for the file input element in react, the onChange handler triggered when user selects file changes. Is there a handler which triggers user selected file, even if it is the same file

Yes, you can use the onInput event handler in React to trigger an action when the user selects a file, even if it is the same file that was previously selected. This event handler is similar to onChange, but it triggers whenever the value of the input element changes, even if it remains the same.

I see, in that case, it seems that using the onInput event handler may not work as expected for the file input element in this scenario. One alternative approach you can try is to clear the input value programmatically after the user selects a file, even if it is the same file. This will force the onChange event to trigger each time a file is selected.

Here's an example of how you can achieve this:

import React, { useRef } from 'react';

const MyComponent = () => {
  const fileInputRef = useRef(null);

  const handleFileChange = (e) => {
    // Handle the file change event here
    console.log("File selected:", e.target.files[0]);
    
    // Clear the input value to allow selecting the same file again
    fileInputRef.current.value = null;
  };

  return (
    <div>
      <input
        ref={fileInputRef}
        style={{
          visibility: 'hidden',
          position: 'absolute',
        }}
        type="file"
        id="chatImage"
        accept="image/*"
        onChange={handleFileChange}
      />
    </div>
  );
};

export default MyComponent;

By clearing the input value after the file is selected, the onChange event will be triggered each time a file is selected, even if it is the same file.

You're welcome! I'm glad to hear that the solution worked for you. If you have any more questions or need further assistance, feel free to ask. Happy coding!
