全面兼容谷歌、火狐、IE浏览器的漂浮广告代码
分类:网页设计 Tags: 兼容浏览器 广告代码 评论:1 浏览:4141 最近更新时间:2014/8/23 13:14:06
优点:
1、兼容性很好
2、可关闭
3、可继续增加漂浮广告,只需要在写一个div(必须重新定义一个不同的ID),多个广告之间,不同步,不重叠
JS代码部分:
function addEvent(obj,evtType,func,cap){ cap=cap||false; if(obj.addEventListener){ obj.addEventListener(evtType,func,cap); return true; }else if(obj.attachEvent){ if(cap){ obj.setCapture(); return true; }else{ return obj.attachEvent("on" + evtType,func); } }else{ return false; } } function getPageScroll(){ var xScroll,yScroll; if (self.pageXOffset) { xScroll = self.pageXOffset; } else if (document.documentElement && document.documentElement.scrollLeft){ xScroll = document.documentElement.scrollLeft; } else if (document.body) { xScroll = document.body.scrollLeft; } if (self.pageYOffset) { yScroll = self.pageYOffset; } else if (document.documentElement && document.documentElement.scrollTop){ yScroll = document.documentElement.scrollTop; } else if (document.body) { yScroll = document.body.scrollTop; } arrayPageScroll = new Array(xScroll,yScroll); return arrayPageScroll; } function GetPageSize(){ var xScroll, yScroll; if (window.innerHeight && window.scrollMaxY) { xScroll = document.body.scrollWidth; yScroll = window.innerHeight + window.scrollMaxY; } else if (document.body.scrollHeight > document.body.offsetHeight){ xScroll = document.body.scrollWidth; yScroll = document.body.scrollHeight; } else { xScroll = document.body.offsetWidth; yScroll = document.body.offsetHeight; } var windowWidth, windowHeight; if (self.innerHeight) { windowWidth = self.innerWidth; windowHeight = self.innerHeight; } else if (document.documentElement && document.documentElement.clientHeight) { windowWidth = document.documentElement.clientWidth; windowHeight = document.documentElement.clientHeight; } else if (document.body) { windowWidth = document.body.clientWidth; windowHeight = document.body.clientHeight; } if(yScroll < windowHeight){ pageHeight = windowHeight; } else { pageHeight = yScroll; } if(xScroll < windowWidth){ pageWidth = windowWidth; } else { pageWidth = xScroll; } arrayPageSize = new Array(pageWidth,pageHeight,windowWidth,windowHeight) return arrayPageSize; } var AdMoveConfig=new Object(); AdMoveConfig.IsInitialized=false; AdMoveConfig.ScrollX=0; AdMoveConfig.ScrollY=0; AdMoveConfig.MoveWidth=0; AdMoveConfig.MoveHeight=0; AdMoveConfig.Resize=function(){ var winsize=GetPageSize(); AdMoveConfig.MoveWidth=winsize[2]; AdMoveConfig.MoveHeight=winsize[3]; AdMoveConfig.Scroll(); } AdMoveConfig.Scroll=function(){ var winscroll=getPageScroll(); AdMoveConfig.ScrollX=winscroll[0]; AdMoveConfig.ScrollY=winscroll[1]; } addEvent(window,"resize",AdMoveConfig.Resize); addEvent(window,"scroll",AdMoveConfig.Scroll); function AdMove(id){ if(!AdMoveConfig.IsInitialized){ AdMoveConfig.Resize(); AdMoveConfig.IsInitialized=true; } var obj=document.getElementById(id); obj.style.position="absolute"; var W=AdMoveConfig.MoveWidth-obj.offsetWidth; var H=AdMoveConfig.MoveHeight-obj.offsetHeight; var x = W*Math.random(),y = H*Math.random(); var rad=(Math.random()+1)*Math.PI/6; var kx=Math.sin(rad),ky=Math.cos(rad); var dirx = (Math.random()<0.5?1:-1), diry = (Math.random()<0.5?1:-1); var step = 1; var interval; this.SetLocation=function(vx,vy){x=vx;y=vy;} this.SetDirection=function(vx,vy){dirx=vx;diry=vy;} obj.CustomMethod=function(){ obj.style.left = (x + AdMoveConfig.ScrollX) + "px"; obj.style.top = (y + AdMoveConfig.ScrollY) + "px"; rad=(Math.random()+1)*Math.PI/6; W=AdMoveConfig.MoveWidth-obj.offsetWidth; H=AdMoveConfig.MoveHeight-obj.offsetHeight; x = x + step*kx*dirx; if (x < 0){dirx = 1;x = 0;kx=Math.sin(rad);ky=Math.cos(rad);} if (x > W){dirx = -1;x = W;kx=Math.sin(rad);ky=Math.cos(rad);} y = y + step*ky*diry; if (y < 0){diry = 1;y = 0;kx=Math.sin(rad);ky=Math.cos(rad);} if (y > H){diry = -1;y = H;kx=Math.sin(rad);ky=Math.cos(rad);} } this.Run=function(){ var delay = 10; interval=setInterval(obj.CustomMethod,delay); obj.onmouseover=function(){clearInterval(interval);} obj.onmouseout=function(){interval=setInterval(obj.CustomMethod, delay);} } } function closead() { var obj = document.getElementById( "floatAdd" ); obj.style.visibility = "hidden"; }
