What triggers the onmouseout event to occur?

Is the event triggered continuously whenever the mouse is not hovering over the element? Or is it a one-time action when the mouse exits the element? This distinction is crucial for me to determine when the mouse pointer leaves the element, while only wanting to know when it re-enters. I want to avoid my script running repeatedly while the mouse pointer is away from the element.

Answer №1

Whenever a user moves their mouse out of an element, the mouseout event is triggered. Unfortunately, these events have a bubbling effect.

To prevent the event from bubbling up, simply include event.stopPropagation();

Answer №2

When the mouse leaves an element, the mouseout event is triggered (for example, when the mouse moves away from an image on a web page).

Source: MDN

This suggests that the event only occurs once rather than continuously, as the mouse can only leave the element at one specific moment in time. Once the mouse is no longer over the element, the event is activated.
