使用jQuery AJAX显示正确的错误消息 [英] Show proper error messages with jQuery AJAX

问题描述

当前，如果我对ajax请求有错误，例如提交表单(我正在使用ASP.NET MVC 3)，它将显示类似内部服务器错误"的信息.

Currently if I have an error with an ajax request such as submitting a form (I'm using ASP.NET MVC 3) it will show something like 'Internal Server Error'.

但是，如果我不使用Ajax进行提交，则.net将显示实际的服务器错误.

But if I do the submit without using Ajax then .net will show the actual server error.

关于如何显示错误的任何想法?因此，我的用户可以报告问题，而不仅仅是说内部服务器错误"

Any ideas on how I could perhaps get the error to show? So my users can report the problem instead of only being able to say 'internal server error'

谢谢

推荐答案

尽管我不建议向用户显示一个错误号以及实际的响应错误消息，但这是通过添加error回调

Although I wouldnt recommend showing the user an error number with the actual response error message this is how you can do this by adding the error callback

error: function(xhr,err){
    alert("readyState: "+xhr.readyState+"\nstatus: "+xhr.status);
    alert("responseText: "+xhr.responseText);
}

xhr 是XmlHttpRequest.

xhr is XmlHttpRequest.

readyState 的值为1:正在加载，2:已加载，3:互动，4:已完成.

readyState values are 1:loading, 2:loaded, 3:interactive, 4:complete.

状态是HTTP状态号，即404:未找到； 500:服务器错误； 200:确定.

status is the HTTP status number, i.e. 404: not found, 500: server error, 200: ok.

responseText 是服务器的响应-可以是Web服务中的文本或JSON，也可以是Web服务器中的HTML.

responseText is the response from the server - this could be text or JSON from the web service, or HTML from the web server.
