Fusion Table Google Maps Second Javascript下拉菜单无效

标签: javascript api google-maps google-fusion-tables

目前我正在创建一个地图,其中包含一个javascript菜单,允许用户使用Google Fusion表格叠加更改为不同的地图视图。我的第一个下拉菜单就像一个魅力。但是,第二个下拉菜单不适用于另一个。我希望这两个人一起工作。例如,有人可以选择“动物”和“机会”,它会显示包含细胞数据“动物”和“机会”的位置。

这是我的Google地图HTML页面:

这是一个解决方案 - 在Chrome中测试过;) - 请注意两个选择元素上的新按钮,refreshFusion方法和id属性。
