效果图:
js代码:
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;//计时器 this.Index = 0;//显示索引 this._onIndex = -1;//当前索引 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; //初始化显示区域 this._img.style.visibility = "hidden";//第一次变换时不显示红x图 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); }, //设置默认属性 SetOptions: function(options) { this.options = {//默认值 Auto: true,//是否自动切换 Pause: 1000,//停顿时间(微妙) Duration: 1,//变换持续时间(秒) Transition: 23,//变换效果(23为随机) List: [],//数据集合,如果这里不设置可以用Add方法添加 onShow: function(){}//变换时执行 }; Extend(this.options, options || {}); }, Start: function() { clearTimeout(this._timer); //如果没有数据就返回 if(!this.List.length) return; //修正Index if(this.Index < 0 || this.Index >= this.List.length){ this.Index = 0; } //如果当前索引不是显示索引就设置显示 if(this._onIndex != this.Index){ this._onIndex = this.Index; this.Show(this.List[this.Index]); } //如果要自动切换 if(this.Auto){ this._timer = setTimeout(Bind(this, function(){ this.Index++; this.Start(); }), this.Duration * 1000 + this.Pause); } }, //显示 Show: function(list) { if(isIE){ //设置变换参数 with(this._img.filters.revealTrans){ Transition = this.Transition; Duration = this.Duration; apply(); play(); } } this._img.style.visibility = ""; //设置图片属性 this._img.src = list.img; this._img.alt = list.text; //设置链接 !!list["url"] ?
