javascript - 选中复选框时如何获取不同表中的表行数据？

我有一个表，其中提供了一些字段，例如服务，金额，税，操作，当单击复选框时，我希望所有表行数据都可以显示在另一个表上，而当我选择另一个复选框时，我也希望该行数据应该在表格下方添加。

<table cellspacing="0" rules="all" border="1" id="" style="border-collapse:collapse;">
    <tbody>
        <tr>
            <th scope="col">Service </th>
            <th scope="col">Amount</th>
            <th scope="col">tax</th>
            <th scope="col">Action</th>
        </tr>
        <tr>
            <td>
                <span>Subscription Charges</span>
            </td>
            <td>
                <span>500.00</span>
            </td>
            <td>
                <span >90.00</span>
            </td>
            <td >
                <input type="checkbox" data-toggle="checkbox" class="tot_amount" value="590.00"  />
            </td>
        </tr>
        <tr>
            <td>
                <span>registration fees</span>
            </td>
            <td>
                <span>200.00</span>
            </td>
            <td >
                <span >80.00</span>
            </td>
            <td >
                <input type="checkbox" data-toggle="checkbox" class="tot_amount" value="590.00"  />
            </td>
        </tr>
    </tbody>
</table>

<table cellspacing="0" rules="all" border="1" id="" style="border-collapse:collapse;">
    <tbody>
        <tr>
            <th scope="col">Service </th>
            <th scope="col">Amount</th>
            <th scope="col">tax</th>
            <th scope="col">Action</th>
        </tr>
    </tbody>
</table>
<input type="text" name="tot_amount">

最佳答案

$(document).ready(function(){
  $(document).on("change",".tot_amount",function(){
  if (this.checked){
     var servicetext = $(this).closest("tr").find('td').eq(0).find('span').text();
     var totalamt = $('#tot_amount').val();
     if(totalamt != ''){
     $('#tot_amount').val(totalamt + ", " + servicetext);
     }
     else{
     $('#tot_amount').val(servicetext);
     }

      var $tr = $(this).closest("tr");
      $("#table2 tbody").append("<tr class='servicetr'>" + $tr.html() + "</tr>");
  }
  else{
   var $tr = $(this).closest("tr");
   $('#table2').find(".servicetr").each(function(){
     if($tr.html() == $(this).html())
     $(this).remove();
   });

  }
  });
});
