内容图文
表格的每一行都有一个删除按钮.当用户单击删除按钮时,将弹出一个模式框,提示用户“您是
确定要删除此记录吗？”.如果用户单击“是”,则将从表中删除该行.
我试着做
$(this).closest('tr').remove();
但这不起作用.

</body>
</html>解决方法:
一种方法是在单击行中的删除按钮时在该行上切换所选的类…然后使用模式按钮删除具有该类的行
$('.deletebtn').click(function(){
// remove selected class from other rows
$('tr.selected').removeClass('selected');
// add selected class to current row
$(this).closest('tr').addClass('selected');
});
$("#confirmdeletebtn").click(function() {
$('tr.selected').remove();
});
