<template>

        <van-button plain type="primary" @click="showPopFn()">点击选择日期</van-button>
        <van-field v-model="timeValue" placeholder="选择的日期结果" readonly />
        <van-popup v-model="show" position="bottom" :style="{ height: '40%' }">
          <van-datetime-picker v-model="currentDate" type="date" @change="changeFn()" @confirm="confirmFn()" @cancel="cancelFn()" />
        </van-popup>
    
      </div>
    </template>
    
    <script>
      export default {
        data() {
          return {
            msg: '',
            currentDate: new Date(),
            changeDate: new Date(),
            show: false, // 用来显示弹出层
            timeValue: ''
          }
        },
        methods: {
          showPopFn() {
            this.show = true;
          },
          showPopup() {
            this.show = true;
          },
          changeFn() { // 值变化是触发
            this.changeDate = this.currentDate // Tue Sep 08 2020 00:00:00 GMT+0800 (中国标准时间)
          },
          confirmFn() { // 确定按钮
            this.timeValue = this.timeFormat(this.currentDate);
            this.show = false;
          },
          cancelFn(){
            this.show = true;
          },
          timeFormat(time) { // 时间格式化 2019-09-08
            let year = time.getFullYear();
            let month = time.getMonth() + 1;
            let day = time.getDate();
            return year + '年' + month + '月' + day + '日'
          }
        },
        mounted() {
          this.timeFormat(new Date());
        }
      }
    </script>
    
    <style>
    </style>

注意：如果是按需引入的话，记得在main.js里面引入相应的文件奥。

// main.js文件里面的部分代码
    import {Button} from 'vant'
    import { DatetimePicker } from 'vant';
    import { Popup } from 'vant';
    import { Field } from 'vant';
    
    
    Vue.use(Button)
    Vue.use(DatetimePicker)
    Vue.use(Popup)
    Vue.use(Field);

\---------完。
