Data from External URL

[login to view URL] a website that gives free area search on map with given coordinates. I am trying to implement this service in my jquery mobile app. The website is in Turkish, you know you can translate with chrome to english. You can test the service, with "Geographic Query" tab at main page and enter "40,0529" for Latitude and "26,2193" for Longitude at inputs. Note: In chrome developer console, you can view the get response as JSON (What i need). Than i need to draw polygon on google map component.
