vue-cli 中多个组件共用一个mt-checklist

// html

<div v-if="dataList">
   <mt-popup v-model="popupVisible" position="bottom" class="mint-popup" style="width: 100%;height: 30%;">
        <mt-picker  :slots="dataList" @change="onDateChange" :visible-item-count="5" :show-toolbar="false"  ref="picker" value-key="name"></mt-picker>
      </mt-popup>
 </div>

　　

data(){
  popupVisible:false, // 默认隐藏
  a:0,           // 设置一个标识
}

value-key="name" 必须与option[{name:''}] 一致
