Change HTML background color with AS3

Question

Hi all,
I'm looking or a way to change my HTML background color trough Flash.
The problem is it's not working any ideas? here is the code i'm using
HTML HEAD
<script language="JavaScript">
function changeBgColor(newBgColor)
if (window.document && window.document.bgColor)
        document.bgColor = newBgColor;
</script>
Flash document
import flash.external.*;
var jsCall:String;
this.addEventListener(Event.ENTER_FRAME, bgChange)
function bgChange(e:Event):void{
    jsCall = String(ExternalInterface.call("changeBgColor", "#FF0000"));
best regards!!!

Answer 1

Change your AS3 function code to be more like...
function bgChange(e:Event):void{
    var result:Object = ExternalInterface.call("changeBgColor", "#FF0000");
and I suggest you do not use...
this.addEventListener(Event.ENTER_FRAME, bgChange)
as that will continuously trigger the function call at the frame rate of the Flash file.  If the intention is to only trigger it once, then just use...
bgChange();
