Zepto.js 是移动端轻量级的JavaScript框架，实现JQuery的大部分API，针对手机上web开发，轻量级的是相对性的减少用户访问流量

可以到 github上下载zepto的源码也是进行模块划分的

Zepto 思维导向图：

常用返回对象情况：

1、return zepto.Z()，返回一个空的zepto对象：

2、return $(context).find(selector)

3、return $(document).ready(selector)

4、if (zepto.isZ(selector)) return selector

5、return $(context).find(selector)

6、return zepto.Z(dom, selector)

常用方法:

1、$(selector,context?) 传入一个选择器返回一个zepto对象

2、$(function(){}) 传入一个函数，dom ready时执行

3、$(html，attrs?) 传入一个html字符串，构建元素，返回一个或zepto对象

4、$(dom obj)传入dom对象返回zepto对象
