React - onWheel example
1
points
In this article, we would like to show you onWheel
event in React.
In the example below, we create <div>
element with a scrollbar. As we scroll the list inside the div with a mouse wheel, onWheel
triggers handleOnWheel
method which displays that list is being scrolled.
Runnable example:
// ONLINE-RUNNER:browser;
// Note: Uncomment import lines while working with JSX Compiler.
// import React from 'react';
// import ReactDOM from 'react-dom';
const appStyle = {
width: '100px',
height: '100px',
overflow: 'scroll',
};
const handleOnWheel = () => {
console.log('onWheel: scrolling the list...');
};
const App = () => {
return (
<div style={{ height: '100px' }}>
<div style={appStyle} onWheel={handleOnWheel}>
<ul>
<li>List_item_1</li>
<li>List_item_2</li>
<li>List_item_3</li>
<li>List_item_4</li>
<li>List_item_5</li>
</ul>
</div>
</div>
);
};
const root = document.querySelector('#root');
ReactDOM.render(<App />, root );
