要完成此效果把如下代码加入到<body>区域中
<p align="center"> </p>
<div align="center"><center>
<table border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="100%"><form name="form2" onSubmit="null">
<p><input type="submit" name="banner" VALUE="Submit"
onClick="alert('You have to put an \'action=[url]\' on the form
tag!!')"> <br>
<script language="JavaScript"><!-- Jon Eyrick - tt1234@263.net
// I do not take full credit for this script, I only made half of this..
var id,pause=0,position=0;
function banner() {
// variables declaration
var i,k,msg="内容";// increase msg
k=(30/msg.length)+1;
for(i=0;i<=k;i++) msg+=" "+msg;
// show it to the window
document.form2.banner.value=msg.substring(position,position-30);
// set new position
if(position++==msg.length) position=0;
// repeat at entered speed
id=setTimeout("banner()",60); }
// end -->
banner();
</script></p>
</form>
</td>
</tr>
</table>
</center></div>
<p> </p>
