1、indexedDB（Model）-- 前端浏览器对象型数据库，一般我们后台用的数据库都是关系型数据库。那么indexeddb有什么特点呢：
首先，从字义上它是索引型数据库，从实际使用中可以体现为，它需要为表创建索引才可以根据某个字段来获取数据，而在关系型数据库中，这明显是不需要的。
其次，我不需要行列数据的转化，我只需要通过类似于数组的处理方式：
复制代码代码如下:
objectStore.push(data);
有点像是把一个json对象塞入数据库，是不是很暴力？
2、bootstrap（View） -- bootstrap，老实说，我不是很熟悉这个东西，毕竟我是后端java开发出身。以我的理解，这就是一个以响应式布局为特点的前端框架，至于说比较特别的，应该就是它比较流行吧？！老实说，我这边只用到css，而我也认为，后现代的前端开发，将不会需要bootstrap的js部分，毕竟那还是以jquery为主的方式。
3、angularjs（Controller） -- 必须承认这个东西东西的诞生完全颠覆了我对前端开发的看法，以前和现在我们依然困在前后端无法彻底分离的窘境中，但我认为如果后期，前端人员普遍采用应用式的angularjs脚本来开发（还有一些类似的框架），我们将不再需要让后端开发工程师套用诸多的前端样式、结构等等。
这么说，很多后端人员可能还是不能体会得到，举个例子：angularjs的使用方式有点像是jsp、freemarker等渲染html的东西，只是一个在客户端渲染，另一个在后台服务器渲染。我们只要改变数据的结构和属性，对应渲染出来的页面就会不同，angularjs就是让我们更加关注数据的变化，而非DOM的变化，就是说：你将很少会去写到$("btnSave").click(function() {});这样需要获取到html节点的脚本代码，可以说，这完全脱离了jQuery的范畴。所以这可以算是一个跨时代的改变？
接下来就上例子吧（最终必须运行到服务器上）：
