How to Clear Input Fields in Javascript

In this tutorial, you will learn how to clear input fields on button click in javascript. Whenever you create a form whether it’s for login or signup, you must provide your visitor the ability to reset the form, which eventually will clear all input fields.

If you are using the form element, then you can use the reset() method. It will simply take your form back to its initial state.  We are not going to use the form element in this tutorial, but only input elements.

An input element has a value property that can be used to get and set the value. We can take advantage of this property to clear an input field by setting the value to an empty string.

In the following example, we have 2 input fields and a button element. Upon click of a button, we will clear both the input fields. Please have a look over the code example and the steps given below.


  • We have 3 elements in the HTML file (div, input, and button). The div element is just a wrapper for the rest of the elements.
  • The button element has “Clear” as innerText.
  • 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">
    <link rel="stylesheet" href="style.css">
        <input type="text" placeholder="Enter Username">
        <input type="password" placeholder="Enter Password">
    <script src="script.js"></script>
body {
    text-align: center;

div {
    display: inline-block;

input, button {
    display: inline-block;
    padding: 10px 20px;


  • We have selected the button element using the document.querySelector() method and stored it in the btnClear variable.
  • We have selected both the input elements using the document.querySelectorAll() method and stored it in the inputs variable. This variable holds an array of input elements.
  • We have attached a click event listener to the button element.
  • In the event handler function, we are calling forEach() method of inputs array and in the callback function, we are setting value property to an empty string for each input element.
let btnClear = document.querySelector('button');
let inputs = document.querySelectorAll('input');

btnClear.addEventListener('click', () => {
    inputs.forEach(input =>  input.value = '');
