React实现复杂搜索表单的展开收起功能

给时间时间，让过去过去。

上节我们写过了【搜索】表单，以及查询、重置功能。本节对于需要展开收起效果的查询表单 进行概述，主要涉及前端样式知识。

样式效果如下：

 思路：在Search组件中定义两个组件renderAdvancedForm，renderSimpleForm,其中renderSimpleForm中只有五个查询选项，而在renderAdvancedForm包含所有的搜索选项。点击'展开‘'收起‘按钮调用onClick={toggleForm}切换form显示样式即可。

1. 写renderSimpleForm和renderAdvancedForm

使用Col和Row进行分行分块，并注意为展开按钮添加点击事件。

 const renderSimpleForm = useMemo(() => {
    const { getFieldDecorator } = form
    const { query } = getLocation()
    return (
      <Form layout="inline">
        <Row>
          <Col md={4} sm={24}>
            <FormItem label="">...</FormItem>
          </Col>
          <Col md={4} sm={24}>
            <FormItem label="">...</FormItem>
          </Col>
          <Col md={4} sm={24}>
            <FormItem label="">...</FormItem>
          </Col>
          <Col md={4} sm={24}>
            <FormItem label="">...</FormItem>
          </Col>
          <Col md={4} sm={24}>
            <FormItem label="">...</FormItem>
          </Col>
          <Col md={4} sm={24} style={{ textAlign: 'right' }}>
            <a
              onClick={toggleForm}
              style={{ marginRight: '15px' }}
              className={styles.a}
            >
              展开 <Icon type="down" />
            </a>
            <Button onClick={handleSearch} className={'searchBtn'}>
              <img src={search} alt="" />
              查询
            </Button>
            <Button onClick={handleFormReset} className={'resetBtn'}>
              <img src={reset} alt="" />
              重置
            </Button>
          </Col>
        </Row>
      </Form>
    )
  }, [form, handleFormReset, handleSearch, toggleForm])

同理，需要使用Rol和Row设置两行，并在对应位置空出收起按钮，为收起按钮添加点击函数

const renderAdvancedForm = useMemo(() => {
    const { getFieldDecorator, getFieldValue } = form
    const { query } = getLocation()
    return (
      <Form layout="inline">
        <Row style={{ marginBottom: '20px' }}>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
          <Col md={4} sm={24} style={{ textAlign: 'right' }}>
            <a
              onClick={toggleForm}
              style={{ marginRight: '15px' }}
              className={styles.a}
            >
              收起 <Icon type="up" />
            </a>
            <Button onClick={handleSearch} className={'searchBtn'}>
              <img src={search} alt="" />
              查询
            </Button>
            <Button onClick={handleFormReset} className={'resetBtn'}>
              <img src={reset} alt="" />
              重置
            </Button>
          </Col>
        </Row>
        <Row>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
          <Col md={4} sm={24}><FormItem label="">...</FormItem></Col>
        </Row>
      </Form>
    )
  }, [form, handleFormReset, handleSearch, time1, time2, toggleForm])

2.添加toggleForm函数实现‘展开'‘收起'切换

const toggleForm = useCallback(() => {
    setExpandForm(!expandForm)
  }, [expandForm])

3.在search组件中按情况渲染表单效果

return (
    <Card bordered={false}>
      <div className={styles.search}>
        {expandForm ? renderAdvancedForm : renderSimpleForm}
      </div>
    </Card>
  )

4.附全部search组件代码

const Search: any = Form.create()(function({ form, init }: any) {
  const { validateFields } = form
  const [expandForm, setExpandForm] = useState(false)
  const [time11, settime11] = useState('')
  const [time21, settime21] = useState('')
  const [time1, settime1] = useState(moment().format('YYYY-MM-DD'))
  const [time2, settime2] = useState(moment().format('YYYY-MM-DD'))
  const handleSearch = useCallback(() => {
    validateFields((err: any, data: any) => {
      pushPath({
        query: {
          ...data,
          pageNum: 1,
          orderTimeStart: time11,
          orderTimeEnd: time21,
          orderNumber: data.orderNumber.replace(/\s+/g, ''),
          experimentName: data.experimentName.replace(/\s+/g, ''),
          userName: data.userName.replace(/\s+/g, ''),
          mobile: data.mobile.replace(/\s+/g, ''),
          priceLow: data.priceLow.replace(/\s+/g, ''),
          priceHigh: data.priceHigh.replace(/\s+/g, '')
        }
      })
      init()
    })
  }, [init, time11, time21, validateFields])
  const handleFormReset = useCallback(() => {
    clearPath()
    pushPath({
      query: { pageSize: 10, pageNum: 1 }
    })
    init()
    form.resetFields()
  }, [form, init])
  const toggleForm = useCallback(() => {
    setExpandForm(!expandForm)
  }, [expandForm])
  const renderSimpleForm = useMemo(() => {
    const { getFieldDecorator } = form
    const { query } = getLocation()
    return (
      <Form layout="inline">
        <Row>
          <Col md={4} sm={24}>
            <FormItem label="">
              {getFieldDecorator('orderNumber', {
                initialValue: query.name || ''
              })(<Input placeholder="需求编号" />)}
            </FormItem>
          </Col>
          <Col md={4} sm={24}>
            <FormItem label="">
              {getFieldDecorator('experimentName', {
                initialValue: query.name || ''
              })(<Input placeholder="需求名称" />)}
            </FormItem>
