如何使用javascript根据动态表每一行中的输入值添加天数

Question

我的问题是，我必须根据文本框中给定的输入为动态表的所有行添加天数。 我已经为 2 行添加了天数，但 3,4... 行显示了 2 行的值。 现在我想在第三行添加天数，然后继续…………

       <script type="text/javascript">
    $(function(){

        $("body").on("focusout",function(){

            var trLength=$('body #appendRows tr').length;
            for (var i = 1; i <trLength; i++) {
                $('#appendRows tr:nth-child(2)').remove();
            }


            var val  = $(".ND").val();
             var m  =  $("#follow_Date").val();



                    var j = $("#Amount").val();
                    var k = document.getElementById('txtDate').value;
                    var date = new Date(k);
                    var newdate = new Date(date);
                    newdate.setDate(newdate.getDate() +
                        parseInt(m));

                    var dd = newdate.getDate();
                    var mm = newdate.getMonth() + 1;
                var y = newdate.getFullYear();
                 var someFormattedDate = mm+ '/' + dd + '/' + y;

            var i=1;
            for(i==1;i<val;i++){
                var html = $("#appendRows tr:first-child").clone();
                html.find("input").val("");
                html.find('input[name^="Sno"]').val(i+1);
              html.find('input[name^="Date"]').val(someFormattedDate + parseInt(m));
                 html.find('input[name^="Amount"]').val(j);
                 console.log(date, i, someFormattedDate)
                $('#appendRows').append(html);
            }
        });
    })
</script>

这是一个用于创建表格的javascript代码......................

这是我的动态表格，它将根据文本字段中的输入值创建...

<table class='table table-hover table-bordered table-striped table-xxs' id="cartGrid">
                            <thead>
                                <tr>

                                    <th>Sno</th>
                                    <th >Date</th>
                                    <th >Amount</th>
                                    <th >Bank Name</th>

                                    <th >Payable1</th>
                                </tr>
                                </thead>
                                <tbody id="appendRows">
                                <tr>

                                </tr>
                            </tbody>
                        </table>

这是表格代码........

这是由于启动和模式文本框代码............

基于 cmets，当您在 Mode 输入中输入数字时，使用 Mode 输入上的 keyup 事件添加行...并且只需在第一次出现的日期上添加 0 天

function add() {
  var val = $(".Mode").val();
  var currentdate = document.getElementById('txtDate').value;
  currentdate = getDueDate(currentdate, 0);
  
  $("#appendRows tr").not('.master-row').remove(); // remove previous rows (reset the table)

  for (var i = 0; i < val; i++) {
    
    var someFormattedDate = formatDate(currentdate);
    var html = $("#appendRows tr:first-child").clone();
    html.find("input").val("");
    html.find('input[name^="Sno"]').val(i + 1);
    html.find('input[name^="Date"]').val(someFormattedDate);
    html.removeClass('master-row');
    $('#appendRows').append(html);
    currentdate = getDueDate(currentdate, val);
  }
}

function formatDate(date) {
  var dd = date.getDate();
  var mm = date.getMonth() + 1;
  var y = date.getFullYear();
  return mm + '/' + dd + '/' + y;
}

function getDueDate(from, days) {
  var fromDate = new Date(from);
  var dueDate = new Date(from);
  dueDate.setDate(fromDate.getDate() + days * 1);

  return dueDate;
}
add();
$('.Mode').on('keyup', function() {
  add();
});

.master-row {
  display: none;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
the data
<div>
  <input type="text" class="Mode" value="3">
  <input type="text" id="txtDate" value="12/29/2018">
</div>

<div style="height:20px">

</div>
the table
<table id="appendRows">
  <tr class="master-row">
    <td><input type="text" name="Sno"></td>
    <td><input type="text" name="Date"></td>
  </tr>
</table>

要隐藏“主行”，我会这样做，最好将代码分解为单独的函数
