JQuery function wont push nor add value to property

Question

I got this piece of code. Problem is that PUSH wont add anything to the array WORDS or if I try assign value to property. Data in collection that it iterates trough isn't null I tested it and calling other functions from that place in code work for example alert etc.

Thanks for your help.

Here is my piece of code

        var uri = 'GetTickerData';
        var words = [];
        var string;
        $.getJSON(uri)
                .done(function (data) {
                    $.each(data, function (key, item) {
                        words.push('Some text');   //dont work
                        string = 'Another text';   // also dont work
           });
        });

Can you put it on `jsfiddle.net` with the URI so we can test it out — Ali Gajani, May 22 '15 at 11:12

well i dont have problem with data that it returns , if i use for example $('
@Mitre `getJSON` is asynchronous call. So you can access your filled in `words` array only inside `done` callback. — antyrat, May 22 '15 at 11:16
@Mitre How do you know it doesnot work? Where are you checking whats inside `words` and `string`? — Zee, May 22 '15 at 11:22
Well i got piece of code that displays what is inside of WORDS. I also got console log with that from collection and its ok. But i think Antyrat is right and i just cant manipulate with that array in there. — Mitre, May 22 '15 at 11:27

I've not tested this, you'll have to let me know if this works for you

function getReturnedData(callback) {

   var uri = 'GetTickerData';
   var string;

   $.getJSON(uri, function (data) {
        var words = [];
        $.each(data, function (i) {                
              words.push(data[i]);
        });                            
        callback(words);
  });
}

getReturnedData(function(returnValue) {
  console.log(returnValue);
});

I tried it and it didnt work. I can see the Data from that List in Console no problem but that PUSH dont work. Problem is it dont work even with this simple text like words.push('Some text'); also you cant assign value there like var data_string = 'Some other data'; that also dont work there – Mitre May 22 '15 at 11:20
@Mitre are you sure your response contain correct Array? Can you show us response? – antyrat May 22 '15 at 11:21
@Mitre Could you show me some further information, so that I can provided you with a better answer? – YaBCK May 22 '15 at 11:23
Console response is 4x Object that goes like this ObjectCurrentSpeed: 0Date_end: nullDate_start: nullExt_id: nullMaxSpeed: 0Server: "pdcesb001"Severity: "Average"Source: nullStatus: "0"Title: "QPID sft.int.sft.queue depth (delayed)" so its got correct data. – Mitre May 22 '15 at 11:23
@Mitre can we can talk of a stackoverflow chat? and i've also just updated my answer to give you an idea of a callback function – YaBCK May 22 '15 at 11:33
OK that stuff withcallback function solved my problem thank you alot its working now – Mitre May 22 '15 at 11:41
