No 'Access-Control-Allow-Origin' header is present on the requested resource ajax jquery phonegap

Question

I am trying to run my phonegap app on ripple emulator and calling method from webservice.asmx using ajax method in jquery, but got cors error:

XMLHttpRequest cannot load https:\rippleapi.herokuapp.com\xhr_proxy?tinyhippos_apikey=ABC&tinyhippos_rurl=http%3A//www.my-domain.com/WebService.asmx/selectData. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http:\localhost:4400' is therefore not allowed access. The response had HTTP status code 503.

1. Have given cors on server side (web.config):

<system.webServer> <defaultDocument> <files> <clear /> <add value="index.aspx" /> <add value="WebService.asmx"/> </files> </defaultDocument> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*"/> <add name="Access-Control-Allow-Headers" value="Content-Type"/> </customHeaders> </httpProtocol> </system.webServer> <system.web> <webServices> <protocols> <add name="HttpGet"/> <add name="HttpPost"/> </protocols> </webServices> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web> <system.serviceModel>

2. My AJAX method :

   $.ajax({
   type:"POST",
   crossDomain : true,
   url: "http://www.my-domain.com/WebService.asmx/selectData",
   data: JSON.stringify(campaignData),
   contentType: "application/json; charset=utf-8",
   dataType: "json",
   success: function(msg)
   {
   var response=msg.d;
   var resultLoop=$.parseJSON(response);
   console.log(response)
   },
   error: function(xhr, ajaxOptions, thrownError)
   {
   $.mobile.loading('hide');
   alert("status :"+xhr.status +" thrownError :"+ thrownError +" ajaxOption : "+ ajaxOptions);
   }
   });

Not able to resolved this, don't know where I have done something wrong or missing something where I have to change in code so that it communicate with server and get data.
