此远程脚本为什么会导致IE6挂起？

-1

请看看下面列出的html，让我知道为什么在加载远程脚本（位于'http://code.katzenbach.com/Default.aspx'）时IE6会冻结。该脚本返回JSONP并执行标题中列出的'callbackFunction'。当它正确运行时，您会看到弹出式警报显示数字1-500。这在FF3和IE7中正常工作。我无法理解为什么它在Internet Explorer 6中失败 - 处理器被挂钩并且一切都挂起。此远程脚本为什么会导致IE6挂起？

自己运行，让我知道你是否遇到同样的问题。我一整天都在盯着这个问题。谢谢你的帮助。

如果直接转到脚本（http://code.katzenbach.com/Default.aspx?callback=callbackFunction&test=true&c=500），您会看到未处理文件（未知的MIME类型）。这可能是由于您的服务器设置有问题。它似乎并不知道如何处理.aspx，而是试图流出文件。

回报是外部脚本是：

这是我最简单的测试来证明我遇到的问题。我实际上使用远程脚本来做其他事情。您会注意到，如果您将计数缩短到10，它可以工作（c = 10） – anschoewe 2008-10-08 22:44:47

请尝试实际回答问题，而不是挑选给出的示例！很显然，每个人都会发表一个简单的问题示例，以便人们更容易理解。 – nickf 2008-10-09 02:05:46

@nickf：我不想冒犯。没有 - 每个人都鄙视他们的代码并不明显。至少不是。 – roosteronacid 2008-10-09 10:04:12

我用Fiddler和IE6看了一下，看不到任何不寻常的东西（除了冻结浏览器的事实外）。

对http://code.katzenbach.com/Default.aspx?callback=callbackFunction&test=true&c=500的请求确实生成并返回2909字节。

我建议三件事情：

从您的内容类型分号之一：application/json;; charset=utf-8也许删除这两个分号和charset=utf-8完全（只是为了测试）
发送一个换行符在你完成后发送最后的)callbackFunction
更改为Content-Type: text/javascript，因为你真的在向浏览器返回Javascript，而其他内容类型可能会让IE6混淆（尽管不太可能）。

我在想1.是最有可能的。 IE6中可能存在一个解析错误，导致它在遇到两个分号时进入无限循环。因为否则就没有任何理由为什么你在做什么不应该工作。

尝试不同的MIME类型作为测试也是值得的。
