Jquery UI - 可排序[Portlet] - 按钮双击

我有jQuery UI - 可排序组件的问题。问题的解释：Jquery UI - 可排序[Portlet] - 按钮双击

点击按钮1 - >导致“警报”
拖动portlet包含Button1以另一列，然后点击按钮1 - >导致“警报”“警报”（行动由点击功能为代表的每个事件两次triggerd）从jQuery UI的网页

简单代码（修改的portlet示例）：

的问题是使y ou将点击函数绑定到portlet本身的html中的button1，所以当jQuery UI克隆一个辅助对象时可能会再次执行它。解决方案很简单，只需将您的Feeds portlet的脚本元素内的代码移动到页面头部的脚本部分（在函数体中，就像由ready处理程序执行的其他代码一样）。
