html

<yto-form-item label="  ">
          <div>
              <yto-radio-group v-model="reportDateType" size="mini" @change="handleChangeReport('0')" class="all-time-position">
                  <yto-radio-button label="date">日</yto-radio-button>
                  <yto-radio-button label="week">周</yto-radio-button>
                  <yto-radio-button label="month">月</yto-radio-button>

                :format="reportDateType==='week'?'yyyy 第 WW 周':null" 
                :placeholder="reportDateType==='date'?'请选择日':reportDateType==='week'?'请选择周':reportDateType==='month'?'请选择月': ''"  
                class="statistic-analysis-report-spot-time-select" @change="handleChangeReport()">
              </yto-date-picker>
          </div>
        </yto-form-item>

这个js里面写dateFormat 方法

import { dateFormat } from '@/util/util.js';

方法如下
export function dateFormat(date, fmt) {
    var o = {
        'M+': date.getMonth() + 1, // 月份
        'd+': date.getDate(), // 日
        'h+': date.getHours(), // 小时
        'm+': date.getMinutes(), // 分
        's+': date.getSeconds(), // 秒
        'q+': Math.floor((date.getMonth() + 3) / 3), // 季度
        'S': date.getMilliseconds() // 毫秒
    };
    if (/(y+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, (date.getFullYear() + '').substr(4 - RegExp.$1.length));
    }
    for (var k in o) {
        if (new RegExp('(' + k + ')').test(fmt)) {
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? (o[k]) : (('00' + o[k]).substr(('' + o[k]).length)));
        }
    }
    return fmt;
}

data里面定义变量

//查询列表
      listForm: {
        startTime:'', //开始时间
        endTime:'', //结束时间
      },
      activeName: 'package_timeliness',
      reportDateType: 'date',
      reportDate: null,
      timeObj:{}, //存日,周,月时间的
      pickerOptions: {
          disabledDate(date) {
            // 获取当前日期
            var currentDate = new Date();
            // 获取前一天日期
            var previousDate = new Date();
            previousDate.setDate(currentDate.getDate() - 1); //获取t-1天
              return date.getTime() > previousDate; //禁用
          }
          },

created

created() {
    this.$nextTick(()=>{
      this.handleChangeReport('0')//默认查t-1天数据
      this.getList();//列表
    })
  },

methods

            var currentDate = new Date();
            // 获取前一天日期
            var previousDate = new Date();
            previousDate.setDate(currentDate.getDate() - 1); //获取t-1天
            self.reportDate = previousDate
        }else if(type=='1'){
            
        }
        self.timeDifferenceReport(self.reportDate, self.reportDateType);
    },
    timeDifferenceReport() {
        let time = new Date(dateFormat(this.reportDate, "yyyy-MM-dd")); // 可入参指定时间

列表
