使用HTML5的contentmenu事件实现自定义右键菜单的功能

contextmenu事件：用以表示何时应该显示上下文菜单，以便开发人员取消默认的上下文菜单而提供自定义的菜单

效果如下所示

html5左侧弹出菜单怎样实现

这个可以通过绝对定位，配合left设置 或者translate去实现

left的方法：

比如让class为menu的元素宽为300px，高100%的，设置left为-300px；在这期间可以加一个过渡transition:left 0.3s ...；

然后让class为menu active的元素设置 left设置为0就可以了 ，在这期间可以加一个过渡transition:left 0.3s ...；

然后可以通过Jquery的toggleClass('active');来实现切换

translate

比如让class为menu的元素宽为300px，高100%的，设置left为-300px；在这期间可以加一个过渡transition:left 0.3s ...；

然后让class为menu active的元素设置 transform:translate3d(-300px,0,0) ，在这期间可以加一个过渡transition:left 0.3s ...；

然后可以通过Jquery的toggleClass('active');来实现切换

这个过程中 需要注意 body需要overflow：hidden; (不然会有滚动条，可设置overflow-x即可)

left 和 translate 最好用translate ，translate3d可以开启GPU硬件加速，性能会更好，体验会更流畅

我github有类似小组件样式

html5 浮动侧滑菜单栏怎样实现

一共有4种侧滑动画特效。这款CSS3菜单的特点是鼠标划过时即可以各种动画方式展开和隐藏菜单项，该动画方式由CSS3中的transition-delay属性来完成
