看到效果显示了吧!!!

脚本说明：
第一步：把如下代码加入<body>区域中:
<script LANGUAGE="JavaScript">
<!-- Beginning of JavaScript - 
// Your messages. Add as many as you like
var message=new Array()
message[0]="欢迎光临国内最大的新闻站点---新浪网!"

// the URLs of your messages
var messageurl=new Array()
messageurl[0]="http://www.sina.com.cn/"

// the targets of the links
// accepted values are '_blank' or '_top' or '_parent' or '_self'
// or the name of your target-window (for instance 'main')
var messagetarget=new Array()

// the text of your links. In this sample it's the word 'more'
var linktext="去看看"
// font-size
var fntsize=11

// font-color
var fntcolor="FFFF00"

var scrollerwidth=200

// height of the textbox (pixels)

// width of the border (pixels)
var scrollerborder=2

// width of the textpadding (pixels)
var textpadding=15

// do not edit the variables below
var textwidth=scrollerwidth-(2*textpadding)
var textcontent=""
var bgcontent=""
var i_message=0
var i_stepwave=0
var i_maxstepwave=20
pause=pause*1000
if (fntweight==1) {fntweight="700"}
else {fntweight="100"}

function initiate() {
gettextcontent()
getbgcontent()
if (document.all) {
wavemessage.innerHTML=textcontent

}
}

function enlargewave() {
if (i_stepwave<=i_maxstepwave) {
wavemessage.filters.wave.phase=i_stepwave
wavemessage.filters.wave.strength=i_stepwave
wavemessage.filters.wave.lightstrength=i_stepwave
wavemessage.filters.wave.freq=i_stepwave
i_stepwave++
var timer=setTimeout("enlargewave()",50)
}
else {

}
}

function reducewave() {

gettextcontent()

}

}

function gettextcontent() {
textcontent="<span style='font-size:"+fntsize+"pt;font-family:"+fntfamily+";font-weight:"+fntweight+";width:"+textwidth+"px'>"
textcontent+="<font color="+fntcolor+">"+message[i_message]+"</font> "

}

// - End of JavaScript - -->
</script> 
<div ID="wavemessagebg" style="position:absolute;">
</div>
<div ID="wavemessage" style="position:absolute; filter:wave()">
</div>
<div id="deletethisblock" style="position:absolute;top:5px;left:220px;">
</div>

第二步：把<body>中的内容改为：
<body bgcolor="#fef4d9" onLoad="initiate()">
