How to prohibit the bottom of the scroll when there is a pop-up layer (to achieve the surface sliding, the bottom is forbidden to slide, the surface is hidden, the bottom can still slide);

   function (event) {         if (plus one condition is to determine when the surface page appears ) {             event.preventdefault ();         }     },false);
