如何使用javascript将在一个输入字段中收集的数组数据传递到另一个输入字段而不会丢失数组属性

$(function () {
            $('#sendit').click(function () {
                var user_id =$('#user_id2').val();
                var all =$('#Senditem').find("input[name='forall[]']").map(function(){return $(this).val();}).get();
                var session = $('#sessionit').val();
                var dateit=Date.now();
                var thisdata='<span style="color: red">No User Selected';

                var div2 = document.getElementById('resultshere');
                div2.innerHTML = '';


                if (user_id < 1){
                    var div = document.getElementById('resultshere');
                    div.innerHTML = thisdata;
                   }else {

                    var posting =
                        $.get(
                            $(this).data('url'),
                            {
                                senddate: dateit,
                                session: $('#sessionit').val(),
                                user_id: $('#user_id2').val(),
                                inputmade: $('#Senditem').find("input[name='forall[]']").map(function () {
                                    return $(this).val();
                                }).get()

                            });


                    $('#destinationtable tr:first').after('<tr><td>'
                        + user_id + all + session + '</td><td> <input name="inputmade" value="'+ dateit+'pim'+user_id+'pim'+all+'pim'+session+ '">waiting to insert ..</td></tr>'
                    );

at a button click the content in input field are collected in an array and pushed to be saved . then the array content gets append to another table. which will later be accessed and saved again every 5 seconds by another javascript below. The issue is, the javascript below never gets the the correct array format

        (function autoinsert() {

            var input=$("#destinationtable td:last").find("input").val();
            // alert(input);

            var req = $.ajax({
                type:"get",
                url:"{{route('AjaxInsertTuckshopIssueAuto')}}",
                data: {postthis: input},
                error: function() {

                },
                success: function(data) {
                    $('#resultshere').html(data)
                      if (input == data ) {
                          function deleterow(tableID) {
                              var table = document.getElementById(tableID);
                              var rowCount = table.rows.length;

                              table.deleteRow(rowCount -1);

                          }
                          deleterow("destinationtableTable");
                      }

                },global: false
            }); setTimeout(autoinsert,5000);
        })();
