reactjsHow do I use ReactJS events to handle user interactions?
ReactJS events are used to handle user interactions such as mouse clicks, key presses, and form submissions. React provides a SyntheticEvent wrapper for cross-browser compatibility. To use ReactJS events, you must add an event listener to a component using the on[event]
syntax. For example, to handle a mouse click event, you would use the onClick
event listener.
class MyComponent extends React.Component {
handleClick() {
alert('Button clicked!');
}
render() {
return (
<button onClick={this.handleClick}>
Click Me
</button>
);
}
}
When the button is clicked, the handleClick()
function is called and the alert is displayed.
Code explanation
class MyComponent extends React.Component
: This declares the component class.handleClick() { alert('Button clicked!'); }
: This is the event handler function that is called when the button is clicked.onClick={this.handleClick}
: This is the event listener that is added to the button and calls the event handler function when the button is clicked.
For more information, see the ReactJS Events documentation.
