在使用（得多）与异步Ajax调用IE7挂起：假的 [英] IE7 hangs when using (to much) ajax calls with async: false

问题描述

我有下面的函数在一个更大的脚本加载的翻译从一个PHP文件：

I have the following function in a much larger script that loads translations from a php file:

function loadLanguages(language){
 var data = new Object();
 data.language = language;
 var dataString = $.toJSON(data);
 var langSt = $.ajax({
  url: "/VID/ajax/loadtranslations.php",
  data: ({data: dataString}),
  async: false
 }).responseText;
 var languageArr = $.evalJSON(langSt);
 return languageArr;
}

工作在FF，但在IE7和IE8浏览器将挂起。当我注释掉功能IE不挂Ajax调用。如果我将它设置为异步：真正的功能不工作了，但浏览器不会挂起。只有当我设置异步为false，IE会挂起。我有点疑惑，为什么！

Works in FF, but in IE7 and IE8 the browser will hang.. When I comment out the ajax call in the function IE doesn't hang. If I set it to async: true the function doesn't work anymore, but the browsers will not hang. Only if I set async to false, IE will hang. I'm a bit puzzled why!

推荐答案

您应该使用异步：假;它将总是挂起浏览器直到请求完成

You should never use async: false; it will always hang the browser until the request finishes.

这是一个事实的必然结果JavaScript是单线程的，而且永远不会改变。

This is a necessary consequence of the fact that Javascript is single-threaded, and will never change.
