一句一句話地顯示出來,有點類似于跑馬燈效果,文字效果的突出點比較明顯,推薦使用。
制作方法:
將下面的代碼復制到<body>~</body>里
<script language=JavaScript1.2>
//設置下面的參數(寬度,高度和背景色)可以得到不同的顯示效果;
var scrollerwidth=500
var scrollerheight=100
var scrollerbgcolor=''
//下面的參數,不想使用背景圖的話設為空;
var scrollerbackground=''
//下面的參數設置顯示內容,可以使用HTML語法改變字體,大小和顏色及連接等;
var messages=new Array()
messages[0]="::::::::::::::::::::: 示例滾動新聞 :::::::::::::::::::::"
messages[1]="<a href='javascript:void(0)'>新奧特真三維虛擬演播室系統順利通過廣電總局檢測</a>"

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>服務器現在真的是怪怪的,剛剛還用了新的地址了,一會兒又變<br>成了現在的這個了,真是讓我干著急,真對不起大家??!</td></tr></table>"
正 確
messages[1]="<table border=0><tr valign=top><td width=80>「 2001/10/26 」</td>
<td width=10></td><td>服務器現在真的是怪怪的,剛剛還用了新的地址了,一會兒又變
<br>成了現在的這個了,真是讓我干著急,真對不起大家??!</td></tr></table>"
錯 誤
至此你就可以完成這個實例了。
