HTML

首先我们放置一个带有多条行数据的表格，每行数据末尾有上移、下移和置顶操作。

<table class="table"> 
   <tbody>
    <tr> 
     <td><a href="https://jy.tp.yuanmeng.life/js/88.html" target="_blank" class="title">jQuery仿淘宝图片放大镜插件imagezoom</a></td> 
     <td>2015-05-01</td> 
     <td><a href="#" class="up">上移</a> <a href="#" class="down">下移</a> <a href="#" class="top">置顶</a></td> 
    </tr> 
    <tr> 
     <td><a href="https://jy.tp.yuanmeng.life/js/87.html" target="_blank" class="title">简单jQuery商品属性选择表单</a></td> 
     <td>2015-02-15</td> 
     <td><a href="#" class="up">上移</a> <a href="#" class="down">下移</a> <a href="#" class="top">置顶</a></td> 
    </tr> 
    <tr> 
     <td><a href="https://jy.tp.yuanmeng.life/js/86.html" target="_blank" class="title">jQuery+iPresenter3D旋转图片超炫效果</a></td>

     <td><a href="#" class="up">上移</a> <a href="#" class="down">下移</a> <a href="#" class="top">置顶</a></td> 
    </tr> 
    <tr> 
     <td><a href="https://jy.tp.yuanmeng.life/js/85.html" target="_blank" class="title">jQuery+css3表单验证</a></td> 
     <td>2014-11-11</td> 
     <td><a href="#" class="up">上移</a> <a href="#" class="down">下移</a> <a href="#" class="top">置顶</a></td> 
    </tr> 
   </tbody>
</table>

jQuery

$(function() {
    //上移
    var $up = $(".up") $up.click(function() {
        var $tr = $(this).parents("tr");
        if ($tr.index() != 0) {
            $tr.fadeOut().fadeIn();
            $tr.prev().before($tr);

        }
    });
    //下移
    var $down = $(".down");
    var len = $down.length;
    $down.click(function() {
        var $tr = $(this).parents("tr");
        if ($tr.index() != len - 1) {
            $tr.fadeOut().fadeIn();
            $tr.next().after($tr);
        }
    });
    //置顶
    var $top = $(".top");
    $top.click(function() {
        var $tr = $(this).parents("tr");
        $tr.fadeOut().fadeIn();
        $(".table").prepend($tr);
        $tr.addClass("ontop");
    });
});
