Elemento di Place Search avanzato (anteprima)

Questa funzionalità è in Anteprima a pagamento (pre-GA) e viene fatturata al livello Pro. I prodotti e le funzionalità pre-GA potrebbero avere un supporto limitato e le modifiche ai prodotti e alle funzionalità pre-GA potrebbero non essere compatibili con altre versioni pre-GA. Le offerte pre-GA sono coperte dai Termini specifici di servizio di Google Maps Platform. Per ulteriori informazioni, consulta le descrizioni della fase di lancio.

Seleziona il componente giusto per il tuo caso d'uso:

• L'elemento Place Search esegue il rendering di un elenco di luoghi in risposta a una query di ricerca. Viene fatturato nel the livello Essentials.
• Elemento di Place Search avanzato (anteprima) estende l'elemento di Place Search, consentendoti di configurare i pulsanti di azione e applicare le opzioni di ricerca e filtro a recensioni e contenuti multimediali. Viene fatturato nel livello Pro.

Il AdvancedPlaceSearchElement è un elemento HTML che esegue il rendering dei risultati di una ricerca di luoghi in un elenco. Esistono due modi per configurare l'elemento gmp-advanced-place-search:

• Per cercare luoghi di un tipo specifico in una determinata area, utilizza la richiesta di ricerca nelle vicinanze per eseguire il rendering dei risultati di ricerca utilizzando PlaceNearbySearchRequestElement.
• Per cercare luoghi in una determinata area in base a una query di testo, utilizza la richiesta di ricerca per testo per eseguire il rendering dei risultati di ricerca utilizzando PlaceTextSearchRequestElement.

Sia la ricerca nelle vicinanze sia la ricerca per testo offrono le stesse funzionalità avanzate, tra cui la personalizzazione dei pulsanti di azione, il filtraggio di recensioni e contenuti multimediali, la configurazione dell'attribuzione di luoghi, e la gestione della selezione e degli errori dei luoghi.

Richiesta di ricerca nelle vicinanze

Seleziona un tipo di luogo dal menu per visualizzare i risultati di ricerca nelle vicinanze per quel tipo di luogo.

La ricerca nelle vicinanze è configurata principalmente per la ricerca per tipo di luogo e località, e i risultati possono essere classificati in base alla distanza o alla popolarità utilizzando la rankPreference proprietà. Per ulteriori dettagli, consulta la documentazione di riferimento della PlaceNearbySearchRequestElement classe.

Questo esempio esegue il rendering dell'elemento Advanced Place Search in risposta a una Nearby Search con un tipo di luogo selezionato dall'utente. Visualizza anche un AdvancedPlaceDetailsCompactElement per il luogo selezionato.

Per aggiungere l'elemento Place Search avanzato alla mappa, aggiungi un gmp-advanced-place-search elemento con un gmp-place-nearby-search-request elemento nidificato alla pagina HTML.

<gmp-advanced-place-search selectable>
    <!-- Nearby search requests require a location restriction to return results. Often set programmatically. -->
    <gmp-place-nearby-search-request max-result-count="5"></gmp-place-nearby-search-request>
    <template slot="details-item">
        <gmp-place-all-content></gmp-place-all-content>
    </template>
</gmp-advanced-place-search>

L'elemento select consente all'utente di scegliere un tipo di luogo da menu. Per semplicità, sono elencati solo tre tipi di luoghi: ristorante, bar, e stazione di ricarica EV.

<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>

Quando l'utente seleziona un tipo di luogo dal menu, l' gmp-place-nearby-search-request elemento viene aggiornato e l' elemento di ricerca di luoghi avanzata visualizza i risultati.

Richiesta di ricerca per testo

Inserisci un termine di ricerca nel campo di immissione e fai clic sul pulsante Cerca per visualizzare un elenco di luoghi che corrispondono al termine.

La ricerca per testo è configurata principalmente per la ricerca utilizzando una query di testo e una località e i risultati possono essere perfezionati in base al livello di prezzo, alla valutazione e al fatto che siano attualmente aperti. I risultati possono anche essere classificati in base alla distanza o alla popolarità utilizzando la rankPreference proprietà. Per ulteriori dettagli, consulta la documentazione di riferimento della classe PlaceTextSearchRequestElement.

Questo esempio esegue il rendering dell'elemento Place Search avanzato in risposta a un input di testo dell'utente. Visualizza anche un AdvancedPlaceDetailsCompactElement per il luogo selezionato.

Per aggiungere l'elemento Place Search avanzato alla mappa, aggiungi un gmp-advanced-place-search elemento con un gmp-place-text-search-request elemento nidificato alla pagina HTML.

<gmp-advanced-place-search selectable>
    <gmp-place-text-search-request max-result-count="5"></gmp-place-text-search-request>
    <template slot="details-item">
        <gmp-place-all-content></gmp-place-all-content>
    </template>
</gmp-advanced-place-search>

L'elemento input consente all'utente di inserire il testo di ricerca.

<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>

Quando l'utente fa clic sul pulsante Cerca , viene eseguita la funzione di ricerca, l'elemento gmp-place-text-search-request viene aggiornato e l'elemento Advanced Place Search visualizza i risultati.

Funzionalità avanzate

Personalizza i pulsanti di azione

Aggiungi i pulsanti di azione come elementi secondari all'interno dell' <template slot="details-item"> elemento del componente di ricerca di luoghi avanzata. Utilizza <gmp-place-link> per le connessioni di navigazione standard e specifica in modo esplicito l'attributo action. Puoi anche specificare l'attributo slot. Le azioni predefinite valide sono open-website, open-directions, open-map, e call. Se l'attributo slot viene omesso, il valore predefinito è action-main.

<gmp-advanced-place-search selectable>
  <gmp-place-text-search-request text-query="pizza" max-result-count="5"></gmp-place-text-search-request>
  <template slot="details-item">
    <gmp-place-name></gmp-place-name>
    <gmp-place-link action="open-website" target="_blank"></gmp-place-link>
    <gmp-place-link action="open-directions" slot="action-corner"></gmp-place-link>
  </template>
</gmp-advanced-place-search>

Filtra recensioni e contenuti multimediali

Questo esempio di codice mostra solo i contenuti multimediali e le recensioni che menzionano "caffè".

<gmp-advanced-place-search selectable>
  <gmp-place-text-search-request text-query="pizza" max-result-count="5"></gmp-place-text-search-request>
  <template slot="details-item">
    <gmp-place-name></gmp-place-name>
    <gmp-place-media query="coffee"></gmp-place-media>
    <gmp-place-reviews query="coffee" rank-preference="newest"></gmp-place-reviews>
  </template>
</gmp-advanced-place-search>

Configura l'attribuzione di luoghi

Per configurare l'attribuzione visiva, aggiungi un <gmp-place-attribution> elemento per visualizzare le configurazioni di attribuzione dei dati dell'API Maps, come l'origine di una foto o di una recensione. Deve essere aggiunto come elemento pari livello diretto di <template>. Le attribuzioni inserite all'interno dell'elemento <template> verranno ignorate.

<gmp-advanced-place-search selectable>
  <gmp-place-text-search-request text-query="pizza" max-result-count="5"></gmp-place-text-search-request>
  <template slot="details-item">
    <gmp-place-name></gmp-place-name>
  </template>
  <gmp-place-attribution light-scheme-color="black" dark-scheme-color="gray"></gmp-place-attribution>
</gmp-advanced-place-search>

Gestisci la selezione e gli errori dei luoghi

Quando è presente l'attributo selectable, puoi ascoltare l'evento gmp-select per recuperare il luogo selezionato dall'utente. Puoi anche ascoltare l'evento gmp-error per gestire con garbo gli scenari in cui non è possibile recuperare i dati dei luoghi.

const searchElement = document.querySelector('gmp-advanced-place-search');

searchElement.addEventListener('gmp-select', (e) => {
  console.log('User selected place: ', e.place);
});

searchElement.addEventListener('gmp-error', (e) => {
  // e.detail contains the structured error payload
  console.error('Failed to load places: ', e.detail.error);
});
