JS广告代码漂浮效果分析.doc

JS广告代码漂浮效果分析共有三个文件1.htm 主文件、liangbian.js 在两边漂浮的代码 、piaofu.js在全屏幕漂浮的代码把他们的分别保存成三个文件，放在一个目录下，双击1.htm就可以看到效果了。/from /bbs大家可以根据需要更换图片和链接。1.htmliangbian.js/左边var left_img=;/上边是两个左边的图片效果，不够可以继续加，代码就是“”/右边var right_img=;/var right_img=;var delta=0.05var collection;function floaters() this.items = ; this.addItem = function(id,x,y,content) document.write(+content+); var newItem = ; newItem.object = document.getElementById(id); newItem.x = x; newItem.y = y; this.itemsthis.items.length = newItem; this.play = function() collection = this.items setInterval(play(),10); function play() for(var i=0;i0?1:-1)*Math.ceil(Math.abs(dx); followObj.style.left=followObj.offsetLeft+dx; if(followObj.offsetTop!=(document.body.scrollTop+followObj_y) var dy=(document.body.scrollTop+followObj_y-followObj.offsetTop)*delta; dy=(dy0?1:-1)*Math.ceil(Math.abs(dy); followObj.style.top=followObj.offsetTop+dy; followObj.style.display = ; var theFloaters = new floaters();theFloaters.addItem(followDiv1,document.body.clientWidth-100,230,+right_img+);theFloaters.addItem(followDiv2,20,230,+left_img+);theFloaters.play();piaofu.js/可设置漂浮图片是否为FLASH以及显示大小var brOK=false;var mie=false;var vmin=2;var vmax=5;var vr=1;var timer1;var ads;var isflash=0; /是否为FLASH文件的漂浮 1=是 0=否var pic=1.gif; /图片的地址var alt=请点我吧!; /鼠标放在图片上时显示的提示文字var url=/; /图片链接的地址var flashurl=1.swf; /FLASH文件的路径var Wimg=80; /图像的宽度var Himg=80; /图像的高度function movechip(chipname)if(brOK) eval(chip=+chipname); if(!mie) pageX=window.pageXOffset;pageW=window.innerWidth;pageY=window.pageYOffset;pageH=window.innerHeight; else pageX=window.document.body.scrollLeft;pageW=window.document.body.offsetWidth-8;pageY=window.document.body.scrollTop;pageH=window.document.body.offsetHeight; chip.xx=chip.xx+chip.vx; chip.yy=chip.yy+chip.vy; chip.vx+=vr*(Math.random()-0.5); chip.vy+=vr*(Math.random()-0.5); if(chip.vx(vmax+vmin) chip.vx=(vmax+vmin)*2-chip.vx; if(chip.vx(vmax+vmin) chip.vy=(vmax+vmin)*2-chip.vy; if(chip.vy(-vmax-vmin) chip.vy=(-vmax-vmin)*2-chip.vy; if(chip.xx=pageX+pageW-chip.w) chip.xx=pageX+pageW-chip.w;chip.vx=-vmin-vmax*Math.random(); if(chip.xx=680) chip.xx=chip.xx-20;chip.vx=-vmin-vmax*Math.random(); if(chip.yy=pageY+pageH-chip.h) chip.yy=pageY+pageH-chip.h;chip.vy=-vmin-vmax*Math.random(); if(!mie) eval(document.+d+.top =+chip.yy);eval(document.+d+.left=+chip.xx); else eval(document.all.+d+.style.pixelLeft=+chip.xx);eval(document.all.+d+.style.pixelTop =+chip.yy); chip.timer1=setTimeout(movechip(+d+),80);function stopme(chipname)if(brOK) eval(chip=+chipname); if(chip.timer1!=null) clearTimeout(chip.timer1) function ads()if(navigator.appName.indexOf(Internet Explorer)!=-1) if(parseInt(navigator.appVersion.substring(0,1)=4) brOK=navigator.javaEnabled();mie=true;if(navigator.appName.indexOf(Netscape)!=-1) if(parseInt(navigator.appVersion.substring(0,1)=4) brOK=navigator.javaEnabled();d=ads;ads.vx=vmin+vmax*Math.random();ads.vy=vmin+vmax*Math.random();ads.w=1;ads.h=
