Changing the src attribute of an image using JavaScript

This article explains how to dynamically change the src attribute of an image element in JavaScript. This allows you to load different images into the same image element, potentially from user input or an external source.

Understanding the src attribute

The src attribute of an image element (<img>) defines the source of the image to be displayed. It takes a URL string as its value, pointing to the image file on the web.

Changing the src attribute with JavaScript

Here's a basic example of how to change the src attribute of an image using JavaScript:

// Get the image element by its ID
const myImage = document.getElementById('myImage');

// Change the src attribute to a new image URL
myImage.src = 'path/to/new/image.jpg';

In this example:

1. We use document.getElementById() to retrieve the image element with the ID "myImage".
2. We set the src property of the image element to a new URL, effectively loading a different image into the same element.

Example with user input

This example demonstrates changing the image source based on user input:

In this example:

1. We have an image element with an initial source.
2. A text input field allows the user to enter a new image URL.
3. A button triggers the changeImage() function when clicked.
4. The changeImage() function gets the input value and updates the src attribute of the image element, displaying the image specified by the user.

Conclusion

Changing the src attribute of an image element allows you to dynamically update the image displayed on your web page. This functionality can be combined with various events and user interactions to create dynamic and engaging user interfaces.
