具体代码如下所示：

//link = "http://www.myexceptions.net";

//document.getElementById("lka").href=link;

var x = 50,y = 60

var xin = true, yin = true

var step = 1

var delay = 20

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.οnmοuseοver=function(){clearInterval(itl)}

obj.οnmοuseοut=function(){itl=setInterval("float()", delay)}
