Create Pagination for a Dynamically Created Table in JavaScript

When working with data fetched from an API, displaying all of that information at once in a single table can overwhelm users. Imagine fetching 100 records and presenting them in one massive table—it's just not practical! Instead, we can use pagination to display a certain number of entries per page, making the data more manageable and easier to navigate.

In this post, we will explore how to create a pagination function for a dynamically generated table using JavaScript, HTML, and CSS.

Understanding the Problem

You have a table populated with data fetched from an API, and you want to implement pagination. The goal is to present the data in smaller, more digestible portions (pages), improving the user experience.

Sample Data

For illustration, we will use an example JSON dataset fetched from an API. Each record in the dataset is intended to populate a row in our table.

Implementation Steps

To create pagination for our dynamically created table, we will break down the solution into several critical sections:

1. Set Up Your HTML Structure

First, we need a simple HTML structure that will hold our table and pagination buttons:

2. Fetch the Data and Populate the Table

Next, we need to fetch the data from the API and dynamically populate the table. Here's how you can do that:

3. Create Pagination Functions

a. Calculate Total Page Count

We need to determine how many pages are needed based on our total records and the specified rows per page:

b. Calculate Remaining Records

Handle the last page's contents, which may have fewer records than the specified rows per page:

c. Populate the Table

This function replaces the HTML of the table with data based on the current page's start and end indexes:

4. Create Pagination Buttons

To navigate through pages, we'll generate buttons dynamically:

5. Style the Pagination (Optional)

You can also enhance the appearance of the pagination buttons with some CSS:

Conclusion

Implementing pagination in a dynamically created table not only enhances usability but also organizes large datasets effectively. With just a few lines of JavaScript and proper HTML structure, you can display your data in a user-friendly manner.

Now you can take your web applications to the next level by adding pagination to your tables!

Happy coding!
