你如何触发＆QUOT;错误＆QUOT;回调jQuery的AJAX调用使用ASP.NET MVC？ [英] How do you trigger the "error" callback in a jQuery AJAX call using ASP.NET MVC?

问题描述

这是有关我的问题在如何从jQuery的处理错误AJAX调用。一些答复建议我用错误回调来显示一个jQuery AJAX调用任何错误。我不知道该怎么使用ASP.NET MVC的事情。有没有办法为我的控制器行动来回报，这将是从错误回调访问的错误？客户端code会是这个样子：

  $。阿贾克斯（{
   键入：POST，
   网址：MyUrl
   数据：VAL1 =测试，
   成功：函数（结果）{
        //做的东西
   }，
   错误：函数（请求，状态，errorThrown）{

   }
 }）;
 

解决方案

注：嘿，这是之前发布ASP.Net MVC连打1.0，从那以后，我还没有看的框架。你或许应该停止upvoting这一点。

做这样的事情：

  Response.Status code =（INT）的HTTPStatus code.BadRequest;
的ActionResult = this.Content（在此错误消息）;
 

根据错误的性质状态code应该改变;通常，4XX用户生成的问题和5XX服务器端的问题。

This is related to my question on how to handle errors from jQuery AJAX calls. Several responses suggested that I use the "error" callback to display any errors from a jQuery AJAX call. I was wondering how to do that using ASP.NET MVC. Is there a way for my controller action to return an error that would be accessible from the "error" callback? The client side code would look something like this:

$.ajax({
   type: "POST",
   url: "MyUrl",
   data: "val1=test",
   success: function(result){
        // Do stuff
   },
   error: function(request,status,errorThrown) {

   }
 });

解决方案

NOTE: Hey, this was posted before ASP.Net MVC even hit 1.0, and I haven't even looked at the framework since then. You should probably stop upvoting this.

Do something like this:

Response.StatusCode = (int)HttpStatusCode.BadRequest;
actionResult = this.Content("Error message here");

The status code should change depending on the nature of the error; generally, 4xx for user-generated problems and 5xx for server-side problems.
