    <!--swiper全屏轮播Vue组件封装-->
    <!--使用方法：
            1、在主页面中使用  <swiper-vue></swiper-vue>
            2、需要传递的参数
                a)在<swiper-vue></swiper-vue>里面加入要循环的数据，组件中有slot接收
                b)index--为点击后的需要传递到swiper中的图片坐标
                c)Okshow--要设置swiper的显示与隐藏，开始要设置为false,点击图片后设置为true
                d)scroll--为滚动条的位置，关闭swiper后要对滚动条位置进行还原
