HTMLtext linking to actionscript functions

AS3
You can do it with a link event:

html text would be:

<a href='event:moveUp'>UP</a>

listener on the field:

myHTML.addEventListener(TextEvent.LINK, linkHandler);

function linkHandler(event:TextEvent):void
{
trace(event.text); // traces 'moveUp'
}

See this page if that’s not enough:

In as2 it was a bit different, see below:

AS2:
You can use htmlText to call AS functions. Can put CSS rollover styles and things on too for some lazy-ok-looking action.

list_txt.html = true;
list_txt.multiline = true;
list_txt.htmlText = "<a href=\"asfunction:playMP3, track1.mp3\">Track 1</a><br>";
list_txt.htmlText += "<a href=\"asfunction:playMP3, track2.mp3\">Track 2</a><br>";
