MDN wants to learn about developers like you:


The GlobalEventHandlers.onplay property sets and returns the event handler for the play event that is fired when playback has begun.

Syntax :

element.onplay = handlerFunction;
var handlerFunction = element.onplay;

handlerFunction should be either null or a JavaScript function specifying the handler for the event.

Example :

<!DOCTYPE html>

<title>onplay event example :</title>

<p>This example demonstrates how to assign an "onplay" event to a video element.</p>

<video controls onplay="myFunction()">
  <source src="mov_bbb.mp4" type="video/mp4">
  <source src="mov_bbb.ogg" type="video/ogg">
  Your browser does not support HTML5 video.

function myFunction() {
    alert("The video has started to play");
