需求:可选择的时间大于当前时间,不符合条件的全部禁用
以下实现方式可精确到年、月、日、时、分、秒
HTML

<el-form-item label="盘点开始时间" prop="checkStartTime">
      <el-date-picker
        type="datetime"
        placeholder="请选择开始时间"
        style="width: 100%"
        clearable
        format="yyyy-MM-dd HH:mm:ss"
        :picker-options="pickerOptions"
        v-model="inventoryEdit.checkStartTime"
      ></el-date-picker>
 </el-form-item>

data里

// 选择开始时间大于等于当前时间
      pickerOptions: {
        disabledDate(time) {
          const dateTime = new Date();
          const startDateTime = dateTime.setDate(dateTime.getDate() - 1);
          const endDateTime = dateTime.setDate(dateTime.getDate() + 30000); //30000为当前日期之后多少天
          return (
            time.getTime() < new Date(startDateTime).getTime() ||
            time.getTime() > new Date(endDateTime).getTime()
          );
        },
        selectableRange:
        //setMinutes,getMinutes限制分 , 年、月、日、时、分、秒同理,+1为数字区间
        //重点就在这个set get, 渔给了, 鱼自己捕吧
          this.parseTime(new Date().setMinutes(new Date().getMinutes() + 1),"{hh}:{ii}:{ss}") + "- 23:59:00",
      },
      //this.parseTime为封装的方法在下面贴出来了

this.parseTime

// 日期格式化
export function parseTime(time, pattern) {
    if (arguments.length === 0 || !time) {
        return null
    }
    const format = pattern || '{y}-{m}-{d} {h}:{i}:{s}'
    let date
    if (typeof time === 'object') {
        date = time
    } else {
        if ((typeof time === 'string') && (/^[0-9]+$/.test(time))) {
            time = parseInt(time)
        } else if (typeof time === 'string') {
            time = time.replace(new RegExp(/-/gm), '/');
        }
        if ((typeof time === 'number') && (time.toString().length === 10)) {
            time = time * 1000
        }
        date = new Date(time)
    }
    const formatObj = {
        y: date.getFullYear(),
        m: date.getMonth() + 1,
        d: date.getDate(),
        h: date.getHours(),
        i: date.getMinutes(),
        s: date.getSeconds(),
        a: date.getDay()
    }
    const time_str = format.replace(/{(y|m|d|h|i|s|a)+}/g, (result, key) => {
        let value = formatObj[key]
        // Note: getDay() returns 0 on Sunday
        if (key === 'a') { return ['日', '一', '二', '三', '四', '五', '六'][value] }
        if (result.length > 0 && value < 10) {
            value = '0' + value
        }
        return value || 0
    })
    return time_str
}
