在 HERE 地圖上我們可以建立標記,標記的最主要目的是凸顯使用者有興趣的位置點。
以下範例建立互動式地圖,中心點設為台灣,並且建立台北、台中兩個標記。

JavaScript
function addMarkersToMap(map) {
var taipeiMarker = new H.map.Marker({lat:25.03746, lng: 121.564558});
map.addObject(taipeiMarker);
var TaichungMarker = new H.map.Marker({lat:24.138504, lng: 120.678434});
map.addObject(TaichungMarker);
}
//Step 1: 初始化 platform 與建立通訊
var platform = new H.service.Platform({
apikey: window.apikey
});
var defaultLayers = platform.createDefaultLayers();
//Step 2: 初始化地圖,設定中心點在台灣
var map = new H.Map(document.getElementById('map'),
defaultLayers.vector.normal.map,{
center: {lat:25, lng:120},
zoom: 6,
pixelRatio: window.devicePixelRatio || 1
});
window.addEventListener('resize', () => map.getViewPort().resize());
//Step 3: 建立 map events
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));
// 建立預設 UI 元件
var ui = H.ui.UI.createDefault(map, defaultLayers);
window.onload = function () {
addMarkersToMap(map);
}
