Js浮动广告效果实现

第一种漂浮广告不符合W3C
JavaScript漂浮广告代码，很不错，代码精简，不过一次只有漂一个，复制就能用了。希望站长朋友喜欢。

var delay = 10 
var obj=document.getElementById("codefans_net") 
function float() { 
var L=T=0 
var R= document.body.clientWidth-obj.offsetWidth 
var B = document.body.clientHeight-obj.offsetHeight 
obj.style.left = x + document.body.scrollLeft 
obj.style.top = y + document.body.scrollTop 
x = x + step*(xin?1:-1) 
if (x < L) { xin = true; x = L} 
if (x > R){ xin = false; x = R} 
y = y + step*(yin?1:-1) 
if (y < T) { yin = true; y = T } 
if (y > B) { yin = false; y = B } 
} 
var itl= setInterval("float()", delay) 
obj.onmouseover=function(){clearInterval(itl)} 
obj.onmouseout=function(){itl=setInterval("float()", delay)}

第二种漂浮广告不符合标准
Js漂浮广告代码，比较经典的浮动广告，到现还很实用，如果你是一位站长的话，这种代码是必备的，希望对你有用处。

第五种亲自实践过，可以实现从左上角自动移动到右下角

说明：jquery在1.9开始不支持.live()方法的写法而改用.on()，见http://jquery.com/upgrade-guide/1.9/#live-removed.该插件中关闭图片链接使用了.live().请根据自己情况自行修改.
