What is embed in JavaScript?

The term “embed” in JavaScript typically refers to the process of incorporating or integrating external content, such as media, documents, or other resources, into a web page or application.

This can include embedding images, videos, audio files, interactive maps, social media posts, iframes, and more.

Common Way Embedding Content

One common way to embed content is by using the:

  • HTML tag
  • <iframe> tag

Let’s see examples of how it works.

HTML tag

The <embed> tag is often used to embed media files, such as audio or video, directly into a web page.

Here’s a simple example of using the <embed> tag to embed a video:

<embed src="video.mp4" width="500" height="300">

<iframe> tag

The <iframe> tag, on the other hand, is commonly used to embed external web content, such as a map from Google Maps or a social media post.

Here’s an example of embedding a Google Map using an <iframe>:

<iframe src="!1m18!1m12!1m3..."></iframe>

JavaScript can also be used to dynamically embed content into a web page based on user interactions or other conditions.

For example, you can use JavaScript to change the source of an <iframe> element or to create and manipulate elements dynamically to embed content.

Here’s a simple example of dynamically changing the source of an <iframe> using JavaScript:

<iframe id="myFrame" src="initial-page.html"></iframe>

  // Change the source of the iframe
  document.getElementById("myFrame").src = "new-page.html";

How to use embed in JavaScript?

Since, we already know what is embed in JavaScript along with the common ways to it, let’s take deeper on how to use it.

Here’s a step-by-step guide on how to use the <iframe> element to embed content using JavaScript:

  1. Create the HTML Structure

    First, create the HTML Structure for your webpage. Then add an <iframe> element where you want to embed the external content.

    Take the following example:

    HTML structure

  2. Access the <iframe> element

    In JavaScript, you can use the document.getElementById() function to access the <iframe> element by its id attribute.

    Apparently, it allows you to modify its attributes and content.

    For instance:

    Access the iframe element

  3. Change the Embedded Content

    You can change the src attribute of the <iframe> element to embed different content.

    For example, you want to embed a YouTube video. Apparently, you can change the src attribute to the YouTube video’s URL.

    Change the Embedded Content

    Replace “VIDEO_ID” with the actual ID of the YouTube video you want to embed.

  4. Respond to user Interaction

    You can also use JavaScript to change the embedded content based on user interactions.

    For instance, you want to embed different content when the button is clicked.

    Respond to user Interaction

    In this example, clicking the button with the IDchangeButton” will update the embedded content to a different website.

Keep in mind when adding content from outside sources, prioritize security.

Follow best practices to avoid risks like XSS attacks. Only use trusted sources and sanitize user input before embedding in an <iframe>.

How to embed HTML in JavaScript?

Embedding HTML in JavaScript typically involves creating or generating HTML elements using JavaScript and then inserting them into the DOM (Document Object Model) of a web page.

This allows you to dynamically add or modify HTML content based on user interactions, data, or other conditions.

Here’s how you can embed HTML in JavaScript:

Create an HTML Container

Start by creating an HTML container element (e.g., a <div>) where you want to embed the generated HTML content.

Then, give an appropriate id attribute to make it easier to target with JavaScript.

Let’s take this example:

<div id="dynamicContent"></div>

Access the Container Element

Similar to <iframe> tag, embedding HTML in JavaScript we also use document.getElementById() function to access the container element.

Additionally, this will allow you to add or modify content within it.

For example:

const dynamicContentContainer = document.getElementById("dynamicContent");

Generate HTML Elements

Then use JavaScript to create new HTML elements or modify existing ones. Basically, you can use the document.createElement () method to create new elements and set their properties.

For instance, let’s create a simple <p> element with some text.

const paragraph = document.createElement("p");
paragraph.textContent = "This is dynamically generated content.";

Append Elements to the Container

After creating or modifying the HTML elements you need to insert them into the DOM.

Then you use the appendChild() method of the container element to add the generated element as children.

For example:


Respond to User Interaction

Finally, you can trigger the dynamic HTML generation and embedding based on user interactions, such as clicking a button or submitting a form.

Here’s an example of adding to content when a button is clicked:

<button id="generateButton">Generate Content</button>

  const generateButton = document.getElementById("generateButton");

  generateButton.addEventListener("click", function() {
    const paragraph = document.createElement("p");
    paragraph.textContent = "New dynamically generated content.";


In this example, clicking the button with the ID “generateButton” will create a new <p> element with the specified text and add it to the container.
