使用JavaScript脚本，我们可以制作出类似于屏幕的打字效果。
请看制作方法：
在<body>中插入JavaScript代码：
<script language="JavaScript1.2">
<!--
//设置滚动的内容
var line=new Array()
line[1]="This is an awsome script"
line[2]="It brings up the text you want..."
line[3]="One letter at a time"
line[4]="You can add and subtract lines as you like."
line[5]="It's very cool and easy to use"
//设置字体大小
var ts_fontsize="16px"
//--Don't edit below this line 下列代码不要编辑
var longestmessage=1
for (i=2;i<line.length;i++){
if (line[i].length>line[longestmessage].length)
longestmessage=i
}
//Auto set scroller width
var tscroller_width=line[longestmessage].length
lines=line.length-1 //--Number of lines
//if IE 4+ or NS6
if (document.all||document.getElementById){
document.write('<form name="Bannerform">')
document.write('<input type="text" name="Banner" size="'+tscroller_width+'"')
document.write(' style="background-color: '+document.bgColor+'; color: '+document.body.text+'; font-family: verdana; font-size: '+ts_fontsize+'; font-weight:bold; border: medium none" onfocus="blur()">')
document.write('</form>')
}
temp=""
nextchar=-1;
nextline=1;
cursor="\\"
function animate(){
if (temp==line[nextline] & temp.length==line[nextline].length & nextline!=lines){
nextline++;
nextchar=-1;
document.Bannerform.Banner.value=temp;
temp="";
setTimeout("nextstep()",1000)}
else if (nextline==lines & temp==line[nextline] & temp.length==line[nextline].length){
nextline=1;
nextchar=-1;
document.Bannerform.Banner.value=temp;
temp="";
setTimeout("nextstep()",1000)}
else{
nextstep()}}
function nextstep(){
if (cursor=="\\"){
cursor="|"}
else if (cursor=="|"){
cursor="/"}
else if (cursor=="/"){
cursor="-"}
else if (cursor=="-"){
cursor="\\"}
nextchar++;
temp+=line[nextline].charAt(nextchar);
document.Bannerform.Banner.value=temp+cursor
setTimeout("animate()",25)}
//if IE 4+ or NS6
if (document.all||document.getElementById)
window.onload=animate
// -->
</script>
