pressMove 方法

if((cr.left + evt.deltaX <= 0) && (cr.right + evt.deltaX >= self.width)){ self.img.translateX += evt.deltaX; }

->

var boxOffX = (document.documentElement.clientWidth - self.width)/2;
if((boxOffX - cr.left - evt.deltaX >= 0) && (cr.right + evt.deltaX - boxOffX>= self.width)){ self.img.translateX += evt.deltaX; }
