所以我有我的脚本运行,(你可以使用示例链接/图像来测试) 但我有一个问题。在计算了我的图像的长度之后,似乎 我的“过渡时期”在滑块开始回来/重复本身之前为 约为图像长度的三倍。我们可以使用样本 网址进行测试。Jquery滑块错误

<a class='wrapper' href='http://www.universallifechurchministers.org/images/big_image/ConanObrien.jpg' title="Conan O'Brien: TV host, comedian, writer, producer and performer."><img class='logo' alt="TV host, comedian, writer, producer and performer." id='conanobrien' src='http://www.universallifechurchministers.org/images/conan-obrien-sm.jpg' /><div class='long'>[.....]</div></a>

left:-632.914px看起来我的滑块在它再次开始滑动之前停下来。 我希望在最后一张图像 结束后立即重新开始,但无法弄清楚是什么阻止了它的实现?

此行下的“RTL”逻辑告诉元件,以保持滑动直到-632px(元件的宽度)。

//animate the el 
    el.animate({ 
     left: "-" + el.width() + "px" 
    }, time, "linear", function() { 

取下+“px”并改为使用' - ='!

//animate the el 
    el.animate({ 
     left: "-=" + el.width() 
    }, time, "linear", function() { 

我不明白你为什么采取这种方法。为什么不使用这个,它会在它离开“查看器”之前滑动它?

//animate the el 
    el.animate({ 
     left: ($('div#viewer').offset().left - $('div#container').outerWidth()) + "px" 
    }, time, "linear", function() { 

此外,为什么#container这么宽?为什么不让它保持内容的宽度?它真的需要和.wrapper一样宽吗?

我试图把你的代码,如果你看一路到最后,它做同样的事情,三倍的长度。 http://www.themonastery.org/jd/slider.php# – ehime

三倍的长度是什么?它正在移动#container的宽度,这是630像素宽? – Kato

现在看看我已经隐藏起来了,它仍然不会像最后一片叶子那样停下来,或者更好的是,它会以一个连续的圆圈运行。我尝试改变容器宽度,结果非常糟糕。 – ehime

这是一个连续循环滚动的例子。我认为你可能会从中提炼出一些想法,或者直接用它作为出发点;它解决了你所遇到的所有问题,因为我理解它们。我希望这有帮助!
