PlaceSearchElement to element HTML, który renderuje wyniki wyszukiwania miejsca w postaci listy. Element gmp-place-search można skonfigurować na 2 sposoby:
- Aby wyszukać miejsca określonego typu w danym obszarze, użyj żądania wyszukiwania w pobliżu, aby wyświetlić wyniki wyszukiwania za pomocą
PlaceNearbySearchRequestElement. - Aby wyszukać miejsca w danym obszarze na podstawie zapytania tekstowego, użyj żądania wyszukiwania według tekstu, aby renderować wyniki wyszukiwania za pomocą
PlaceTextSearchRequestElement.
Prośba o wyszukiwanie w pobliżu
Wybierz typ miejsca z menu, aby wyświetlić wyniki wyszukiwania w pobliżu dla tego typu miejsca.
Wyszukiwanie w pobliżu jest skonfigurowane głównie do wyszukiwania według typu miejsca i lokalizacji, a wyniki można sortować według odległości lub popularności za pomocą właściwości rankPreference. Więcej informacji znajdziesz w dokumentacji klasy
PlaceNearbySearchRequestElement.
Ten przykład renderuje element wyszukiwania miejsc w odpowiedzi na wyszukiwanie w pobliżu z wybranym przez użytkownika typem miejsca. Wyświetla też element PlaceDetailsCompactElement dla wybranego miejsca.

Aby dodać element wyszukiwania miejsca do mapy, dodaj do strony HTML element gmp-place-search z zagnieżdżonym elementem gmp-place-nearby-search-request.
<gmp-place-search selectable>
<gmp-place-all-content></gmp-place-all-content>
<gmp-place-nearby-search-request
max-result-count="5"></gmp-place-nearby-search-request>
</gmp-place-search>
Element select umożliwia użytkownikowi wybranie typu miejsca z menu. Dla uproszczenia wymieniono tylko 3 typy miejsc: restauracja, kawiarnia i stacja ładowania pojazdów elektrycznych.
<div class="controls">
<label for="type-select">
Select a place type:
<select id="type-select" class="type-select">
<option value="restaurant">Restaurant</option>
<option value="cafe" selected>Cafe</option>
<option value="electric_vehicle_charging_station">
EV charging station
</option>
</select>
</label>
</div>
Gdy użytkownik wybierze typ miejsca z menu, element gmp-place-nearby-search-request zostanie zaktualizowany, a element wyszukiwania miejsc wyświetli wyniki, jak pokazano w poniższych fragmentach kodu. Markery są dodawane w funkcji pomocniczej addMarkers.
// Add event listeners to the type select and place search elements. typeSelect.addEventListener('change', () => searchPlaces()); placeSearch.addEventListener('gmp-select', (event) => { const { place } = event; markers.get(place.id)?.click(); }); placeSearch.addEventListener('gmp-load', () => { addMarkers(); }); searchPlaces(); }
// The searchPlaces function is called when the user changes the type select or when the page loads. async function searchPlaces() { // Close the info window and clear the markers. infoWindow.close(); for (const marker of markers.values()) { marker.remove(); } markers.clear(); // Set the place search query and add an event listener to the place search element. if (typeSelect.value) { const center = map.center; placeSearchQuery.locationRestriction = { center, radius: 50000, // 50km radius }; placeSearchQuery.locationBias = { center, }; placeSearchQuery.includedTypes = [typeSelect.value]; } }

Żądanie wyszukiwania za pomocą tekstu
Wpisz wyszukiwane słowo w polu wprowadzania i kliknij przycisk Szukaj, aby uzyskać listę miejsc pasujących do tego słowa.
Wyszukiwanie tekstowe jest skonfigurowane głównie do wyszukiwania za pomocą zapytania tekstowego i lokalizacji, a wyniki można zawężać według poziomu cen, oceny i tego, czy miejsce jest obecnie otwarte. Wyniki można też sortować według odległości lub popularności za pomocą właściwości rankPreference. Więcej informacji znajdziesz w dokumentacji klasy
PlaceTextSearchRequestElement.
W tym przykładzie element wyszukiwania miejsca jest renderowany w odpowiedzi na wpisany przez użytkownika tekst. Wyświetla też element PlaceDetailsCompactElement dla wybranego miejsca.

Aby dodać element wyszukiwania miejsc do mapy, dodaj do strony HTML element gmp-place-search z zagnieżdżonym elementem gmp-place-search-text-search-request.
