jQuery bgStretcher 背景圖片切換效果插件


偶爾發現了這么一個插件,很不錯的一個功能!

jQuery bgStretcher (Background Stretcher),可以為你的網頁添加多張背景圖,且多個背景圖能夠自動切換,同時背景圖大小可以自適應瀏覽器窗口的大小。背景圖的切換效果有淡入淡出,滾動,幻燈,其中選用滾動和幻燈時,可以選擇方向,上下左右,或者左上右下,右上左下。圖片切換順序也可以設置正向,反向或者隨機。

插件特點:
  腳本文件簡潔,設置簡單;

  支持所有新版瀏覽器;

  支持單張或者多張圖片。

插件使用:
  首先你要把插件先下載再說,插件包里已經包含了所需要的JS文件。
  然后,把下面的代碼插入到你網頁的<head>和</head>之間,這樣后面才能使用插件,注意代碼中的路徑,至於是相對路徑還是絕對路徑看你實際需要。

<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" />

接着把下面的代碼,插入到上面代碼之后,來初始化 bgStretcher 插件,要告知插件在哪個元素上起作用,同時可以配置插件的選項。同樣,注意代碼中的圖片路徑不要出錯。

<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>

該插件不只是用於整個網頁背景,還可以用於某個網頁元素,當然,起碼這個元素能設置背景,比如DIV之類等等。選擇網頁元素是通過ID或者Class來的,應為BODY這個元素名是網頁里唯一的元素名,也就是給整個網頁設置背景。如果是給頁面某一個DIV塊設置背景,那你需要給這個DIV定義一個ID或者知道它的樣式Class名也行,ID和Class名最好是唯一的,要不然效果很驚人。

<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>
