1、indexedDB（Model） -- 前端瀏覽器對象型數據庫，一般我們後台用的數據庫都是關係型數據庫。那麼indexeddb有什麼特點呢：
首先，從字義上它是索引型數據庫，從實際使用中可以體現為，它需要為表創建索引才可以根據某個字段來獲取數據，而在關係型數據庫中，這明顯是不需要的。
其次，我不需要行列數據的轉化，我只需要通過類似於數組的處理方式：
複製代碼代碼如下:
objectStore.push(data);
有點像是把一個json對象塞入數據庫，是不是很暴力？
2、bootstrap（View ） -- bootstrap，老實說，我不是很熟悉這個東西，畢竟我是後端java開發出身。以我的理解，這就是一個以響應式佈局為特點的前端框架，至於說比較特別的，應該就是它比較流行吧？ ！老實說，我這邊只用到css，而我也認為，後現代的前端開發，將不會需要bootstrap的js部分，畢竟那還是以jquery為主的方式。
3、angularjs（Controller） -- 必須承認這個東西東西的誕生完全顛覆了我對前端開發的看法，以前和現在我們依然困在前後端無法徹底分離的窘境中，但我認為如果後期，前端人員普遍採用應用式的angularjs腳本來開發（還有一些類似的框架），我們將不再需要讓後端開發工程師套用諸多的前端樣式、結構等等。
這麼說，很多後端人員可能還是不能體會得到，舉個例子：angularjs的使用方式有點像是jsp、freemarker等渲染html的東西，只是一個在客戶端渲染，另一個在後台服務器渲染。我們只要改變數據的結構和屬性，對應渲染出來的頁面就會不同，angularjs就是讓我們更加關注數據的變化，而非DOM的變化，就是說：你將很少會去寫到$("btnSave").click(function() {});這樣需要獲取到html節點的腳本代碼，可以說，這完全脫離了jQuery的範疇。所以這可以算是一個跨時代的改變？
接下來就上例子吧（最終必須運行到服務器上）：
