<script defer>


var marquee1 = new Marquee("marqueediv")
marquee1.Direction = "top";
marquee1.Step = 1;
marquee1.Width = 760;
marquee1.Height = 52;
marquee1.Timer = 50;
marquee1.DelayTime = 10000;   
marquee1.WaitTime = 3000;
marquee1.ScrollStep = 52;
marquee1.Start();

简单拿上面的代码作个例子。上面实现的是上下滚动。第隔10秒向上滚动一个图片

要是想实现每隔1分钟向左右方向滚动一格。隔2分钟上下滚动一个格。
要怎么样才能实现。
请高手来帮忙解答一下。
