Change Image Using JavaScript

You can use JavaScript to dynamically change the URL of an image on a webpage. Here's a brief explanation of how to achieve this:

To change the URL of an image using JavaScript, you'll need to follow these steps:

HTML of the Image

First, make sure you have an HTML image element that you want to update. Give it an id so that you can easily target it with JavaScript. For example:

<img id="myImage" src="initial-image.jpg" alt="Initial Image">

JavaScript Code

Next, write JavaScript code to change the src attribute of the image element. You can use an event trigger like a button click or any other user action to initiate this change. Here's an example using a button click event:

// Get a reference to the image element by its id

var image = document.getElementById("myImage");

// Function to change the image URL

function changeImageURL() {

// New image URL

var newImageUrl = "new-image.jpg";

// Update the src attribute of the image

image.src = newImageUrl;

}

HTML Event Trigger

In your HTML, add an element (e.g., a button) that triggers the JavaScript function when clicked:

<button onclick="changeImageURL()">Change Image</button>

Now, when the button is clicked, the changeImageURL() function will run, updating the src attribute of the image element with the new URL. This effectively changes the image displayed on the webpage.
