// Navigation: 方向箭头：向左，向右
/* Pagination: 轮播小圆点
clickable: 如果为true，则单击分页按钮将跳转到对应的slide。仅适用于项目符号分页类型
*/
/* Scrollbar: 滚动条
draggable: 设置为true可使滚动条可拖动，从而控制滑块位置
*/
/* AutoPlay: 自动轮播
delay: 转换之间的延迟（毫秒）。如果未指定此参数，将禁用自动播放
disableOnInteraction：设置为false，用户交互（滑动）后自动播放不会被禁用，每次交互后都会重新启动
pauseOnMouseEnter：启用后，指针（鼠标）在Swiper容器上输入时将暂停自动播放。

// 通过class获取dom，并在循环时初始化，为了保证echarts初始化时dom已经更新渲染，加一个setTimeout函数
