如何在Gmaps4rails 1.5.6中通过ajax更新谷歌地图圈

Question

In my rails application I am using gmaps4rails gem with 1.5.6 version. I want to update my map circle attributes through ajax

Can any one please suggest me a procedure to do this?

Answer 1

First, get your circle, should be in Gmaps.map.circles

Then:

 circle.serviceObject.setRadius(number)

Answer 2

In the success function of ajax, you can code like this:

 Gmaps.loadMaps()
 // if you are using markers
 markers_json = JSON.parse(markers) 
 Gmaps.map.replaceMarkers(markers_json)
 // if you are using circle
 Gmaps.map.clear_circles() 
 circle_json = JSON.parse(circle)
 Gmaps.map.circles = circle_json
 Gmaps.map.create_circles()

Thanks
