Jquery

$(function(){

        $('#po').click(function(){


                var $row = $(this).parents('tr'); 
                alert($row.find('td:eq(0)').html());
                alert($row.find('td:eq(1)').html());
                alert($row.find('td:eq(2)').html());
                alert($row.find('td:eq(3)').html());
                alert($row.find('td:eq(4)').html());

        });
    });

问题：

当我点击po button时，只有它适用于第一行，它不适用于任何其他行吗？

Answer 1

您有重复的ID， ID应该是唯一的，您可以使用类来代替 -

另外，由于你有嵌套表，你需要使用最接近的表 -

var $row = $(this).closest('tr');
