How to Decorate Buttons with a Spinner in jQuery for AJAX Calls

When building user interfaces that include buttons tied to AJAX calls, providing feedback to users while they wait for a response is essential. One way to enhance user experience is by displaying a spinner on the button while an API call is in progress. This post will guide you through the process of implementing a button spinner in jQuery, ensuring it's both reusable and efficient.

Problem Overview

The concept is simple: every time a user clicks a button that makes an API call, the button should be temporarily disabled and show a loading spinner until the request completes. Initially, you might write redundant code for each button, leading to inefficiencies and higher maintenance costs. In this guide, we'll create a reusable function to streamline this process.

Step-by-Step Solution

1. Setting Up the Environment

First, you need to include jQuery in your HTML and create a simple button along with a hidden spinner element. Here's what your basic HTML structure should look like:

2. Creating the Spinner Function

Next, we will define a function that handles the spinner's activation and deactivation process. This function will take two parameters: the button that was clicked and a function representing the AJAX call.

3. Implementing the AJAX Call

For the sake of demonstration, we will simulate an AJAX call with a timeout function wrapped in a Promise. In practice, this would be replaced with your actual AJAX request.

4. Binding the Click Event

Finally, we will bind the button click event to our spinner function, passing the button and the AJAX simulation function as arguments.

Full Example

Bringing all these parts together, your complete JavaScript code will look like this:

Conclusion

By implementing the above structure, you will have a reusable function that decorates any button with a spinner during AJAX calls. This not only improves user experience but also enhances code maintainability by reducing redundancy. Feel free to adapt the spinner and AJAX function for your specific needs.
