### 写一个页面路由转场的管理工具 其实这个根本不复杂,主要是两个技术,一个是管理location.hash,一个是页面的切换/转场动画,然后就是维护页面和hash的路由控制。[SUI Mobile](http://m.sui.taobao.org/)可以说就是这么一个东西。那么有没有代码量较少的可以参考学习一下呢, 这儿就有一个:[WeUI](https://weui.io/) ; 代码在: https://weui.io/example.js 这个小实例就实现了一个简单的单页路由,尽管实现比较简单,也没有做兼容性,不过这个小代码还是很有参考和学习价值的,它展示了单页路由转场的核心思想,而SM加强的部分其实就是,页面是动态加载过来的,并且还有缓存机制等等。不管怎样,这个小实例还是实现了单页应用路由转场的主要效果和功能,让我们窥见了单页路由转场技术的真面目。 ```javascript /** * Created by jf on 2015/9/11. * Modified by bear on 2016/9/7. */ $(function () { var pageManager = { $container: $('#container'), _pageStack: [], _configs: [], _pageAppend: function(){}, _defaultPage: null, _pageIndex: 1, setDefault: function (defaultPage) { this._defaultPage = this._find('name', defaultPage);
