Execute a script when the file is unavailable in HTML?

Use the onemptied attribute in HTML to execute a script when the file is unavailable in HTML or it is empty.

Example

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

<!DOCTYPE HTML>
<html>
   <body>
      <video width = "300" height = "200" controls onemptied ="display()">
         <source src = "/html5/foo.ogg" type = "video/ogg" />
         Your browser does not support the video element.
      </video>
      <script>
         function display()
         {
            alert ("Sorry! Empty playlist!");
         }
      </script>
   </body>
</html>
