在rails中，用于谷歌映射的Javascript没有正确地响应ajax请求。

In rails I have a bunch of 'notices' in the html, each of which has latitude and longitude attributes for a corresponding marker on a google map. I send an ajax request to the notices controller when the google map boundaries change. It returns all notices with coordinates inside the map boundaries, and also an array containing all the information necessary for the map to place the corresponding markers.In rails I have a bunch of 'notices' in the htm
