当我在 webpack-dev-server 中呈现它时,日历不会在点击时呈现。
如果我尝试手动更改日期,则会收到错误消息:
DateSelection.js?f52c:25 Uncaught TypeError: Cannot read property 'calendarFocus' of null
SingleDatePicker 似乎工作得很好,但不是 DateRangePicker。我该怎么做才能在点击时正确呈现日历?
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import moment from 'moment';
import { DateRangePicker } from 'react-dates';
import 'react-dates/initialize';
import 'react-dates/lib/css/_datepicker.css';
class DateSelection extends Component {
constructor(props) {
super(props);
this.state = {
startDate: moment(),
endDate: moment(),
calendarFocus: 'startDate',
}
this.onDatesChange = this.onDatesChange.bind(this);
this.onFocusChange = this.onFocusChange.bind(this);
this.onSubmit = this.onSubmit.bind(this);
};
onDatesChange({ startDate, endDate }) {
this.setState(() => ({ startDate, endDate }));
};
onFocusChange({ calendarFocus }) {
this.setState(() => ({ calendarFocus }));
};
onSubmit(e) {
e.preventDefault();
console.log(this.state);
};
render() {
return (
<form onSubmit={this.onSubmit}>
<DateRangePicker
startDate={this.state.startDate}
startDateId="startDate"
endDate={this.state.endDate}
endDateId="endDate"
onDatesChange={this.onDatesChange}
focusedInput={this.state.calendarFocus}
onFocusChange={this.onFocusChange}
/>
<br/>
<input type="submit" value="Submit" />
</form>
);
}
};
ReactDOM.render((
<DateSelection/>
), document.getElementById('root'));

另外,顺便说一句,我似乎找不到当前的 react-dates 文档。很多地方都将我链接到这本故事书,但似乎缺少一些信息。例如,此处的描述列是空白的。
