JavaScript - How to clear an Input Field Value

In this tutorial, we are going to learn about how to clear the input field value in form using the JavaScript.

We mostly clear the form input field values after submitting a form or clearing the cluttered form.

Clearing the input field value with button click

Consider, that we have a following input field value with a button element.

<input type="text" placeholder="Name" id="name"/>
<button id="btn">Clear input field</button>

To clear the above input field by clicking a Clear input field button, first we need to access these elements inside the JavaScript by using document.getElementId() method.

const inputField = document.getElementById("name");
const btn = document.getElementById("btn");

Now, we need to attach a click event to the button element and set a inputField.value property to an empty string " ".so that when a user clicks on the button, input field value is cleared.

btn.addEventListener('click',()=>{
    // clearing the input field
    inputField.value = " ";
})
