Javascript不是我的强项,我目前正在尝试修改教程中的图像滚动器构建一个找到here的jQuery Image Scroller。
我主要使用它,但是在重置之前图像滚动整个过程留下了大约6秒左右的空白区域。我想要尝试做的是,当第一个显示最后一个图像时,新循环开始了吗?
这是我的代码(基于教程)
<div id="outerContainer">
<div id="imageScroller">
<div id="viewer" class="js-disabled">
<img src="http://localhost:8888/ribbon/data/uploads/slider/imageScrollerBG.png" style="position:relative;display:block;float:left; z-index:10;">
<a class="wrapper" href="#nogo" title="img1"><img class="logo" id="01" src="http://localhost:8888/ribbon/data/uploads/slider/01.jpg" alt="01"></a>
<a class="wrapper" href="#nogo" title="img2"><img class="logo" id="02" src="http://localhost:8888/ribbon/data/uploads/slider/02.jpg" alt="02"></a>
<a class="wrapper" href="#nogo" title="img3"><img class="logo" id="03" src="http://localhost:8888/ribbon/data/uploads/slider/03.jpg" alt="03"></a>
<a class="wrapper" href="#nogo" title="img4"><img class="logo" id="04" src="http://localhost:8888/ribbon/data/uploads/slider/04.jpg" alt="04"></a>
<a class="wrapper" href="#nogo" title="img5"><img class="logo" id="05" src="http://localhost:8888/ribbon/data/uploads/slider/05.jpg" alt="05"></a>

和css
.js-disabled img { width:100px; height:100px; display:block; float:left; margin:30px 0 0; }
#outerContainer { width:900px; height:110px; margin:auto; margin-bottom:11px; margin- top:-8px; position:relative; }
#imageScroller { width:900px; height:110px; position:relative; background:#fff url(images/imageScrollerBG.png) no-repeat; }
#viewer { width:900px; height:110px; overflow:hidden; margin:auto; position:relative; top:10px; }
#imageScroller a:active, #imageScroller a:visited { color:#fff; }
#imageScroller a img { border:0; }
非常感谢任何帮助。

这段代码的工作原理。教程页面的演示也是如此。
我认为没有办法解决这个问题,这不会涉及重写大部分代码。
如果您不关心使用此代码,我建议您尝试使用另一个插件:
