【问题描述】：
我正在使用 gmaps4rails 并且当有人单击标记时弹出一个模式时已经有一张地图。在模态中，我想要街景中的地图而不是图片。
到目前为止，这就是我在 index.html.erb 中的内容，我只是对如何执行此操作感到困惑。我知道 gmaps4rails wiki 上有资源，但我什至不知道在我的页面上放置资源的位置。有一些见解的人将不胜感激。

// find the heading by looking from the google car pos to the venue pos
var service = new google.maps.StreetViewService();
service.getPanoramaByLocation( pos, 50, function(result, status) {
if (status == google.maps.StreetViewStatus.OK)

heading = google.maps.geometry.spherical.computeHeading( carPos, pos );
sv.setPov( { heading: heading, pitch: 0, zoom: 1 } );

</script>
这是地图外观的示例，当它打开一个模式时，灰色区域是我要放置另一张地图的位置。
