滚动文字新闻的制作

新老客户大回馈,云服务器低至5折

一句一句话地显示出来,有点类似于跑马灯效果,文字效果的突出点比较明显,推荐使用。

制作方法:
将下面的代码复制到<body>~</body>里
<script language=JavaScript1.2>

//设置下面的参数(宽度,高度和背景色)可以得到不同的显示效果;
var scrollerwidth=500
var scrollerheight=100
var scrollerbgcolor=''

//下面的参数,不想使用背景图的话设为空;
var scrollerbackground=''

//下面的参数设置显示内容,可以使用HTML语法改变字体,大小和颜色及连接等;
var messages=new Array()
messages[0]="::::::::::::::::::::: 示例滚动新闻 :::::::::::::::::::::"
messages[1]="<a href='javascript:void(0)'>新奥特真三维虚拟演播室系统顺利通过广电总局检测</a>"
messages[2]="<a href='javascript:void(0)'>新奥特参加2001年江苏广播电视暨网络设备展览会成功 </a>"
messages[3]="<a href='javascript:void(0)'>九运组委会致函感谢新奥特提供电视字幕,为九运作出重要贡献</a>"

///////下面的代码不要改变//////

if (messages.length>1)

</script>
注意:在message[xxx]中不能含有空格,如下:
messages[1]="<table border=0><tr valign=top><td width=80>「 2001/10/26 」</td><td width=10></td><td>服务器现在真的是怪怪的,刚刚还用了新的地址了,一会儿又变<br>成了现在的这个了,真是让我干着急,真对不起大家啊!</td></tr></table>"
