Sharepointplus: Trying to acces values in a SP list, but returning only nulls. (SP 2013) SOLVED

Question

My goal is to read columns from the list TestList and write the element into an other list's new form's textbox TestText. But looks like even if I can acces the TestList the script return only with nulls. For example if the targeted column Szam have 4 elements then it return with 4 null if I add one more element it returns with 5 null, but I can't figure out why not contains the right values. Here is my code:

$(document).ready(function () {

        $SP().list("TestList","http://.../sites/Registry/").get(
        {
            fields: "Szam"
        },
        function getData(data)
            for (var i = 0; i < data.length; i++) {
               console.log(data[i].getAttribute("Szam"));
               // $("#TestText").val(data[i].getAttribute("Szam"));
            }
      });
});

Both SP list is under the same site. I am using SP 2013, jquery.min.js and sharepointplus-4.0.min.js. The column Szam contains 5 element as text {1,2,3,4,5}. I as a result I can see the "null"s in the console log 5 times. In the final version I am planning to add something like where 'Szam = "5"' and search in other columns to get only 1 element as result and insert it to the TestText. I am new to both SP and JS so it can be even trivial mistakes. Thank you very much for your kind help!

Thanks for using my Library :-)

First thing: the parameter is view, not views (see documentation).

Then, are you into the same website where you're doing the above code? If yes, no need to provide the URL. Also try to remove the view and add a where clause:

$SP().list("TestList").get({fields:"ID,Szam", where:"ID > 0"}, function(data)   {
  console.log("len => ",data.length); // to check the number of results
  data.forEach(function(d) {
    console.log(d.getAttribute("ID"),"=>",d.getAttribute("Szam"));
  })
})

Check the console of your browser to see the result.

Also, check the response body from the console to see what the server returned to you. It usually is a good way to see what might be wrong.
