可以设置 disabledDate 方法,来约束开始和结束日期。

import { DatePicker } from 'antd';

const DateRange = React.createClass({
  getInitialState() {
    return {
      startValue: null,
      endValue: null,
    };
  },
  disabledStartDate(startValue) {
    if (!startValue || !this.state.endValue) {
      return false;
    }
    return startValue.getTime() >= this.state.endValue.getTime();
  },
  disabledEndDate(endValue) {
    if (!endValue || !this.state.startValue) {
      return false;
    }
    return endValue.getTime() <= this.state.startValue.getTime();
  },
  onChange(field, value) {
    console.log(field, 'change', value);
    this.setState({
      [field]: value,
    });
  },
  onStartChange(value) {
    this.onChange('startValue', value);
  },
  onEndChange(value) {
    this.onChange('endValue', value);
  },
  render() {
    return (
      <div>
        <DatePicker disabledDate={this.disabledStartDate}
          value={this.state.startValue}
          placeholder="开始日期"
          onChange={this.onStartChange} />
        <DatePicker disabledDate={this.disabledEndDate}
          value={this.state.endValue}
          placeholder="结束日期"
          onChange={this.onEndChange} />
      </div>
    );
  },
});

ReactDOM.render(
  <DateRange />
, mountNode);
