Introduction
The Video Ended Property in JavaScript is an essential aspect of handling video playback in web applications. It allows developers to determine whether a video has finished playing, enabling them to implement various functionalities such as automatically restarting the video, showing a message, or navigating to another section of the application when playback is complete. Understanding how to leverage the ended property is crucial for providing a seamless user experience.
The ended Property
The ended property is a read-only boolean property of the HTMLMediaElement interface. It indicates whether the media has finished playing. When the property is true, it means the video has ended; when it’s false, the video is still playing or has not started yet.
Data Type and Value
The ended property is of the boolean data type, which means it can take only two values:
| Value | Description |
|---|---|
| true | The video has finished playing. |
| false | The video is still playing or not yet started. |
Using the ended Property
To utilize the ended property, you can access it directly from a video element in the DOM. Below is the syntax for accessing the ended property:
let isVideoEnded = videoElement.ended;Example of Usage in Code
Here’s a simple example demonstrating how to use the ended property within an HTML page. In this example, we will alert the user when the video has finished playing:
<!DOCTYPE html>
<html>
<head>
<title>Video Ended Example</title>
</head>
<body>
<video id="myVideo" width="600" controls>
<source src="video.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<script>
let video = document.getElementById('myVideo');
video.addEventListener('ended', function() {
alert('The video has ended.');
});
</script>
</body>
</html>
<!DOCTYPE html>
<html>
<head>
<title>Video Ended Example</title>
</head>
<body>
<video id="myVideo" width="600" controls>
<source src="video.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<script>
let video = document.getElementById('myVideo');
video.addEventListener('ended', function() {
alert('The video has ended.');
});
</script>
</body>
</html>
This example creates a video player that alerts users once the video playback is complete. You can replace “video.mp4” with any video file available to you.
