Displaying Marker Information in Leaflet JS Maps: A Step-by-Step Guide

Leaflet JS is a popular JavaScript library for interactive maps, allowing developers to easily implement features like markers and popups. However, if you're looking to display the information of a selected marker in a DIV outside of the usual popup, you've come to the right place! In this guide, we'll explore how to achieve this in a few simple steps.

The Problem

Imagine you have a map populated with various markers, each representing a significant location. Traditionally, when users click on a marker, a popup appears displaying information about that marker. But in some use cases, you might want to display that information more prominently in a designated DIV on your page instead. This change can enhance user experience by providing an easily viewable area for information that doesn't get dismissed when the popup closes.

The Solution

Let's break down the solution into clear, organized steps. Here's how you can display marker information in a DIV:

Step 1: Set up your HTML Structure

First, ensure you have the necessary HTML structure. In addition to the map, you need a DIV to hold the information:

Step 2: JavaScript Implementation

Now, let's dive into the JavaScript part. The key here is to attach an event listener for the click event on each marker to update the DIV with the corresponding information.

Here's how the modified JavaScript code might look:

Explanation

Marker Creation: We loop through the sites array to create markers for each location.

Popup Binding: Each marker has a popup bound to it, showing the address and description when clicked.

Event Listener: The on('click', () => { ... }) part is crucial! When a marker is clicked, it updates the content of the DIV with the information of that specific marker using document.getElementById('text_info').textContent = site.description;.

Conclusion

By following the steps outlined in this guide, you can easily shift your marker information from popups to a more user-friendly DIV on your webpage. Not only does this improve the visibility of crucial information, but it also enhances the overall user experience when navigating your Leaflet JS map.

Now go ahead and implement this feature in your next map project! Happy coding!
