最近因为项目上的需求，需要切换两个轮播图。于是出现了一个很尴尬的问题，第一个Swiper可以正常切换，但是第二个轮播图却无法正常运行，卡顿。
检查了代码后发现问题主要来源于display:none;
我加上了这个隐藏属性后，第二个轮播一定会出问题。
最终解决方式：
1）需要加上这两个属性
observer:true,//启动动态检查器(OB/观众/观看者)，当改变swiper的样式（例如隐藏/显示）或者修改swiper的子元素时，自动初始化swiper。
默认false，不开启，可以使用update()方法更新。
observeParents:true,//将observe应用于Swiper的父元素。当Swiper的父元素变化时，例如window.resize，Swiper更新
2）将display:none;这个隐藏的css换一中隐藏方式。
.hide{visibility: hidden;position: absolute;z-index: -1;height: 0;}
3）因为是有多个轮播图的，所以在实例化的时候，不能使用相同类型，最好分开。
var swiper = new Swiper('这里需要更改', {
pagination: {
el: '这里需要更改',
clickable: true,
},
});
