HTML Audio loop
Property: Mastering Audio Looping
The loop
property in HTML’s <audio>
element is a boolean attribute that specifies whether the audio should start over again when it reaches the end. This is particularly useful for background music, sound effects, or any scenario where continuous playback is desired. This guide provides an in-depth look at the loop
property, including its syntax, usage, and practical examples.
What is the loop
Property?
The loop
property, when set, ensures that the audio restarts from the beginning once it finishes playing. It is a straightforward yet powerful attribute that enhances user experience by providing continuous audio playback without manual intervention.
Purpose of the loop
Property
The primary purpose of the loop
property is to enable continuous and automatic playback of an audio file. This is beneficial in scenarios where uninterrupted audio is needed, such as:
- Background music on a website
- Repeating sound effects in a game
- Looping audio samples in a music application
Syntax and Usage
The loop
property can be set directly in the HTML <audio>
tag or manipulated dynamically using JavaScript.
HTML Syntax
To enable looping, simply add the loop
attribute to the <audio>
element:
<audio controls loop>
<source src="audio.mp3" type="audio/mpeg" />
Your browser does not support the audio element.
</audio>
JavaScript Syntax
You can also control the loop
property using JavaScript:
const audio = document.getElementById("myAudio");
audio.loop = true; // Enable looping
audio.loop = false; // Disable looping
Important Attributes and Methods
Attribute/Method | Type | Description |
---|---|---|
`loop` | Boolean | Specifies whether the audio should loop. Set to `true` to enable looping and `false` to disable it. |
`audio.loop = true` | JavaScript | Enables looping using JavaScript. |
`audio.loop = false` | JavaScript | Disables looping using JavaScript. |
Note: When the loop
attribute is present, the audio will continue to play indefinitely until explicitly stopped or the attribute is removed. â ī¸
Practical Examples
Let’s explore some practical examples demonstrating the use of the loop
property in both HTML and JavaScript.
Example 1: Basic Audio Looping with HTML
This example shows how to enable audio looping directly in the HTML:
<audio controls loop>
<source src="https://www.w3schools.com/tags/horse.ogg" type="audio/ogg" />
Your browser does not support the audio element.
</audio>
In this example, the audio file will loop continuously. đ´
Example 2: Controlling Audio Looping with JavaScript
This example demonstrates how to control the loop
property using JavaScript:
<audio id="myAudioJS" controls>
<source src="https://www.w3schools.com/tags/horse.ogg" type="audio/ogg" />
Your browser does not support the audio element.
</audio>
<button onclick="toggleLoop()">Toggle Loop</button>
<script>
const audioJS = document.getElementById("myAudioJS");
function toggleLoop() {
audioJS.loop = !audioJS.loop;
alert("Looping is now: " + (audioJS.loop ? "Enabled" : "Disabled"));
}
</script>
Clicking the “Toggle Loop” button will enable or disable the looping of the audio. đ
Example 3: Dynamically Setting Audio Looping on Page Load
This example shows how to set the loop
property dynamically when the page loads:
<audio id="myAudioLoad" controls>
<source src="https://www.w3schools.com/tags/horse.ogg" type="audio/ogg" />
Your browser does not support the audio element.
</audio>
<script>
const audioLoad = document.getElementById("myAudioLoad");
window.onload = function () {
audioLoad.loop = true; // Enable looping on page load
};
</script>
In this case, the audio will automatically loop when the page is loaded. đĩ
Example 4: Creating a Looping Background Music Player
This example showcases a looping background music player with play/pause controls:
<audio id="backgroundMusic" loop>
<source src="https://www.w3schools.com/tags/horse.ogg" type="audio/ogg" />
Your browser does not support the audio element.
</audio>
<button id="playPauseBtn" onclick="togglePlay()">Play/Pause</button>
<script>
const backgroundMusicAudio = document.getElementById("backgroundMusic");
const playPauseButton = document.getElementById("playPauseBtn");
let isPlaying = false;
function togglePlay() {
if (isPlaying) {
backgroundMusicAudio.pause();
playPauseButton.textContent = "Play";
} else {
backgroundMusicAudio.play();
playPauseButton.textContent = "Pause";
}
isPlaying = !isPlaying;
}
</script>
This creates a simple background music player that loops continuously and can be toggled between play and pause. đ§
Example 5: Looping Sound Effects in a Game
This example demonstrates how to loop sound effects in a simple game scenario:
<button onclick="playSoundEffect()">Play Sound Effect</button>
<audio id="soundEffect" loop>
<source src="https://www.w3schools.com/tags/horse.ogg" type="audio/ogg" />
Your browser does not support the audio element.
</audio>
<script>
const soundEffectAudio = document.getElementById("soundEffect");
function playSoundEffect() {
soundEffectAudio.play();
}
soundEffectAudio.addEventListener("ended", function () {
this.currentTime = 0;
this.play();
});
</script>
Clicking the button will play the sound effect, and it will loop continuously until the user interacts again. đšī¸
