基本Flash问题-在电影结尾处调用JavaScript函数

Question

I'm a .net developer who somehow has ended up trying to get some Flash working - this is completely new to me, so please be patient!

I want to display a Flash video in a popup window, and when the video has finished playing, close the window using a javascript function "closeIt":

<script>
 function closeIt() {
  alert("About to close...");
  //code to close window here...
 }
</script>

How can I achieve this? I have imported a video into Flash (choosing "load external video with playback component"). This is in frame1. I thought that in the second frame I could make a call to ExternalInterface.call("closeIt") in the Actions window. I have tried this, but when I publish and view the flash movie in a web brower, I never see the javascript alert.

Can anyone help?

Answer 1

AS3, Option 1:

import flash.external.ExternalInterface;

(...)

ExternalInterface.call("closeIt()");

AS3, Option 2:

var request:URLRequest = new URLRequest("javascript:closeIt();");
navigateToURL(request, "_self");

You need the previously mentioned allowscript access for both methods, too:

<param name="allowscriptaccess" value="always" />

Answer 2

You can call JavaScript functions from flash.

First you would update your OBJECT/EMBED script in the host HTML page to include:

<param name="allowscriptaccess" value="always" />

Then from your code you can execute JavaScript method calls like:

getUrl('javascript:closeIt();');

Answer 3

Stick with AS3. You want to use the ExternalInterface class. Class Reference: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/external/ExternalInterface.html

Example Usage:

// import the package
import flash.external.ExternalInterface

// then launch that alert
ExternalInterface.call("closeIt");

Also I'd suggest you use firebug http://getfirebug.com to debug the JS part of it.
