Troubleshooting React onClick Conditional Logic Issues

If you’ve been coding in React for a while, you might find yourself encountering problems when dealing with event handling, especially with the onClick events. A common issue developers run into is when an if conditional seems to malfunction – specifically when it only works the first time it is triggered. In this guide, we’ll explore a specific example of this issue and provide a clear solution to fix it.

Understanding the Problem

Imagine you’ve written a function intended to toggle the display of an element when its parent container is clicked. You want the element to show and hide based on its current style settings. Here’s the code you might have attempted:

Step 2: Explanation of the Changes

State Control: By making sure you’re checking for specific values, you maintain control over the element's visibility across multiple clicks.
