Topic: Thumbnail caption on rollover - here's how

Here is a great way to get hovering captions on thumbnail rollover:

in thumb.as, add the following as the first line in the onRollover function:

   getURL("javascript:thumb_hoverChange('" + XMLManager.getInstance().imageCaptions[mIndex] + "');")


then add the following as the first line in the onRollOut function:

   getURL("javascript:thumb_hoverChange('');")


Now, in your HTML page add the following javascript function:

        function thumb_hoverChange(hovertext){            
            document.getElementById("viewer").title = hovertext;
        }

where "viewer" is the id of your flash viewer object.

As cool as this is, I would like to use the ExternalInterface.call method to do this but I can't get it to work in thumb.as.  I import flash.external.ExternalInterface but I still get the error:

There is no method with the name 'ExternalInterface'

Can anyone tell me how to get this to work?

Re: Thumbnail caption on rollover - here's how

well I can't help much except to say that it uses actionscript 2 which does not support getURL.  I think you have to use ExternalInterface but I have not got that working either.
