Elemento Place Details

O PlaceDetailsElement é um elemento HTML que renderiza detalhes de um lugar. Há dois métodos usados para configurar o elemento gmp-place-details:

  • O método configureFromPlace renderiza o elemento "Place Details" com base em um ID de lugar ou em um objeto Place.
  • O método configureFromLocation renderiza o elemento "Place Details" com base nas coordenadas de latitude e longitude.

O exemplo desta página renderiza o elemento "Place Details" quando o usuário clica no mapa. Para adicionar Place Details a um mapa, adicione um elemento gmp-place-details à página HTML. Defina o tamanho e a posição usando os atributos size e slot, respectivamente. No exemplo abaixo, ele está aninhado em um elemento gmp-map com size definido como medium e slot definido como control-inline-start-block-start. 

<gmp-map center="-37.813,144.963" zoom="2" map-id="DEMO_MAP_ID">
  <gmp-place-details
    size="medium"
    slot="control-inline-start-block-start"></gmp-place-details>
  <gmp-advanced-marker></gmp-advanced-marker>
</gmp-map>

Um querySelector é usado para selecionar cada elemento da página para interação:

const map = document.querySelector('gmp-map');
const placeDetails = document.querySelector('gmp-place-details');
const marker = document.querySelector('gmp-advanced-marker');

O manipulador de eventos no snippet a seguir renderiza o elemento "Place Details" com base na localização do clique do usuário no mapa:

// Add an event listener to handle map clicks.
map.innerMap.addListener('click', async (event) => {
  marker.position = null;
  event.stop();
  if (event.placeId) {
    // The user clicked a point on the map that has a Place ID (for example a
    // POI).
    await placeDetails.configureFromPlace({id: event.placeId});
  } else {
    // The user clicked an area of the map with no Place ID.
    await placeDetails.configureFromLocation(event.latLng);
  }
  // Show the marker at the selected place.
  marker.position = placeDetails.place.location;
  marker.style.display = 'block';
});
