zh-CN

也可以直接传 AutoComplete.Option 作为 AutoComplete 的 children，而非使用 options。

en-US

You could pass AutoComplete.Option as children of AutoComplete, instead of using options。

import { AutoComplete } from 'antd';

const { Option } = AutoComplete;

class Complete extends React.Component {
  state = {
    result: [],
  };

  handleSearch = value => {
    let result;
    if (!value || value.indexOf('@') >= 0) {
      result = [];
    } else {
      result = ['gmail.com', '163.com', 'qq.com'].map(domain => `${value}@${domain}`);
    }
    this.setState({ result });
  };

  render() {
    const { result } = this.state;
    const children = result.map(email => <Option key={email}>{email}</Option>);
    return (
      <AutoComplete style={{ width: 200 }} onSearch={this.handleSearch} placeholder="input here">
        {children}
      </AutoComplete>
    );
  }
}

ReactDOM.render(<Complete />, mountNode);
