我正在尝试修改 Coda-Slider 2.0 (http://www.ndoherty.biz/tag/coda-slider/) 以使用基于百分比的宽度，而不是硬编码的像素宽度，以允许流体调整大小。当我尝试回到面板 1 时，除了 IE7 中的一个小故障（Firefox 没有表现出这种行为）之外，我已经让它工作得非常好。
当我运行 coda-slider 2.0 附带的默认 index.html 时，在 IE7 中一切正常。然后，我将图像替换为默认文本，并且效果也很好。然后我更改了 CSS 和 JS 以使用百分比宽度 - 这很好用，除了当我尝试返回第一个面板时 - 当我这样做时，比如说，从面板 4，而不是平滑地动画回到面板 1 视图立即跳到面板 1 和面板 2 之间的中间，然后动画回到面板 1。
这可以在我设置的测试站点上看到：

我正在使用的修改后的 Coda-Slider JS 文件的来源如下。请注意，我删除了所有不必要的代码以简化调试。
问题与这条线有关：
offset = - (panelWidth*z) + "%";
我想也许动画不喜欢将“0%”作为值输入，所以我尝试在选择面板 1 时输入“0”和“0px” - 结果相同。最终结果是正确的 - 最终 div 正确定位在 margin-left: 0，但我不知道为什么在这样做之前它会跳到面板 1 和 2 之间的中间位置。（面板 4 到 3 或 2 的动画效果很好）。我尝试使用 'left' 而不是 'margin-left' 得到相同的结果。
错误还是愚蠢的，被忽视的错误？任何意见是极大的赞赏！！
