How to Avoid Double Clicks in React Handlers: A Simple Guide to Improving User Experience

As developers, one common challenge we face is ensuring a smooth user experience in our applications. If you’ve worked with React, you may have encountered situations where a button needs to be pressed twice before any action occurs. This can be frustrating for users and may lead to confusion. In this blog, we will explore a solution to remove the double-click requirement and effectively use state management in React to simplify the code.

The Problem

Consider a scenario where you have a button that triggers a series of functions when clicked. However, due to the way you’ve set it up, you need to click the button twice for the desired actions to execute. Here’s a snippet of your existing button handler function:

Observations:

The current code checks for two date variables before executing the refetchAll function.

Users experience a delay because they have to click the button twice to trigger the action.

If the code is modified to remove braces and condense it, an error occurs.

The Solution

The main issue at play here is not just how the button handler is structured, but how you are managing state in your component. The key to resolving this issue lies in using React's useState hook properly. Here's how to make the necessary adjustments:

Step 1: Use State Variables

Instead of relying on plain JavaScript variables, utilize React's useState hook to manage your date variables. Here’s a simple example of how you can set them up:

By using useState, any updates made to date1 or date2 will cause your component to re-render, seamlessly updating the UI and preventing the need for a double click.

Step 2: Update the Handler

Now that we have set up state variables, we need to refactor your button handler. Here’s an example, incorporating both state updates and additional actions:

Step 3: Modify the Button

Make sure your button component correctly invokes the btnHandler. Here’s an example markup for your button:

By using a single button click to execute the handler, we are ensuring a much more user-friendly experience.

Final Thoughts

By implementing the above suggestions, you will eliminate the need for double clicks while maintaining a responsive and effective button handler. State management is a crucial aspect of React apps, and understanding how to use useState effectively is liberating for any developer.
