2.说说谷歌地图,谷歌地图的热力图我就不说了,https://developers.google.com/maps/documentation/javascript/examples/ 这里面有实例的。 a.谷歌地图支持热力图叠加,但是没有海量点,这一点让我很难过,如果全部画marker的话,数据点太多,加载太卡 b.这就用到了谷歌聚合点,如图 3.代码实例,主要看看引用了哪些个文件...
这个类型没有构造函数,但是据Google Maps API官网称GMarkerOptions可以被JavaScript脚本实例化,而JavaScript脚本中通常采用create方法来实例化对象,例如: GMarkerOptions.create(); 2)属性 实例化完成之后,可以访问GMarkerOptions的10个可选属性。在创建GMarker对象的时候,无须这样创建GMarkerOptions对象,直接指定属性即可。

We can also control the amount of point of interest icons and names visible on the map. Just go toCustomize -> Mapsand turn down downLabels: Turning down labels removes all the text from a map. Step 5. Change our marker style
