Salin kod Kod adalah seperti berikut:

(fungsi($){

        var mdx,mmx,isDrag=false,unitStep=40,current=0;
        var that=$(this);

                isDrag=true;
        }).on('touchmove',function(e){
            e.preventDefault();
            sentuh = e.originalEvent.touches[0]||e.originalEvent.changedTouches[0];
            mmx=touch.pageX;
            if(isDrag){
