快捷導(dǎo)航

基于jQuery的仿flash的廣告輪播

更新時(shí)間：2010年11月05日 22:39:14 作者：

很多網(wǎng)站的首頁(yè)都有廣告輪播，今天閑來(lái)看了一網(wǎng)站的首頁(yè)廣告輪播方式，是通過(guò) jQuery的blockSlide插件實(shí)現(xiàn)的，然后自己測(cè)試了一下，很好。

整個(gè)頁(yè)面如下：

<script src="Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></script> 
<script src="_Template/js/blockSlide.js" type="text/javascript"></script> 
<style type="text/css"> 
div#imgADPlayer 
{ 
margin: auto; 
margin-bottom: 4px; 
width: 960px; 
height: 120px; 
background: url(../images/photo_01.jpg) left top no-repeat; 
padding: 0px; 
border: none; 
clear: both; 
position: relative; 
} 
div#imgADPlayer .smask 
{ 
position: absolute; 
left: 0px; 
top: 0px; 
} 
</style> 
</head> 
<body> 
<!-- 滾動(dòng)圖片開(kāi)始 --> 
<div id="imgADPlayer"> 
<div id="AdTop"> 
<div id="myjQueryContent"> 
<div> 
<a href="javascript:void(0)"> 
<img src="_Template/images/photo_01.jpg" alt="" /></a></div> 
<div class="smask">

<div class="smask">

<img src="_Template/images/photo_04.jpg" alt="" /></a></div> 
</div> 
<div id="flow"> 
</div> 
</div> 
<script type="text/javascript" language="javascript"> 
$(document).ready(function () { 
$("#AdTop").blockSlide({ 
speed: "normal", 
num: 4, 
timer: 3000, 
flowSpeed: 300 
}); 
}); 
</script> 
</div> 
<!--滾動(dòng)圖片結(jié)束 --> 
</body> 
</html> 

注釋：
speed：圖片輪播速度
num：圖片數(shù)量
timer：自動(dòng)輪播的時(shí)間間隔，定時(shí)器；
flowSpeed：是滑塊移動(dòng)的速速度

blockSlide插件源碼如下：

復(fù)制代碼代碼如下:

 
/** 
* @author huajianhuakai */ 
(function($) 
{ 
$.fn.blockSlide = function(settings) 
{ 
settings = jQuery.extend({ 
speed: "normal", 
num: 4, 
timer: 1000, 
flowSpeed: 300 
}, settings); 
return this.each(function() 
{ 
$.fn.blockSlide.scllor($(this), settings); 
}); 
}; 
$.fn.blockSlide.scllor = function($this, settings) 
{ 
var index = 0; 
var imgScllor = $("div:eq(0)>div", $this); 
var timerID; 
//自動(dòng)播放 
var MyTime = setInterval(function() 
{ 
ShowjQueryFlash(index); 
index++; 
if (index == settings.num) 
index = 0; 
}, settings.timer); 
var ShowjQueryFlash = function(i) 
{ 
$(imgScllor).eq(i).animate({ opacity: 1 }, settings.speed).css({ "z-index": "100" }).siblings().animate({ opacity: 0 }, settings.speed).css({ "z-index": "0" }); 
} 
} 
})(jQuery);
