获取iframe中的内容的高度，同时iframe中托管的外部网站，其code不能被访问 [英] Getting iframe content's height while iframe is hosting an EXTERNAL website whose code CAN'T be accessed

问题描述

可能重复：结果
  适合IFRAME对其内容的高度

由于在问题的标题描述。我正在寻找一种方式，根据我的IFRAME承载网站的高度来调整我的iframe的高度。因为我需要摆脱我的iframe的垂直滚动的。而在同一时间，我不希望设置一个非常巨大的静态高度我的iframe，因为这是不是很好，当我有小高地的页面。

As is described in the title of the question. I'm looking for a way to adjust the height of my iframe according to the height of the website that my iframe is hosting. Because I need to get rid of the vertical scroll of my iframe. And at the same time, I don't want to set a very huge static height to my iframe, as this is not nice when I have pages with small heights.

我发现有关我的问题很多解决方案，但解决不了我的问题：

I've found many solutions related to my problem, but can't solve my problem:

（*）更改iframe的高度，同时iframe中托管的内部网页很容易。你只需要添加下面的脚本到iframe onload事件：

(*) Changing the iframe's height while iframe is hosting an internal page is easy. You just add the following script to your iframe onload event:

        var frame = (document.getElementById) ? document.getElementById("YourFrameID") : document.all["YourFrameID"];
        var pageh = document.frames("YourFrameID").document.body.scrollHeight;
        frame.style.height = pageh + 'px';

但你会知道，当的src iframe的是具有iframe的外域。脚本崩溃并产生拒绝访问错误消息。

But as would you know, when the src of the iframe is outside the domain that has the iframe. the script crashes, and produces 'Access denied' error message.

（*）最后，我知道，如果我有机会到我的IFRAME承载的网页我的目标就可以实现。也许技术被称为跨域通信。

(*) Finally, I know that my goal can be achieved if I have access to the pages that my iframe is hosting. Perhaps the technique is called "Cross-Domain Communication".

不过，我的iframe的目标是接待来自外部网站的网页，并有向这些网站的访问权限。

HOWEVER, my iframe is aiming to host pages from EXTERNAL websites, and there is NO access to those websites.

这个问题已经被问了很多次。让我们通过提供一个最终的答案摆脱这个问题的：）

This question has been asked many times. Let's get rid of this issue by providing one final answer :)

或..让我们说，实现我的特定目标是不适用的。

Or.. let's say that achieving my specific goal is not applicable.

请注意，我用ASP.NET 4.0

谢谢，

推荐答案

这是根本不可能的，由于跨域安全方面的原因。

It is simply not possible due to the cross domain security reasons.
