vue3+typeScript穿梭框的实现示例

<div class="shuttle">
  <!-- 左边列表 -->

      <div>列表一</div>

      <div class="shuttle-box-item" v-for="(vo,inx) in itemLeft" :key="inx">
        <input type="checkbox" :value="inx" v-model="checkLeft" :disabled="vo.disabled" /> {{vo.label}}
      </div>
    </div>
  </div>
  <!-- 左右操作按钮 -->
  <div class="shuttle-click">
    <span @click="goLeft">←</span>
    <span @click="goRight">→</span>
  </div>
  <!-- 右边列表 -->
  <div class="shuttle-box">
