jQuery动态添加、删除表格行

 jQuery实现动态添加或删除表格行特效，每点击一次添加，会添加一个表格单元格，点击删除会删掉所有行

CSS：

<style type="text/css">
        #tb{
            margin: 3% 0 0 5%
        }
        #tb td{
            text-align: center;
            font-weight: bold;
            background-color: #F2F4FF;
            border: 1px solid #F2F4FF;
        }
 </style>

SCRIPT：

<script type="text/javascript" src="jquery-1.4.4.min.js"></script>
  <script type="text/javascript">
        $(document).ready(function() {
            //隐藏模板tr
            $("#tb tr").eq(2).hide();
            var i = 0;
            $("#BtAdd").click(function() {
　　　　　    //复制一行
                var tr = $("#tb tr").eq(2).clone();
                tr.find("td").get(0).innerHTML = ++i;
                tr.show();
                tr.appendTo("#tb");
            });
            //删除选中行
            $("#BtDel").click(function() {
                $("#tb tr:gt(2)").each(function() {
                    if ($(this).find("#CK").get(0).checked == true) {
                        $(this).remove();
                    }
                });
                i = 0;
                $("#tb tr:gt(2)").each(function() {
                    $(this).find("td").get(0).innerHTML = ++i;
                });
                $("#CKA").attr("checked", false);
            });
            $("#CKA").click(function() {
                $("#tb tr:gt(2)").each(function() {
                    $(this).find("#CK").get(0).checked = $("#CKA").get(0).checked;
                });
            });
        })
 </script>
