创建插件

看来 jQuery 你已经用得很爽了，想学习如何自己编写插件。非常好，这篇文档正适合你。用插件和方法来扩展 jQuery 非常强大，把最聪明的功能封装到插件中可以为你及团队节省大量开发时间。

The Revealing Module Pattern in Javascript

Zach Caceres

Javascript does not have the typical 'private' and 'public' specifiers of more traditional object oriented languages like C# or Java. However, you can achieve the same effect through the clever application of Javascript's function-level scoping. The Revealing Module pattern is a design pattern for Javascript applications that elegantly solves this problem.

The central principle of the Revealing Module pattern is that all functionality and variables should be hidden unless deliberately exposed.

Let's imagine we have a music application where a musicPlayer.js file handles much of our user's experience. We need to access some methods, but shouldn't be able to mess with other methods or variables.

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

每个开发者根据一个base branch（在我们的前端项目中大多数情况下为develop）创建一个自己的feature branch
完成feature branch开发以后，确认无误，push到相应的branch上
在github网站上，可以看到

点击Compare & pull request 4. 选择创建时的base branch，后面是自己的branch，并且填写pull request记录, create pull request
