Elemen Place Details

PlaceDetailsElement adalah elemen HTML yang merender detail untuk suatu tempat. Ada dua metode yang digunakan untuk mengonfigurasi elemen gmp-place-details:

Contoh di halaman ini merender elemen Place Details saat pengguna mengklik peta. Untuk menambahkan Place Details ke peta, tambahkan elemen gmp-place-details ke halaman HTML. Tetapkan ukuran dan posisinya menggunakan atribut size dan slot. Dalam contoh berikut, elemen ini disusun bertingkat dalam elemen gmp-map dengan size disetel ke medium dan slot disetel ke 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>

querySelector digunakan untuk memilih setiap elemen halaman untuk interaksi:

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

Pengendali peristiwa dalam cuplikan berikut merender elemen Place Details berdasarkan lokasi klik peta pengguna:

// 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';
});
