Elemen Place Search

PlaceSearchElement adalah elemen HTML yang merender hasil Place Search dalam daftar. Ada dua cara untuk mengonfigurasi elemen gmp-place-search:

Permintaan penelusuran di sekitar

Pilih jenis tempat dari menu untuk melihat hasil penelusuran di sekitar untuk jenis tempat tersebut.

Nearby Search terutama dikonfigurasi untuk menelusuri berdasarkan jenis dan lokasi tempat, dan hasilnya dapat diberi peringkat berdasarkan jarak atau popularitas menggunakan properti rankPreference. Lihat dokumentasi referensi class PlaceNearbySearchRequestElement untuk mengetahui detail selengkapnya.

Contoh ini merender elemen Place Search sebagai respons terhadap penelusuran di sekitar dengan jenis tempat yang dipilih pengguna. Elemen ini juga menampilkan PlaceDetailsCompactElement untuk tempat yang dipilih.

Lihat contoh kode lengkap

Untuk menambahkan elemen Place Search ke peta, tambahkan elemen gmp-place-search dengan elemen gmp-place-nearby-search-request bertingkat ke halaman HTML. 

<gmp-place-search selectable>
    <gmp-place-all-content></gmp-place-all-content>
    <gmp-place-nearby-search-request
        max-result-count="5"></gmp-place-nearby-search-request>
</gmp-place-search>

Elemen select memungkinkan pengguna memilih jenis tempat dari menu. Agar lebih mudah, hanya tiga jenis tempat yang dicantumkan: restoran, kafe, dan Stasiun Pengisian Kendaraan Listrik Umum. 

<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>

Saat pengguna memilih jenis tempat dari menu, elemen gmp-place-nearby-search-request akan diperbarui, dan elemen Place Search akan menampilkan hasilnya, seperti yang ditunjukkan dalam cuplikan berikut. Penanda ditambahkan dalam fungsi bantuan addMarkers. 

// Add event listeners to the type select and place search elements.
    typeSelect.addEventListener('change', () => {
        searchPlaces();
    });

    placeSearch.addEventListener('gmp-select', (event) => {
        const { place } = event;
        markers.get(place.id)?.click();
    });
    placeSearch.addEventListener('gmp-load', () => {
        void addMarkers();
    });

    searchPlaces();
}
 
// The searchPlaces function is called when the user changes the type select or when the page loads.
function searchPlaces() {
    // Close the info window and clear the markers.
    infoWindow.close();
    for (const marker of markers.values()) {
        marker.remove();
    }
    markers.clear();

    // Set the place search query and add an event listener to the place search element.
    if (typeSelect.value) {
        const center = map.center;
        placeSearchQuery.locationRestriction = {
            center,
            radius: 50000, // 50km radius
        };
        placeSearchQuery.includedTypes = [typeSelect.value];
    }
}

Permintaan Search by Text

Masukkan istilah penelusuran di kolom input, lalu klik tombol Search untuk mendapatkan daftar tempat yang cocok dengan istilah tersebut.

Penelusuran teks terutama dikonfigurasi untuk menelusuri menggunakan kueri teks dan lokasi, dan hasilnya dapat disaring berdasarkan tingkat harga, rating, dan apakah tempat tersebut saat ini buka. Hasil juga dapat diberi peringkat berdasarkan jarak atau popularitas menggunakan properti rankPreference. Lihat dokumentasi referensi class PlaceTextSearchRequestElement untuk mengetahui detail selengkapnya.

Contoh ini merender elemen Place Search sebagai respons terhadap input teks pengguna. Elemen ini juga menampilkan PlaceDetailsCompactElement untuk tempat yang dipilih.

Lihat contoh kode lengkap

Untuk menambahkan elemen Place Search ke peta, tambahkan elemen gmp-place-search dengan elemen gmp-place-text-search-request bertingkat ke halaman HTML. 

<gmp-place-search selectable>
    <gmp-place-all-content></gmp-place-all-content>
    <gmp-place-text-search-request
        max-result-count="5"></gmp-place-text-search-request>
</gmp-place-search>

Elemen input memungkinkan pengguna memasukkan teks penelusuran. 

<div class="controls">
    <input
        type="text"
        id="query-input"
        class="query-input"

        value="cafe" />
    <button id="search-button" class="search-button">

    </button>
</div>

Saat pengguna mengklik tombol Search, fungsi penelusuran akan dijalankan, elemen gmp-place-text-search-request akan diperbarui, dan elemen Place Search akan menampilkan hasil seperti yang ditunjukkan dalam cuplikan berikut. Penanda ditambahkan dalam fungsi bantuan addMarkers. 

// Add event listeners to the query input and place search elements.

Mengonfigurasi konten

Cuplikan di halaman ini menggunakan gmp-place-all-content untuk menampilkan semua konten yang tersedia untuk setiap tempat dalam hasil. Untuk menampilkan set standar konten, gunakan gmp-place-standard-content.

Untuk memilih konten tertentu, tambahkan elemen <template slot="details-item"> ke elemen gmp-place-search, dan tempatkan elemen konten yang akan ditampilkan untuk setiap tempat di dalam template. Hanya elemen konten yang Anda sertakan yang akan ditampilkan, jadi sertakan gmp-place-name untuk menampilkan nama setiap tempat. Untuk mengonfigurasi atribusi, tambahkan elemen gmp-place-attribution sebagai turunan langsung dari gmp-place-search, di luar template. 

<gmp-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></gmp-place-media>
    <gmp-place-rating></gmp-place-rating>
    <gmp-place-address></gmp-place-address>
  </template>
  <gmp-place-attribution light-scheme-color="black" dark-scheme-color="white"></gmp-place-attribution>
