Form 表单

由输入框、选择器、单选框、多选框等控件组成，用以收集、校验、提交数据。

import { Form, FormItem } from 'uiw';
// or
import { Form, FormItem } from '@uiw/react-form';

基本用法

import React, { useState, useRef } from "react";
import { Form, Input, Row, Col, Slider, Button, Notify } from 'uiw';

export default function Demo() {
  const form = useRef()

  const onSubmit = () => {
    form.current.onSubmit()
  }
  const resetForm = () => {
    form.current.resetForm()
  }
  const getFieldValues = () => {
    console.log('getFieldValues', form.current.getFieldValues())
  }

  const setFieldValue=()=>{
    form.current.setFieldValue('name','UIW')
  }

  return (
    <div>
      <Form
        ref={form}
        onChange={({ initial, current }) => {
          console.log('onChange', initial, current);
        }}
        onSubmit={({ initial, current }) => {
          if (current.name === initial.name) {
            Notify.error({
              title: '提交失败！',
              description: `表单提交内容为空！`,
            });
          } else {
            Notify.success({
              title: '提交成功！',
              description: `姓名为：${current.name}，提交完成，将自动填充初始化值！`,
            });
          }
        }}
        fields={{
          name: {
            label: '姓名',
            children: <Input placeholder="请输入姓名" />
          },
        }}
      >
        {({ fields, state, canSubmit }) => {
          return (
            <div>
              <Row>
                <Col style={{ maxWidth: 300 }}>{fields.name}</Col>
              </Row>
              <Row>
                <Col>
                  <Button disabled={!canSubmit()} type="primary" htmlType="submit">提交</Button>
                </Col>
              </Row>
              <Row>
                <Col>
                  {JSON.stringify(state.current)}
                </Col>
              </Row>
            </div>
          )
        }}
      </Form>
      <Button type="primary" onClick={onSubmit} >submit</Button>
      <Button type="primary" onClick={resetForm}>resetForm</Button>
      <Button type="primary" onClick={getFieldValues}>getValues</Button>
      <Button type="primary" onClick={setFieldValue}>setFieldValue</Button>
    </div>
  )
}

自定义校验

一般校验可不需引入外部包解决，如果遇到大型工程表单比较多的地方推荐使用 jquense/yup

import React from 'react';
import { Form, Input, Notify, Checkbox, Switch, RadioGroup, Radio, Textarea, Row, Col, Button, Select, SearchSelect } from 'uiw';

export default function Demo() {
  return(
    <Form
      onSubmit={({initial, current}) => {
        const errorObj = {};
        if (current.userName.startsWith('u')) {
          errorObj.userName = `姓名 ${current.userName} 不能以 ‘u’ 开头`;
        }
        if (!current.checkboxOne) {
          errorObj.checkboxOne = '一个多选条件 为必填';
        }
        if (!current.terms) {
          errorObj.terms = '必须统一服务条款';
        }
        if(Object.keys(errorObj).length > 0) {
          const err = new Error();
          err.filed = errorObj;
          throw err;
        }
        Notify.success({
          title: '提交成功！',
          description: `姓名为：${current.userName}，提交完成，将自动填充初始化值！`,
        });
      }}
      onSubmitError={(error) => {
        if (error.filed) {
          return { ...error.filed };
        }
        return null;
      }}
      fields={{
        userName: {
          initialValue: 'uiw',
          label: '姓名',
          children: <Input type="text" />,
          help: '以“u”开头的名字将在此处显示错误信息'
        },
        age: {
          initialValue: '9',
          label: '年龄',
          children: <Input type="number" />

      </Form>
    </div>
  )
}

自定义控件应用

下面实例是在 <Form /> 表单组件中，应用自定义 <CustomSelect /> 控件组件。

⚠️ 注意，自定义控件需要两个必要的 props 参数，value 和 onChange

value 用于值传递，
onChange(value) 用于值变更需要执行的回调函数，回调函数第一个参数必须是 value。

import React from 'react';
import { Form, Row, Col, Dropdown, Menu, Icon, Button, Notify } from 'uiw';

// 自定义组件
function CustomSelect(props) {
  const { option = [], onChange } = props;
  const [value, setValue] = React.useState(props.value);
  const [isOpen, setIsOpen] = React.useState(false);
