Example

The following JavaScript example shows how to retrieve the Attributes property of a MediaElement that has a Source property set to an ASX playlist file. The retrieved MediaAttributeCollection is iterated through, and the Name and Value properties of each MediaAttribute are displayed.

function onMediaOpened(sender, args) {
    // Variable to hold the MediaAttribute.
    var attribute;
   
    // Get the MediaAttribute named Title.
    try
    {
        var attributesCollection = sender.Attributes;
        attribute = attributesCollection.getItemByName("Title");
    }
    catch(errorObj)
    {
        alert(errorObj.message);
    }
    
    // Display the Value of the MediaAttribute.
    if(attribute != null)
    {
      alert("The title of the track is: " + attribute.value);
    }
}
