taro 中使用

安装

npm install @carefrees/form-utils-react-taro # yarn add @carefrees/form-utils-react-taro # pnpm add @carefrees/form-utils-react-taro

使用

基本使用

import { Form, FormItem } from '@carefrees/form-utils-react-taro';
import React, { useState } from 'react';
import { View, Button, Input } from '@tarojs/components';

const Demo = () => {
  const [formData] = useState({ name: '张三', age: 18 });
  const form = useForm();

  const onSubmit = async () => {
    try {
      console.log(form);
      const result = await form.validate();
      console.log(result);
    } catch (error) {
      console.log(error);
    }
  };

  return (
    <Form formData={formData} form={form}>
      <FormItem trigger="onInput" rules={[{ required: true, message: '必填' }]} name="name" label="name">
        <Input style={{ width: '100%' }} placeholder="请输入" />
      </FormItem>
      <FormItem trigger="onInput" name="age" label="age">
        <Input style={{ width: '100%' }} placeholder="请输入" />
      </FormItem>
      <Button onClick={onSubmit}>验😁😝证</Button>
    </Form>
  );
};

控制隐藏

import { Form, FormItem, FormHideItem } from '@carefrees/form-utils-react';
import React, { useState } from 'react';
import { View, Button, Input } from '@tarojs/components';

const Demo = () => {
  const [formData] = useState({ name: '张三', age: 18 });
  const form = useForm();

  const onSubmit = async () => {
    try {
      console.log(form);
      const result = await form.validate();
      console.log(result);
    } catch (error) {
      console.log(error);
    }
  };

  const onValuesChange = (item: any) => {
    console.log('item', item);
    if (Reflect.has(item, 'age')) {
      if (item.age === '18') {
        form.updatedFieldHideValue({ address: false });
      } else {
        form.updatedFieldHideValue({ address: true });
      }
    }
  };

  return (
    <Form formData={formData} form={form} onValuesChange={onValuesChange} hideData={{ address: true }}>
      <FormItem rules={[{ required: true, message: '必填' }]} name="name" label="name">
        <Input style={{ width: '100%' }} placeholder="请输入" />
      </FormItem>
      <FormItem name="age" label="age">
        <Input style={{ width: '100%' }} placeholder="请输入18,显示address表单项" />
      </FormItem>
      <FormHideItem name="address" label="address">
        <Input style={{ width: '100%' }} placeholder="请输入" />
      </FormHideItem>
      <Button onClick={onSubmit}>验😁😝证</Button>
    </Form>
  );
};

表单字段监听

import { Form, FormItem, useWatch } from '@carefrees/form-utils-react';
import React, { useState } from 'react';
import { View, Button, Input } from '@tarojs/components';

// 子节点
const Child = () => {
  // 第一次监听可以获取到值
  const [value] = useWatch('name');
  return <View>name值：{value}</View>;
};

const Demo = () => {
  const [formData] = useState({ name: '张三', age: 18 });
  const form = useForm();

  // 在表单包裹内,第一次监听获取不到值
  const [age] = useWatch('age', form);
  console.log(age);

  const onSubmit = async () => {
    try {
      console.log(form);
      const result = await form.validate();
      console.log(result);
    } catch (error) {
      console.log(error);
    }
  };

  return (
    <Form formData={formData} form={form}>
      <FormItem rules={[{ required: true, message: '必填' }]} name="name" label="name">
        <Input style={{ width: '100%' }} placeholder="请输入" />
      </FormItem>
      <FormItem name="age" label="age">
        <Input style={{ width: '100%' }} placeholder="请输入" />
      </FormItem>
      <Child />
      <Button onClick={onSubmit}>验😁😝证</Button>
    </Form>
  );
};
