Place Search 要素

プラットフォームを選択: Android iOS JavaScript

ユースケースに適したコンポーネントを選択します。

• Place Search Element は、検索クエリに応じて場所のリストを表示します。Essentials ティア で課金されます。
• Advanced Place Search Element（プレビュー版） は、Place Search Element を拡張したもので、アクション ボタンを構成したり、 レビューやメディアに検索オプションやフィルタ オプションを適用したりできます。Pro ティア で 課金されます。

PlaceSearchElement は、場所検索の結果をリストで表示する HTML 要素です。 gmp-place-search要素を設定する方法は 2 つあります:

• 特定の地域の特定のタイプの場所を検索するには、 search nearby リクエストを使用して、検索 結果を PlaceNearbySearchRequestElementを使用して表示します。
• テキストクエリに基づいて特定の地域の場所を検索するには、 search by text request を使用して 検索結果を PlaceTextSearchRequestElement を使用して表示します。

search nearby リクエスト

メニューから場所のタイプを選択すると、その場所のタイプの付近の検索結果が表示されます。

付近の検索は、主に場所のタイプと 場所で検索するように構成されており、結果は距離または人気度でランク付けできます。 rankPreference プロパティを使用します。詳細については、 PlaceNearbySearchRequestElement クラスのリファレンス ドキュメントをご覧ください。

この例では、ユーザーが選択した場所のタイプで付近の検索を行った結果として、Place Search Element を表示します。 また、選択した場所の PlaceDetailsCompactElement も表示します。

Place Search Element を地図に追加するには、ネストされた gmp-place-nearby-search-request 要素を含む gmp-place-search 要素を HTML ページに追加します。

<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>

select 要素を使用すると、ユーザーは メニューから場所のタイプを選択できます。ここでは、レストラン、カフェ、 EV 充電ステーションの 3 つの場所のタイプのみをリスト表示しています。

<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>

ユーザーがメニューから場所のタイプを選択すると、 gmp-place-nearby-search-request 要素が更新され、次のスニペットに示すように、Place Search Element に結果が表示されます。 マーカーは addMarkers ヘルパー関数で追加されます。

// 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();
}
index.js

// 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];
    }

search by text リクエスト

入力フィールドに検索キーワードを入力し、[検索] ボタンをクリックすると、 そのキーワードに一致する場所のリストが表示されます。

テキスト検索は、主にテキストクエリと 場所を使用して検索するように構成されており、料金レベル、評価、現在営業中かどうかで 結果を絞り込むことができます。また、距離または人気度で結果をランク付けすることもできます 。rankPreference プロパティを使用します。詳細については、 PlaceTextSearchRequestElement クラスのリファレンス ドキュメントをご覧ください。
