There is an undefined error due to Ajax request in jQuery. But it works locally. Error referencing in jquery1.3.2.js @ 3633 line
由于 jQuery 中的 Ajax 请求，存在未定义错误。但它在本地工作。在 jquery1.3.2.js @ 3633 行中引用错误
xhr.send(s.data);
My code is:
我的代码是：
$.ajax({
type: "POST",
url: 'index.php',
data: "action=showpath&type=images&path=&default=1",
cache: false,
dataType: "html",
success: function (data) {
$('#addr').html(data);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
}
});
alerts in code shows me (0, 'undefined');
代码中的警报显示给我 (0, 'undefined');

This could be happening if your ajax request is getting canceled before it completes. jQuery throws the error event when the user navigates away from the page either by refreshing, clicking a link, or changing the URL in the browser. You can detect these types of errors by by implementing an error handler for the ajax call, and inspecting the xmlHttpRequest object:
如果您的 ajax 请求在完成之前被取消，则可能会发生这种情况。当用户通过刷新、单击链接或更改浏览器中的 URL 离开页面时，jQuery 会抛出错误事件。您可以通过为 ajax 调用实现错误处理程序并检查 xmlHttpRequest 对象来检测这些类型的错误：
$.ajax({
/* ajax options omitted */
error: function (xmlHttpRequest, textStatus, errorThrown) {
if(xmlHttpRequest.readyState == 0 || xmlHttpRequest.status == 0)
return; // it's not really an error
else
// Do normal error handling
});

Couldn't tell ya offhand, but it is probably something on the server-side in index.php. Best way to tell is to look at the raw response using a http debugger. The Firebugfirefox extension has a pretty good one, and fidder2is a beefy option.
无法直接告诉你，但它可能是 index.php 中服务器端的东西。最好的判断方法是使用 http 调试器查看原始响应。在Firebug的Firefox扩展有着相当不错的一个，并且fidder2是一个结实的选择。
