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

问题描述

如果这是我应该能够查找的内容，我深表歉意.我想要的所有术语都超载了..

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

这是我的问题:当我打开一个页面时，它会触发一系列的 ajax 调用.如果我然后按 Shift+Refresh，所有这些 ajax 调用都被视为错误，并在整个页面本身重新加载之前显示它们的错误消息对话框.

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.

所以错误是由客户端触发的 - 无论如何我可以找出是否是这种情况所以我可以忽略它吗?例如在 xmlhttprequest 或 ajax 函数中(我使用 jquery 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)

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:

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
});
