结合使用sortable.js和html5自定义数据属性

Question

How does one use html5's custom data attribute to sort items using sortable.js. Or how does one define custom sorting parameter using sortable.js

For example in the code below, I'd like to sort with data-timestamp

<ul id="items">
    <li data-timestamp='1'>item Y</li>
    <li data-timestamp='2'>item B</li>
    <li data-timestamp='3'>item Z</li>
</ul>

Using the store feature documented here: https://github.com/SortableJS/Sortable#store

You can pass Sortable a sorted array of the attributes, and set the dataIdAttr to 'data-timestamp'

Sortable.create(el, {
    dataIdAttr: 'data-timestamp',
    store: {
        get: function () {
            return ['1', '2', '3'];
        }
    }
})
