基本思路是封装一个Slider类， 拥有默认初始配置参数。

Slider.prototype(原型链上)拥有实现滑动的方法，通过监听手势，实现滑动的效果。

比较复杂的滑动效果， 可以使用Swiper.js 来实现。

（推荐教程：javascript教程）

代码如下：

/* PollyFill for iOS 5.* */if (!Function.prototype.bind) {  Function.prototype.bind = function (oThis) {    var args = Array.prototype.slice.call(arguments, 1)    var f2bind = this    var fnop = function () {}    var bound = function () {      return f2bind.apply(this instanceof fnop && oThis        ? this        : oThis,        args.concat(Array.prototype.slice.call(arguments)))    }    fnop.prototype = this.prototype    bound.prototype = new fnop()    return bound  }}// 添加浏览器前缀function prefix(style) {  var vendor = (function() {    var transArr = ['transform', 'webkitTransform', 'MozTransform', 'msTranform', 'OTransform'],      vendors = ['', 'webkit', 'Moz', 'ms', 'O'],      elementStyle = document.createElement('div').style    for (var i = 0; i < vendors.length; i++) {      if (transArr[i] in elementStyle) {        return vendors[i]      }    }    return false  })()  if (vendor === false) return false  if (vendor === '') return style  return vendor + style.charAt(0).toUpperCase() + style.substr(1)}var TRANSFORM = prefix('transform'),  TRANSITION = prefix('transition')var Slider = function(options) {  // 初始化配置参数  this.options = $.extend({    slideWrap: '.pages',  // 容器    slideItem: '.page', // 滑动单元的元素    direction: 'Y', // 滑动的方向    effect: 'slide',  // 滑动的效果    triggleDist: 100,  // 触发滑动的手指移动最小位移    followFinger: true, // 是否跟随手指移动    duration: .4,  // 翻页的延时    currentIdx: 0  // 初始显示的页码  }, options)  var EffectDict = {    'slide' : ['slide', 'slide'],    'scale' : ['slide', 'scale']  }  this.pagesWrap = document.querySelector(this.options.slideWrap)  this.pages = document.querySelectorAll(this.options.slideItem)  this.hook = this.options.slideController  this._total = this.pages.length  this._pageX = 0  this._pageY = 0  this._distance = 0 // 页面之间切换的距离  this._moveDist = 0 // touch 滑动的距离  this._supportTouch = 'ontouchend' in window  this._touching = false  this._enter = this[EffectDict[this.options.effect][0]].bind(this)  this._leave = this[EffectDict[this.options.effect][1]].bind(this)  this._init()  this._bindEvents()}Slider.prototype = {  _init: function() {    var width = this.pagesWrap.clientWidth,      height = this.pagesWrap.clientHeight,      currentIdx = this.options.currentIdx,      pages = this.pages,      total = this._total,      distance = this._distance = (this.options.direction == 'Y' ? height : width)    // 初始化各个 page 的位置    for (var i = 0; i < this._total; i++) {      if (i == currentIdx) {        pages[i].classList.add('current')      } else {        this._enter(pages[i], i < currentIdx ? -distance : distance, 2)      }    }  },  _bindEvents: function() {    var _this = this,      pagesWrap = this.pagesWrap    var events = this._supportTouch ?
