bgStretcher 2011 (Background Stretcher)是一個jQuery的插件,能夠爲你的網頁添加多張背景圖,且多個背景圖可以自動切換,同時背景圖大小能夠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,能夠選擇方向,上下左右,或者左上右下,右上左下。圖片切換順序也能夠設置正向,反向或者隨機。更多選項就看你本身慢慢研究了。 插件特色:css
腳本文件簡潔,設置簡單;支持全部新版瀏覽器;支持單張或者多張圖片。
插件使用:
首先,你固然要把插件先下載再說,插件包裏已經包含了所須要的JS文件。
而後,把下面的代碼插入到你網頁的<head>和</head>之間,這樣後面才能使用插件,注意代碼中的路徑,至因而相對路徑仍是絕對路徑看你實際須要。
1 |
< link rel = "stylesheet" type = "text/css" href = "./main.css" /> |
2 |
< link rel = "stylesheet" type = "text/css" href = "../bgstretcher.css" /> |
3 |
< script type = "text/javascript" src = "../jquery-1.5.2.min.js" ></ script > |
4 |
< script type = "text/javascript" src = "../bgstretcher.js" ></ script > |
接着把下面的代碼,插入到上面代碼以後,來初始化 bgStretcher 插件,要告知插件在哪一個元素上起做用,同時能夠配置插件的選項。一樣,注意代碼中的圖片路徑不要出錯。
01 |
< script type = "text/javascript" > |
02 |
$(document).ready(function(){ |
04 |
// Initialize Backgound Stretcher |
05 |
$('.demoo').bgStretcher({ |
06 |
images: ['images/sample-1.jpg', 'images/sample-2.jpg', 'images/sample-3.jpg', 'images/sample-4.jpg', 'images/sample-5.jpg', 'images/sample-6.jpg'], |
11 |
transitionEffect: 'fade', |
12 |
sequenceMode: 'normal', |
該插件不僅是用於整個網頁背景哦,還能夠用於某個網頁元素,固然,起碼這個元素能設置背景,好比DIV之類等等。選擇網頁元素是經過ID或者Class來的,應爲BODY這個元素名是網頁裏惟一的元素名,也就是給整個網頁設置背景。若是是給頁面某一個DIV塊設置背景,那你須要給這個DIV定義一個ID或者知道它的樣式Class名也行,ID和Class名最好是惟一的,要否則效果很驚人。
