javascript - On the mobile terminal, when a mask layer appears, there are divs in the mask layer that exceed the scroll height. How to prevent the body from sliding with it when the div is slid?

Question

1. Add overflow:hidden to the body when clicking to exclude the mask layer, because when the body slides to the bottom and clicks again to display the mask layer, the body will jump to the top by default, and the mask layer is positioned at top. :0;left:0;position:fixed;
2. Exclude the bubbling behavior when p slides, because the scroll event accepts bubbling, but does not support blocking default events and bubbling behavior;
3 , I have tried many times, please give me some advice!

Answer 1
