总结一下：
有点：网易新闻，微信 热文 都是 -webkit-overflow-scrolling: touch;实现，css实现，轻巧；
bug： 部分安卓浏览器（uc，自带） 只支持持续滑动，不支持回弹，
iphone垂直滑动 第一次不能完全持续滑动到底部；总体不影响使用；
偶尔低端的手机会卡，适当 GPU hack；
iphone safari浏览器会出现滚动条，::-webkit-scrollbar {display: none;0}无效；
.slider_wrap::-webkit-scrollbar,.slider_wrap::scrollbar{ /*iphone safari 无效*/
display:none !important;0px; height:0; line-height:0; -webkit-appearance: none; background:transparent;overflow:hidden;
}
解决办法
父类 overflow-y:hidden 子类 padding-bottom:11px; /*iphone safari 去掉滚动条*/
其他
如果需要js版本的持续滑动菜单 ，请点击 淘宝 xscroll.js 基于kissy框架，
不懂kissy框架。如需独立的，里面找一下，有原生的js，不依赖库的 传送门 http://xscroll.github.io/ ，感觉功能却是完善，但这个组件的体积还是有点稍微大了；
原生独立的xscroll https://github.com/huxiaoqi567/xscroll/blob/master/build/standalone/xscroll.js
自己封装的移动端 触屏滑动条菜单(完善版) ，功能呵呵，能用，兼容没人淘宝的那么强大，也没那么多测试机器，win10触摸屏的不支持；
