在Adobe AIR访问一个iframe的内容 [英] Accessing an iframe's contents in Adobe Air

问题描述

我一直有很多麻烦搞清楚如何，我可以在空气中的iframe中访问的​​内容。下面是一些例子jQuery的code，我一直在测试使用。

I have been having a lot of trouble figuring out how I can access the content within an iframe in Air. Here is some example jquery code that I have been testing with.

$(document).ready(function(){
    $("#frame").ready(function(){
    	air.trace($("#frame").contents().find("body").html());
    	air.trace(window.frames["frame"].innerHTML);
    	air.trace(document.getElementById("frame").innerHTML);
    });
});

我使用的是iframe的

The iframe I am using is.

<iframe src="http://google.com" id="frame" width="100%" sandboxRoot="http://google.com/" documentRoot="/" name="frame" height="600"></iframe>

从上面的code的输出为

The output from the above code is

null
undefined

正如你所看到的内容始终为null，未定义或空字符串。我缺少的东西是$ P $访问iframe的内容pventing我吗？任何建议，将不胜AP preciated。

As you can see the contents are always either null, undefined or an empty string. Am I missing something that is preventing me from accessing the content of the iframe? Any suggestions would be greatly appreciated.

解决的办法是这里<一个href="http://help.adobe.com/en_US/AIR/1.1/devappshtml/WS5b3ccc516d4fbf351e63e3d118666ade46-7f08.html" rel="nofollow">http://help.adobe.com/en_US/AIR/1.1/devappshtml/WS5b3ccc516d4fbf351e63e3d118666ade46-7f08.html

下面是我得到了它的工作的一个例子。

Here is an example of how I got it working.

<iframe src="http://google.com/local/iframe.html" id="frame" width="100%" sandboxRoot="http://google.com/local/" documentRoot="app:/" name="frame" height="600"></iframe>

从sandboxRoot请求任何（例如 http://google.com/local 的）将被从用于文档根目录，将被视为是从同一个域（google.com）。

Anything requested from the sandboxRoot(e.g. http://google.com/local) will be used from the document root and will be treated as if it is from the same domain(google.com).

在iframe.html我可以访问iframe来谷歌就好像它是来自同一个域。

In iframe.html I can access the iframe to google just as if it were from the same domain.

我知道必须有一个办法做到这一点：）

I knew there had to be a way to do this :)
