javascript - setHours 和 setMinutes 不起作用 React 类组件

Question

我正在禁用时间输出。请看一下随附的图片。我已经导入setHours和setMinutes库

  state = {
    startTime: new Date(),
    time: null 
  };
  handleChange = time => {
    this.setState({
      startTime: time,
    });   
  };
render() {
      return (
        <div className="dateandtime-picker-box">
        <DatePicker
          autoFocus={false}
          placeholderText="Time"
          className="react-datepicker-wrapper"
          selected={this.state.startTime}
          onChange={time => this.handleChange(time)}
          maxTime={setHours(setMinutes(new Date(), 30), 17)}
          minTime={setHours(setMinutes(new Date(), 30), 7)}
          isClearable
          showTimeSelect
          showTimeSelectOnly
          timeIntervals={30}
          timeCaption="Time"
          dateFormat="h:mm aa"
        >
        </DatePicker>
        </div>
      )
}
