Standards information


Use the IHTMLMediaElement::currentTime property to retrieve the current playback position. For the total length of the audio or video clip, use IHTMLMediaElement::duration.

To invoke this event, do one of the following:

  • Play the video.
  • Move the position indicator on the playback controls.

Note  This event is fired approximately four times a second.


This example shows how to use the timeupdate event to track the elapsed time while a video plays.
