Javascript On Rails

我滴最新开源项目 Javascript On Rails
项目地址:http://code.google.com/p/javascript-on-rails/

不像Jquery 或是 Dojo 针对于DOM 进行封装，
Javascript On Rails 是对javascript 语言进行再次封装，类似于ruby，让javascript更加敏捷和面向对象。
并且结合Jquery 和 图表Flot，组合为强大的客户前端Lib,code for fun

var future = Date.today().add(6).days();

Date.compare(today, future);                    // -1
Date.compare(today, new Date().clearTime());    // 0
Date.compare(today, past)                       // 1

for(var i=0;i<1000;i++) { q.enqueue("aaaaa" + i)}
for(var i=0;i<1000;i++) { print(q.dequeue())}
q.getOldestElement()

#Array 数组操作

var s = "你好 {0}";
s.format("柳争");

正准入学习JavaScript中~~不过对于使用rails来说，还是ruby吧

这个库是类似于 ruby on rails javascript 库，不是ruby的rails底层，是纯javascript的底层实现。 ：）
