本文实例讲述了js实现精美的图片跟随鼠标效果实现方法。分享给大家供大家参考。具体实现方法如下：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>精美js鼠标跟随代码</title>
</head>
<body>
<script>
A=document.getElementById
B=document.all;
C=document.layers;
T1=new Array("trail1.gif",38,35,"trail2.gif",30,31,"trail3.gif",28,26,"trail4.gif",22,21,"trail5.gif",16,16,"trail6.gif",10,10)
var offsetx=15
var offsety=10
nos=parseInt(T1.length/3)
rate=50
ie5fix1=0;
ie5fix2=0;
rightedge=B"CUR"+i,i*10,i*10,i*3+1,i*3+2,"","<img src='"+T1[i*3]+"' width="+T1[(i*3+1)]+" height="+T1[(i*3+2)]+"border=0>")
}
function createContainer(N,Xp,Yp,W,H,At,HT,Op,St){
with (document){
write((!A && !B) "<layer id='"+N+"' left="+Xp+" top="+Yp+" width="+W+" height="+H : "<div id='"+N+"'"+"style='position:absolute;left:"+Xp+"; top:"+Yp+"; width:"+W+"; height:"+H+"; ");
if(St){
if (C)
write(" style='");
write(St+";' ")
}
else write((A || B)"'":"");
write((At)">" : ">");
write((HT) "");
if (!Op)
closeContainer(N)
}
}
function closeContainer(){
document.write((A || B)"</div>":"</layer>")
}
function getXpos(N){
if (A)
return parseInt(document.getElementById(N).style.left)
else if (B)
return parseInt(B[N].style.left)
else
return C[N].left
}
function getYpos(N){
if (A)
return parseInt(document.getElementById(N).style.top)
else if (B)
return parseInt(B[N].style.top)
else
return C[N].top
}
function moveContainer(N,DX,DY){
c=(A)"";
if (!B){
rightedge=window.innerWidth-T1[1]-20
bottomedge=window.pageYOffset+window.innerHeight-T1[2]
}
c.left=Math.min(rightedge, DX+offsetx);
c.top=Math.min(bottomedge, DY+offsety);
}
function cycle(){
//if (IE5)
if (document.all&&window.print){
ie5fix1=document.body.scrollLeft;
ie5fix2=document.body.scrollTop;
}
for (i=0;i<(nos-1);i++){
moveContainer("CUR"+i,getXpos("CUR"+(i+1)),getYpos("CUR"+(i+1)))
}
}
function newPos(e){
moveContainer("CUR"+(nos-1),(B)"cycle()",rate)
</script>
</body>
</html>
