在flex組件中嵌入html代碼，可以利用flex iframe。這個在很多時候會用到的，有時候flex必須得這樣做，如果你不這樣做還真不行……
flex而且可以和html進(jìn)行JavaScript交互操作，flex調(diào)用到html中的JavaScript方法以及獲取調(diào)用后的返回值。

復(fù)制代碼 代碼如下:

// 調(diào)用當(dāng)前iframe嵌入頁面中的sayHello 的JavaScript方法
iFrameBySource.callIFrameFunction("sayHello");
}
protected function sayHandler(event:MouseEvent):void {
// 調(diào)用當(dāng)前iframe嵌入頁面中的say的JavaScript方法，并傳入一個參數(shù)
iFrameBySource.callIFrameFunction("say", ["hello world!"]);
}
protected function sayHiHandler(event:MouseEvent):void {
// 調(diào)用當(dāng)前iframe嵌入頁面中的sayHi的JavaScript方法，并傳入2個參數(shù)。sayHi方法會返回一個字符串，最后一個回調(diào)就是輸出值的函數(shù)
iFrameBySource.callIFrameFunction("sayHi", ["hello world", "李四"], function (data:*): void {
Alert.show(data);
