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;

const Complete: React.FC = () => {
  const [result, setResult] = React.useState<string[]>([]);
  const handleSearch = (value: string) => {
    let res: string[] = [];
    if (!value || value.indexOf('@') >= 0) {
      res = [];
    } else {
      res = ['gmail.com', '163.com', 'qq.com'].map(domain => `${value}@${domain}`);
    }
    setResult(res);
  };
  const children = result.map((email: string) => (
    <Option key={email} value={email}>
      {email}
    </Option>
  ));
  return (
    <AutoComplete style={{ width: 200 }} onSearch={handleSearch} placeholder="input here">
      {children}
    </AutoComplete>
  );
};

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