最近在做和时间段范畴相干的,预设罕用的日期范畴能够进步用户体验。能够说 antd 的组件是很不错的,然而美中不足的是,不反对预设范畴回填选中,怎么办?

在此基础上封装一下好了。

先来看下效果图:

未选中:

选中回填:

看了下渲染进去的 html 内容,用的是 Tag 实现的。那我也这么实现好了。

次要是利用 RangePickerrenderExtraFooter 进行解决。如果回填值和预设值统一,就设置选中,否则就不选中。

还有一个要害的点:就是选中预设的 tag 后,须要 敞开 日期抉择弹窗。所以还须要额定的解决 open

具体实现看上面代码:

// rangePicker.tsx 

import React, {forwardRef} from 'react'
import {Tag, DatePicker} from 'antd';
import {useState} from 'react';
import {RangePickerProps, RangePickerValue} from 'antd/lib/date-picker/interface';

const {RangePicker} = DatePicker

const Index = ({value, ranges = {}, onChange, open, format = "YYYY-MM-DD", ...props}: RangePickerProps, ref: any) => {const [val, setVal] = useState(value)
  const [show, setShow] = useState(open)

  const isDateSame = (key: string) => {const [start, end] = ranges[key] as RangePickerValue
    return val && val.length && start && end ? start.isSame(val[0]) && end.isSame(val[1]) : false
  }
  const tagCheck = (key: string) => () => {setVal(ranges[key])
    const [start, end] = ranges[key] as RangePickerValue
    onChange && onChange(ranges[key] as RangePickerValue, [start ? start.format(format as string) : '', end ? end.format(format as string) :''])
    setShow(false)
  }

  const footRanges = () => (
    <div className="range-quick-selector">
      {Object.keys(ranges).map(key => (<Tag key={key} onClick={tagCheck(key)} color={isDateSame(key) ? 'blue' : ''}>{key}</Tag>
      ))}
    </div>
  )

  const onOpenChange = (status: boolean) => {setShow(status)
  }

  const onChangeFn = (dates: RangePickerValue, dateStrings: [string, string]) => {onChange && onChange(dates, dateStrings)
    setVal(dates)
  }

  return (
    <RangePicker
      renderExtraFooter={footRanges}
      value={val}
      onChange={onChangeFn}
      onOpenChange={onOpenChange}
      open={show}
      format={format}
      {...props}
    />
  )
}

export default forwardRef(Index)

怎么用呢?原来怎么应用,当初就怎么应用:

import React, {useState} from 'react'
import moment from 'moment';
import {RangePickerValue, RangePickerPresetRange} from 'antd/lib/date-picker/interface';
import RangePicker from './rangePicker'

const ranges: {[range: string]: RangePickerPresetRange } = {'明天': [moment(), moment()],
  '昨天': [moment().subtract('days', 1), moment().subtract('days', 1)],
  '近一周': [moment().subtract('days', 7), moment()],
  '近两周': [moment().subtract('days', 14), moment()],
  '近一个月': [moment().subtract('days', 30), moment()],
  '近三个月': [moment().subtract('days', 90), moment()],
  '近半年': [moment().subtract('days', 182), moment()], // 一年的一半
  '近一年': [moment().subtract('days', 365), moment()],
  '当月': [moment().startOf('month'), moment()],
  '当季': [moment().startOf('quarter'), moment()],
  '当年': [moment().startOf('year'), moment()],
} 

const demo = () => {const [dateRange, setDateRange] = useState<RangePickerValue>([])
  
  const rangePickerChange = (dates: RangePickerValue, dateStrings: [string, string]) => {console.log({dates, dateStrings});
    setDateRange(dates)
  }

  return <RangePicker value={dateRange} onChange={rangePickerChange} ranges={ranges} />
}
