前言
小伙伴们好，很久不见了。最近工作进入正常期了，所以慢慢的悠闲的时间久没有了，所以不能每天水一篇了。
最近也在听师傅（http://home.cnblogs.com/u/aaronjs/）的教导开始阅读jquery源码了，怎么说呢，阅读的效果其实不是太好。
一来是时间断断续续的没有接上，今天读完明天又忘了，到第三天再读的话，就很多都忘记了；
二来是jquery其实还是有一定难度，加之篇幅也很长，所以读起来还是有一点吃力（我甚至有时候有种想睡的感觉），过了2星期才陆陆续续把core读完，结果很多都无法理解，再加油吧。
反正今年的目标就是把jquery读懂，时间多，不着急了。
时间比较紧未做兼容处理，请使用手机/或者使用chrome开启touch功能查看，后期补上兼容方案，以及修复BUG
关于工作
最近工作上需要在我们的网页上加入一些动画：
① 页面的切入切出的转场动画
② 模仿一个iphone的日历控件
转场动画做的时候其实碰到了很多坑，而且最后做出的效果也一般，因为既有的框架与dom结构已经出来了好久了，改不得，而且就算改了效果也不能保证好，所以暂时放下
这里说的仿iphone日历控件，不如说模仿一个单选框来的实在，而且我这里说是插件，完全就算标题党了，各位可以忽视，所以今日正题吧。
iphone的感觉
第一步我们要找到iphone的感觉，那么iphone是个什么感觉呢：
大概是这么个感觉，但是我做出来却变成了这种感觉，将就着看吧：
总体思路
PS：现在其实正在写功能代码，所以，现在我们是边写边做的，思路乱了各位请包涵
测试代码
这个代码很烂，各位就不要看了，我都不知道怎么写出来的，后面点整理吧，里面的CSS不想写就直接拿别人的用了

关于iscroll
最开始我们总是喜欢找一些已经存在了的解决方案来试试，这样就比较简单了，但是iscroll有一定问题就是他太大了。
最简单的压缩了都快10k了，所以直接给毙了，这里暂时就用不到他了。
zepto的touch事件
我是一个喜欢偷懒的人，我看着zepto有touch事件，本来想拿来直接用用谁知道。。。
1 // Zepto.js 2 // (c) 2010-2012 Thomas Fuchs 3 // Zepto.js may be freely distributed under the MIT license. 4 5 ;(function($){ 6 var touch = {}, 7 touchTimeout, tapTimeout, swipeTimeout, 8 longTapDelay = 750, longTapTimeout 9 10 function parentIfText(node) { 11 return 'tagName' in node ? node : node.parentNode 12 } 13 14 function swipeDirection(x1, x2, y1, y2) { 15 var xDelta = Math.abs(x1 - x2), yDelta = Math.abs(y1 - y2) 16 return xDelta >= yDelta ?

这个就是zepto的touch事件，可以看到他只是对touchend有所监控，会触发一点点事件，所以和我们没有一毛钱关系
在此我便认命的自己敲下了以下代码：
1 document.addEventListener("touchstart", touchStart, false); 2 document.addEventListener("touchend", touchEnd, false); 3 document.addEventListener("touchmove", touchMove, false);
鼠标拖动
该功能的第一个技术点，便是元素跟着鼠标移动，拖到哪里就是哪里，这个大家都比较熟悉了，就不多说
touchend
当拖动结束时，我们要做很多后续的工作：
① 让选项进入既定的轨道
② 是否具有动画效果
③ 动画效果的步长等
PS：开始觉得有几个点可以说说，结果真的写出来却无话可说了，哎。。。。。。
经过以上版本，我们的粗制滥造版便出现了，就是以上的代码。
封装
于是我们就可以在这个基础上整理代码，封装起来了，请看下一步。
整理封装
首先，我们虽然写的不是插件，但是还是应该让他有插件的样子，来点简单的修饰吧。
经过一阶段的休整，我们的代码成了这个样子了：

其中动画步长可以自己调节，选一个自己认为合适的，下面接着更新。

以上代码基本框架都出来了，也有注释，有兴趣的朋友自己看看，我们现在进行最后一步了，将日历搞上去，老夫来不起了。。。
