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:

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
