这是我的父 iframe 通信测试实现的简化代码。我添加了一些示例如何使用它。但我必须注意它不在我的实验室部分，我目前没有时间检查它是否完全跨浏览器兼容。但如果不是，则只需要做一些小的更改。 （EDIT在当前的 chrome、ff 和 IE 6-9 中测试）
我希望这能帮助您解决问题。但是我现在不能保证它会完美运行（但我很确定）。

call a function on the helper object, this is the savest way for the commincation because
there is it minimizes the risk to mix the differnt context

/*
This way would work at least in chrome, with the current version with jquery, but it relays the jQuery implementation
that the correct document is used.
*/

/*
One thing you should NEVER do is the following:
iframe.$(".info-from-parent").append( $("<div></div>") );
The reason you should not do this is because this mixes DOMElements of different context.
This will result in unexpected crashes/bahaviors in some browsers (but could work in others, or at least it will look like it would work)
