        <block a:for="swiperList">

          <swiper-item class="swiper-box">

            <view class="swiper-item" style="width:100%;height:300rpx">

                <!-- lazy-load根据需要 onTap可以点击图片跳转 data-url绑定到跳转的链接-->

              <image lazy-load="true" mode="scaleToFill" src="item.image" style="display:flex;width:100%;height:300rpx"

                onTap="swiper" data-url="item.url" data-index='index' />

            </view>

          </swiper-item>

        </block>

      </swiper>

    <!-- 圆点 -->

      <view class="swiper_dot">

        <view class="trans MR10 current === index ?'active': ''" a:for="swiperList" a:key="index"></view>

      </view>

</view>

        ,

               

            image:'',

            url:""

       

    ],

    current: 0,//初始化dot
