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

            var previousDate = new Date();
            previousDate.setDate(currentDate.getDate() - 1); //获取t-1天
            self.reportDate = previousDate
        }else if(type=='1'){
