A Streaming Media JukeBox, Part IV: F-W Properties

F-R Section

The table below shows the control's properties that begins with the letters F through R. Let's demonstrate one of these properties. You can use the property playCount to determine or set the number of times to play the media. Let's take the jukebox from Column 53 and have it play every title a different number of times, equal to its relative position in the pull-down menu (beginning with one). We took the jukebox code from Column 53 and modify it. First, we added a generic setPlayCount() function that handles both browsers:

function setPlayCount(count) {
  if (activeX)
    document.mediaPlayer.playCount = count
  else
    document.mediaPlayer.SetPlayCount(count);
}

Then we modified the change() function to set the number of times the media is played:

function change() {
  var list = document.playerCtrl.streams;
  var streamURL = list.options[list.selectedIndex].value;
  document.mediaPlayer.Stop();
  document.displayMode.playOrPause.value = " Pause ";
  setFileName(streamURL);
  setPlayCount(list.selectedIndex + 1);
}

Notice the last line in the function above. It calls the generic setPlayCount() function with the relative position of the title in the pull-down list. You can now enjoy the show and play with the new version of the jukebox. The first title will play one time, the second title will play twice, and so on. Be patient between successive replays. It takes time to start buffering the media stream from the beginning. Here are the rest of the F-R properties:
