When a mouse wheel is being scrolled over an element, the onwheel attribute triggers.
Example
You can try to run the following code to execute a script when a mouse wheel is being scrolled over an element in HTML −
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div id = "myDIV" onwheel = "display()">This is demo text. Roll the mouse wheel here.</div>
<script>
function display() {
alert("Mouse Wheel used!");
}
</script>
</body>
</html>
