jquery - 用于使用拖放对列表进行排序或排序的触摸界面

Question

iPhone native 应用程序(例如“股票”应用程序)可让您轻松创建列表，然后拖放列表项以通过放置占位符突出显示来对它们进行排序。

我们有许多应用程序使用 jQuery 来允许基于鼠标的排序或排序功能，与此类似。

但是这些都不能在触摸界面上运行。我有兴趣用支持触摸界面的实现替换这些实现。

有什么想法吗？

我正在寻找这个http://jqueryui.com/demos/sortable/#default ，但支持移动/触摸界面。

[更新]:YUI 不再开发，您应该检查 https://shopify.github.io/draggable/或https://rubaxa.github.io/Sortable/或http://touchpunch.furf.com/

YUI 3 拖放模块已完全准备好透明地与触摸界面配合使用，您无需编写任何特定代码。

我已经在 iPad 和 Android 手机(以及 Windows 上的 IE、Firefox、Chrome)上尝试过。

您可以尝试这里的示例:

...以及该页面中引用的其余示例。

我现在正在一个项目中使用它，如果您提出更具体的问题，我也许可以提供进一步的帮助。
