JS点击自动滚屏的问题

[go786]

我今天找了一个JS的点击自动滚屏，右键自动暂停的代码。但是发现只有在IE浏览器下右键才能暂停。在其他浏览器（包括IE内核的浏览器）下点击虽然可以滚屏，但是右键却无法暂停。希望高手能帮我修改一下。
http://www.7wind.net/wytx/ck/28.htm 这个是测试页面

下面是代码：

<script language="JavaScript"> 
function click() {
if (event.button==2) {
	if(document.all.auto.status==true){document.all.auto.status=false;alert("自动滚屏已经停止了！")}
	scroller();
	}
}
document.onmousedown=click

var position = 0; 
function scroller() {
if (document.all.auto.status==true){ 
	position++; 
	scroll(0,position); 
	clearTimeout(timer); 
	var timer = setTimeout("scroller()",50); 
	timer;
	}
else{
	clearTimeout(timer);
	}
} 
</script> 
<script language="JavaScript">
<!--
function MM_callJS(jsStr) { //v2.0
  return eval(jsStr)
}
//-->
</script>
<div align="right">
<input type="checkbox" name="auto" value="on" onClick="MM_callJS('scroller() ; ')" >自动滚屏(右键暂停)</div>

var currentpos,timer;
function initialize()
{
timer=setInterval("scrollwindow()",10);
}
function sc(){
clearInterval(timer);
}
function scrollwindow()
{
currentpos=document.body.scrollTop;
window.scroll(0,++currentpos);
if (currentpos != document.body.scrollTop)
sc();
}
document.onmousedown=sc
document.ondblclick=initialize

body改成documentElement IE FF通用

改为

："MM_callJS('scroller() ')"去掉分号

　制作时间:2006-08-29 (Ver 0.5)
　发布时间:2006-08-31 (Ver 0.8)
　更新时间:2007-12-28 (Ver 1.65)
　更新说明: + 加入功能 * 修正、完善
1.65.071228
* 横向、纵向滚动格式调整 (解决横向滚动换行的问题，无需特殊设置)
* 彻底解决由于IE问题导致上下滚动页面留白的问题 (本次更新主要解决此问题,感谢天上的书生参与测试)
1.6.070131
+ 禁止鼠标控制暂停或继续 (将第9个参数设置为-1或者动态赋值将ScrollSetp设置为-1)
+ 判断是否可以滚动 (若内容区域小于显示区域,则自动取消滚动)
+ 跳过初始化错误 (避免引起其它滚动的停止)
+ 默认值 (除容器ID必选外，其他参数均可根据情况进行选择设置)
+ 参数动态赋值 (方向可用英文表示top|up|bottom|down|left|right,使其更直观、方便)
* 文字滚动不准确 (本次更新主要目的解决此Bug,感谢周珺参与测试)
1.4.061211
+ 鼠标悬停改变滚动方向 (鼠标悬停控制左右滚动)
* 由于文档下载过慢而导致获取的高度/宽度不准确
* 浏览器兼容问题 (IE、FF、Opera、NS、MYIE)
1.2.060922
+ 指定范围间歇滚动
* 程序调整
* 连续间歇滚动停止的错误

　应用说明:页面包含<script type="text/javascript" src="MSClass.js"></script>

创建实例:
//参数直接赋值法
new Marquee("marquee")
new Marquee("marquee","top")
......
new Marquee("marquee",0,1,760,52)
new Marquee("marquee","top",1,760,52,50,5000)
......
new Marquee("marquee",0,1,760,104,50,5000,3000,52)
new Marquee("marquee",null,null,760,104,null,5000,null,-1)

//参数动态赋值法
var marquee1 = new Marquee("marquee") *此参数必选
marquee1.Direction = "top"; 或者 marquee1.Direction = 0;
marquee1.Step = 1;
marquee1.Width = 760;
marquee1.Height = 52;
marquee1.Timer = 50;
marquee1.DelayTime = 5000;
marquee1.WaitTime = 3000;
marquee1.ScrollStep = 52;
marquee1.Start();

参数说明:
ID "marquee" 容器ID (必选)
Direction (0) 滚动方向 (可选,默认为0向上滚动) 可设置的值包括:0,1,2,3,"top","bottom","left","right" (0向上 1向下 2向左 3向右)
Step (1) 滚动的步长 (可选,默认值为2,数值越大,滚动越快)
Width (760) 容器可视宽度 (可选,默认值为容器初始设置的宽度)
Height (52) 容器可视高度 (可选,默认值为容器初始设置的高度)
Timer (50) 定时器 (可选,默认值为30,数值越小,滚动的速度越快,1000=1秒,建议不小于20)
DelayTime (5000) 间歇停顿延迟时间(可选,默认为0不停顿,1000=1秒)
WaitTime (3000) 开始时的等待时间(可选,默认或0为不等待,1000=1秒)
ScrollStep (52) 间歇滚动间距 (可选,默认为翻屏宽/高度,该数值与延迟均为0则为鼠标悬停控制,-1禁止鼠标控制)

document.all属性只有IE有。
试试这个：
<SCRIPT language=JavaScript>
var currentpos,timer;

function initialize()
{
timer=setInterval("scrollwindow()",10);
}
function sc(){
clearInterval(timer);
}
function scrollwindow()
{
currentpos=document.body.scrollTop;
window.scroll(0,++currentpos);
if(currentpos != document.body.scrollTop)sc();
}
document.onmousedown=sc
document.ondblclick=initialize
</script>

啊，好长的代码，有点晕！
