 However, when I slide the list up and down, the mouse will automatically drop the list items when it is not in time. How can I restore it to its original state?

This. . . The question was also written too casually and did not clearly state the situation.
Let’s just say.
Using the concept of timer.
Name the timer Timer.
Then set a time, such as the mouse floating on the list is to close the timer.
oDiv.onmouseover=function()
bracket

clearInterval(timer);
