jQuery操作table数据上移、下移和置顶

jQuery 操作table中的tr换行的步骤如下:

1、获取当前tr

 var $tr = $(this).parents("tr");

2、移动tr

//上移 
$tr.prev().before($tr);
//下移
 $tr.next().after($tr);
//置顶
 $(".table").prepend($tr);

    <link rel="stylesheet" href="css/table.css">
    <script type="text/javascript" src="js/jquery-1.9.0.min.js"></script>

            <div class="clear"></div>
        </div>
        <div class="commonTab marTop20">
            <table cellpadding="0" cellspacing="0" class="table">
                <thead>

                <th>操作</th>
                </thead>
                <tbody>

                    <td >1</td>
                    <td>第一个</td>
                    <td><a class="Up blueColor">上移</a>&nbsp;&nbsp;&nbsp;&nbsp;<a class="down blueColor">下移</a>&nbsp;&nbsp;&nbsp;&nbsp;<a class="top blueColor">置顶</a></td>
                </tr>
                <tr>

                </tr>
                <tr>
                    <td>3</td>
                    <td>第三个</td>
                    <td><a class="Up blueColor">上移</a>&nbsp;&nbsp;&nbsp;&nbsp;<a class="down blueColor">下移</a>&nbsp;&nbsp;&nbsp;&nbsp;<a class="top blueColor">置顶</a></td>
                </tr>
                </tbody>
            </table>
        </div>
    </div>
</div>
</body>
</html>

jquery操作:

 $(document).ready(function(){
            $(".Up").click(function(){
                var $tr = $(this).parents("tr");
                if ($tr.index() != 0) {//判断是否为第一行
                    $tr.prev().before($tr);
                }
            })
            //下移
            var trLength = $(".down").length;
            $(".down").click(function(){
                var $tr = $(this).parents("tr");
                if ($tr.index() != trLength - 1) {//判断是否为最后一行
                    $tr.next().after($tr);
                }
            })
            //置顶
            $(".top").click(function(){
                var $tr = $(this).parents("tr");
                $tr.fadeOut().fadeIn();
                $(".table").prepend($tr);
            })
        })

附 css样式表

@charset "utf-8";
/* CSS Document */
/*格式化样式*/
*{margin:0;padding:0}
body{font:12px/1.5 Microsoft YaHei,Arial, Helvetica, sans-serif;color:#333;background:#edeff3}
table{width:100%; border-collapse:collapse;border:none;border-spacing:0}
a{color:#202020;text-decoration:none;cursor: pointer}
img{border:none}
input{vertical-align:middle;outline:none;font-family:Microsoft YaHei;border:none}
input[type="submit"]{cursor:pointer}
textarea{outline:none;outline:none;border:solid 1px #e2e2e2;resize:none}
ul,ol,dl{list-style:none;}
b,em,i,u,strong{font-weight:normal;font-style:normal;text-decoration:none;}
h1,h2,h3,h4,h5,h6{font-size:14px;font-weight:normal;}

/*公共样式*/
.fl{float:left;}
.fr{float:right;}
.clear{clear:both}
.bord{border-bottom:solid 2px #f2f2f2}
.blueColor {color:#4893cc;}

/**table样式**/
.commonTab {padding: 0 25px; overflow: auto;padding-bottom: 80px;}
.commonTab table tr th {background: #eaeaea;border-left: solid 1px #f9f9f9;}
.commonTab table tr th {height: 35px; background: #eaeaea;font-weight: 100;font-size: 14px;border-left: solid 1px #f9f9f9;}
.marTop20{margin-top:20px}
.commonTab table tr td {border-left: solid 1px #f9f9f9;}
.commonTab table tr td {padding: 8px 0;font-size: 14px; border: solid 1px #f2f2f2;}
.rightSide{margin-left:10px;padding-top:24px;min-height:1000px;}
.screen {padding: 20px;}
.whiteBg{background:#fff;padding-bottom:70px}

 

重要提示:目标 .table请不要嵌套使用,否则$(“.table").parents("tr") 会找错目标!!!切记切记。尽量将.table单独写出来,不要与其它table嵌套使用。
