参考vux移动端的ui组件，做了一个picker，测试在微信，uc主流浏览器能够正常工作。而在华为浏览器根本不能使用。而测试了vux的原有picker组件，发现在华为自带浏览器中，效果依然能够实现。
这时明白，原来vux也并非想的那么简单，兼容性这块做的很不错。或者是因为采用了vue的缘故？
实现代码如下：

滑动这块采用的是touch事件；
过渡效果利用的是css3的animation.css文件；
利用了一个以前没有应用的api：animationend，用来监控animation是否结束，结束后发生回调。
其它利用classlist对类进行增删。
做了一下兼容下，transform和transition的兼容性。
后面需要优化一下。
优化浏览器兼容性滑动。
