React Js reload/refresh image with same URL onClick
React Js reload/refresh image with same URL onClick: In React JS, to reload or refresh an image with the same URL when it's clicked, you can use an onClick event handler. This allows you to update the image without changing its URL, which can improve performance by preventing unnecessary network requests. To achieve this, you can add a unique key attribute to the image element and update it with a new value on each click. This forces React to re-render the image with the same URL, effectively reloading it.

How can I reload/refresh an image in ReactJS with the same URL onClick?
This React.js code snippet demonstrates how to reload or refresh an image with the same URL when clicked.
The code uses the useState and useEffect hooks from React to manage the state of the image.
The imageKey state variable is used to generate a unique key for the image URL. When the image is clicked, the handleClick function is called, which increments the imageKey by 1, triggering a re-render and causing the image URL to change.
The useEffect hook is used to reset the imageLoaded state whenever the imageKey changes.
The image element has a transition effect applied using CSS classes (fade-in and fade-out), controlled by the imageLoaded state.
Additionally, a slight delay is added to the handleImageLoad function to allow the transition effect to take effect.
