这可能是一个javascript问题,但由于它还处理Rails变量和gmpas4rails gem我还是想问你...

我认为这是

<%= gmaps(
    { 
     "markers"     => { "data" => @json },

     "circles"     => { "data" => '[
                         {"lng": 122.214897, "lat": 37.772323, "radius": 25000, "strokeColor": "#FF0000"}
                         ]',
                      },
    }
        ) %>

我有圈子的部分我想要这个

"circles"     => { "data" => '[
                         {"lng": '@shop.longitude', "lat": '@shop.latitude', "radius": 25000, "strokeColor": "#FF0000"}

因此,对于每个商店,它都会将圆圈居中并绘制区域......

你不应该逃避纬度和经度:

"circles" => { 
  "data" => "[{'lng': #{@shop.longitude}, 'lat': #{@shop.latitude}, 'radius': 25000, 'strokeColor': '#FF0000'}]"
}

替代解决方案:

"circles" => { 
  "data" => [{'lng' => @shop.longitude, 'lat' => @shop.latitude, 'radius' => 25000, 'strokeColor' => '#FF0000'}].to_json
}
