<!DOCTYPE html> <html> <body> <p>In this example, we use the HTML DOM to assign an "onratechange" event to a video element. The playbackRate property is used to change the playing speed of the video.</p> <video id="myVideo" width="320" height="240" autoplay controls> <source src="movie.mp4" type="video/mp4"> <source src="movie.ogg" type="video/ogg"> Your browser does not support the video tag. </video><br> <button onclick="setPlaySpeed()" type="button">Set video to be play in slow motion</button> <script> // Get the video element with id="myVideo" var x = document.getElementById("myVideo"); // Set the current playback speed of the video to 0.3 (slow motion) function setPlaySpeed() { x.playbackRate = 0.3; } // Assign an onratechange event to the video element, and execute a function if the playing speed of the video is changed x.onratechange = function() {myFunction()}; function myFunction() { alert("The playing speed of the video was changed"); } </script> </body> <!-- Mirrored from www.w3schools.com/jsref/tryit.asp?filename=tryjsref_onratechange_dom by HTTrack Website Copier/3.x [XR&CO'2014], Fri, 23 Jan 2015 08:30:20 GMT --> </html>
