How to Collect User Input and Display It Dynamically on the Same Page in JavaScript

As a beginner in JavaScript and programming, you might encounter the challenge of creating a webpage that allows users to input data, which will then be displayed on the same page in a formatted manner. This includes wrapping the user's input in HTML tags to create a cohesive layout. In this post, we’ll address the problem and guide you through a straightforward solution to achieve this.

Step 3: Understanding the Code

Here’s what happens in the myFunction:

Retrieve Input Values: It captures the values from the input fields.

Clear Previous Output: Ensures that any old outputs are cleared when the function is activated again.

Check for Input: If any of the fields are filled, it proceeds to create new elements.

Creating Elements: Using createElement(), the function creates new HTML elements depending on which input fields are filled, and then appends them to the output_area division.

Display a Message: If no input is provided by the user, it will display a message "No text!"
