mouseenter()

The mouseenter() method adds an event handler function to an HTML element. This function is executed, when the mouse pointer enters the HTML element.

When you enter your mouse cursor over the selected element, it triggers the mouseenter event and once the mouseenter event is occurred, it executes the mouseenter() method to attach the event handler function to run.

This event is generally used together with mouseleave() event.

Syntax:

snippet

$(selector).mouseenter()

It triggers the mouseenter event for selected elements.

snippet

$(selector).mouseenter(function)

It adds a function to the mouseenter event.
