html代码

<div class="cplvfx">
  <van-field
  v-model="AddVal"
  is-link
  readonly
  placeholder="请选择活动地区"
  @click="SelectAddStatus = true"
  />

  <van-popup v-model="SelectAddStatus" round position="bottom">
    <van-cascader
    v-model="SelectAddVal"
    title="请选择所在地区"
    :options="AreaData"
    active-color="#17BF8C"
    @close="SelectAddStatus = false"
    @change="AddSelectChange"
    @finish="AddSelectFinish"
    />
  </van-popup>
</div>

js 代码

一，引入必要组建

import { Popup } from 'vant';
import { Cascader } from 'vant';
import { Field } from 'vant';


Vue.use(Popup);
Vue.use(Cascader);
Vue.use(Field);

二、参数

export default {
data(){
  return{
   SelectAddStatus:false,//地址选择状态
   SelectAddVal:'',//地址值
   AddVal:'',//地址值
  }
},
created:(){},
methods:{
    //地址选择发生变化
    AddSelectChange({ value, selectedOptions, tabIndex }){
      console.log('地址选择发生变化');
      console.log(value);
      console.log(selectedOptions);
      console.log(tabIndex);
    },
    //地址选择完成
    AddSelectFinish({ value, selectedOptions, tabIndex }){
      console.log('地址选择完成');
      console.log(value);
      console.log(selectedOptions);
      console.log(tabIndex);
      this.SelectAddStatus = false;
      this.AddVal = selectedOptions.map((option) => option.text).join('/');
      console.log('this.SelectAddVal===');
      console.log(this.SelectAddVal);
      console.log('this.AddVal===');
      console.log(this.AddVal );
    }

},
}
