Check if a button is clicked using JavaScript

In this tutorial, we are going to learn about how to check if a button clicked or not using JavaScript.

Consider, we have a following html button element.

<button id="btn">Hello</button>

Now, we need to check if a button is clicked or not.

Checking if a button is clicked

To check if a button is clicked, first we need to access the button element inside the JavaScript using the document.getElementById() method, then add a click eventListener to it.

Here is an example:

const button = document.getElementbyId("btn");

button.addEventListener("click", ()=>{
   alert("button is clicked");
})

In the code above, we have added an alert button is clicked inside the addEventListener() method. So, if a user clicks on the button it shows an alert inside the browser that button was clicked.

We can also count, how many times a button is clicked like this:

Here is an example:

const button = document.getElementbyId("btn");

let count = 0;

button.addEventListener("click", ()=>{
   count = count + 1;
   alert("button is clicked" + count);
})
