Execute a script when the length of the media changes in HTML?

The ondurationchange attribute triggers when the length of the audio/ video changes in HTML.

Example

You can try to run the following code to implement ondurationchange attribute −

<!DOCTYPE HTML>
<html>
   <body>
      <video width = "300" height = "200" controls ondurationchange = "display(this)">
         <source src = "/html5/foo.ogg" type = "video/ogg" />
         <source src = "/html5/foo.mp4" type = "video/mp4" />
         Your browser does not support the video element.
      </video>
      <script>
         function display(vLength) {
            alert("Video Length: " + vLength.duration + " seconds");
         }
      </script>
   </body>
</html>
