带预览图的js切换效果！
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
效果圖：
js代碼：
var isIE = (document.all) ? true : false;var $ = function (id) {return "string" == typeof id ? document.getElementById(id) : id; };var Class = {create: function() {return function() { this.initialize.apply(this, arguments); }} }var Extend = function(destination, source) {for (var property in source) {destination[property] = source[property];} }var Bind = function(object, fun) {return function() {return fun.apply(object, arguments);} }var Each = function(list, fun){for (var i = 0, len = list.length; i < len; i++) { fun(list[i], i); } };//ie only var RevealTrans = Class.create(); RevealTrans.prototype = {initialize: function(container, options) {this._img = document.createElement("img");this._a = document.createElement("a");this._timer = null;//計時器this.Index = 0;//顯示索引this._onIndex = -1;//當前索引this.SetOptions(options);this.Auto = !!this.options.Auto;this.Pause = Math.abs(this.options.Pause);this.Duration = Math.abs(this.options.Duration);this.Transition = parseInt(this.options.Transition);this.List = this.options.List;this.onShow = this.options.onShow;//初始化顯示區域this._img.style.visibility = "hidden";//第一次變換時不顯示紅x圖this._img.style.width = this._img.style.height = "100%"; this._img.style.border = 0;this._img.onmouseover = Bind(this, this.Stop);this._img.onmouseout = Bind(this, this.Start);isIE && (this._img.style.filter = "revealTrans()");this._a.target = "_blank";$(container).appendChild(this._a).appendChild(this._img);},//設置默認屬性SetOptions: function(options) {this.options = {//默認值Auto: true,//是否自動切換Pause: 1000,//停頓時間(微妙)Duration: 1,//變換持續時間(秒)Transition: 23,//變換效果(23為隨機)List: [],//數據集合,如果這里不設置可以用Add方法添加onShow: function(){}//變換時執行};Extend(this.options, options || {});},Start: function() {clearTimeout(this._timer);//如果沒有數據就返回if(!this.List.length) return;//修正Indexif(this.Index < 0 || this.Index >= this.List.length){ this.Index = 0; }//如果當前索引不是顯示索引就設置顯示if(this._onIndex != this.Index){ this._onIndex = this.Index; this.Show(this.List[this.Index]); }//如果要自動切換if(this.Auto){this._timer = setTimeout(Bind(this, function(){ this.Index++; this.Start(); }), this.Duration * 1000 + this.Pause);}},//顯示Show: function(list) {if(isIE){//設置變換參數with(this._img.filters.revealTrans){Transition = this.Transition; Duration = this.Duration; apply(); play();}}this._img.style.visibility = "";//設置圖片屬性this._img.src = list.img; this._img.alt = list.text;//設置鏈接!!list["url"] ?
