 歡迎光臨 
 實用的逐行文本滾動效果<br>
 滾動一行至另一行時有所停頓<br>
 希望大家喜歡，感覺挺簡潔的代碼<br>
 </div>
 <script>
 window.onload=function(){
 new Marquee(
 "scrollBox2", //容器ID<br>
 0, //向上滾動(0向上 1向下 2向左 3向右)<br>
 2, //滾動的步長<br>
 200, //容器可視寬度<br>
 , //容器可視高度<br>
 50, //定時器 數(shù)值越小，滾動的速度越快(1000=1秒,建議不小于20)<br>
 2000, //間歇停頓時間(0為不停頓,1000=1秒)<br>
 1000, //開始時的等待時間(0為不等待,1000=1秒)<br>
 //間歇滾動間距(可選)<br>
