目的：前端（只采用thymeleaf模板+jquery） 實現國際化
由：前端沒有采用流行的vue.js angular 等框架，純html不可以引用js中定義的常量?
采用jquery賦值（維護2個模板（中，英）界面） 直接out
方案：采用/coderifous/jquery-localize/?壹個本地化插件?
a jQuery plugin that makes it easy to internationalize your web site
步驟：?
1 html
<!DOCTYPE><html?lang="en">

function?getCookie(name){?//取cookies函數
