Question

我已加入gem gmaps4rails。我想在地图上显示一些标记（确切地说是3个）和它们的infowindow但是这个宝石带有很多js库并且它减慢了我的网站的负载。我只想在这一页上使用这些库。我想知道如何删除一些不必要的js库。

每个文件都很小，所以列表似乎很大，但代码很少。因此，可能在开发过程中，在第一次渲染它们时会减慢速度，但随后它们会被缓存。

在制作中，它们会在你的应用程序中被压缩。因此存在很难被注意到。

如果您仍然不想在每个页面中使用它们：

在application.js中删除gmaps4rails和下划线的要求
使用以下CDN在页面中包含文件：http://cdnjs.com/libraries/gmaps4rails
