参数含义:

display_num:显示元素的数量,几张图片

move:单击左右控制键时,移动的元素个数,此处为移动2张图片

prev_image:上一元素按钮图片

next_image:下一元素按钮图片

margin:图片之间的间隙,一般设为10px

auto:自动滚动效果

controls:是否显示左右控制按钮,此处为false,表示不显示左右控制按钮

auto_hover:鼠标悬停到轮播区域时,是否停止图片轮播

BxCarousel使用和配置

首先HTML代码需要符合以下格式

<ul>
<li>first piece of content</li>
<li>second piece of content</li>
<li>third piece of content</li>
<li>fourth piece of content</li>
<li>bxCarousel can accept an unlimited number of elements</li>
</ul>

jQuery代码需要符合以下格式:
$(document).ready(function(){
$('ul').bxCarousel({
display_num: 4, // number of elements to be visible
move: 4, // number of elements to the shift the slides
speed: 500, // number in milliseconds it takes to finish slide animation
margin:0, // right margin to be applied to each <li> element (in pixels, although do not include "px")
auto: false, // automatically play slides without a user click
auto_interval: 2000, // the amount of time in milliseconds between each auto animation
auto_dir: 'next', // direction of auto slideshow (options: 'next', 'prev')
auto_hover: false, // determines if the slideshow will stop when user hovers over slideshow
next_text: 'next', // text to be used for the 'next' control
next_image: '', // image to be used for the 'next' control
prev_text: 'prev', // text to be used for the 'prev' control
prev_image: '', // image to be used for the 'prev' control
controls: true // determines if controls will be displayed
});

});

div.bx_container和div.bx_wrap等html元素是js生成加上的,在使用bxCarousel插件时,为了达到视觉美感,要记得为div.bx_container和div.bx_wrap及其内部子元素设定需要的CSS Style。
还有注意的是,
bxCarousel是个无限循环机制,不停的点击next按钮看看html发生了什么变化!!
bxCarousel不只针对图片,对其他任何html元素均起作用。
如果开启auto属性,注意一定要保证speed属性值小于持续时间。

实例代码:

<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" >
<title></title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="js/bxCarousel.js"></script>
<script type="text/javascript">
jQuery(function(){
	jQuery('#demo1').bxCarousel({
		display_num: 4, //
		move: 1, 
		auto: true, 
		controls: false, //此处为false,表示不显示左右箭头控制按钮
		margin: 10,
		auto_hover: true //鼠标悬停到轮播区域时,是否停止图片轮播
	});
	jQuery('#demo2').bxCarousel({
		display_num: 4, 
		move: 4,
		margin: 10 
	});
});
