有没有办法从FBJS的画布中访问iframe的窗口对象？ （Facebook）的 [英] Is there a way to access an iframe's window object from the canvas in FBJS? (facebook)

问题描述

从Facebook画布中，我需要能够访问iframe窗口。通常情况下，您可以使用window.frames来执行此操作，但FJBS似乎不允许访问窗口对象。

From the facebook canvas, I need to be able to access an iframe window. Normally you could do this with window.frames, but FJBS doesn't seem to allow access to the window object.

有没有人知道如何访问窗口对象？ / p>

Has anyone figured out how to access window objects?

推荐答案

你可以尝试一下。让我知道它是如何工作的。

you could try this. Let me know how it works.

var myIframe = document.getElementById('myIframeId');

// could retrieve window or document depending on the browser
// (if FBJS allows it!?)
var myIframeWin = myIframe.contentWindow || myIframe.contentDocument;

if( !myIframeWin.document ) { //we've found the document
    myIframeWin = myIframeWin.getParentNode(); //FBJS version of parentNode
}
