How to Get Checkbox Value in Javascript

In this tutorial, you will learn how to get checkbox value in javascript. If you are having checkboxes in your HTML file, then it is obvious you want to get the value of the selected checkbox and do something with it.

I am assuming that you are only going to select one checkbox and get its value using javascript. Getting values of multiple selected checkboxes is out of the scope of this tutorial.

In the following example, we have multiple checkboxes. I will select one checkbox randomly and upon click of a button, I will display its value or label text on the screen. Please have a look over the code example and steps given below.


  • We have a few elements in the HTML file and that includes div, label, button, and h1.
  • The div element is just a wrapper for the rest of the elements.
  • We have created multiple checkboxes using input element.
  • The inner text for the button element is “Show” and for the h1 element is “Result”.
  • We have done some basic styling using CSS and added the link to our style.css stylesheet inside the head element.
  • We have also included our javascript file script.js with a script tag at the bottom.
<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <link rel="stylesheet" href="style.css">
        <label><input type="checkbox" value="orange">Orange</label>
        <label><input type="checkbox" value="apple">Apple</label>
        <label><input type="checkbox" value="mango">Mango</label>
        <label><input type="checkbox" value="kiwi">Kiwi</label>
    <script src="script.js"></script>
body {
    text-align: center;

    display: inline-block;

button {
    display: block;
    margin: 20px auto;


  • We have selected button element and h1 element using document.querySelector() and stored them in btnShow and result variables respectively.
  • We have attached the click event to the button element.
  • We are using CSS selector input[type="checkbox"]:checked to get selected checkbox and storing it in checkbox variable.
  • As you can see each input element is wrapped with a label element. That means the label element is the parent of the input element. In javascript, each element has parentElement property which we can use to get the parent element.  Similarly, we can get text content using the textContent property.  We are using both of them to get the label text of the selected checkbox.
  • You can also get the value of the selected checkbox by using the value property.
let btnShow = document.querySelector('button');
let result = document.querySelector('h1');

btnShow.addEventListener('click', () => {
    let checkbox = document.querySelector('input[type="checkbox"]:checked');
    result.innerText = checkbox.parentElement.textContent;
