Yer Arama Öğesi

PlaceSearchElement, bir yer aramasının sonuçlarını listede oluşturmak için kullanılan bir HTML öğesidir. gmp-place-search öğesini yapılandırmanın iki yolu vardır:

Yakın çevrede arama isteği

Menüden bir yer türü seçerek bu yer türüyle ilgili yakındaki arama sonuçlarını görebilirsiniz.

Aşağıdaki örnekte, yakındaki bir arama yanıtı olarak Yer Arama öğesi oluşturulur. Basitlik için yalnızca üç yer türü listelenmiştir: kafe, restoran ve elektrikli araç şarj istasyonu. Bir sonuç seçildiğinde, seçilen yer için bir işaretçi ve PlaceDetailsCompactElement görüntülenir. Haritaya Yer Arama öğesini eklemek için aşağıdaki snippet'te gösterildiği gibi HTML sayfasına gmp-place-search öğesi içeren bir gmp-place-nearby-search-request öğesi ekleyin:

<div class="list-container">
  <div id="map-container"></div>
  <div class="controls">
      <select name="types" class="type-select">
      <option value="">Select a place type</option>
      <option value="cafe">Cafe</option>
      <option value="restaurant">Restaurant</option>
      <option value="electric_vehicle_charging_station">EV charging station</option>
      </select>
  </div>

<div class="list-container">
  <gmp-place-search orientation="vertical" selectable>
      <gmp-place-all-content> </gmp-place-all-content>
      <gmp-place-nearby-search-request
      ></gmp-place-nearby-search-request>
  </gmp-place-search>
</div>

<div id="details-container">
   <gmp-place-details-compact orientation="horizontal">
      <gmp-place-details-place-request></gmp-place-details-place-request>
      <gmp-place-all-content></gmp-place-all-content>
  </gmp-place-details-compact>
</div>

Etkileşim için sayfa öğelerini seçmek üzere çeşitli querySelector çağrıları kullanılır:

  const mapContainer = document.getElementById("map-container");
  const placeSearch = document.querySelector("gmp-place-search");
  const placeSearchQuery = document.querySelector("gmp-place-nearby-search-request");
  const detailsContainer = document.getElementById("details-container");
  const placeDetails = document.querySelector("gmp-place-details-compact");
  const placeRequest = document.querySelector("gmp-place-details-place-request");
  const typeSelect = document.querySelector(".type-select");

Kullanıcı menüden bir yer türü seçtiğinde gmp-place-nearby-search-request öğesi güncellenir ve Yer Arama öğesi sonuçları gösterir (addMarkers yardımcı işlevine işaretçiler eklenir): 

  typeSelect.addEventListener('change', (event) => {
    event.preventDefault();
    searchPlaces();
});

function searchPlaces(){
  const bounds = gMap.getBounds();
  placeDetailsPopup.map = null;

  if (typeSelect.value) {
  placeSearch.style.display = 'block';
  placeSearchQuery.maxResultCount = 10;
  placeSearchQuery.locationRestriction = { center: cent, radius: 1000 };
  placeSearchQuery.includedTypes = [typeSelect.value];

  placeSearch.addEventListener('gmp-load', addMarkers, { once: true });
  }
}

Metin isteğiyle arama

Giriş alanına bir arama terimi girin ve terimle eşleşen yerlerin listesini almak için Arama düğmesini tıklayın.

Bu örnek, kullanıcı metin aramasına yanıt olarak yer arama öğesini oluşturur. Bir sonuç seçildiğinde, seçilen yer için bir işaretçi ve PlaceDetailsCompactElement gösterilir. Haritaya Yer Arama öğesini eklemek için aşağıdaki snippet'te gösterildiği gibi HTML sayfasına gmp-place-search öğesi içeren bir gmp-place-search-text-search-request öğesi ekleyin:

  <div id="map-container"></div>
  <div class="controls">
  <input type="text" class="query-input" />
  <button class="search-button">Search</button>
  </div>

  <div class="list-container">
    <gmp-place-search orientation="vertical" selectable>
        <gmp-place-all-content> </gmp-place-all-content>
        <gmp-place-text-search-request></gmp-place-text-search-request>
    </gmp-place-search>
  </div>

  <div id="details-container">
      <gmp-place-details-compact orientation="horizontal">
          <gmp-place-details-place-request></gmp-place-details-place-request>
          <gmp-place-all-content></gmp-place-all-content>
      </gmp-place-details-compact>
  </div>

Etkileşim için sayfa öğelerini seçmek üzere çeşitli querySelector çağrıları kullanılır:

  const mapContainer = document.getElementById("map-container");
  const placeSearch = document.querySelector("gmp-place-search");
  const placeSearchQuery = document.querySelector("gmp-place-text-search-request");
  const queryInput = document.querySelector(".query-input");
  const searchButton = document.querySelector(".search-button");
  const detailsContainer = document.getElementById("details-container");
  const placeDetails = document.querySelector("gmp-place-details-compact");
  const placeRequest = document.querySelector("gmp-place-details-place-request");

Kullanıcı bir arama sorgusu girdikten sonra arama işlevi çalıştırıldığında gmp-place-text-search-request öğesi güncellenir ve yer arama öğesi sonuçları gösterir (addMarkers yardımcı işlevine işaretçiler eklenir): 

searchButton.addEventListener("click", searchPlaces);
queryInput.addEventListener("keydown", (event) => {
    if (event.key == 'Enter') {
        event.preventDefault();
        searchPlaces();
    }
  });

function searchPlaces(){
  if (queryInput.value) {
      placeSearch.style.display = 'block';
      placeSearchQuery.textQuery = queryInput.value;
      placeSearchQuery.locationBias = gMap.getBounds();
      placeSearch.addEventListener('gmp-load', addMarkers, { once: true });
  }
}
