Creating Pagination in Vanilla JavaScript: A Step-by-Step Guide

If you've ever tried to create a dynamic table in JavaScript, you might have encountered the need for pagination—the ability to display a limited number of rows at a time while allowing users to navigate through multiple pages. This is essential for improving user experience, especially when handling large amounts of data. In this guide, we will walk through how to implement pagination in vanilla JavaScript, without relying on any frameworks or libraries.

Understanding the Problem

You might be asking yourself, "How do I manage the number of rows displayed and allow users to move between different pages?" This is a common issue, especially when you're building a sortable and dynamic table. The goal is to limit the display to 20 rows at a time and provide navigation buttons for users to easily move back and forth between pages.

Our Solution

Here's a step-by-step breakdown of how to implement pagination in your JavaScript project.

Step 1: Setting Up the HTML Structure

Before diving into the JavaScript code, let’s establish a basic HTML structure that will accommodate our pagination. Your HTML might look like this:

Step 2: Writing the Pagination Logic

Next, we need to implement the loadTableData() function, which will manage which rows get displayed based on the current page number. Here’s how to do it:

Step 3: Control the Pagination Buttons

Now that we can load data based on the page number, we need to implement functions to navigate between pages:

Step 4: Initialize the Data on Page Load

Finally, we should call our loadTableData function when the window loads to display the first set of rows:

Conclusion

By following this guide, you should now have a working pagination feature for your dynamic table, all powered by vanilla JavaScript. The key components we covered include setting up the HTML structure, writing the pagination logic to handle row slicing, and controlling the page navigation buttons.

Implementing pagination in your JavaScript applications enhances usability and make your data presentation much cleaner. Happy coding!
