How to fill an array in each?

Question

JavaScript

$('.fields .services').each(function() {
   var field = $('select option:selected', this).text() + ';' + $('.sum-input', this).val();
         var fields = array();
   alert(field);
      });

this code runs through all the inputs and displays their values ​​in the format

Internet representation; 36300
promotion; 3400, etc.

How can I fill these lines into the fields array?

Answer 1

fields.push(field)

Answer 2

Maybe we should not reinvent the wheel, but take a ready-made serializeArray() method ?
