        }
    });

can anyone help me in invoking a web service from phonegap app using jQuery .ajax

Answer 1

it will not work until you implement JSONP for your Webservice. JSONP lets remote calles happen, because cross-site XHR calls are not permitted by default.

A nice implementation of JSONP for ASP.Net Webservices:

Answer 2

url: "Service1.asmx/GetCountries"

在应用程序中可以访问此服务URL吗？
