javascript - 图像 slider 过渡时间

Question

我刚刚根据找到的教程创建了一个图像 slider 。我只是粘贴了一些我在网上找到的快速图片来测试它，但我问问题的原因是因为更改图像所需的时间差异很大。这将花费很长时间，然后它会开始每隔一两秒更改一次图像。如何使我的 slider 具有一致的滑动过渡。

最好发布我的网站，这样您就可以看到它在做什么。

我正在使用插件 javascript，所以代码是一堆。有没有办法添加我自己的代码，使相同的基本功能起作用，但质量更好？

Jquery:

Answer 1

像这样的事情:

r.startSlide = Math.floor(Math.random() * i.totalSlides)

是这里的问题吗，它是故意按原样编程的。

有更简单的 slider ，即使只有 css。

我有一个完全响应式的，如果您需要，请告诉我。
