<div id="mapContainer" style="width: 100%; height: 400px;"></div>

// 初始化地图
var platform = new H.service.Platform({
  apikey: 'YOUR_API_KEY'
});
var defaultLayers = platform.createDefaultLayers();
var map = new H.Map(
  document.getElementById('mapContainer'),
  defaultLayers.vector.normal.map,
  {
    zoom: 10, // 初始缩放级别
    center: { lat: 52.5, lng: 13.4 } // 初始中心点坐标
  }
);

// 设置最大和最小缩放比例
var mapEvents = new H.mapevents.MapEvents(map);
var behavior = new H.mapevents.Behavior(mapEvents);
var ui = H.ui.UI.createDefault(map, defaultLayers);
map.getViewModel().setLookAtData({
  bounds: map.getViewModel().getLookAtData().bounds,
  zoom: {
    min: 5, // 最小缩放级别
    max: 15 // 最大缩放级别
  }
});
