仿iphone日历插件(beta)

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。。。

 

// Zepto.js

//     (c) 2010-2012 Thomas Fuchs

;(function($){

  var touch = {},

    touchTimeout, tapTimeout, swipeTimeout,

    longTapDelay = 750, longTapTimeout

  function parentIfText(node) {

    return 'tagName' in node ? node : node.parentNode

  }

  function swipeDirection(x1, x2, y1, y2) {

    var xDelta = Math.abs(x1 - x2), yDelta = Math.abs(y1 - y2)

    return xDelta >= yDelta ? (x1 - x2 > 0 ? 'Left' : 'Right') : (y1 - y2 > 0 ? 'Up' : 'Down')

  }

  function longTap() {

    longTapTimeout = null

    if (touch.last) {

      touch.el.trigger('longTap')

      touch = {}

    }

  }

  function cancelLongTap() {

    if (longTapTimeout) clearTimeout(longTapTimeout)

    longTapTimeout = null

  }

  function cancelAll() {

    if (touchTimeout) clearTimeout(touchTimeout)

    if (tapTimeout) clearTimeout(tapTimeout)

    if (swipeTimeout) clearTimeout(swipeTimeout)

    if (longTapTimeout) clearTimeout(longTapTimeout)

    touchTimeout = tapTimeout = swipeTimeout = longTapTimeout = null

    touch = {}

  }

  $(document).ready(function(){

    var now, delta

    $(document.body)

      .bind('touchstart', function(e){

        now = Date.now()

        delta = now - (touch.last || now)

        touch.el = $(parentIfText(e.touches[0].target))

        touchTimeout && clearTimeout(touchTimeout)

        touch.x1 = e.touches[0].pageX

        touch.y1 = e.touches[0].pageY

        if (delta > 0 && delta <= 250) touch.isDoubleTap = true

        touch.last = now

        longTapTimeout = setTimeout(longTap, longTapDelay)

      })

      .bind('touchmove', function(e){

        cancelLongTap()

        touch.x2 = e.touches[0].pageX

        touch.y2 = e.touches[0].pageY

        if (Math.abs(touch.x1 - touch.x2) > 10)

          e.preventDefault()

      })

      .bind('touchend', function(e){

         cancelLongTap()

        // swipe

        if ((touch.x2 && Math.abs(touch.x1 - touch.x2) > 30) ||

            (touch.y2 && Math.abs(touch.y1 - touch.y2) > 30))

          swipeTimeout = setTimeout(function() {

            touch.el.trigger('swipe')

            touch.el.trigger('swipe' + (swipeDirection(touch.x1, touch.x2, touch.y1, touch.y2)))

            touch = {}

          }, 0)

        // normal tap

        else if ('last' in touch)

          // delay by one tick so we can cancel the 'tap' event if 'scroll' fires

          // ('tap' fires before 'scroll')

          tapTimeout = setTimeout(function() {

            // trigger universal 'tap' with the option to cancelTouch()

            // (cancelTouch cancels processing of single vs double taps for faster 'tap' response)

            var event = $.Event('tap')

            event.cancelTouch = cancelAll

            touch.el.trigger(event)

            // trigger double tap immediately

            if (touch.isDoubleTap) {

              touch.el.trigger('doubleTap')

              touch = {}

            }

            // trigger single tap after 250ms of inactivity

            else {

              touchTimeout = setTimeout(function(){

                touchTimeout = null

                touch.el.trigger('singleTap')

          }, 0)

      })

      .bind('touchcancel', cancelAll)

    $(window).bind('scroll', cancelAll)

  })

  ;['swipe', 'swipeLeft', 'swipeRight', 'swipeUp', 'swipeDown', 'doubleTap', 'tap', 'singleTap', 'longTap'].forEach(function(m){

    $.fn[m] = function(callback){ return this.bind(m, callback) }

  })

})(Zepto)

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：

(function () {
var ScrollRadio = function (opts) {
opts = opts || {};
//容器元素
this.wrapper = opts.wrapper || $(document);
this.body = [
'<div class="cui-roller">',
'<ul class="ul-list" style=" position: absolute; width: 100%; z-index: 2; " >',
'</ul>',
'<div class="cui-mask"></div>',
'<div class="cui-lines"> </div>',
'</div>'
].join('');
this.body = $(this.body);

//真正拖动的元素（现在是ul）
this.dragEl = this.body.find('.ul-list');
//数据源
this.data = opts.data || [];
this._changed = opts.changed || null;
//当前选项索引
this.selectedIndex = 0;
//当前选项值
this.key = '';
//当前选项显示的值
this.value = '';

/*
定位实际需要用到的信息
暂时不考虑水平移动吧
*/
this.itemHeight = 0; //单个item高度
this.dragHeight = 0; //拖动元素高度

this.touchTime = 0; //开始时间
this.moveAble = false; //是否正在移动
this.moveState = 'up'; //移动状态，up right down left

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。
