处理当用户点击刷新Ajax错误 [英] handle ajax error when a user clicks refresh

问题描述

我道歉，如果这是我应该能够抬起头来。所有我想是这样超负荷的条款。

i apologise if this is something i should be able to look up. all of the terms i wanted were way overloaded..

下面是我的问题：当我打开一个网页，它触发了整个系列的Ajax调用。如果我再preSS Shift +刷新，所有这些Ajax调用正在考虑的错误，并显示整个页面本身重新加载之前他们错误信息的对话框。

here is my problem: when i open a page, it fires off a whole series of ajax calls. if i then press Shift+Refresh, all of those ajax calls are being considered errors, and showing their error message dialogs before the entire page itself reloads.

因此​​错误是由客户端引发的 - 有反正我可以找出如果是这样我就可以忽略它了呢？例如，在xmlhtt prequest，或在AJAX功能（我使用jQuery的BTW）

so the error is being triggered by the client - is there anyway i can find out if this is the case so i can ignore it? eg in the xmlhttprequest, or in the ajax function (i am using jquery btw)

jQuery的引发错误事件在用户离开页面或者通过令人耳目一新，点击一个链接，或改变浏览器的URL。您可以通过检测这些类型的错误通过实现Ajax调用错误处理程序，并检查xmlHtt prequest对象：

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:

$.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
});
