Ajax call returns 200 OK but not calling the web method

Question

I have ajax call as below

$.ajax({
  type: "POST",
  url: "MainPortal/VirtualRoomService.asmx/SaveJunit",
  data: JSON.stringify({
    xjunit: junit,
    data: editor.getData().trim()
  }),
  contentType: "application/json; charset=utf-8",
  async: false,
  dataType: "json",
  success: function(result) {
    if (result.d.split('|')[0] != "-1") {
      $("#<%=lblMessage.ClientID%>").text("Junit saved successfully");
    } else {
      $("#<%=lblMessage.ClientID%>").text(result.d.split('|')[1]);
    }
  },
  error: function(result) {
    if (result.status == 200 && result.statusText == 'OK') {} else {
      alert("FAILED : " + result.status + ' ' + result.statusText);
    }
  }

});

Below is SaveJunit code defined in .asmx web service

[WebMethod(EnableSession = true)]

The ajax call always returns 200 OK but the function is never invoked Below the request data captured from client debugger (chrome)

 {"xjunit":"<?xml version=\"1.0\" encoding=\"utf-8\"?><junit><byline>Mohan</byline><id></id><capid>102</capid><status></status><slug> 17</slug><tags>tags</tags><publication>21</publication><type><id>17</id><name>Text</name></type><label>21</label><deck>deck1</deck><intro>intro</intro><info><infodate></infodate><infotime></infotime><infoloc>loc</infoloc><infotext>info</infotext></info><createdby>7</createdby></junit>","data":"<p>content</p>"}

UPDATE

I have changed

error: function(result) {

to

error: function (jqXHR, textStatus, errorThrown) {

to know about error. textStatus is showing as parsererror and in the errorThrown is showing unexpected end of input

Answer 1

Actually the URL

MainPortal/VirtualRoomService.asmx 

is not pointing to the right location. That is the main issue. Pointing URL to the right location has fixed the issue not sure why response is 200 OK for a bad URL? Hope this answer would would help some one with similar issue.

Answer 2

change this line:

data: JSON.stringify({xjunit: junit, data: editor.getData().trim()}),

to:

data: {xjunit: junit, data: editor.getData().trim()},
