Using jQuery UI Resizable I'm trying to prevent resizing based on various rules.
The built-in containment feature doesn't seem to work properly with absolutely positioned
elements, and I would need something more flexible than that anyway. Having something

上面的html显示了手风琴。 我需要做的是为整个手风琴内容提供一个滚动条，其工作方式如下： 当第一个div滚动到达结束时，第二个div将打开，在第二个div滚动完成时（如果没有滚动，那么同样的事情也将发生），第3个div将打开。 现在，这需要向下滚动，当用户向上滚动时也应如此。
请让我知道必须应用的解决方案，以实现上述类型的功能。

这是更新的javascript，当你向上滚动它也会起作用，它会关闭当前窗格并打开上一个窗格。这是有效的JSBIN演示http://jsbin.com/viwojelico/2/edit?html,js
