這是我父母iframe通信的測試實現的簡化代碼。我添加了一些樣本如何使用。但我必須指出，它已經超出了我的實驗室部分，而且我目前還沒有時間來檢查它是否完全跨瀏覽器兼容。但如果不是，那麼只會做一些小的改變。 （編輯在當前鉻，ff和IE 6-9測試）
我希望這會幫助你與你的問題。但是，我現在不能保證它能夠完美地工作（但我很確定）。

call a function on the helper object, this is the savest way for the commincation because

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)

如果iframe和父域相匹配，你可以在兩者之間進行通信的。這就是TinyMCE和CKEditor等編輯器的工作原理。 js對象可以在兩者之間傳遞，但是由於內存泄漏和其他問題，您需要小心使用dom對象。如果你使用類似jQuery的庫，它也可以工作，但前提是上下文是正確的文檔。 – 2013-04-08 17:24:16
附加說明。你不能得到可拖動的工作，從文檔到iframe。這是可能的，但它需要一些事件從iframe傳遞到文檔以及其他方式，以及一些額外的自定義。但通常是可能的。我有這樣的工作。但因爲這只是一個測試，我不知道我是否仍然擁有它。 – 2013-04-08 17:35:36
感謝您的洞察力。如果你覺得它並且想分享代碼，我會很樂意接受它作爲一個回報，讓其他人看到相同的利益。 – Brian 2013-04-08 17:37:53
