  • 0

A have a flash widget (a music player) and there are about 10 instances of it on one page. I need to communicate between the flash and the javascript of the page it’s embedded in. I haven’t done much with actionscript for a long time, but some googling led me here, and to ExternalInterface. It seemed perfect, however there is one problem. I did something like this:

ExternalInterface.addCallback('stopTrack', this, stopTrack);

However, now stopTrack will be registered to 10 different things on the page. I want to be able to stop just one of the 10 tracks.

  1. I don’t ENTIRELY remember — but I seem to think that the callback isn’t added to the window object, but the swf object on the page — so somthing like

    document.getElementById('musicFlashPlayer10').stopTrack();

    would fire the callback on only that instance.

    This format might change between browsers – in any case, the callback is added to each javascript instance the flash file is loaded for.
