如何解决有没有办法在 HTML 表格上自定义选取框以减少滚动延迟?
我从 API 获取数据,我想将其显示在表格上。但是,此表格具有选框滚动功能。
挑战是 scroll delay
,我想显示记录,然后延迟 3 秒,然后再次开始循环。
目前,延迟大约在 80 秒后开始,猜猜这是默认值?
等等,我知道选框已被弃用,但是,它适用于这种情况。
有人知道怎么做吗?

解决方法
没有 css 属性可以在迭代之间延迟。所以我们可以给出动画本身的差距。这是数学:
(延迟 ÷ 总时间)*100 = 开始百分比
您想延迟 3 秒,所以我们可以在 (3÷Total Time)*100 处开始我们的动画。
我举了一个总时间为 9 秒的例子。 我们将在 ((3÷9)*100) = 33%
处开始动画这会使动画延迟 3 秒,完成动画需要 6 秒。
代码如下:
.marquee {
top: 100%;
position: relative;
box-sizing: border-box;
animation: marquee 9s linear infinite;
}
.marquee:hover {
animation-play-state: paused;
}
@keyframes marquee {
0% {
top: 100%
}
33% {
top: 100%
}
100% {
top: -100%;
}
}
,
实际上,没有设置下一次迭代延迟的选项,但我们可以通过CSS中的小变化来管理它,如下所示,请尝试使用这个CSS
.marquee {
top: 6em;
position: relative;
box-sizing: border-box;
animation: marquee 20s linear 0s infinite;
}
.marquee:hover {
animation-play-state: paused;
}
@keyframes marquee {
0% {
top: 30em;
}
100% {
top: -30em;
}
}
