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，我在这里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工作正常。

1. 您的打印结果 11..22..33 因为您已经在标记 td 字段中提到了静态数字，并且您通过 CSS 增加了数字所以在这种情况下，您需要从标记中删除静态数字以获得准确的结果.

2. 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);
}
