There are onmouseleave and onmouseenter in IE, but it is still a headache for web developers who want to be compatible with major browsers.
Although there are some strategies against Mozilla Firefox on the Internet, the amount of code is not optimistic.
I wanted to find a better solution, so I searched through domestic websites, big and small, but found nothing. I had to bite the bullet and read foreign websites. The result was ideal, because there is relatedTarget in W3C, so I came up with the following Solution:

Copy code The code is as follows:

function isMouseLeaveOrEnter(e, handler) { 
if (e.type != 'mouseout' && e.type != 'mouseover') return false; 
var reltg = e.relatedTarget ? e.relatedTarget : e.type == 'mouseout' ? e .toElement : e.fromElement; 
while (reltg && reltg != handler) 
reltg = reltg.parentNode; 
return (reltg != handler); 
}

Make the above judgment in onmouseover and onmouseout.
