How to Easily Pass Data Between Forms Using JavaScript

If you're new to HTML, CSS, and JavaScript, you might be wondering if it's possible to pass data from one form to another on the same webpage. This functionality is incredibly helpful for improving user experience, especially in scenarios like multiple search boxes. Imagine a page where a user only needs to enter their search term once, and it automatically populates into other fields. In this guide, we'll delve into how to achieve this with just a little JavaScript.

The Problem

You want to create a user interface where:

Search Box 1: The user types their query.

Search Box 2: Automatically reflects what's typed in Search Box 1.

Search Box 3: Does the same as Search Box 2.

This functionality simplifies the user's experience by ensuring they don't have to repeat themselves when filling out similar forms.

The Solution Overview

To accomplish this, we can utilize JavaScript to listen for input events on the first search box. When the user types, we can update the values of the other search boxes in real-time. Here’s how you can implement this solution in an organized manner.

Step-by-Step Implementation

HTML Structure: Set up the structure of your HTML page with the search inputs.

In this HTML snippet, the first input is where the user types their search. The other two inputs have the class copied-content, which we'll use to identify them in JavaScript.

JavaScript Functionality: Use JavaScript to add an event listener that updates other search inputs when content is entered.

Here’s a breakdown of the JavaScript code:

We select all elements with the class copied-content and store them in otherSearchBars.

We then add an input event listener to the first search input. Inside this function, we get the current value typed by the user.

Lastly, we loop through each input in otherSearchBars and set its value to match the first input.

Complete Example

Combining everything, the final implementation looks like this:

Conclusion

Passing data from one form to another using JavaScript is not only straightforward but also enhances the user experience significantly. By following the steps outlined above, you can create an interactive and user-friendly interface that saves time and effort for your users.

Now, when they type in Search Box 1, Search Boxes 2 and 3 will reflect their input instantly. This method is ideal for various applications beyond search forms, making it a handy skill in web development.
