    直接封装成组件,多处可以调用,话不多说,上代码

    <template>
      <div class="container">
        <ul>
          <li class="list-item " v-for="(item,index) in list " data-type="0" :key="index">
            <div class="list-box" @touchstart.capture="touchStart" @touchend.capture="touchEnd" @click="skip">
              <img class="list-img" :src="item.imgUrl" alt="">
              <div class="list-content">
                <p class="title">{{item.title}}</p>
                <p class="tips">{{item.tips}}</p>
                <p class="time">{{item.time}}</p>
              </div>
