jQuery实现自定义右键菜单的树状菜单效果

 更新时间：2015年09月02日 11:21:46   作者：企鹅  
这篇文章主要介绍了jQuery实现自定义右键菜单的树状菜单效果,涉及jquery鼠标事件及页面元素操作的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了jQuery实现自定义右键菜单的树状菜单效果。分享给大家供大家参考。具体如下：

这是一款基于jQuery的自定义右键菜单，在树状结构的子节点（下级没有节点）上单击右键才会弹出自定义菜单，而且菜单是自动根据鼠标位置来定位的。当鼠标在菜单以外的任意空白处单击一下后会自动消失。这里想特别说明一点所谓的“菜单以外”，可以有两种解剖方式——1、除了鼠标在菜单区域内的所有位置；2、如下图所示的A、B、C、D四个区域。显然用第一种方法来剖析会更简单直接一点。源码中的!IsInArea就表示此方法。

运行效果截图如下：
