Introduction: The Problem at Hand

Have you ever encountered a scenario where you want to change the placeholder text of an input field whenever a user selects an option from a datalist? This small yet crucial detail can significantly enhance user experience by guiding them through inputs and making interfaces more interactive.

For instance, if you have a datalist with various options such as "Farmer", "Customers", and "Suppliers", when a user selects "Farmer", you may want the placeholder to change dynamically to "Search Farmer Here...". Achieving this functionality can be a bit tricky if you're not familiar with event listeners in JavaScript.

In this guide, we’ll go over a simple solution that captures the selected option and updates the placeholder accordingly.

The Solution: Step by Step

Step 1: The HTML Structure

First, ensure you have a basic HTML structure in place. Here’s a simple example where we set up a text input element linked to a datalist.
