Assign multiple child records simultaneously

try this code. it pulls data from a master table and adds them as child records

function ImportIAB( CampaignID) {

 console.log("inside import" + CampaignID);

$.ajaxSetup({
    async: false,
    data: {
        apptoken: APPTOKEN
    }
});



      var Promise = $.get(DBID_IAB, {
           act: "API_DoQuery",
           qid: "5"                       // execute Query ID# ?
        });

$.when ( Promise ).then( function (xml) {
var data = $(xml);
// console.dirxml( data  );

                var CSV = "";
                var records = data.find("record");

// adding the Parent record ID to the CSV data.

$.each(records,function ( index, record) {
var rowID = $('record_id_', record).text();
                                CSV = CSV + CampaignID + "," + rowID + "\n";
        });

                console.log(CSV);
        //alert(CSV);

               try {

                  var Promise1 = $.get(DBID_CampaignIAB,{
                  act: "API_ImportFromCSV",
             records_csv: CSV,
          skipfirst: 0,
                  clist:  "6.10"
                  } );
               } catch (e) {
                  console.log("Error",e);
               }

               console.log("Import Executed");

               try{
                      $.when (Promise1).then( function (xml1) {
                 
                      
                   var import_count = $("num_recs_added", xml1).text();
                           window.location.hash = "tab_2";
                           window.location.reload(true);
                       });
