我正在嘗試使用Ben Almans jquery postmessage來調整iFrame的大小。我或多或少地用不同的服務器和動態內容作爲例子。jquery postmessage不一致性
我已經發布了一個問題到該網站，但它可能是一個太新手問題，實際上回答。
我已經得到它的工作發送郵件作爲跨域，但調整大小隻是沒有工作。我只是重新發布我發佈爲Toby的內容：
我無法讓iFrame在瀏覽器中持續調整大小。這是你遇到過的嗎？我添加了一個時間戳來知道每個函數何時被調用，並且它很奇怪...：
- Firefox工作正常 - childpage在父頁面之前運行。
- Chrome 7將展開，而不是收縮。時間戳=父代之前的子代
- IE 8 ...父代在子代之前運行...！並且每個鏈接上的iframe增加30次。
任何有這方面的經驗嗎？
添加我的代碼參考兩頁：
