前端项目实战贰佰伍拾伍react-admin+material ui-react-admin-admin中AutocompleteInput之isLoading

import { useGetList, AutocompleteInput } from 'react-admin';
 
const UserCountry = () => {
    const { data, isLoading } = useGetList('countries');
    // data is an array of { id: 123, code: 'FR', name: 'France' }
    return (
        <AutocompleteInput 
            source="country"
            choices={data}
            optionText="name"
            optionValue="code"
            isLoading={isLoading}
        />
    );
}

自动完成时候显示一条加载信息
