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.
