Question

我有一个表格，其中有4个字段，分别是服务，金额，税金，操作。
问题是，当我选中任何行中的复选框时，第二行表中也添加了相同的行数据，其中包含服务，金额，税金，操作等表字段。
但是我想删除第二个表中的最后一个字段，如动作。
下面是我的代码

检查此代码段。希望对您有帮助！

$(document).ready(function() {
  $(document).on("change", ".tot_amount", function() {
    var $tr = $(this).closest("tr");
    var $trClass = $(this).closest("tr").attr("class");
    if (this.checked) {
      $("#table2 tbody").append("<tr class='"+ $trClass +"'>" + $tr.html() + "</tr>");
      $("#table2 tbody").find('input').parent().remove();
    } else {
    	
      $('#table2').find(".servicetr").each(function() {
        if($tr.hasClass("subscription")){
        	$("#table2").find(".subscription").remove();
        } else if($tr.hasClass("registration")){
        	$("#table2").find(".registration").remove();
        }
      });
    }
  });
});

这是另一种方式。使用data-id标识要删除的行。

$(document).ready(function(){
  $(document).on("change",".tot_amount",function(){  
    if (this.checked){  
      var $tr = $(this).closest("tr").clone();
      $tr.find("td").last().remove();
      $("#table2 tbody").append($tr);
    } else {
      var $trid = $(this).closest("tr").data('id');  
      $('#table2').find(".servicetr[data-id='" + $trid + "']").remove();
    }
  });
});
