blocks|key|849747|text|错误回调的签名为function(xmlHttpRequest,+textStatus,+exceptionThrown)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|849748|也许你看到的是错误的参数？|849749|entityMap^0|8|1H|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

The signature for the error callback is <code>function(xmlHttpRequest, textStatus, exceptionThrown)</code>.

Maybe you're looking at the wrong parameter?

blocks|key|843424|text|试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|843425|++++function+submitFormWithAjax(form)+{
++++form+=+$(form);
++++$.ajax({
++++++++url:+form.attr('action'),

++++++++type:+(form.attr('method')),
++++++++dataType:+'text',
++++++++error:+function(data)+{
++++++++++++$('#result').html(data);
++++++++},
++++++++success:+function(xmlHttpRequest,+textStatus,+exceptionThrown)+{
++++++++++++$('#result').html(xmlHttpRequest.statusText);
++++++++++++setTimeout("reloadPage()",+500);
++++++++}
++++});
++return+false;
}|code-block|syntax|javascript|843426|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Try this:

<pre><code> function submitFormWithAjax(form) {
 form = $(form);
 $.ajax({
 url: form.attr('action'),
 data: form.serialize(),
 type: (form.attr('method')),
 dataType: 'text',
 error: function(data) {
 $('#result').html(data);
 },
 success: function(xmlHttpRequest, textStatus, exceptionThrown) {
 $('#result').html(xmlHttpRequest.statusText);
 setTimeout("reloadPage()", 500);
 }
 });
 return false;
}
</code></pre>

blocks|key|843436|text|这一定与返回BadRequest+(错误400)有关。当返回代码是冲突的(错误409)时，似乎调用了错误回调。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|843437|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

It must be something about returning a BadRequest (error 400.) The error callback does seem to be called when the return code is Conflic (error 409).

blocks|key|843445|text|感谢大家的帮助。经过一些试验之后，我弄明白了，我所需要做的就是在jQuery中这样做|type|unstyled|depth|inlineStyleRanges|entityRanges|data|843446|++++error:+function(xhr,+textStatus,+exceptionThrown)+{
++++++++$('#result').html(xhr.responseText);
++++},|code-block|syntax|javascript|843447|这是控制器中的|843448|++++++++++++Response.StatusCode+=+(int)HttpStatusCode.BadRequest;
++++++++++++return+Content("There+was+an+error+in+your+request.");|843449|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Thanks for everyone's help. I figured it out after some trial, all I needed to do was this in jQuery

<pre><code> error: function(xhr, textStatus, exceptionThrown) {
 $('#result').html(xhr.responseText);
 },
</code></pre>

and this in the controller

<pre><code> Response.StatusCode = (int)HttpStatusCode.BadRequest;
 return Content("There was an error in your request.");
</code></pre>

I'm having some issues catching error messages from a controller via .ajax error. The script is called by a jQuery UI Dialog popup. Any help would be appreciated.

Here's the code snippet from my controller

<pre><code> Response.StatusCode = (int)HttpStatusCode.BadRequest;
 return Content("There was an error in your request.", MediaTypeNames.Text.Plain);
</code></pre>

and here's the jQuery script:

<pre><code>function submitFormWithAjax(form) {
 form = $(form);
 $.ajax({
 url: form.attr('action'),
 data: form.serialize(),
 type: (form.attr('method')),
 dataType: 'text',
 error: function(data) {
 $('#result').html(data);
 },
 success: function(data) {
 $('#result').html(data);
 setTimeout("reloadPage()", 500);
 }
 });
 return false;
}
</code></pre>

The <code>error: function(data)</code> isn't reading the returned error message. Any suggestions?
