在IE7 jQuery的AJAX的问题（可能还有其他版本一样） [英] jQuery AJAX problem in IE7 (possibly other versions as well)

问题描述

谁能开导我，为什么下面的code将无法在IE7中工作，但它工作得很好，在Chrome / Firefox的？

  $（文件）。就绪（函数（）{
  $阿贾克斯（{
    键入：POST，
    数据类型：文本，
    缓存：假的，
    网址：/ajax/ajax.asp
    数据：CMD = check_forfeits
    成功：函数（MSG）{
      返回false;
    }
  }）;
}）;
 

的JavaScript错误IE抛出的权限被拒绝

如果我删除了code该位从JS文件的页面有问题的网页工作得很好，没有任何错误，所以错误就在于code表示有点相信。

::: UPDATE :::

别的东西，是有一点奇怪的是，当我刷新页面（在IE7）我没有得到任何JavaScript错误，这code似乎正常工作。所以，就好像第一次页面加载此code段错误，但在那之后它运行得很好。

解决方案

我碰到了同样的问题。

我身边做了工作，解决问题。我写的code键使Ajax调用，而不使用jQuery（创建XMLHttpObject，onreadystatechange的，等等）。然后我用jQuery来解析XML。

由于某些原因，jQuery的AJAX不会与IE7的正常工作。

您并没有真正得到一个错误，在IE7，但如果你再调试它，你会看到，服务器永远不会击中或code永远不会到达成功的块。

Can anyone enlighten me as to why the following code won't work in IE7 but it works just fine in Chrome/Firefox?

$(document).ready(function(){
  $.ajax({
    type: "POST",
    dataType: "text",
    cache: false,
    url: "/ajax/ajax.asp",
    data: "cmd=check_forfeits",
    success: function(msg) {
      return false;
    }
  });
});

The javascript error IE throws out is 'Permission Denied'

If I remove that bit of code from the JS file for the page in question the page works just fine, no errors, so the error lies in that bit of code I believe.

:::UPDATE:::

Something else that is a little strange is that when I refresh the page (in IE7) I get no javascript errors and this code seems to work correctly. So it's as if the first time the page loads this code snippet errors but after that it runs just fine.

解决方案

I ran into the same issue.

I did a work around to resolve the issue. I wrote the code to make the ajax call without using jQuery (created XMLHttpObject, onreadystatechange, etc). Then I used jQuery to parse the XML.

For some reason the jQuery's ajax doesn't work well with IE7.

You don't really get an error in IE7 but if you debug it then you'll see that the server is never hit and or code never reaches the success block.
