Elemen Place Details

Elemen Detail Tempat berukuran sedang yang ditempatkan di atas Google Maps

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';
});
