config.

i had add these following lines webservice config in order able run webservice in browser

<system.web>     <webservices>         <protocols>             <add name="httpget"/>             <add name="httppost"/>         </protocols>     </webservices> </system.web> 

**web service outcome **

i trying call web service php page using ajax jquery running xampp v3.1

jquery

  $.ajax({         type: "get",         url: "http://192.168.25.11/link web service",             data: "",             datatype: "jsonp",             contenttype: "application/jsonp; charset=utf-8",             success: function(data) {                 console.log(data);             }         }); 

error

following how console looks after calling ajax() function

fyi if click on link in second line link webservice , run in first image

notice

if use same webservice same project - domain - can ajax() call , type='json' , works no errors

question

• what i'm doing wrong ?
• do need make webservice return json object instead of xml if yes how

i think problem is, specifying content type json in ajax call. but, web service returning xml.

so, either can specify content type xml in ajax call , process xml (i not sure whether possible or not), or can configure web service return json.

refer question (how return json 2.0 asmx web service) configure web service return json.
