如何将值从java脚本传递到嵌入的flex对象？
我试图弄清楚如何将字符串值（url）从 html 表单传递到嵌入的 Flex 对象。 到目前为止我发现的唯一方法是 http://livedocs.adobe.com/flex/3/html/help.html?content=passingarguments_5.html 在示例中，我使用的 Flex 函数“myFunc(s:String)”注册为“ExternalInterface”，稍后从 javascript 调用
--->mySwf.mxml:
<?xml version="1.0"?>
<!-- wrapper/AddCallbackExample.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="initApp()">
<mx:Script>
import flash.external.*;
import mx.controls.Alert;
public function initApp():void {
ExternalInterface.addCallback("myFlexFunction",myFunc);
}
public function myFunc(s:String):void {
Alert.show(s, 'Alert Box', mx.controls.Alert.OK);
}
</mx:Script>
<mx:Button id="myButton"
label="FLEX BUTTON"
click="Alert.show('FLEX LOADED!', 'Alert Box', mx.controls.Alert.OK);"/>
<mx:Label id="l1"/>
</mx:Application>
external.html
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<SCRIPT LANGUAGE="JavaScript">
function callApp() {
mySwf.myFlexFunction("show me something");
}
</SCRIPT>
<form id="f1">
<button onClick="callApp()">HTML BUTTON</button>
</form>

该方法似乎根本不起作用。如果我按下 Flex 按钮 - 我可以看到 Flex 弹出对话框。当我按下 HTML 按钮时，通过ExternalInterface 在 Flex 中调用 myFunc - 什么都没有
发生...我的代码中是否有任何错误提示？ 谢谢你，
I am trying to figure how to pass string value(url) from html form to embedded flex object.
the only method i found so far is "addCallback" method described in http://livedocs.adobe.com/flex/3/html/help.html?content=passingarguments_5.html
In the example i used flex function "myFunc(s:String)" is registered with "ExternalInterface" and called later from javascript
--->mySwf.mxml:
<?xml version="1.0"?>
<!-- wrapper/AddCallbackExample.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="initApp()">
<mx:Script>
import flash.external.*;
import mx.controls.Alert;
public function initApp():void {
ExternalInterface.addCallback("myFlexFunction",myFunc);
}
public function myFunc(s:String):void {
Alert.show(s, 'Alert Box', mx.controls.Alert.OK);
}
</mx:Script>
<mx:Button id="myButton"
label="FLEX BUTTON"
click="Alert.show('FLEX LOADED!', 'Alert Box', mx.controls.Alert.OK);"/>
<mx:Label id="l1"/>
</mx:Application>
external.html
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<SCRIPT LANGUAGE="JavaScript">
function callApp() {
mySwf.myFlexFunction("show me something");
}
</SCRIPT>
<form id="f1">
<button onClick="callApp()">HTML BUTTON</button>
</form>

The method doesn't seem to be working at all. If I push Flex button - i can see Flex popup dialog. When I push HTML button, calling myFunc in Flex via ExternalInterface - nothing
happens... Any pointers to errors in my code?
Thank you,

also you did not give an id to your object which is how the DOM identifies
