How to Swap Input from Two Text Fields Using HTML and JavaScript
Are you looking to create an interactive feature on your web page that allows users to swap the text from two input fields? Swapping values with JavaScript can be a fun and useful addition to your website's functionality. In this guide, we will guide you step by step on how to implement this feature seamlessly.
The Problem: Swapping Text Inputs
Imagine you have two text fields on your web page, and you want to give users the option to quickly swap their inputs. For example, if a user types "Craig" in the first field and "Kelly" in the second, clicking a button should cause those inputs to swap places. The goal is to make this process as intuitive and smooth as possible.
The Solution Overview
To implement the swapping mechanism, we’ll write a simple JavaScript function along with the HTML structure. Follow these steps to achieve the desired functionality.
Step 1: Setting Up the HTML Structure
First, we need to create the HTML layout for our input fields and the buttons that will trigger the swap and clear functions. Here’s how you can set it up:

Explanation of the JavaScript Code
Getting Input Values:
The function starts by retrieving the values from both text fields using document.getElementById.
Swapping Logic:
The values are swapped using a temporary variable called temp.
Updating Values:
After swapping, the new values are assigned back to the respective text fields using the value property.
Clearing the Fields:
The clearText function is straightforward; it sets the value of both fields to an empty string, effectively clearing them.
