Javascript 在融合层中可以有多少个不同的标记有限制吗?
我有一个融合表层的实现,我尝试使用带有字母A-Z的预定义标记图标来显示地图上搜索查询的结果(很像最初的谷歌地图) 我实现这一点的方法是首先创建一个层,为所有标记创建一个通用图标Javascript 在融合层中可以有多少个不同的标记有限制吗?,javascript,google-maps-api-3,google-fusion-tables,Javascript,Google Maps Api 3,Google Fusion Tables,我有一个融合表层的实现,我尝试使用带有字母A-Z的预定义标记图标来显示地图上搜索查询的结果(很像最初的谷歌地图) 我实现这一点的方法是首先创建一个层,为所有标记创建一个通用图标 var layer = new google.maps.FusionTablesLayer({ query: { select: 'Geometry', from: 0000000 }, map: map, options: { suppre

同时,我在同一个表中查询25个结果,并根据地图的居中位置(地理位置)按ST_距离排序
返回的JSON对象是唯一ID的数组,我称之为“ID”。然后我使用一些触发器(zoomchanged)用字母图标(insprired by)重新绘制25个最近的图标
现在,除了前5名结果A-D(+1为回退图标)之外,这实际上非常有效。这里出了什么问题?我是否达到了一些限制(MarkeOptions只接受5个值??)或者我是否弄乱了代码
旁注:似乎每层有5个以上的图标,但谷歌制作的,我一个都不懂。对不起,通过地图API只能设置5种样式。该限制在附录中提到。 我怀疑显示所有可能图标的地图不是FT图层。如果通过FT UI完成,您可以拥有更多样式,但这不是动态的,可能不适合您的情况
