一个漂亮的导航窗
要完成此效果需要两个步骤
第一步：把如下代码加入到<body>区域中
<script>
<!-- Beginning of JavaScript -
// Edit your messages You can add as many messages a you like
var message = new Array()
message[0]="欢迎光临国内最大的新闻站点---新浪网!"
message[1]="欢迎光临国内最大的综合性站点---网易!"
message[2]="欢迎光临国内最大的搜索引擎---搜狐!"
// The links of your messages Be sure that you configure as many links
as messages
// If don't want to link your messages write '#' instead of an URL (see
last sample)
var messageurl = new Array()
messageurl[0]="http://www.sina.com.cn/"
messageurl[1]="http://www.163.com/"
messageurl[2]="http://www.sohu.com/"
var messagetarget=new Array()
messagetarget[0]="_blank"
messagetarget[1]="_blank"
messagetarget[2]="_blank"
// The width of your textbox (pixels).
// Be sure that 'textwidth' is slightly bigger than the 'width'
configured inside the stylesheet
var textwidth=260
// The height of your textbox (pixels)
// Be sure that 'textheight' is slightly bigger than the 'height'
configured inside the stylesheet
var textheight=75
// Final horizontal position of the textbox: distance to the left
margin of the window (pixels)
// IMPORTANT:
// if you want to center the textbox in the middle of the
browser-window then write -1.
// If you want to place the textbox on an absolute position
// then write the number (for instance 223)
var x_finalpos=-1
// Final vertical position of the textbox: distance to the top margin
of the window
var y_finalpos=20
// Total number of textslices
var textslices=10

var pause=40
// Do not edit the variables below this line

thisspan.posLeft=marginleft
}
moveslices_IE()
}
function moveslices_IE() {
if (x_rightspans==0 || x_leftspans==0) {
if (x_rightspans==0) {
for (I=0;I<=textslices-1;I+=2) {

}
}
}
var timer=setTimeout("moveslices_IE()",pause)
}
else {
clearTimeout(timer)
x_rightspans=0
x_leftspans=0
I_message++
if (I_message > message.length-1) {
I_message=0
}
var timer=setTimeout("changemessage()",pausetext)
}
}
// - End of JavaScript - -->
</script>
<style>

if (document.all) {

marginright=document.body.clientWidth+50
document.write("<span class='textbox' id='span"+I+"'

}
}
// - End of JavaScript - -->
</script>
<div style="position: absolute; top: -25; left: 9; width: 717; height:
19">
</div>
第二步：把“onLoad="initiate()"”加在<body>标记里
例如：<body onLoad="initiate()">
