React 供应商选择组件 - 使用Ant Design渲染Select并与父组件Form同步数据

1、安装Ant Design的相关依赖：

shell 复制代码

npm install antd @ant-design/icons

2、编写SupplierSelect组件的代码如下：

javascript 复制代码

import React, { useEffect, useState } from 'react';
import { Select } from 'antd';
import axios from 'axios';

const { Option } = Select;

const SupplierSelect = ({ value, onChange }) => {
  const [data, setData] = useState([]);

  useEffect(() => {
    fetchData();
  }, []);

  const fetchData = async () => {
    try {
      const response = await axios.get('https://api.example.com/suppliers');
      setData(response.data);
    } catch (error) {
      console.error(error);
    }
  };

  const handleChange = (selectedValue) => {
    onChange(selectedValue);
  };

  return (
    <Select
      value={value}
      onChange={handleChange}
      style={{ width: '100%' }}
      placeholder="Select a supplier"
    >
      {data.map((item) => (
        <Option key={item.id} value={item.id}>
          {item.name}
        </Option>
      ))}
    </Select>
  );
};

export default SupplierSelect;

3、在父组件中，可以使用SupplierSelect组件并与Form同步数据

javascript 复制代码

import React, { useState } from 'react';
import { Form, Button } from 'antd';
import SupplierSelect from './SupplierSelect';

const MyForm = () => {
  const [form] = Form.useForm();
  const [selectedSupplier, setSelectedSupplier] = useState(null);

  const onFinish = (values) => {
    console.log('Form values:', values);
  };

  return (
    <Form form={form} onFinish={onFinish}>
      <Form.Item label="Supplier" name="supplier">
        <SupplierSelect value={selectedSupplier} onChange={setSelectedSupplier} />
      </Form.Item>
      
      <Form.Item>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
      </Form.Item>
    </Form>
  );
};

export default MyForm;

这样，可以在父组件中使用SupplierSelect组件，并将其与Form同步数据。通过调用setSelectedSupplier函数来更新父组件中selectedSupplier的值，从而保持数据的同步性。
