所以我有我的脚本运行,(您可以使用示例链接/图像进行测试)但我有个问题。在计算了我的图像长度之后,似乎在滑块开始返回/重复之前,我的"过渡时期"是大约是图像长度的三倍。我们可以用样本来检验url。

left: -632.914px似乎是我的滑块在再次开始滑动之前停止的位置。我想让它在最后一张图片结束后立即重新开始,但不知道是什么阻止了它这样做?

在"rtl"逻辑下的这一行告诉元素保持滑动直到-632px(元素的宽度)。
//animate the el
el.animate({
left: "-" + el.width() + "px"
}, time, "linear", function() {
去掉+ "px",用'-='代替!
//animate the el
el.animate({
left: "-=" + el.width()
}, time, "linear", function() {
我真的不明白你为什么要采取这种方法。为什么不直接使用这个,它可以滑动它直到离开"查看器"?
//animate the el
el.animate({
left: ($('div#viewer').offset().left - $('div#container').outerWidth()) + "px"
}, time, "linear", function() {
还有,为什么#container这么宽?为什么不让它保持内容的宽度?它真的需要像。wrapper那么宽吗?
下面是一个连续循环滚动条的示例。我认为你可以从中汲取灵感,或者直接将其作为起点;就我所知,它解决了你所有的问题。我希望这对你有帮助!
