自动递增正确格式的序列号

Question

我正在使用CSS添加自动递增序列号，这里我面临的问题是它可以正常工作，但是行并未创建，即未构建其设计。谁能告诉我我在做什么错，我也想显示1..2..3但它在打印我11..22..33吗？我是这些技术的新手。因此，任何帮助将不胜感激

Answer 1

检查以下代码，可以正常工作。

$(document).add(function()
{
 $("#newobj").click(function(){
      var addcontrol="<tr>"
      addcontrol+="<td style='text-align: center;border:1px solid #e3ebf3;'></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="<td><input type='text' ></td>"
           addcontrol+="</tr>"
   $("table tbody").append(addcontrol);
                   });
  //alert("Cannot add more than 8 objectives");
   $(document).on('click', '.remove', function() {
        $(this).parents('tr').remove();

});
});

body
{
    counter-reset: Count-Value;     
}
table
{
    border-collapse: separate;
}
tr td:first-child:before
{
  counter-increment: Count-Value;   
  content: "" counter(Count-Value);
}
