Package Exports

@uiw/react-form
@uiw/react-form/cjs/index.js
@uiw/react-form/esm/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@uiw/react-form) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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';

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>
  )
}
export default Demo

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 } from 'uiw';

const Demo = () => (
  <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;

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);

  React.useEffect(() => {
    if (value !== props.value) {
      setValue(props.value);
    }
  }, [props.value]);
  const label = option.find(item => value === item.value);
  return (
    <Dropdown
      trigger="click"
      onVisibleChange={(open) => setIsOpen(open)}
      isOpen={isOpen}
      menu={
        <Menu bordered style={{ minWidth: 120 }}>
          {option.map((item, idx) => (
            <Menu.Item active={value === item.value} key={idx} text={item.label}
              onClick={() => {
                setValue(item.value);
                setIsOpen(false)
                onChange && onChange(item.value);
              }}
            />
          ))}
        </Menu>
      }
    >
      <Button
        style={{
          boxShadow: 'inset 0 0 0 1px rgba(16, 22, 26, 0.2), inset 0 -1px 0 rgba(16, 22, 26, 0.1)'
        }}
        type="link"
      >
        {label.label}<Icon type={isOpen ? 'up' : 'down'} />
      </Button>
    </Dropdown>
  );
