使用动态生成在屏幕上和屏幕外动画 SVG 对象
Animating SVG objects on and off screen, with dynamic generation
我正在尝试使用我拥有的 SVG 对象创建动画,单行中的每个单独的 SVG 矩形都以向上或向下滚动的方式进行动画处理。我正在努力寻找学习如何执行此操作的资源以及实际实现此功能的最佳方法。
我想我还需要动态生成元素,这样在退出和进入屏幕时,矩形中永远不会有间隙。

好主意!这是一种方法。此版本使用 SMIL 动画。反向运动有点麻烦,可能有更好的方法来实现它。
它的基本工作原理:我将矩形放在 0,0 处并将它们向右移动。
我计算一个矩形需要移动多长时间它自己的长度(+两个矩形之间的space)然后将动画的开始时间设置为与其位置对应的负值,以便它到达正确的位置时间 0s.
如果您有任何问题,请尽管提问,我会修改答案以阐明其工作原理...希望对您有所帮助
