分享一个jquery的图片放大预览插件:cloud-zoom.
部署步骤:
1.加载jquery-1.4.js 和 cloud-zoom.1.0.2.min.js
2.加入样式表(DEMO中<style>部分)
3.为需要放大预览效果的缩略图添加超链接<a>并将类命名为”cloud-zoom” class=”cloud-zoom”
4.在超链接<a>的rel属性中加入需要的参数实现不同的效果
实例:
<a href=”images/大图.jpg” class=”cloud-zoom” rel=”position:’inside’ ,showTitle:false, adjustX:-2, adjustY:-2″><img src=”images/缩略图.jpg” title=”iinterest” /></a>
