did was download the .json from the server that I was retrieving and accessed it locally on my computer. When I go to access the file from the server I keep getting jqXHR.status==0 error. I'm not sure how to fix that because I can't see anything wrong with my code.

有人点我在正确的方向来解决我的错误？

Can someone point me in the right direction to fix my error?

推荐答案

，你得到不同的状态codeS的是，该文件是不与 HTTP牵强的理由：协议，但与文件：的协议。这是自然的，不同的协议有不同的状态codeS。

The reason that you get different status codes is that the file isn't fetched with the http: protocol but with the file: protocol. It's natural that different protocols have different status codes.

您只需要有不同的行为取决于你在哪里获取的文件。

You simply need to have different behaviour depending on where you fetch the file from.

有一个这个，其中被标记为无效的Mozilla bug报告因为这被认为是正确的结果。

There is a Mozilla bug report about this, which is marked as invalid because this is considered to be the correct result.
