Laravel 5.6 / Javascript：如何将具有动态输入字段的表单添加到动态生成的表中

Question

我正在开发一个应用程序，该应用程序的一个部分是客户接收新库存的部分。该部分包含购物车。用户搜索商品并将其添加到购物车中，然后可以指定数量并添加收到的商品的序列号。以下是购物车的代码和结构：

 <table class="table table-bordered table-striped" >
              <thead>
              <tr>

                <th>Item</th>
               <th>Stock Qty</th>
               <th>Serials</th>
                <th>Price</th>
                <th>Order Qty</th>
                <th>Total Price</th>

                  <th>Delete</th>
                </tr>
              </thead>
            <tbody>
              @foreach($rawm as $raw )
              <tr>
                <td>{{$raw->mname}}</td>
                <td>{{$raw->pquant.' '.$raw->units}} </td>
                <td><div class="form-group">
                   @if($raw->serial==1)  
     <a href="#" data-toggle="modal" data-target="#modal-def{{$raw->gr}}" class="label  bg-blue" ><i class="fa fa-plus"></i>  <b>Add Serials</b></a>
    <div class="modal fade" id="modal-def{{$raw->gr}}">
          <div class="modal-dialog">

            {
          $rowno=$("#employee_table tr").length;
          $rowno=$rowno+1;
          $("#employee_table tr:last").after("<tr id='row"+$rowno+"'><td><input type='text'  name='serial[]' class='form-control' style='width: 100%;' autocomplete='off'></td><td><input type='button' class='btn btn-danger' value='-' onclick=delete_row('row"+$rowno+"')></td></tr>");

用户可以在购物车中放置多个物品。问题是，当购物车中添加了多个项目时，用于添加序列号的动态表格仅适用于第一个项目。我无法在购物车中的后续项目上添加更多输入字段。如果单击添加，它仍会以第一种形式添加输入字段。
