I have tried to get this callback function to work. I get no error, but also no data. I have tested my controller in Postman and I get data.

 function GetSelected() {

     $.ajax({
         type: 'GET',
         url: '/api/machine/',
         dataType: "JSON",
         data: "data",
         contentType: "Application/json;charset=utf-8",
         success: backcall  
     })
 };


 function backcall(data) {

     var selectmachine = $("#selectmachine").val();
     var Selectmachine = selectmachine + 1;

     alert('Data er:')

     $.each(function (data) {
         if (data.machinenumber == 3) {
             selected = data.selected;
             alert('Data er:' + selected)
         }
     })
 };

Where are you calling `GetSelected()`? – palaѕн Mar 09 '20 at 15:21
yes. I do. logonmachine(); logoffmachine(); //logonmachine2(); GetSelected(); – Peter Gade Carstensen Mar 09 '20 at 15:25
Is the above statement in the same line? Then `GetSelected()` would be commented and not called thus. – Anurag Srivastava Mar 09 '20 at 15:26
It is not in the same line. – Peter Gade Carstensen Mar 09 '20 at 15:27
I'm not sure this is a dupe of the selected question (although may still be a dupe) – Rory McCrossan Mar 09 '20 at 15:44
@PeterGadeCarstensen what do you see if you add `console.log(data)` to `backcall()`? Also, is there any errors in the console? – Rory McCrossan Mar 09 '20 at 15:44
