# Create an element with onClick event listener using JS

To create an element with an onClick event listener:

Use the document.createElement() method to create the element.
Use the addEventListener() method to add a click event listener to the element.
Add the element to the page using the appendChild() method.

Here is the HTML for the examples.

index.htmlCopied!<!DOCTYPE html> <html lang="en"> <head> <title>bobbyhadz.com</title> <meta charset="UTF-8" /> </head> <body> <div id="box"></div> <script src="index.js"></script> </body> </html> The code for this article is available on GitHub

And here is the related JavaScript code.

index.jsCopied!// ✅ Create element const el = document.createElement('div'); el.addEventListener('click', function handleClick(event) { console.log('element clicked 🎉🎉🎉', event); }); // ✅ Add text content to the element el.textContent = 'Hello world'; // ✅ Or set the innerHTML of the element // el.innerHTML = `<span>Hello world</span>`; el.style.backgroundColor = 'salmon'; el.style.width = '150px'; el.style.height = '150px'; // ✅ add element to DOM const box = document.getElementById('box'); box.appendChild(el);

We used the document.createElement() method to create the element.

index.jsCopied!const el = document.createElement('div'); The only parameter we passed to the method is the type of element to be created (div in the example).

The createElement method returns the newly created element.

We called the addEventListener() method on the element, passing it the following 2 parameters:

The event type to listen for (click in the example).
A function that gets invoked when the event is triggered.

index.jsCopied!const el = document.createElement('div'); el.addEventListener('click', function handleClick(event) { console.log('element clicked 🎉🎉🎉', event); }); The code for this article is available on GitHubEvery time the element is clicked, the handleClick function is invoked.

You can use the textContent property to set the element's text content or the innerHTML property to set the element's inner HTML markup.

index.jsCopied!// ✅ Create element const el = document.createElement('div'); el.addEventListener('click', function handleClick(event) { console.log('element clicked 🎉🎉🎉', event); }); // ✅ Add text content to the element el.textContent = 'bobby hadz tutorial'; // ✅ Or set the innerHTML of the element // el.innerHTML = `<span>Hello world</span>`; The code for this article is available on GitHubYou shouldn't use the innerHTML property with user-provided data without escaping it. This would leave your application open to cross-site scripting attacks.

You can use the appendChild() method to add the element to the page.

index.jsCopied!// ✅ Create element const el = document.createElement('div'); el.addEventListener('click', function handleClick(event) { console.log('element clicked 🎉🎉🎉', event); }); // ✅ Add text content to the element el.textContent = 'Hello world'; // ✅ add element to DOM const box = document.getElementById('box'); box.appendChild(el); The code for this article is available on GitHub

The method adds a node to the end of the list of children of the element it was called on.

You can also use the onclick attribute to add an event lister after creating the element.

index.htmlCopied!// ✅ Create element const el = document.createElement('div'); el.onclick = function handleClick(event) { console.log('element clicked 🎉🎉🎉', event); }; // ✅ Add text content to the element el.textContent = 'bobby hadz tutorial'; // ✅ Or set the innerHTML of the element // el.innerHTML = `<span>Hello world</span>`; el.style.backgroundColor = 'salmon'; el.style.width = '150px'; el.style.height = '150px'; // ✅ add element to DOM const box = document.getElementById('box'); box.appendChild(el); The code for this article is available on GitHub

The onclick attribute specifies a function to run when the element is clicked.

Either approach works, but the addEventListener method is more commonly used.
