//这是一个动态显示图片新闻的脚本 //调用代码样例： //var imgabc; //var imageRepeatMethod = 'imgabc.nextImage()'; //function doabc(){ // debugger; // var imgNews = new Array(); // var imgLinks = new Array(); // imgNews[0] = "Images/Category/200619hyq.gif"; // imgLinks[0] = "abc.asp"; // imgNews[1] = "Images/Category/200619yousheng.gif"; // imgLinks[1] = "def.asp"; // // imgabc = new ImageTransition(imgNews,imgLinks,'imageNewrotator'); //} //HTML代码样例： // // //

// // //最近修改时间:2006.9,zouyong //images为图片新闻的数组，imgLinks为每张图片的链接地址,imgRotator为显示图片的控件ID function ImageTransition(images,imgLinks,imgTexts,imgRotator,imgTextPanel){ this.images = images; this.imgLinks = imgLinks; this.imgTexts = imgTexts; this.imgRotator = document.getElementById(imgRotator); this.imgTextPanel = document.getElementById(imgTextPanel); this.imgIndex = 0; this.preLoadedImages = new Array(); for (i = 0; i < this.images.length; i++){ this.preLoadedImages[i] = new Image(); this.preLoadedImages[i].src = this.images[i]; } this.nextImage(); } //程序入口 ImageTransition.prototype.nextImage = function(){ if(this.imgIndex < this.images.length-1){ this.imgIndex++; } else{ this.imgIndex = 0; } this.setTransition(); this.imgRotator.src = this.images[this.imgIndex]; this.playTransition(); theTimer = setTimeout(imageRepeatMethod, 4000); } //设置变换效果 ImageTransition.prototype.setTransition = function(){ if (document.all){ this.imgRotator.filters.revealTrans.Transition = Math.floor(Math.random()*23); this.imgRotator.filters.revealTrans.apply(); } } //播放效果 ImageTransition.prototype.playTransition = function(){ if (document.all){ this.imgRotator.filters.revealTrans.play(); this.imgTextPanel.innerHTML = imgTexts[this.imgIndex]; } } //跳转到指定的URL ImageTransition.prototype.jump2url = function(){ jumpUrl = this.imgLinks[this.imgIndex]; jumpTarget = '_blank'; if (jumpUrl != ''){ if (jumpTarget != ''){ window.open(jumpUrl,jumpTarget); } else{ location.href = jumpUrl; } } } //显示状态信息 ImageTransition.prototype.displayStatusMsg = function() { status = this.imgLinks[this.imgIndex]; document.returnValue = true; }
