Asp.net WebAPI - JSONP parser error

[Google User]

Hi,

I am using default WebAPI asp.net project which returns string value when call GET method. When I invoke this method from Phone Gap (Visual Studio Windows Phone Emulator), it always returns method not found error for jsonp. Here is my code

$(document).on('pageinit', '#home', function(){

      $.support.cors = true;

      $.mobile.allowCrossDomainPages = true;

$(document).on('click', '#search', function(){

     var url = 'http://localhost/api/values/5';

      $.ajax({

      method: "get",

      url: url,

      contentType: "application/json; charset=utf-8",

      dataType: "jsonp",

      async:false,

      crossDomain: true,

      cache: false,

      jsonp:'jsonpCallback',

      jsonpCallback:'infoData',

      success: function (result) {

      alert('success');

      },

      error: function(xhr,textStatus,errorThrown) {

      alert(xhr.responseText);

      alert(textStatus);

      alert(errorThrown);

      }

      });

      });

      });

function infoData(jsonObj) {

      alert(JSON.stringify(jsonObj));  // print the raw JSON object

      alert(jsonObj.validJsonDocument); // access the property in your JSON object.

      }

1) Avoid JSONP if at all possible -- it's incredibly insecure. 

2) Make sure `jsonp:'...'` is using the right JSONP callback parameter name and is something your server is going to understand

3) Why not handle the response in `success`?

Hello Kerri,

Thanks for your reply. Here is my comments:

(1) What is the alternate approach to call Web API to replace JSONP call?

(2) I have already attached call, can you please guide me what is wrong in that code, my WEB API simply return string data type.

public class ValuesController : ApiController

    {

        // GET api/values/5

        public string Get(int id)

        {

            return "value";

        }

(3) There is already success and error methods but they are not being invoked by WEB API when I try to invoke from phone emulator. It trigger when I call from web page.

Thanks,

Kumar
