HTML5 localStorage 本地存储文件

HTML5 的localStorage用的是SQLite数据库存储数据的，默认其中只有一张名为itemTable的表；

表中有两个字段: key和value，用来存储键值对

至于本地存储文件的位置Google了好久才找到，直接引用stackoverflow的片段：

Chrome on mac:

~/Library/Application Support/Google/Chrome/<Profile>/Local Storage/

commonly:

~/Library/Application Support/Google/Chrome/Default/Local Storage/

Internet explorer:

I am a bit unsure, but think this will do the trick

%userprofile%\AppData\LocalLow\Microsoft\Internet Explorer\DOMStorage
