„Place Search“-Element

Plattform auswählen: Android iOS JavaScript

Das PlaceSearchElement ist ein HTML-Element, das die Ergebnisse einer Ortssuche in einer Liste rendert. Es gibt zwei Möglichkeiten, das Element gmp-place-search zu konfigurieren:

Anfrage „In der Nähe suchen“

Wählen Sie im Menü einen Ortstyp aus, um Suchergebnisse für Orte in der Nähe dieses Typs zu sehen.

Die Suche in der Nähe ist hauptsächlich so konfiguriert, dass nach Ortstyp und Standort gesucht wird. Die Ergebnisse können mit der Eigenschaft rankPreference nach Entfernung oder Beliebtheit sortiert werden. Weitere Informationen finden Sie in der Referenzdokumentation zur PlaceNearbySearchRequestElement Klasse.

In diesem Beispiel wird das Element „Ortssuche“ als Antwort auf eine Suche in der Nähe mit einem vom Nutzer ausgewählten Ortstyp gerendert. Außerdem wird ein PlaceDetailsCompactElement für den ausgewählten Ort angezeigt.

Wenn Sie das Element „Ortssuche“ der Karte hinzufügen möchten, fügen Sie der HTML-Seite ein gmp-place-search-Element mit einem verschachtelten gmp-place-nearby-search-request-Element hinzu. 

<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>

Mit dem Element select kann der Nutzer einen Ortstyp aus dem Menü auswählen. Aus Gründen der Einfachheit sind nur drei Ortstypen aufgeführt: Restaurant, Café und Ladestation für Elektrofahrzeuge. 

<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>

Wenn der Nutzer einen Ortstyp aus dem Menü auswählt, wird das gmp-place-nearby-search-request Element aktualisiert und das Element „Ortssuche“ zeigt die Ergebnisse an, wie in den folgenden Snippets zu sehen ist. Markierungen werden in der Hilfsfunktion addMarkers hinzugefügt. 

// 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', () => {
        void addMarkers();
    });

    searchPlaces();
}
 
// The searchPlaces function is called when the user changes the type select or when the page loads.
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.includedTypes = [typeSelect.value];
    }
}

Anfrage „Nach Text suchen“

Geben Sie einen Suchbegriff in das Eingabefeld ein und klicken Sie auf die Schaltfläche Suchen , um eine Liste von Orten , die dem Begriff entsprechen, zu erhalten.

Die Textsuche ist hauptsächlich so konfiguriert, dass anhand einer Textabfrage und eines Standorts gesucht wird. Die Ergebnisse können nach Preisklasse, Bewertung und danach gefiltert werden, ob der Ort derzeit geöffnet ist. Die Ergebnisse können auch nach Entfernung oder Beliebtheit mit der rankPreference Eigenschaft sortiert werden. Weitere Informationen finden Sie in der Referenzdokumentation zur Klasse PlaceTextSearchRequestElement.

In diesem Beispiel wird das Element „Ortssuche“ als Antwort auf eine Texteingabe des Nutzers gerendert. Außerdem wird ein PlaceDetailsCompactElement für den ausgewählten Ort angezeigt.

Vollständiges Codebeispiel ansehen

Wenn Sie das Element „Ortssuche“ der Karte hinzufügen möchten, fügen Sie der HTML-Seite ein gmp-place-search-Element mit einem verschachtelten gmp-place-search-text-search-request-Element hinzu. 

<gmp-place-search selectable>
    <gmp-place-all-content></gmp-place-all-content>
    <gmp-place-text-search-request
        max-result-count="5"></gmp-place-nearby-search-request>
</gmp-place-search>

Mit dem Element input kann der Nutzer Suchtext eingeben. 

<div class="controls">
    <input
        type="text"
        id="query-input"
        class="query-input"
        placeholder="Search for a place"
        value="cafe" />
    <button id="search-button" class="search-button">
        Search
    </button>
</div>

Wenn der Nutzer auf die Schaltfläche Suchen klickt, wird die Suchfunktion ausgeführt, das gmp-place-text-search-request Element wird aktualisiert und das Element „Ortssuche“ zeigt die Ergebnisse an, wie in den folgenden Snippets zu sehen ist. Markierungen werden in der addMarkers Hilfsfunktion hinzugefügt. 

// Add event listeners to the query input and place search elements.
    searchButton.addEventListener('click', () => {
        searchPlaces();
    });
    queryInput.addEventListener('keydown', (event) => {
        if (event.key === 'Enter') {
            searchPlaces();
        }
    });

    placeSearch.addEventListener('gmp-select', (event) => {
        const { place } = event;
        markers.get(place.id)?.click();
    });
    placeSearch.addEventListener('gmp-load', () => {
        void addMarkers();
    });

    searchPlaces();
}
 
// The searchPlaces function is called when the user changes the query input or when the page loads.
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 (queryInput.value) {
        const center = map.center;
        if (center) {
            placeSearchQuery.locationBias = center;
        }
        // The textQuery property is required for the search element to load.
        // Any other configured properties will be ignored if textQuery is not set.
        placeSearchQuery.textQuery = queryInput.value;
