Player.CurrentPlaylistChange event

[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The CurrentPlaylistChange event occurs when something changes within the current playlist.

Syntax

Player.CurrentPlaylistChange(
  change
)

Parameters

change

Number (long) indicating what type of change occurred to the playlist. See the Player.PlaylistChange event for a table of possible values.

Return value

This event does not return a value.

Remarks

This event does not occur when a different playlist becomes the current playlist. It only occurs when a change happens within the current playlist, such as a media item being appended to the playlist.

The value of event parameters is specified by Windows Media Player, and can be accessed or passed to a method in an imported JScript file using the parameter name given. This parameter name must be typed exactly as shown, including capitalization.

Examples

The following JScript example updates the text in an HTML DIV element, named PlItems, to display the names of the media items in the current playlist. The Player object was created with ID = "Player".

<!-- Create an event handler for current playlist change. -->
<SCRIPT FOR = "Player" EVENT = "currentPlaylistChange(change)">
   switch (change){
      // Only update for move, delete, insert, and append events.
      case 3, 4, 5, 6:

         // Clear the contents of the DIV.
         PlItems.innerHTML = "";

         // Loop through the playlist and display each item name.
         for (var i = 0; i < Player.currentPlaylist.count; i++){
            PlItems.innerHTML += Player.currentPlaylist.item(i).name;
            PlItems.innerHTML += "<br>";
         }
         break;
      
      default:
   } 
</SCRIPT>
