How to work with document.embeds in JavaScript ?
Last Updated :
01 May, 2024
The document. embeds is a property in JavaScript that provides access to all embedded elements such as <embed> and <object> tags within the current document. These embedded elements are typically used to display external content, such as media files (e.g., videos, audio) or interactive content (e.g., Flash animations).
Below are the approaches to show how you can work with the document. embeds property:
Accessing Embedded Elements
Accessing embedded elements involves using the document. embeds property, which returns a collection of all embedded elements (<embed> and <object> tags) within the current document. This collection can be iterated over to work with individual embedded elements.
Example: The below code practically implements the document.embeds property to access all embedded elements.

function displayEmbedInfo() {
let embeds = document.embeds;
let embedInfoDiv =
document.getElementById('embedInfo');
embedInfoDiv.innerHTML = '';
let embedCount = embeds.length;
console.log(embedCount)
let embedCountText =
document.createElement('p');
embedCountText.textContent =
'Number of embedded elements: ' + embedCount;
embedInfoDiv.appendChild(embedCountText);
for (let i = 0; i < embedCount; i++) {
let embed = embeds[i];
let embedParameters = document.createElement('p');
embedParameters.textContent =
'Embedded Element ' + (i + 1) + ' - Type: ' +
embed.tagName + ', Source: ' + embed.src;
embedInfoDiv.appendChild(embedParameters);
}
}
window.onload = displayEmbedInfo;

Working with Embedded Elements
Once you have access to an embedded element, you can interact with it by accessing its properties and methods. The specific properties and methods available depend on the type of embedded element and its implementation. You can manipulate embedded elements by controlling their playback, changing their attributes, etc.
Example: The below code will show the use of embeds property to work with embedded elements.

<!-- This div will be replaced with the

<div id="youtube-player"></div>

function onYouTubeIframeAPIReady() {
player = new YT.Player('youtube-player', {

}
});
}
// Pause the video after 5 seconds

This HTML snippet embeds a YouTube video that pauses after 5 seconds. It loads the YouTube Iframe API in the head section and sets up a div in the body where the YouTube player will be created. The onYouTubeIframeAPIReady() function initializes the YouTube player with a specific video ID (oM0HOxae8_A) and sets it to autoplay. A setTimeout function pauses the video after 5 seconds by calling player.pauseVideo(), ensuring the YouTube player is properly initialized and has the pause functionality. This setup creates a YouTube video that automatically stops after a brief delay.
