jQuery bgStretcher 背景图片切换效果插件

偶尔发现了这么一个插件,很不错的一个功能!

jQuery bgStretcher (Background Stretcher),可以为你的网页添加多张背景图,且多个背景图能够自动切换,同时背景图大小可以自适应浏览器窗口的大小。背景图的切换效果有淡入淡出,滚动,幻灯,其中选用滚动和幻灯时,可以选择方向,上下左右,或者左上右下,右上左下。图片切换顺序也可以设置正向,反向或者随机。

插件特点:
  脚本文件简洁,设置简单;

  支持所有新版浏览器;

  支持单张或者多张图片。

插件使用:
  首先你要把插件先下载再说,插件包里已经包含了所需要的JS文件。
  然后,把下面的代码插入到你网页的<head>和</head>之间,这样后面才能使用插件,注意代码中的路径,至于是相对路径还是绝对路径看你实际需要。

<script type="text/javascript" src="../jquery-1.5.2.min.js"></script>
<script type="text/javascript" src="../bgstretcher.js"></script>
<link rel="stylesheet" href="../bgstretcher.css" />

接着把下面的代码,插入到上面代码之后,来初始化 bgStretcher 插件,要告知插件在哪个元素上起作用,同时可以配置插件的选项。同样,注意代码中的图片路径不要出错。

<script type="text/javascript">
$(document).ready(function(){
//  Initialize Backgound Stretcher
$('BODY').bgStretcher({
images: ['images/sample-1.jpg', 'images/sample-2.jpg', 'images/sample-3.jpg', 'images/sample-4.jpg'], imageWidth: 1024, imageHeight: 768
});
});
</script>

该插件不只是用于整个网页背景,还可以用于某个网页元素,当然,起码这个元素能设置背景,比如DIV之类等等。选择网页元素是通过ID或者Class来的,应为BODY这个元素名是网页里唯一的元素名,也就是给整个网页设置背景。如果是给页面某一个DIV块设置背景,那你需要给这个DIV定义一个ID或者知道它的样式Class名也行,ID和Class名最好是唯一的,要不然效果很惊人。

<script type="text/javascript">
$(document).ready(function(){
//  Initialize Backgound Stretcher
$('.classname-of-div').bgStretcher({
images: ['images/sample-1.jpg', 'images/sample-2.jpg', 'images/sample-3.jpg', 'images/sample-4.jpg'], imageWidth: 1024, imageHeight: 768
});
});
</script>


<body>
<div class="classname-of-div">
Your content goes here...
</div>
</body>
