对于你这段代码，最简单的修改办法是把
if (closeB!=0){
collection[closeB-1].object.style.display = 'none';
return;
}

这一段，移到play方法的最后，也就是

followObj.style.display = '';
}
的后面，变成

function play()
{
if(screen.width<=648 ) {
for(var i=0;i<collection.length;i++) {
collection[i].object.style.display = 'none';
}
return;
}
for(var i=0;i<collection.length;i++) {
var followObj = collection[i].object;
var followObj_x = (typeof(collection[i].x)=='string'?eval(collection[i].x):collection[i].x);
var followObj_y = (typeof(collection[i].y)=='string'?eval(collection[i].y):collection[i].y);

if(followObj.offsetLeft!=(document.body.scrollLeft+followObj_x)) {
var dx=(document.body.scrollLeft+followObj_x-followObj.offsetLeft)*delta;
dx=(dx>0?1:-1)*Math.ceil(Math.abs(dx));
followObj.st
