Chatgpt gpt-4 reply of virtual keyboard in reactJS

write a virtual keyboard with a to z and 0 to 9 , a backspace key , an enter key , using ReactJS.

Here's a simple implementation of a virtual keyboard using ReactJS. The keyboard includes the alphabet (A-Z), numbers (0-9), a backspace key, and an enter key. This example assumes that you have already set up a React project and have the necessary dependencies installed.

```jsx
import React, { useState } from 'react';
import './App.css';

const VirtualKeyboard = ({ onEnter }) => {
  const keys = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';

  const handleKeyPress = (key) => {
    if (key === 'BACKSPACE') {
      onEnter((prevValue) => prevValue.slice(0, -1));
    } else if (key === 'ENTER') {
      onEnter((prevValue) => prevValue + '\n');
    } else {
      onEnter((prevValue) => prevValue + key);
    }
  };

  return (
    <div className="keyboard">
      {keys.split('').map((key) => (
        <button key={key} onClick={() => handleKeyPress(key)}>
          {key}
        </button>
      ))}
      <button onClick={() => handleKeyPress('BACKSPACE')}>Backspace</button>
      <button onClick={() => handleKeyPress('ENTER')}>Enter</button>
    </div>
  );
};

function App() {
  const [inputValue, setInputValue] = useState('');

  return (
    <div className="App">
      <textarea value={inputValue} readOnly />
      <VirtualKeyboard onEnter={setInputValue} />
    </div>
  );
}

export default App;
```

And here's the CSS for basic styling:

```css
/* App.css */
.App {
  display: flex;
  flex-direction: column;
  align-items: center;
  padding: 2rem;
}

.keyboard {
  display: grid;
  grid-template-columns: repeat(10, 1fr);
  grid-gap: 0.5rem;
  padding: 1rem;
}

button {
  background-color: #4caf50;
  border: none;
  color: white;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 16px;
  margin: 4px 2px;
  cursor: pointer;
  border-radius: 8px;
  padding: 8px 16px;
}

textarea {
  width: 100%;
  height: 150px;
  padding: 12px 20px;
  box-sizing: border-box;
  border: 2px solid #ccc;
  border-radius: 4px;
  background-color: #f8f8f8;
  font-size: 18px;
  resize: none;
}
```

This code defines a `VirtualKeyboard` component that takes an `onEnter` callback prop. The `App` component uses this to update the `inputValue` state when a key is pressed. The `textarea` displays the `inputValue`. The virtual keyboard grid is styled using CSS Grid.

Please note that this is a minimal example and does not include features like input validation, error handling, or full accessibility support. You may need to enhance this example to fit your specific requirements.
