When utilizing state in ReactJS to modify the color of my button, the change does not take effect on the first click. How can I troub

Whenever I click the button that routes to different locations via an API, the route works fine but the button color doesn't change on the first click.

To address this issue, I implemented the useState hook and CSS to dynamically change the button color. While it works perfectly, the color change is not reflected immediately upon the first click.

Answer №1

When using CRA (create react app) for your project, you have the option to include

activeclassname="active"
in your div tag and define the desired styling in your css/scss file.

import { NavLink } from "react-router-dom";

<NavLink to="/some-route" activeclassname="active">
  text
</NavLink>

 & a {
   color: red
   &.active {
      color: blue;
   }
}

If you are working with Vite instead of CRA, there is no need for activeclassname. Simply use:

<NavLink to="/some-route">text</NavLink >

 &.active {
    color: $blue;
 }

Answer №2

It seems that the lack of color change on the first click is due to a delay in updating the state, preventing the button from reflecting the new color. This issue often arises when the state update process becomes asynchronous.

To address this problem and ensure prompt state updates, consider utilizing the useEffect hook alongside the useState hook for improved functionality.
