移动端上下滑动问题swipe

Question

这个是要求一直滑动中间元素图片，形成一个可以上下滚动的状态 ，现在是将中间元素滑动上去以后，取消不了之前的事件，再滑动之前那个元素时还可以滑动，求大神帮忙解决下

function swipeShow() {

// 给class为slide_sub加上触滑监听事件
//事件，方向，距离（像素为单位），时间，手指数量
$("#slider .slide_sub:eq(1)").swipe({
    swipeUp:function (event, direction, distance, duration, fingerCount) {
            // event.stopPropagation();//阻止冒泡
            // event.preventDefault();//阻止浏览器默认事件
            var index = $(this).index();
            $(".cenTitle").fadeOut(300);

            var prevIndex = index - 1;
            var nextIndex = index + 1;

            // get prev element
            var pe = $("#slider .slide_sub:eq(" + prevIndex + ")");

            var pw = pe.width();
