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

Solution 1:

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

Solution 2:

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);
....

Solution 3:

• 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).

Solution 4:

in your as

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

and in your html

<script>var super_var = 'something';

functionreturn_me_some_value() {
  return super_var;
}
</script>
