如何在laravel中获取dropdown中的记录？

<form action="/your-route" method="POST">
    @csrf
    <select name="dropdown">
        @foreach($records as $record)
            <option value="{{ $record->id }}">{{ $record->name }}</option>
        @endforeach
    </select>
    <button type="submit">Submit</button>
</form>

Route::post('/your-route', 'YourController@handleDropdown');

public function handleDropdown(Request $request)
{
    $selectedRecordId = $request->input('dropdown');
    $selectedRecord = Record::find($selectedRecordId);

    // 处理选中的记录
    // ...

    return redirect()->back();
}
