jQuery UI 实例 – 选择(Selectable)
使用鼠标选择单个元素或一组元素。
如需了解更多有关 selectable 交互的细节,请查看 API 文档 可选择小部件(Selectable Widget)。
默认功能
在某个 DOM 元素上或者一组元素上启用 selectable 功能。通过鼠标拖拽选择条目。按住 Ctrl 键,选择多个不相邻的条目。

显示为网格
让 selectable 条目显示为网格,使用 CSS 使得它们带有相同的尺寸且浮动显示。

序列化
写一个函数,在 stop
事件发生时触发,来收集被选中条目的索引值。呈现这些值作为反馈,或者以数据字符串形式进行传递。
