以前使用ASP.NET WebForm开发时，喜欢使用Repeater控件嵌套的方式开发前台页面，这样就不用JS拼接HTML或者后台拼接HTML了，写出的HTML页面美观、简捷、易于维护，由于不用JS拼接HTML，所以JS写的也很少。
最近使用ASP.NET MVC开发，前台页面的功能比较复杂，每次刷新整个页面的话体验会很差，所以通过JS控制页面元素，实现局部刷新。刚开始使用的方法是通过JS在前台拼接HTML，结果JS写的很长，要命的事，每增加一个新功能，都要拼接很长的HTML，结果页面的JS越写越多。考虑到后期可能难以维护，所以花了半天的时间，对页面进行了大改，把这一个页面拆分成了四个页面，通过jQuery的load方法实现局部更新，修改之后页面清爽多了。
本来想使用ASP.NET MVC的PartialView实现，结果路由的问题遇到点麻烦。最后发现直接使用View也可以，就用View实现了，效果是一样的，不必太钻牛角尖。
模板页面代码(用了两层Layout嵌套)：
