Answer Source
  // string to keep the result
  var output = "";
  // iterate over all inputs with class 'as_sym' inside the '#sym_form'
  $('#sym_form > input[class=as_sym]').each(function(){
    // only inputs with non-empty values                                                                                                        
    if ($(this).val() != "") {
      // the first value doesn't have a comma in front of it
      // subsequent values do have a comma in front of them
      if (output == "") {
        output += $(this).val();
      } else {
        output += "," + $(this).val();
  // here do whatever you want with the 'output' variable
