Description
The onmouseenter
event occurs when the mouse pointer enters an element.
The onmouseenter
event is often used together with the
onmouseleave
event, which occurs when the
mouse pointer leaves an element.
The onmouseenter
event is similar to the
onmouseover
event. The difference is that the onmouseenter
event does not bubble
(does not propagate up the document hierarchy). See "More Examples" at the
bottom of this page to better understand the differences.
