## zh-CN

基本使用，通过 `options` 设置自动完成的数据源。

## en-US

Basic Usage, set data source of autocomplete with `options` property.

```tsx
import { AutoComplete } from 'antd';
import React, { useState } from 'react';

const mockVal = (str: string, repeat = 1) => ({
  value: str.repeat(repeat),
});

const App: React.FC = () => {
  const [value, setValue] = useState('');
  const [options, setOptions] = useState<{ value: string }[]>([]);

  const onSearch = (searchText: string) => {
    setOptions(
      !searchText ? [] : [mockVal(searchText), mockVal(searchText, 2), mockVal(searchText, 3)],
    );
  };

  const onSelect = (data: string) => {
    console.log('onSelect', data);
  };

  const onChange = (data: string) => {
    setValue(data);
  };

  return (
    <>
      <AutoComplete
        options={options}
        style={{ width: 200 }}
        onSelect={onSelect}
        onSearch={onSearch}
        placeholder="input here"
      />
      <br />
      <br />
      <AutoComplete
        value={value}
        options={options}
        style={{ width: 200 }}
        onSelect={onSelect}
        onSearch={onSearch}
        onChange={onChange}
        placeholder="control mode"
      />
    </>
  );
};

export default App;
```
