I have am trying to use getJSON() in an ASP.NET MVC 5 View:

1. var controllerUrl = "@this.Url.Action(actionName:"EditData", controllerName:"Home")";
   $.getJSON({ url: controllerUrl })
       .done(function () {alert("getJSON succeeded"); })
       .fail(function (jqXHR, textStatus, errorThrown) { debugger; alert("getJSON failed: " + textStatus); });

getJSON errors in this part of the jquery.js (version 2.1.3.).   When these variables contain:
      url = undefined
      s.url = an object containing url: "/Home/EditData"
     ajaxLocation =     "http://localhost:51766/Home/EditData"

the code hits this command:

1. s.url = ( ( url || s.url || ajaxLocation ) + "" ).replace( rhash, "" )
               .replace( rprotocol, ajaxLocParts[ 1 ] + "//" );
