A working ExternalInterface.call sample?

[Livi17]

Can someone create a working ExternalInterface.call example?

Just a simple alert function call, with the javascript function on the html page?

I've been searching for 2 days, and even samples that people have posted on blog tutorials are not working.

This sample does not even work:
http://livedocs.adobe.com/flash/9.0/...=00001655.html


Is it no longer supported?

[Livi17]

This does not work:

Within the HTML Head tags:

<script type="text/javascript">
function show_alert()
{
alert("I am an alert box!");
}
</script>

In the fla:

import flash.external.*;
externalinterface.call("show_alert");

This should immediately trigger a javascript alert box when the page is loaded.

Are you doing your testing offline/online?

online

[Livi17]

setTimeout(function(){ExternalInterface.call("show_alert"");}, 1000);

This worked... delaying the call for a brief moment.

Glad you found a workaround.

Still Curious,

1.) Was this happening in all browsers?
2.) PC / OS X (or both?)
3.) What version of Flash Player?

the ExternalInterface doesn't work very well with IE because of a bug (in IE)
google 'as2 externalinterface ie bug' for more information but be advised the info is all scaterred and there's no official fix for this bug.

more so, theres many kinds of fixes according to many uses you can give the externallinterface. theres a fix to use the EI in a <form> tag, outside the form tag, in an invisible flash object, etc...

one of the fixes is that delay

another fix is to use swfobject2, but that brings up more bugs and fixes.

it's a nightmare, and it makes me want to upgrade to AS3

The same held true with FireFox, also with certain issues, not sure if the issues still remain a problem however. Fun, fun.

The problem was happening on both PC and OS X.
IE, Firefox and Safari.

This fix worked on all.

I am using SWFObject as well.

Flash 10.0 r22


I think the issue was timing of events more than anything. I was using the ExternalInterface.Call on the first frame of the movie... so it was likely being called before the browser had loaded and gone through the entire external javascript file.

Did you try to use full path? flash.external.ExternalInterface and take a look that you'r using the function name in lower case, i dont know if as2 its case sensitive, but.. cya

PD: I'm just post this because today i was having this issue in as2, yeah! people still using as2! and if someone have this issue hope this help him!
