新闻轮播图

一、效果图

二、vue中html部分

            

              

                
              
            
            

            
{{ swiperTitle }}
          

三、vue中相关js代码

let state = reactive({     
      timer:null,
      newsImageList:[],
      async getImageList(){
        let data={
          page:PAGEITEM.page,
          size:PAGEITEM.size,
        }
        let res = await getImageList(data)
        if(res.code===SUCCESS_CODE){
          state.newsImageList=res.data.records
        }else{
          state.newsImageList=[]
        }
      },
      swiper: {},
      swiperTitle:'',
      initSwiper() {
        //@ts-ignore
        state.swiper = new Swiper(swiperDom.value, {
          // Swiper的配置选项
          pagination: {//页脚（标题部分）
            el: '.swiper-pagination',
          },
          on:{//这里是为了实现手写title获取
            transitionEnd : function(e){
              let index=(e.activeIndex===(state.newsImageList.length+1))?1:e.activeIndex
              state.swiperTitle=state.newsImageList[index-1].title
            },
          },
          //自动轮播
          autoplay: {
            delay: 2500,//时间 毫秒
            disableOnInteraction: false,//用户操作之后是否停止自动轮播默认true
          },
          loop:true,//循环 最后面一个往后面滑动会滑到第一个
        });
      },
    });
onMounted(async () => {
      await state.getImageList()
      state.timer = setTimeout(() => {
        state.initSwiper();
      }, 100)
    });
onUnMounted(()=>{
    state.timer=null
})

四、less代码

      .swiper-container {
        width: 100%;
        height: 100%;
        position:relative;
        :deep(.swiper-slide) {
          width: 100%;
          height: 100%;

          img {
            width: 100%;
            height: 100%;
          }
        }
        .title{
          height: 50px;
          line-height: 50px;
          position: relative;
          top:-50px;
          color:#fff;
          z-index: 10;
          width: 70%;
          .ellipsis;
        }
        :deep(.swiper-pagination){
          background: rgba(00,00,00,.7);
          height: 50px;
          bottom: 0;
          display: flex;
          justify-content: flex-end;
          align-items: center;
          padding-right: 24px;
          .swiper-pagination-bullet {
            background: rgba(255,255,255,.9);
          }
          .swiper-pagination-bullet-active{
            background: #fff;
          }
        }
      }
