Let's say you have a <div> element which is hidden.
There is a mouseover event attached to it and the mouse cursor is placed at the location where the <div> element will appear once it is visible.

你不能。当鼠标位于 Gecko 中的新元素上方时，无论是由于鼠标移动还是元素移动，都会触发该事件。这是很有目的的；当鼠标不移动时，它使得 CSS
:hover之类的东西正常工作。You can't. The event is fired when the mouse is over a new element in Gecko, whether due to the mouse moving or elements moving. This is quite purposeful; it makes things like CSS
:hoverwork correctly when the mouse is not moving.
