DatePicker日期选择框

输入或选择日期的控件。

何时使用

当用户需要输入一个日期，可以点击标准输入框，弹出日期面板进行选择。

代码演示

基本

最简单的用法，在浮层中可以选择或者输入日期。

import { DatePicker } from 'choerodon-ui';
const { MonthPicker, RangePicker, WeekPicker } = DatePicker;
function onChange(date, dateString) {
  console.log(date, dateString);
}
ReactDOM.render(
  <div>
    <DatePicker onChange={onChange} label="日期框" />
    <br />
    <MonthPicker onChange={onChange} placeholder="Select month" />
    <br />
    <RangePicker onChange={onChange} label="日期范围" />
    <br />
    <WeekPicker onChange={onChange} placeholder="Select week" label="选择周" />
  </div>,
  mountNode,
);

三种大小

三种大小的输入框，若不设置，则为 default。

import { DatePicker, Radio } from 'choerodon-ui';
const { MonthPicker, RangePicker, WeekPicker } = DatePicker;
class PickerSizesDemo extends React.Component {
  state = {
    size: 'default',
  };
  handleSizeChange = e => {
    this.setState({ size: e.target.value });
  };
  render() {
    const { size } = this.state;
    return (
      <div>
        <Radio.Group value={size} onChange={this.handleSizeChange}>
          <Radio.Button value="large">Large</Radio.Button>
          <Radio.Button value="default">Default</Radio.Button>
          <Radio.Button value="small">Small</Radio.Button>
        </Radio.Group>
        <br />
        <br />
        <DatePicker size={size} />
        <br />
        <MonthPicker size={size} placeholder="Select Month" />
        <br />
        <RangePicker size={size} />
        <br />
        <WeekPicker size={size} placeholder="Select Week" />
      </div>
    );
  }
}
ReactDOM.render(<PickerSizesDemo />, mountNode);

禁用

选择框的不可用状态。

import { DatePicker } from 'choerodon-ui';
import moment from 'moment';
const { MonthPicker, RangePicker } = DatePicker;
const dateFormat = 'YYYY-MM-DD';
ReactDOM.render(
  <div>
    <DatePicker defaultValue={moment('2015-06-06', dateFormat)} disabled />
    <br />
    <MonthPicker defaultValue={moment('2015-06', 'YYYY-MM')} disabled />
    <br />
    <RangePicker
      defaultValue={[moment('2015-06-06', dateFormat), moment('2015-06-06', dateFormat)]}
      disabled
    />
  </div>,
  mountNode,
);

自定义日期范围选择

当 RangePicker 无法满足业务需求时，可以使用两个 DatePicker 实现类似的功能。

• 通过设置 disabledDate 方法，来约束开始和结束日期。

• 通过 open onOpenChange 来优化交互。

import { DatePicker } from 'choerodon-ui';
class DateRange extends React.Component {
  state = {
    startValue: null,
    endValue: null,
    endOpen: false,
  };
  disabledStartDate = (startValue) => {
    const endValue = this.state.endValue;
    if (!startValue || !endValue) {
      return false;
    }
    return startValue.valueOf() > endValue.valueOf();
  }
  disabledEndDate = (endValue) => {
    const startValue = this.state.startValue;
    if (!endValue || !startValue) {
      return false;
    }
    return endValue.valueOf() <= startValue.valueOf();
  }
  onChange = (field, value) => {
    this.setState({
      [field]: value,
    });
  }
  onStartChange = (value) => {
    this.onChange('startValue', value);
  }
  onEndChange = (value) => {
    this.onChange('endValue', value);
  }
  handleStartOpenChange = (open) => {
    if (!open) {
      this.setState({ endOpen: true });
    }
  }
  handleEndOpenChange = (open) => {
    this.setState({ endOpen: open });
  }
  render() {
    const { startValue, endValue, endOpen } = this.state;
    return (
      <div>
        <DatePicker
          disabledDate={this.disabledStartDate}
          showTime
          format="YYYY-MM-DD HH:mm:ss"
          value={startValue}
          placeholder="Start"
          onChange={this.onStartChange}
          onOpenChange={this.handleStartOpenChange}
        />
        <DatePicker
          disabledDate={this.disabledEndDate}
          showTime
          format="YYYY-MM-DD HH:mm:ss"
          value={endValue}
          placeholder="End"
          onChange={this.onEndChange}
          open={endOpen}
          onOpenChange={this.handleEndOpenChange}
        />
      </div>
    );
  }
}
ReactDOM.render(<DateRange />, mountNode);

额外的页脚

在浮层中加入额外的页脚，以满足某些定制信息的需求。

import { DatePicker } from 'choerodon-ui';
const { RangePicker, MonthPicker } = DatePicker;
ReactDOM.render(
  <div>
    <DatePicker renderExtraFooter={() => 'extra footer'} />
    <DatePicker renderExtraFooter={() => 'extra footer'} showTime />
    <RangePicker renderExtraFooter={() => 'extra footer'} />
    <RangePicker renderExtraFooter={() => 'extra footer'} showTime />
    <MonthPicker renderExtraFooter={() => 'extra footer'} placeholder="Select month" />
  </div>,
  mountNode,
);

定制日期单元格

使用 dateRender 可以自定义日期单元格的内容和样式。

import { DatePicker } from 'choerodon-ui';
const { RangePicker } = DatePicker;
ReactDOM.render(
  <div>
    <DatePicker
      dateRender={current => {
        const style = {};
        if (current.date() === 1) {
          style.border = '1px solid #1890ff';
          style.borderRadius = '50%';
        }
        return (
          <div className="c7n-calendar-date" style={style}>
            {current.date()}
          </div>
        );
      }}
    />
    <RangePicker
      dateRender={current => {
        const style = {};
        if (current.date() === 1) {
          style.border = '1px solid #1890ff';
          style.borderRadius = '50%';
        }
        return (
          <div className="c7n-calendar-date" style={style}>
            {current.date()}
          </div>
        );
      }}
    />
  </div>,
  mountNode,
);

日期格式

使用 format 属性，可以自定义日期显示格式。

import { DatePicker } from 'choerodon-ui';
import moment from 'moment';
const { MonthPicker, RangePicker } = DatePicker;
const dateFormat = 'YYYY/MM/DD';
const monthFormat = 'YYYY/MM';
ReactDOM.render(
  <div>
    <DatePicker defaultValue={moment('2015/01/01', dateFormat)} format={dateFormat} />
    <br />
    <MonthPicker defaultValue={moment('2015/01', monthFormat)} format={monthFormat} />
    <br />
    <RangePicker
      defaultValue={[moment('2015/01/01', dateFormat), moment('2015/01/01', dateFormat)]}
      format={dateFormat}
    />
  </div>,
  mountNode,
);

日期时间选择

增加选择时间功能，当 showTime 为一个对象时，其属性会传递给内建的 TimePicker。

import { DatePicker } from 'choerodon-ui';
const { RangePicker } = DatePicker;
function onChange(value, dateString) {
  console.log('Selected Time: ', value);
  console.log('Formatted Selected Time: ', dateString);
}
function onOk(value) {
  console.log('onOk: ', value);
}
ReactDOM.render(
  <div>
    <DatePicker
      showTime
      format="YYYY-MM-DD HH:mm:ss"
      placeholder="Select Time"
      onChange={onChange}
      onOk={onOk}
    />
    <br />
    <RangePicker
      showTime={{ format: 'HH:mm' }}
      format="YYYY-MM-DD HH:mm"
      placeholder={['Start Time', 'End Time']}
      onChange={onChange}
      onOk={onOk}
    />
  </div>,
  mountNode,
);

不可选择日期和时间

可用 disabledDate 和 disabledTime 分别禁止选择部分日期和时间，其中 disabledTime 需要和 showTime 一起使用。

import moment from 'moment';
import { DatePicker } from 'choerodon-ui';
const { MonthPicker, RangePicker } = DatePicker;
function range(start, end) {
  const result = [];
  for (let i = start; i < end; i++) {
    result.push(i);
  }
  return result;
}
function disabledDate(current) {
  // Can not select days before today and today
  return current && current < moment().endOf('day');
}
function disabledDateTime() {
  return {
    disabledHours: () => range(0, 24).splice(4, 20),
    disabledMinutes: () => range(30, 60),
    disabledSeconds: () => [55, 56],
  };
}
function disabledRangeTime(_, type) {
  if (type === 'start') {
    return {
      disabledHours: () => range(0, 60).splice(4, 20),
      disabledMinutes: () => range(30, 60),
      disabledSeconds: () => [55, 56],
    };
  }
  return {
    disabledHours: () => range(0, 60).splice(20, 4),
    disabledMinutes: () => range(0, 31),
    disabledSeconds: () => [55, 56],
  };
}
ReactDOM.render(
  <div>
    <DatePicker
      format="YYYY-MM-DD HH:mm:ss"
      disabledDate={disabledDate}
      disabledTime={disabledDateTime}
      showTime={{ defaultValue: moment('00:00:00', 'HH:mm:ss') }}
    />
    <br />
    <MonthPicker disabledDate={disabledDate} placeholder="Select month" />
    <br />
    <RangePicker
      disabledDate={disabledDate}
      disabledTime={disabledRangeTime}
      showTime={{
        hideDisabledOptions: true,
        defaultValue: [moment('00:00:00', 'HH:mm:ss'), moment('11:59:59', 'HH:mm:ss')],
      }}
      format="YYYY-MM-DD HH:mm:ss"
    />
  </div>,
  mountNode,
);

预设范围

RangePicker 可以设置常用的 预设范围 提高用户体验。

import { DatePicker } from 'choerodon-ui';
import moment from 'moment';
const RangePicker = DatePicker.RangePicker;
function onChange(dates, dateStrings) {
  console.log('From: ', dates[0], ', to: ', dates[1]);
  console.log('From: ', dateStrings[0], ', to: ', dateStrings[1]);
}
ReactDOM.render(
  <div>
    <RangePicker
      ranges={{ Today: [moment(), moment()], 'This Month': [moment(), moment().endOf('month')] }}
      onChange={onChange}
    />
    <br />
    <RangePicker
      ranges={{ Today: [moment(), moment()], 'This Month': [moment(), moment().endOf('month')] }}
      showTime
      format="YYYY/MM/DD HH:mm:ss"
      onChange={onChange}
    />
  </div>,
  mountNode,
);

受控面板

通过组合 mode 与 onPanelChange 控制要展示的面板。

import { DatePicker } from 'choerodon-ui';
const { RangePicker } = DatePicker;
class ControlledDatePicker extends React.Component {
  state = { mode: 'time' };
  handleOpenChange = open => {
    if (open) {
      this.setState({ mode: 'time' });
    }
  };
  handlePanelChange = (value, mode) => {
    this.setState({ mode });
  };
  render() {
    return (
      <DatePicker
        mode={this.state.mode}
        showTime
        onOpenChange={this.handleOpenChange}
        onPanelChange={this.handlePanelChange}
      />
    );
  }
}
class ControlledRangePicker extends React.Component {
  state = {
    mode: ['month', 'month'],
    value: [],
  };
  handlePanelChange = (value, mode) => {
    this.setState({
      value,
      mode: [mode[0] === 'date' ? 'month' : mode[0], mode[1] === 'date' ? 'month' : mode[1]],
    });
  };
  render() {
    const { value, mode } = this.state;
    return (
      <RangePicker
        placeholder={['Start month', 'End month']}
        format="YYYY-MM"
        value={value}
        mode={mode}
        onPanelChange={this.handlePanelChange}
      />
    );
  }
}
ReactDOM.render(
  <div>
    <ControlledDatePicker />
    <br />
    <ControlledRangePicker />
  </div>,
  mountNode,
);

API

日期类组件包括以下四种形式。

• DatePicker

• MonthPicker

• RangePicker

• WeekPicker

注意：DatePicker、MonthPicker、RangePicker、WeekPicker 部分 locale 是从 value 中读取，所以请先正确设置 moment 的 locale。

// 默认语言为 en-US，如果你需要设置其他语言，推荐在入口文件全局设置 locale
// import moment from 'moment';
// import 'moment/locale/zh-cn';
// moment.locale('zh-cn');
<DatePicker defaultValue={moment('2015-01-01', 'YYYY-MM-DD')} />
