在使用 Google Chrome Frame 的 activeX 对象时,我在让 postMessage() 工作时遇到问题。这是我的场景:
我有一个父页面,由于我现在不会进入的原因,无法安装Google Chrome Frame。为了打开使用 GCF 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对话。
此处发布了一个示例:带有 GCF 的 postMessage()
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过?
这是我的代码:
父页面:

});
document.body.appendChild(gcf);
if (window.attachEvent) {
window.attachEvent('onmessage', message);
}
function message(event) {
var messageParams = $.parseJSON(event.data);
alert(messageParams);
}

非常感谢您的宝贵时间。另外,请原谅我在这篇文章中可能犯的任何明显的新手错误(代码相关或其他),这是我在 stackoverflow 上的第一个问题。
