How to clear all textbox value in JavaScript?

JavaScript is a powerful programming language that allows you to add interactivity and dynamism to your web pages. One common task you may encounter is clearing the values of multiple textboxes at once. This can be achieved easily using JavaScript. In this article, we will explore how to clear all the textbox values in JavaScript and address some related frequently asked questions.

How to Clear All Textbox Value in JavaScript?

To clear the values of all textboxes in JavaScript, you can iterate through them and set the value property to an empty string. Here’s a simple example:

“`javascript
// Get all textboxes on the page
const textboxes = document.querySelectorAll(‘input[type=”text”]’);

// Loop through each textbox and set the value to an empty string
textboxes.forEach(textbox => {
textbox.value = ”;
});
“`

This JavaScript code finds all the textboxes on the page using the querySelectorAll() method, which selects elements based on a CSS selector. In this case, we’re selecting input elements with a type of “text”. Then, we use the forEach() method to iterate through each textbox and set its value property to an empty string, effectively clearing its content.

Note that if you have other types of input elements on the page, such as checkboxes or radio buttons, this code will not affect them as we specifically target textboxes.

4. What if I have textboxes inside nested elements?
