Step 3: Create Form.js Component

Here, we will create Form.js component and make form. Then we will add form with "name" and "email" input fields. so let's update code on following file.

src/Form.js

import React from 'react';
 
class Form extends React.Component {
  
  state = {
    name: '',
    email: ''
  };
  
  /*------------------------------------------
  --------------------------------------------
  handleChange() Code
  --------------------------------------------
  --------------------------------------------*/
  handleChange = (event) => {
    const input = event.target;
    const value = input.value;
 
    this.setState({ [input.name]: value });
  };

  /*------------------------------------------
  --------------------------------------------
  handleFormSubmit() Code
  --------------------------------------------
  --------------------------------------------*/
  handleFormSubmit = (e) => {
    e.preventDefault();

    const inputData = this.state;
    console.log(inputData);
  };
 
  render() {
    return (
      <div>
        <form onSubmit={this.handleFormSubmit}>
          <label>
            Name: <input name="name" className="form-control" value={this.state.name} onChange={this.handleChange}/>
          </label>
          <label>
            Email: <input name="email" className="form-control" value={this.state.email} onChange={this.handleChange}/>
          </label>
          <button type="submit" className="btn btn-success  ">Submit</button>
        </form>
      </div>
    )
  }
}
 
export default Form;

Step 4: Update App.js File

Here, we will update our App.js file code. we will import Form component and import bootstrap for design. so let's update code on App.js file.

src/App.js

import './App.css';
import 'bootstrap/dist/css/bootstrap.min.css';

import Form from './Form';

function App() {

  return (
    <div className="App container">
      <h1>How to Get Input Box Value in React JS? - MyWebtuts.com</h1>

      <Form />

    </div>
  );
}

export default App;
