<div id="Carousel" style="position:relative">
<img src="photo/200310171/placeholder.gif" width="371" height="225"> // 修改宽度和高度,注意和上面的配合
</div>
第二步:修改<body***>中的内容，将下面的代码加入原<body***>中
onload="Carousel()"
2、飘动的文字
代码提示：将下面的代码复制到〈BODY〉与〈/BODY〉中
<script language="JavaScript1.2">
//configure message
message="欢迎光临中国IT热线！！"
//animate text in NS6? (0 will turn it off)
ns6switch=1
var ns6=document.getElementById&&!document.all
mes=new Array();
mes[0]=-1;
mes[1]=-4;
mes[2]=-7;mes[3]=-10;
mes[4]=-7;
mes[5]=-4;
mes[6]=-1;
num=0;
num2=0;
txt="";
function jump0(){
if (ns6&&!ns6switch){
jump.innerHTML=message
return
}
if(message.length > 6){
for(i=0; i != message.length;i++){
txt=txt+"<span style='position:relative;' id='n"+i+"'>"+message.charAt(i)+"</span>"};
jump.innerHTML=txt;
txt="";
jump1a()
}
else{
alert("Your message is to short")
}
}
function jump1a(){
nfinal=(document.getElementById)? document.getElementById("n0") : document.all.n0
nfinal.style.left=-num2;
if(num2 != 9){
num2=num2+3;
setTimeout("jump1a()",50)
}
else{
jump1b()
}
}
function jump1b(){
nfinal.style.left=-num2;
if(num2 != 0){num2=num2-3;
setTimeout("jump1b()",50)
}
else{
jump2()
}
}
function jump2(){
txt="";
for(i=0;i != message.length;i++){
if(i+num > -1 && i+num < 7){
txt=txt+"<span style='position:relative;top:"+mes[i+num]+"'>"+message.charAt(i)+"</span>"
}
else{txt=txt+"<span>"+message.charAt(i)+"</span>"}
}
jump.innerHTML=txt;
txt="";
if(num != (-message.length)){
num--;
setTimeout("jump2()",50)}
else{num=0;
setTimeout("jump0()",50)}}
</script>
<h2><div id="jumpx" style="color:green"></div></h2>
<script>
if (document.all||document.getElementById){
jump=(document.getElementById)? document.getElementById("jumpx") : document.all.jumpx
jump0()
}
else
document.write(message)
</script>
2、可拖动的菜单
一：将下面的代码放在〈HEAD〉与〈/HEAD〉之间，修改background后的颜色代码
<style>
body,td,a {font-size:9pt;color:black}
.none{border:black 1px solid;background:D9D9D9;padding-top:2}
.over {border:black 1px solid;background:707888;color:white;padding-top:2}
</style>
二：修改<body***>中的内容，将下面的代码加入原<body***>中
onmousemove="move()"
三：将下面的代码复制到〈BODY〉区
<div style="position:absolute; left: 100; top: 100; 1; height: 1;cursor: hand" ID=plane onmousedown="down=true;divleft=event.clientX-parseInt(plane.style.left);divtop=event.clientY-parseInt(plane.style.top)"onmouseup="down=false">

onmouseout="this.className='none';runTimerline()">菜单项三</div>

//移动层
