空间属性置顶：
| 属性 | 说明 |
| change | 事件，当控件改变时触发 |
| nestable | 方法，获取顺序JSON数据，形式如下：

今天，有个刚毕业的同事要做一个“排序出港”的功能，看了他用的控件，炫酷程度惊呆了我，而且实现方式非常简单。还是应验了那句老话，你知道多少并不重要，重要的是如何利用你所知道的。
先来看效果：
这么炫酷的一个出港顺序管理，出港顺序直接通过拖拉船名控制。做了Web开发两年，已经习惯了当用户点击的时候做什么操作。实际上，大部分操作都是和数据库打交道。即使玩游戏也是如此，实际上通过拖动来控制顺序是非常炫酷的。
下面用Nestable来尝试实现下：

以上代码实现的东西是，当用户拖拉切换顺序的时候，将顺序的JSON输出到顶部。
显示效果如下：
当然，在切换的时候，如果不是显示在顶部，而是发个AJAX去给数据库Update个顺序，那这种操作，就是刚买电脑的小学生都会灵活运用了。
