  disabledDate: (time) => {
      if (this.month) {
          let _t =  new Date(this.month),
          _f = new Date(_t.getFullYear(),_t.getMonth()+1, 1).getDate(),
          _l = new Date(_t.getFullYear(),_t.getMonth()+1, 0).getDate();
          const firstTime = new Date(this.month+'-'+_f).getTime();
          const lastTime = new Date(this.month+'-'+_l).getTime();
          return time.getTime() < firstTime || time.getTime() > lastTime
        }
    }
},

2、只允许选择today往后的日期，不含当天

pickerOptions: {
    disabledDate: (time) => {
        let _t =  new Date().getTime();
        return time.getTime() < _t; // time.getTime() < Date.now()
    }
},

3、只允许选择today往前的日期，含当天

pickerOptions: {
    disabledDate: (time) => {
        let _t =  new Date().getTime();
        return time.getTime() > _t
    }
},

4、只允许选择当前日期往前2周，today-14，含当天

pickerOptions: {
  disabledDate: (time) => {
      let _t =  new Date().getTime();
      let prev = new Date(new Date(_t).getTime() - (14 * 24 * 3600 * 1000)).getTime();
      return time.getTime() > _t || time.getTime() < prev;
    }
},

5、只能选择3年前的日期

pickerOptions: {
    disabledDate: (time) => {
        let _t =  new Date().getTime();
        let three =  _t - (1000 * 3600 * 24 * 365 * 3);
        return time.getTime() > three;
    }
},

6、只能选择3年后的日期

pickerOptions: {
    disabledDate: (time) => {
        let _t =  new Date().getTime();
        let three =  _t + (1000 * 3600 * 24 * 365 * 3);
        return time.getTime() < three;
    }
},

7、选择区间在[当前日期往前一年，当前日期往后一年]

pickerOptions: {
 disabledDate: (time) => {
     let _t =  new Date().getTime();
     let prevY =  _t - (1000 * 3600 * 24 * 365 * 1);
     let nextY = _t + (1000 * 3600 * 24 * 365 * 1)
     return time.getTime() < prevY || time.getTime() > nextY;
 }
},

8、选择区间在[当前年1月1号，当前年12月31号]

pickerOptions1: {
    disabledDate: (time) => {
        let _t =  new Date();
        let _f = new Date(_t.getFullYear(),0, 1).getTime();
        let _l = new Date(_t.getFullYear(),12, 0).getTime();
        return time.getTime() < _f || time.getTime() > _l;
    }
},

9、在指定区间内选择，如["2023-03-01","2023-04-18"]，含后不含前

pickerOptions: {
    disabledDate: (time) => {
        let _f = new Date("2023-03-01").getTime();
        let _l = new Date("2023-04-18").getTime();
        return time.getTime() < _f || time.getTime() > _l
    }
},

10、限制在一个月之内

pickerOptions: {
    disabledDate: (time) => {
        let one = 30*24*3600*1000, today = new Date().getTime();
        let _p = today - one;
        let _n = today + one;
        return time.getTime() < _p || time.getTime() > _n
    }
},

11、禁止选择周末

pickerOptions: {
