Elemento Place Details

PlaceDetailsElement es un elemento HTML que renderiza los detalles de un lugar. Existen dos métodos que se usan para configurar el elemento gmp-place-details:

  • El método configureFromPlace renderiza el elemento Place Details según un ID de lugar o un objeto Place.
  • El método configureFromLocation renderiza el elemento Place Details en función de las coordenadas de latitud y longitud.

En el ejemplo de esta página, se renderiza el elemento Place Details cuando el usuario hace clic en el mapa. Para agregar detalles de lugares a un mapa, agrega un elemento gmp-place-details a la página HTML. Establece su tamaño y posición con los atributos size y slot, respectivamente. En el siguiente ejemplo, está anidado dentro de un elemento gmp-map con size establecido en medium y slot establecido en control-inline-start-block-start. 

<gmp-map center="47.759737, -122.250632" zoom="16" map-id="DEMO_MAP_ID">
  <div class="widget-container" slot="control-inline-start-block-start">
    <gmp-place-details size="x-large"></gmp-place-details>
  </div>
  <gmp-advanced-marker></gmp-advanced-marker>
</gmp-map>
index.html

Se usa un querySelector para seleccionar cada elemento de la página para la interacción:

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

El controlador de eventos en el siguiente fragmento renderiza el elemento Place Details según la ubicación del clic del usuario en el mapa:

// Add an event listener to handle map clicks.
    map.innerMap.addListener('click', async (event) => {
        marker.position = null;
        event.stop();
        if (event.placeId) {
            // Fire when the user clicks a POI.
            await placeDetails.configureFromPlace({ id: event.placeId });
        }
        else {
            // Fire when the user clicks the map (not on a POI).
            await placeDetails.configureFromLocation(event.latLng);
        }
        // Get the offset center.
        let adjustedCenter = offsetLatLngRight(placeDetails.place.location, -0.005);
        // Show the marker at the selected place.
        marker.position = placeDetails.place.location;
        marker.style.display = 'block';
        map.innerMap.panTo(adjustedCenter);
    });
}
index.js
