mouseenter() Method

Events in jQuery are the actions that the user performs on the web page. It can be anything – related to mouse clicks, keyboard presses, etc. Using jQuery, we can control these events in the order we want and can also attach some custom functions to it if needed. That means, we can use predefined event methods for the actions and also define a function that gets fired when the event method is triggered. Overall, this makes the website more dynamic on the user's end. Let's learn about the mouseenter() method here.

The mouseenter() method is a built-in jQuery method. This event gets triggered when the mouse pointer enters the selected element on the page. It gets executed once every time the pointer enters the particular element. The attached function is then fired for the same.

The mouseenter() method only detects the pointer when the mouse enters the parent element. It does not return anything for the child elements of the selected element. For that, we use mouseover() method in jQuery.

mouseenter() Method Syntax

$('selector').mouseenter();
$('selector').mouseenter(function);

It takes one optional parameter – function. The function is the custom function that can be defined to do some tasks when this method gets triggered.

The below example shows how the mouseenter() method gets executed once the mouse enters the selected parent div element. Generally, mouseleave() is used along with the mouseenter() method in jQuery.
