{ if(demo2.offsetWidth-demo.scrollLeft=0)
demo.scrollLeft-=demo1.offsetWidth
else{ demo.scrollLeft++ }
}
上面这段代码控制横向滚动条滚动
var MyMar=setInterval(Marquee,speed)
上面这段代码让浏览器每30毫秒调用一次Marquee函数
也就是让滚动条滚动
demo.onmouseover=function()
{
clearInterval(MyMar)
}
上面这段代码让 当鼠标移动到demo控件上时停止调用Marquee函数
也就是说,鼠标移动到demo控件上,滚动条不再滚动
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
上面这段代码 当鼠标从demo控件上移开始,继续每30毫秒调用一次Marquee函数
也就是让滚动条继续滚动
把下面这段代码加到BODY ........后面

楼主咋能这样说捏…………这是个很简答的东西…………
自己看最后一个javascript函数的注释,页面上的展示是一个DNA式的展示,其实就是两个楼主要求的东西向不同方向开始震动…………
很郁闷,20分钟完成功能,花了一个小时来优化了下代码…………

悬浮窗或者浮动窗。
浮动窗有两种方式,一种是浮动的层在网页上面任意飘动,一种是浮动的层跟随滚动条来回移动。这两种效果一般都可以利用javascript制作出来的。
网页上飘动的动态网页指网页是根据用户请求,由服务器上程序动态的生成的浮动窗。
