我正在学习Gmaps4Rails教程，并试图在引导框架中实现它，但遇到了一些问题。地图无法正确加载。。。放大功能不起作用

但这只起到了微乎其微的作用。这似乎是如何设置引导的问题，或者我的require树不正确。有关我的相关代码，请参见下文

我也有同样的问题。你能尝试使用地理定位方法，并将地图设置为以用户位置为中心吗。检查它的工作情况

if(navigator.geolocation)
navigator.geolocation.getCurrentPosition(displayOnMap);

 function displayOnMap(position){
 var marker = handler.addMarker({
 lat: position.coords.latitude,
 lng: position.coords.longitude,
 picture: {
      url: "Keep Any Image",
      width:  36,
      height: 36
    },
    infowindow: "You"
});
handler.map.centerOn(marker);
}

此脚本从表中读取数据并添加标记

将此代码添加到脚本末尾index.html.erb的脚本标记中。请参阅并查看地理位置示例的代码。谢谢，这使我的地图得以显示，但右上角仍然无法正确显示。我的报告也没有出现在地图上。我的项目也面临着同样的问题。“我的地图”在左上角有一个可见的小矩形，但当你调整浏览器的大小时，它会显示出来，你可以试试看。对于填充标记，我有一个适合我的解决方法。我为选项卡式面板添加了一个onclick。我在一个隐藏表中显示数据，然后使用jquery创建标记。
