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>
