Definition and Usage
The mouseenter event occurs when the mouse pointer is over (enters) the selected element.
The mouseenter() method triggers the mouseenter event, or attaches a function to run when a mouseenter event occurs..
Note: Unlike the mouseover event, the mouseenter event only triggers when the mouse pointer enters the selected element. The mouseover event is triggered if a mouse pointer enters any child elements as well. See the example at the end of the page for a demonstration.
Tip: This event is often used together with the mouseleave event.
