Question

在使用Google Chrome Frame的activeX对象时，我遇到了使postMessage（）工作的问题。这是我的情景：

我有一个父网页，由于我现在不会进入的原因，不安装了Google Chrome浏览器内嵌框架。为了使用GCF打开的外部页面，我需要通过在父页面中包含CFInstance.js文件来使用他们的activeX方法。我希望能够使用postMessage在父页面和子页面之间进行通信。

此处发布了一个示例：postMessage() with GCF

但是，我并没有完全遵循这个例子，因为它没有很好地解释如何使用ChromeFrame.postMessage（）。有没有人使用这种方法成功？

这是我的代码：

父页面：

非常感谢你的时间。另外，请原谅我在这篇文章中发现的任何明显的新手错误（代码相关或其他），这是我关于stackoverflow的第一个问题。
