javascript - 如何使用 Material ui reactjs 禁用从今天开始的过去日期？

Question

我正在使用 React Material UI 创建日期范围选择器。此功能背后的我的逻辑是选择所需日期，如果选择了所需日期，则禁用所选日期的所有过去日期。这个react material ui怎么实现？

这是我的代码，

import React from 'react';
import {render} from 'react-dom';
import DatePicker from 'material-ui/DatePicker';

function disablePrevDates(date) {
  return date.getDay() === 0;
}

class App extends React.Component {
    render() {
        return (
            <div>
                <DatePicker hintText="Check-in" shouldDisableDate={disablePrevDates} />
            </div>
        )
    }
}

export default App;

这里是:

import React from 'react';
import DatePicker from 'material-ui/DatePicker';

function disablePrevDates(startDate) {
  const startSeconds = Date.parse(startDate);
  return (date) => {
    return Date.parse(date) < startSeconds;
  }
}

class App extends React.Component {
    
    render() {
        const startDate = new Date();
//      or:
//      const startDate = new Date('December 20, 2016');
//      const startDate = this.state.firstDate;
      
        return (
            <div>
                <DatePicker 
                  hintText="Check-in" 
                  shouldDisableDate={disablePrevDates(startDate)}
                />
            </div>
        )
    }
}

export default App;
