MXML:

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*"

creationComplete="onCreationComplete()">

<mx:Script source="ExternalInterfaceJSAS.as" />

<mx:Canvas width="100%" height="100%">

<mx:Panel x="0" y="0" height="300" width="500" title="ExternalInterface : JavaScript to Flash">

<mx:Canvas height="100%" width="100%">

<mx:TextArea x="8" y="9" width="464" height="250" id="tArea"/>

</mx:Canvas>

</mx:Panel>

</mx:Canvas>

</mx:Application>

ExternalInterfaceJSAS.as:

import flash.events.MouseEvent;

import flash.external.ExternalInterface;

import flash.system.Security;

private function onCreationComplete():void

{

Security.allowDomain("*");

submitButton.addEventListener("click", onSubmitClick);

}

private function onSubmitClick(event:MouseEvent):void

{

//we need to make sure that ExternalInterface is available

//If you are running in StandAlone player, then this will return false

if(ExternalInterface.available)

{

var s:String = tInput.text;

//call the javascript function

ExternalInterface.call("displayString", s);

}

HTML:

<html>

<head>

<title>ExternalInterfaceJSAS</title>

<style>

body { margin: 0px;

overflow:hidden }

</style>

//called when send button is pressed

function doSubmit()

{

//get the data from the TextArea

var ta = document.getElementById("outputField");

sendToFlash(ta.value);

}

function sendToFlash(input)

{

//get access to the flash player in the page with an ID of fp

var flash = (navigator.appName.indexOf ("Microsoft") !=-1)?window["fp"]:document["fp"];

//call the function in flash

flash.displayString(input);

}

</script>

</head>

<object id='fp'

classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000'

codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,5,0,0'

height='300' width='450'>

<embed name='fp'

pluginspage='http://www.macromedia.com/go/getflashplayer'

allowScriptAccess='always'

src='ExternalInterfaceJSAS.swf' height='300'

width='500' />

</object>

<form>

<br />

</form>

</body>

</html>

需要注意的地方是不能直接打开html，需要放在服务器上运行，如Tomcat上
