jQuery插件Step Carousel Viewer实现Javascript图片滑动旋转效果

Google AD

需要将产品图片或相片等实现Javascript图片滑动旋转Animation效果，能自动播放图片或鼠标控制播放图片，图片固定的滑动在指定的区域内，类似动画播放，使用jQuery插件Step Carousel Viewer可实现该功能，而且使用简单，Step Carousel Viewer中文大概是按步旋转阅读，意思是说每张图片一张一张旋转阅读，效果：

<script type="text/javascript">
// For instructions how how to modify go to this URL
// http://www.dynamicdrive.com/dynamicindex4/stepcarousel.htm
stepcarousel.setup({
	galleryid: 'mygallery', //id of carousel DIV
	beltclass: 'belt', //class of inner "belt" DIV containing all the panel DIVs
	panelclass: 'panel', //class of panel DIVs each holding content
	autostep: {enable:true, moveby:1, pause:2000},
	panelbehavior: {speed:500, wraparound:true, persist:true},
	defaultbuttons: {enable: false, moveby: 1, leftnav: ['../317e0s5.gif', -5, 80], rightnav: ['../33o7di8.gif', -20, 80]},
	statusvars: ['statusA', 'statusB', 'statusC'], //register 3 variables that contain current panel (start), current panel (last), and total panels
	contenttype: ['inline'] //content setting ['inline'] or ['external', 'path_to_external_file']
})
</script>

1，galleryid 图片滑动旋转外层的DIV，如：mygallery
2，beltclass 图片滑动旋转中间层的Class，如：belt
3，panelclass 图片滑动旋转图片显示层的Class，如：panel
4，autostep 自动播放设置
5，panelbehavior 图片滑动效果
6，defaultbuttons 默认按钮，左导航按钮，如：biuuu_left.gif，右导航按钮，如：biuuu_right.gif
7，statusvars 注册三个变量，包含当前显示start图片数，当前last图片数和总图片数
8，contenttype 内容设置，可选inline或external

 
<div id="slider_nav">
<div style="float:left;"> <a href="javascript:stepcarousel.stepBy('mygallery',%20-1)"><img src="index_files/arr-left.png" alt="Back"></a> </div>
<div style="float:right;"> <a href="javascript:stepcarousel.stepBy('mygallery',%201)"><img src="index_files/arr-right.png" alt="Forward"></a> </div>
</div>

1，当前图片数<span id=”statusA”></span> 总图片数<span id=”statusC”></span>
2，往最后图片stepcarousel.stepBy(‘mygallery’, -1)
3，往开始图片stepcarousel.stepTo(‘mygallery’, 1)
4，向前一张图片stepcarousel.stepBy(‘mygallery’, 1)
5，向前二张图片stepcarousel.stepBy(‘mygallery’, 2)

实现由文字链接控制当前图片滑动，方法stepcarousel.stepBy()和stepcarousel.stepTo()上面mygallery表示图片滑动旋转外层DIV的ID，直接调用即可实现。

In other words, no more white space at the end. //2) Adds ability for Carousel to auto rotate dictated by the new parameter: autostep: {enable:true, moveby:1, pause:3000} //2i) During Auto Rotate, Carousel pauses onMouseover, resumes onMouseout.
