how to pass value from java script to embedded flex object?
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" metho开发者_开发问答d 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>
<OBJECT CLASSID="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
WIDTH="850"
HEIGHT="610"
CODEBASE="http://active.macromedia.com/flash5/cabs/swflash.cab#version=5,0,0,0">
<EMBED SRC="mySwf.swf"

</OBJECT>
</html>
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,Try this in case you aren't using the right browser:
<SCRIPT LANGUAGE="JavaScript">
// This function returns the appropriate reference,
// depending on the browser.
function getFlexApp(appName)
{
if (navigator.appName.indexOf ("Microsoft") !=-1)
{
return window[appName];
}
else
{
return document[appName];
}
}
function callApp() {
getFlexApp('mySwf').myFunc("show me something");
}
</SCRIPT>
also you did not give an id to your object which is how the DOM identifies
<OBJECT id='mySwf' CLASSID="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
try this:
ExternalInterface.addCallback("myFunc",myFunc);
加载中,请稍侯......
