Displaying Counting Numbers with Thousands Separator in JavaScript

Have you ever wanted to create a visually appealing counter that not only counts up numbers but also formats them for easier readability? In this guide, we'll explore a common scenario: how to display a counting number, such as 90,000, in JavaScript with a thousands separator while it's counting up. If you're new to JavaScript, don't worry! We'll break down the solution step by step.

The Problem

You want to create a counting animation where numbers count up from 0 to a specific value, and you want that value to have a thousands separator. For example, instead of simply displaying 90000, you want to display it as 90,000 during the counting process. The existing code can start with numbers but doesn't format them appropriately.

Example of Desired Output

Before Counting: 0

During Counting: 1, 2, 10, 100, ..., 90,000

Final Count: 90,000

The Solution

To achieve this, we will refine our counting code by introducing a number formatter and adjusting our HTML and JavaScript. Let's break this down into manageable steps.

Step 1: Update HTML Structure

We need to ensure that our HTML uses data-* attributes to hold the counting number and its current state. Here’s how you can modify your HTML:

Step 2: Refine Your JavaScript

Now, let’s enhance the JavaScript code. This code will include the number formatting feature to add the thousands separator. Use the Intl.NumberFormat object which will handle the formatting for us automatically:

Explanation of the Code

querySelectorAll: Selects all elements with the class number for counting.

Intl.NumberFormat: This object formats numbers according to the locale conventions, adding commas as thousands separators automatically.

Data Attributes: We utilize data-num to store the target counting number and data-state to keep track of the current number state.

Animate Function: This function updates the count over time until it reaches the target, applying formatting to each increment.

Conclusion

With these steps, you'll be able to create an engaging number counting animation that formats numbers with thousands separators, providing a much clearer visual presentation. Not only will it improve the aesthetic appeal of your application, but it will also enhance the user experience by making numerical information much easier to read.
