Question

我有这个脚本，从底部到顶部垂直滚动图像，除了一件事，它的效果还不错。我希望这个滚动是无限的，而不是每次帧都为空时重新启动。换句话说，我不希望它在任何时候都是空的。

你们认为这是可能的吗？这是代码（我知道脚本非常糟糕，但我已经尝试了很多，这只是一个为我做的技巧）：

<BODY BGCOLOR="#FFFFFF" TEXT="#000000" onMouseover="scrollspeed=(current/2)" onMouseout="scrollspeed=current" OnLoad="NewsScrollStart();">

<div id="NewsDiv">

尝试在您滚动的图像后立即放置图像副本并滚动两者。一旦第一张图像完全离开屏幕并且复制在屏幕上，将第一张图像放在复印件后面并继续滚动，直到复印件关闭屏幕并且原件完全在屏幕上。如果你不断重复这个，你应该得到无限滚动图像的错觉。
