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，我面临的问题是它工作正常，但行没有创建，即它的设计没有构建。谁能告诉我我做错了什么我也想显示 1..2..3 但它打印我 11..22..33？我是这些技术的新手。

Answer 1

请检查下面的代码是否正常工作。

你的打印结果 11..22..33 因为你已经在标记 td 字段中提到了静态数字并且你通过 CSS 增加了数字所以在这种情况下你需要删除标记中的静态数字以获得准确的结果。
对于设计构建，您只需在自定义 jquery 文件的第一个 td 标记中添加内联 CSS。

$(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);
}
