Backbone.js 1.2.1 发布，此版本更新内容如下：
Collection#add now avoids trying to parse a model instance when passing parse: true. Bug fix in Collection#remove. Model#fetch no longer parses the response when passing patch: false. Bug fix for iframe-based History when used with JSDOM. Bug fix where Collection#invoke was not taking additional arguments. When using on
with an event map, you can now pass the context as the second argument.
This was previously an undocumented behavior from 1.1.2 removed
in 1.2.0.

Backbone.js 是一种重量级javascript MVC
应用框架,通过Models进行key-value绑定及custom事件处理,通过Collections提供一套丰富的API用于枚举功能,通过
Views来进行事件处理及与现有的Application通过RESTful JSON接口进行交互.
比较适合于现在的类Twitter web2.0网站的开发! |
