<!--完成此效果分成3步
第一步:把下列代码加到<head>区域中-->
<style type="text/css">
.spanstyle {
COLOR: #ffd8ff; FONT-FAMILY: 宋体; FONT-SIZE: 10pt; POSITION: absolute; TOP: -50px; VISIBILITY: visible
}
</style>
<script>
var x,y
var step=18
var flag=0
// Your snappy message. Important: the space at the end of the sentence!!!
var message="★网页教学网欢迎你的光临!"
message=message.split("")
var xpos=new Array()
for (i=0;i<=message.length-1;i++) {
xpos[i]=-50
}
var ypos=new Array()
for (i=0;i<=message.length-1;i++) {
ypos[i]=-200
}
function handlerMM(e){
x = (document.layers) ? e.pageX : document.body.scrollLeft+event.clientX
y = (document.layers) ? e.pageY : document.body.scrollTop+event.clientY
flag=1
}
function makesnake() {
if (flag==1 && document.all) {
for (i=message.length-1; i>=1; i--) {
xpos[i]=xpos[i-1]+step
ypos[i]=ypos[i-1]
}
xpos[0]=x+step
ypos[0]=y
for (i=0; i<message.length-1; i++) {
var thisspan = eval("span"+(i)+".style")
thisspan.posLeft=xpos[i]
thisspan.posTop=ypos[i]
}
}
else if (flag==1 && document.layers) {
for (i=message.length-1; i>=1; i--) {
xpos[i]=xpos[i-1]+step
ypos[i]=ypos[i-1]
}
xpos[0]=x+step
ypos[0]=y
for (i=0; i<message.length-1; i++) {
var thisspan = eval("document.span"+i)
thisspan.left=xpos[i]
thisspan.top=ypos[i]
}
}
var timer=setTimeout("makesnake()",30)
}
</script>
<!--第二步:把如下代码加入<body>区域中-->
<script>
<!-- Beginning of JavaScript -
for (i=0;i<=message.length-1;i++) {
document.write("<span id='span"+i+"' class='spanstyle'>")
document.write(message[i])
document.write("</span>")
}
if (document.layers){
document.captureEvents(Event.MOUSEMOVE);
}
document.onmousemove = handlerMM;
// - End of JavaScript - -->
</script>
<!--第三步:把<body>改为-->
<body bgcolor="#fef4d9" onload="makesnake()">
