This article mainly introduces the method of using JavaScript script to achieve scrolling effect, that is, a bulletin board display-like effect. Friends who need it can refer to it

Many friends who make web pages often make bulletin boards and information Window, I often worry about realizing the scrolling display of the whole page and images. Don't worry, here is a simple method to realize the scrolling display. We did not use Java's .class program to implement it, nor was it a dynamic DHTML language. We just made full use of some functions of the JavaScript script language and wrote some short JavaScript script language to achieve this function.

The original code is as follows: 

<html>
　　<head>
　　<script language="Javascript">
　　<!--//防止错误显示
　　locate=0;
　　function my_scroller()
　　{
　　 if (locate !=400 )
　　{
　　 locate++;//值增加
　　 scroll(0,locate);
　　 clearTimeout(timer);
　　 var timer = setTimeout("my_scroller()",2);//控制滚动时间
　　 timer;
　　}
　　}
　　 -->
　　</script>
　　</head>
　　<body OnLoad="my_scroller()">

　　</html>

You can control the length of the displayed page by changing the value of Locate (the original code is Locate!= 400); You can modify "2" in "SetTimeout("Scroller()",2);" to change the scrolling speed. You can try making some adjustments separately. After the program is written and saved, it must be debugged on the PII PWS4.0 IE5 platform.
