call AS function from javascript/jquery
Using jquery,JS can we call a function in flex code.Below is that i have a button which calls a AS code.Can this be done if so how ?
<script>
function callas()
{
addBody();//call flex function
}
</script>
<input type="button" onclick="callas();" />
FLEX code
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" la开发者_JAVA技巧yout="absolute">
<mx:Script>
<![CDATA[
import mx.controls.Button;
import mx.controls.Alert;
import flash.display.InteractiveObject;
import flash.display.Sprite;
import flash.media.*;
import flash.net.*;
public function addBody():void
{
Alert.show("Got input from JS");
}
</mx:Script>
</mx:Application >
It should be something like this:
Javascript
function getFlashMovie(movieName) {
document.getElementById(movieName).setAttribute("name", movieName);
var isIE = navigator.appName.indexOf("Microsoft") != -1;
return (isIE) ? window[movieName] : document[movieName];
}
function callas()
{
// You need to know the ID of the object/embed tag; swfobject has an attribute for that. see http://code.google.com/p/swfobject/wiki/documentation#How_can_you_configure_your_Flash_content?
var swfobjectID = 'myFlashObjectID'
//call flex function
getFlashMovie(swfobjectID).addBody();
}
Actionscript / flex
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import mx.controls.Button;
import mx.controls.Alert;
import flash.display.InteractiveObject;
import flash.display.Sprite;
import flash.media.*;
import flash.net.*;
import flash.external.ExternalInterface;
// "javascript function", flash function
ExternalInterface.addCallback("addBody", addBody);
public function addBody():void
{
Alert.show("Got input from JS");
}
</mx:Script>
</mx:Application >

You need to utilize an Actionscript class named ExternalInterface
to interact with Javascript.
So, if you'd like to call a Javascript function from Flex or Flash, then you should use something like this:
ExternalInterface.call("Javscriptfunction", parameters);
Should you want to call Actionscript from Javascript, try the following:
ExternalInterface.addCallback("javascriptfunc", flexfunc);
protected function flexfunc(result:String):void{
trace(result);
}
