How to Submit a Form Using Enter Key in React.js?

In this tutorial, we will explore different approaches to submit a form in React.js when the Enter key is pressed. We will cover both class components and functional components.

Using an Event Listener

If you are using a class component, you can add an event listener to the input field to detect the Enter key press and trigger the form submission. Here’s an example:

{`
  import React, { Component } from 'react';

  class Form extends Component {
    handleSubmit = (event) => {
      event.preventDefault();
      // Perform form submission logic here
    }

    handleKeyPress = (event) => {
      if (event.key === 'Enter') {
        this.handleSubmit(event);
      }
    }

    render() {
      return (
        

          
        
      );
    }
  }

  export default Form;
  `}
  

Using React Hooks

If you are using a functional component with React Hooks, you can use the useEffect hook to add an event listener to the input field. Here’s an example:

{`
  import React, { useEffect } from 'react';

  const Form = () => {
    const handleSubmit = (event) => {
      event.preventDefault();
      // Perform form submission logic here
    }

    const handleKeyPress = (event) => {
      if (event.key === 'Enter') {
        handleSubmit(event);
      }
    }

    useEffect(() => {
      document.addEventListener('keypress', handleKeyPress);

      return () => {
        document.removeEventListener('keypress', handleKeyPress);
      }
    }, []);

    return (
      

        
      
    );
  }

  export default Form;
  `}
  

Conclusion

Submitting a form using the Enter key in React.js can be achieved by adding an event listener to the input field. Whether you are using a class component or a functional component with React Hooks, you can easily detect the Enter key press and trigger the form submission. Choose the approach that best suits your project requirements.
