jQuery ajax post 返回 501 错误代码

我们正在使用 jQuery(1.2.3) ajax post，并且偶尔会收到 12031/501 错误消息。

这个错误的原因可能是什么？

示例代码


jQuery.post('${pageContext.request.contextPath}/sample/someAction.do', jQuery("#form_name").serialize(), function(status){
      //Some other code for checking the status......
}

表单有两个文本区域（一个禁用，一个启用）和一个复选框。还有一个提交按钮。

并且有一个ajax错误处理函数，用于处理12031/501类型的错误消息。有时会显示一个警告框，指出 ajax post 中发生错误。


$("#form_name").ajaxError(function(event, xhr, settings, exception) {
 var errorMessage = "Error in ajax post -";
 errorMessage += "\n\t url: " + settings.url;
 errorMessage += "\n\t exception: " + exception + ((exception) ? " - " + exception.description : "");
 errorMessage += "\n\t readyState: " + xhr.readyState;
 errorMessage += "\n\t status: " + xhr.status;
 errorMessage += "\n\t statusText: " + xhr.statusText;
 errorMessage += "\n\t responseText: " + xhr.responseText;
 errorMessage += "\n\t";
 alert('Error occured in ajax post..........'+errorMessage);
 });

仅当 ajax post 出现错误且错误代码为 12031（与服务器的连接已重置。）或 501/12152 时，才会显示此警告框。

现在我们可以看到另外一个错误代码是 12152（服务器返回了无效或无法识别的响应。）。

这是 jQuery(1.2) 问题还是环境中的其他问题还是 IE7？

如果我们重新提交请求，那么它就可以正常工作。现在我们告诉用户重新提交请求以便保存数据。

现在这不是一个可行的解决方案。而且这个问题偶尔会出现。

任何有关这些错误代码的见解将不胜感激。

谢谢

We are using jQuery(1.2.3) ajax post and we are getting 12031/501 error message sporadically.

What could be the reason of this error?

Sample code


jQuery.post('${pageContext.request.contextPath}/sample/someAction.do', jQuery("#form_name").serialize(), function(status){
      //Some other code for checking the status......
}

Form has two textarea(one disabled, one enabled) and a check box. And a submit button.

And there is one ajax error handling function which is for handling 12031/501 kind of error msg. Which sometimes shows a alert box saying that error happen in ajax post.


$("#form_name").ajaxError(function(event, xhr, settings, exception) {
 var errorMessage = "Error in ajax post -";
 errorMessage += "\n\t url: " + settings.url;
 errorMessage += "\n\t exception: " + exception + ((exception) ? " - " + exception.description : "");
 errorMessage += "\n\t readyState: " + xhr.readyState;
 errorMessage += "\n\t status: " + xhr.status;
 errorMessage += "\n\t statusText: " + xhr.statusText;
 errorMessage += "\n\t responseText: " + xhr.responseText;
 errorMessage += "\n\t";
 alert('Error occured in ajax post..........'+errorMessage);
 });

This alert box will display only when there is error on ajax post and the error code is 12031(The connection with the server was reset.) or 501/12152.

Now there is one more error code we are able to see is 12152(The server returned an invalid or unrecognized response.).

Is this a jQuery(1.2) issue or something else in environment or is it IE7?

If we resubmit the request then it is working fine. For now we are telling user to resubmit the request so that data can be saved.

Now this is not a viable solution. And this problem occurs sporadically.

Any insight on those error codes would really be appreciated.

Thanks
