这里 Maps API - group.getBoundingBox 不是函数

Here Maps API - group.getBoundingBox is not a function

尝试对地图标记进行分组,然后聚焦并缩放该组。

我已遵循文档:Zooming to a Set of Markers

脚本

    public viewGroupMarkers() {
        // CREATE MARKERS
        const toronto = new H.map.Marker({lat:43.7,  lng:-79.4});
        const boston = new H.map.Marker({lat:42.35805, lng:-71.0636});
        const washington = new H.map.Marker({lat:38.8951, lng:-77.0366});
        // CREATE GROUP
        const group = new H.map.Group();
        group.addObjects([toronto, boston, washington]);
        // ADD GROUP TO MAP
        this.map.addObject(group);
        // GET VIEW BOUND GROUP
        this.map.getViewModel().setLookAtData({
          bounds: group.getBoundingBox()
        });
      }

...但是在尝试 group.getBoundingBox 时出现错误:

getBoundingBox 方法在 API 的最新 (3.1) 版本的 Group 对象中引入。

我认为您仍然加载旧版 3.0 API。

您有两个选择:

  1. 迁移到版本 3.1(推荐)。 migration guide 应该可以帮助您切换到 3.1 版。
  2. 将方法更改为 getBounds()
