Advanced Usage: Handling Events and State

The Chakra UI Input Box can be easily integrated with React state management to create interactive and dynamic input fields.

1. Handling Input Changes

You can use the onChange event to update the value of your input field:

import { useState } from 'react';
import { Input } from '@chakra-ui/react';

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

  const handleChange = (event) => {
    setInputValue(event.target.value);
  };

  return (
    
  );
}

2. Submitting Form Data

The Chakra UI Input Box is frequently used within forms. The onSubmit event can be used to submit data to your backend.

import { useState } from 'react';
import { Input, Button } from '@chakra-ui/react';

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

  const handleChange = (event) => {
    setInputValue(event.target.value);
  };

  const handleSubmit = (event) => {
    event.preventDefault();
    // Submit inputValue to your backend
  };

  return (
    

      
      
    

  );
}
