In this blog post, we’re going to go over how to change the image on a link when it’s clicked. We’ll be using javascript and HTML.

This tutorial will cover the basics of what you need to know about JavaScript before starting with this topic.

1. What is the onclick event in JavaScript

The onclick property of the HTML DOM Event Object is used to execute code when an element is clicked. The code goes within curly brackets <> and should be placed inside a function. Example:

This will pop up “hello world” when you click this button.

2. How to change an image when you click it?

To begin, look at the code below and identify what changes when you click on a button:

So, the code is extremely simple and easy to understand! As you can see, we use a “button”. Inside of that button, we have placed an onclick event to call our changeImg function.

Essentially all this does is make it so when the button is clicked, it will change the src (i.e., source) attribute which tells the page where to find your image.

This changes what shows up inside of your img tag (which was empty before). Then looks up an element with a certain ID, and sets its src to the file path of the image.

# Set an onClick listener on an Image in React

To set an onClick listener on an image in React:

Set the onClick prop on the image element.
The function you pass to the prop will get called every time the image is clicked.

Copied!
const App = () =>  const handleClick = event =>  // 👇️ refers to the image element console.log(event.target); console.log('Image clicked'); >; return ( div> img src="https://bobbyhadz.com/images/blog/react-prevent-multiple-button-clicks/thumbnail.webp" alt="car" onClick=handleClick> /> div> ); >; export default App;

We set the onClick prop on the image element, so every time the element is clicked, the handleClick function gets invoked.

Copied!
img src="https://bobbyhadz.com/images/blog/react-prevent-multiple-button-clicks/thumbnail.webp" alt="car" onClick=handleClick> />

If you need to access the image element in your handleClick function, access the target property on the event object.

Copied!
const handleClick = event =>  // 👇️ refers to the image element console.log(event.target); console.log('Image clicked'); >;

If the event is not being triggered, make sure your image element doesn’t have the CSS property pointer-events set to none .

# Passing a parameter to the handleClick function

If you want to pass a parameter to the handleClick function, set the onClick prop to an inline arrow function.

Copied!
const App = () =>  const handleClick = (event, message) =>  // 👇️ refers to the image element console.log(event.target); console.log(message); console.log('Image clicked'); >; return ( div> img src="https://bobbyhadz.com/images/blog/react-prevent-multiple-button-clicks/thumbnail.webp" alt="car" onClick=(event) => handleClick(event, 'hello')> /> div> ); >; export default App;

Notice that we are passing a function to the onClick prop and not the result of calling one.

Copied!
img src="https://bobbyhadz.com/images/blog/react-prevent-multiple-button-clicks/thumbnail.webp" alt="car" onClick=(event) => handleClick(event, 'hello')> />

If you invoke the function when passing it to the onClick prop, e.g. onClick= , it would get immediately called when the component mounts.

# Set an onClick listener on a Local Image in React

You can use the same approach to set the onClick prop on a local image.

Copied!
import MyImage from './thumbnail.webp'; const App = () =>  const handleClick = event =>  // 👇️ refers to the image element console.log(event.target); console.log('bobbyhadz.com'); >; return ( div> img src=MyImage> alt="horse" onClick=handleClick> /> div> ); >; export default App;

The example assumes that you have an image named thumbnail.webp in the same folder as the App component.

For example, if you are importing an image from one directory up, you would import as import MyImage from ‘../thumbnail.webp’ .

The image has to be located in the src directory of your project.

Copied!
img src=MyImage> alt="horse" onClick=handleClick> />

With images from an external URL, you set the src prop of the image to the complete URL.

With local images, you set the src proper of the img tag to the imported image.
