calling a Flash ExternalInterface with JavaScript

I'm trying to call a function declared with ExternalInterface in a Flash swf, using JavaScript. It worked once, but all of a sudden, it stopped working.

I have a debug version of the Flash Player, but no errors occur in Flash. Not even a "Security Sandbox Error" or something. The only error I get is the following error in JavaScript Error: Error in Actionscript. Use a try/catch block to find error.

I'm using AS3, exporting for Flash Player 10 and testing on Firefox 3/Safari 4, on a Mac.

Any assistance would be greatly appreciated.

Check out ExternalInterface.marshallExceptions. It should allow you to see more details about the error.

in your as

import flash.external.*;
ExternalInterface.call("return_me_some_value()");

and in your html

<script>
var super_var = 'something';

function return_me_some_value() {
  return super_var;
}
</script>

  • Make sure the javascript and the SWF are on the same domains otherwise use a crossdomain.xml
  • Make sure you have added the allowScriptAccess parameter to the flash embed
  • If you run it locally you may (but don't think it will change anything) add the location to flash players trusted ones (in the security panel).

Kinda tricky to help you solve something that 'worked once'. But using ExternalInterface is pretty straightforward -- here's what I do:

in AS3: something like

...
if (ExternalInterface.available) ExternalInterface.addCallback("search", jsSearch);
...
private function jsSearch(term:String):void 
{
    new Search(data);
}

in JS: something like

...
var term = $('input#search').val();
$("#swfobject").get(0).search(term);
....
