[qlik sense 3.0] I can't receive array of rows from field programmatically. Please Assist.

[Anonymous]

Hello devs!

I'm beginner in qlik and I'm trying work with Qlick Sense 3.0 programmatically

I have a function:

function whenMonthsSelected(fieldName){


    var field = app.field(fieldName);


    var fieldData = field.getData();


    console.log("fieldData");
    console.log(fieldData);


    console.log(fieldData.rows.length);


}

And after executing it, i have in browser console next:

In the result i have array with 0 rows.

Of course field has a rows with values.

And my question is...

What should i do to receive array with 12 rows?

If it possible, please write answer more detail, because looks like i do not understand how it works.

Thanks.

Looks like I should use promise, but i do not understand how.
