Example
In the following example, the
playMP3() function is defined. The TextField object list_txt is
created and set so HTML text can be rendered. The text Track 1 and Track 2 are links inside
the text field. The
playMP3() function is called when the user clicks either link and plays the
MP3 that is passed as a parameter of the asfunction call.
var myMP3:Sound = new Sound();
function playMP3(mp3:String) {
myMP3.loadSound(mp3, true);
myMP3.onLoad = function(success) {
if (!success) {
// code to handle errors here
}
};
}
this.createTextField("list_txt", this.getNextHighestDepth(), 0, 0, 200,
100);
list_txt.autoSize = true;
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>";
When you click a link, the MP3 sound file streams in Flash Player.
