swiper内部有个横向滚动的盒子
由于swiper滚动，导致滚动盒子的时候自动跳到了下一页
wiper提供一个 noSwipingClass的属性，用来阻止自带的滚动事件
window.mySwiper = new Swiper('#Jswiper', {
direction: 'vertical',
mousewheelControl: true,
speed: 700,
initialSlide: 0,
autoplay: false,
loop: false,
touchMoveStopPropagation: false,
noSwipingClass : 'J_scroll',
nextButton: '.icon-btn',
onInit: function() {
},
onTransitionStart: function(mySwiper) {
if (mySwiper.activeIndex == ($('.part').length - 1)) {
$(".icon-btn").hide();
} else {
$(".icon-btn").show();
}
}
});
