要完成此效果需要两个步骤
第一步：把如下代码加入到<head>区域中
<script>
message="Welcome to Javascript Fairyland!"
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("http://www.softii.com/")
}
}
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>
第二步：把如下代码加入到<body>区域中
