触摸界面，用于使用拖放功能排序或排序列表

Question

iPhone原生应用程序，如股票应用程序，可让您轻松创建列表，然后拖放列表项目并使用拖放占位符突出显示项目对其进行排序。

我们有很多应用程序使用jQuery来允许基于鼠标的排序或排序功能，类似于此。

这些都不能在触摸界面上工作。我有兴趣用支持触摸界面的实现替换这些实现。

任何想法？

我在找这个http://jqueryui.com/demos/sortable/#default，但支持移动/触摸界面。

[更新]：YUI是不再发展，则应该检查https://shopify.github.io/draggable/或https://rubaxa.github.io/Sortable/或http://touchpunch.furf.com/

YUI 3拖放模块充分准备用透明触摸界面的工作，你不必编写任何特定的代码。

我试过在Ipad和Android手机上（也是IE，Firefox，Chrome在Windows上）。

从这里你可以尝试的例子：

...以及在该页面引用的例子休息。

我现在正在项目中使用它，如果您提出更具体的问题，我可能会给予进一步的帮助。

的JavaScript

YUI().use('dd-constrain', 'dd-proxy', 'dd-drop', function (Y) { 
    //Listen for all drop:over events 
    Y.DD.DDM.on('drop:over', function (e) {

      if (!goingUp) { 
       drop = drop.get('nextSibling'); 
      } 
      //Add the node to this list 
      e.drop.get('node').get('parentNode').insertBefore(drag, drop); 
      //Resize this nodes shim, so we can drop on it later. 
      e.drop.sizeShim(); 
     } 
    }); 
    //Listen for all drag:drag events 
    Y.DD.DDM.on('drag:drag', function (e) {

      goingUp = true; 
     } else { 
      //We are going down. 
      goingUp = false;

      if (!drop.contains(drag)) { 
       drop.appendChild(drag); 
      }

    }); 

    //Static Vars 
    var goingUp = false, 
     lastY = 0; 

    //Get the list of li's in the lists and make them draggable
