强调一下我的picker-options是写在了data-return

picker-options的disabledDate后面一定要加上 => 具体看下图

pickerOptions: {

  disabledDate: (time) => {

    const startVal = new Date(this.createTimeStart);
    const endVal = new Date(this.createTimeEnd);
    return startVal.getTime() >= time.getTime() || time.getTime() >= endVal.getTime();
  },
},
