flash button link using actionscript 2.0

Look down in your Properties panel. If it's showing the following

Player: 9, Actionscript 3.0

then use your same script

my_button.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(event:MouseEvent):void{
navigateToURL(new URLRequest(" http://www.mywebsite.com"));
}

If you want to change to Actionscript 2.0, click on the Settings button in the Properties panel and change the Actionscript version under the Flash tab.
Then you can use getURL

my_button.onRelease = function(){
getURL(" http://www.mywebsite.com");
}

Usual disclaimer; I know nothing about Flash, but maybe it'll still work

Adobe is definately paranoid... I can't write l-o-c-a-t-i-o-n in a post... so just remove the "-" in l-o-c-a-t-i-o-n below


In HTML:
<script type="text/javascript">
function setLocation(url){
document.l-o-c-a-t-i-o-n.href=url;
}
</script>

From what I read you need to allow script access explicitly for this to work.
<param name="allowScriptAccess" value="always" />

In AS:
import flash.external.*;
ExternalInterface.call("setLocation"," http://www.google.com");

oh, but i tried using getURL and that doesn't work. Is there another way using actionscript 2.0?

Thats AS3 code you're using there, so you need to change your Publish Settings to Actionscript 3.0.
Or you could just leave your settings as is and go back to using good old getURL.
