jQuery炫酷全屏3D焦点图动画

本文由码农网 – 小峰原创,转载请看清文末的转载要求,欢迎参与我们的付费投稿计划

这又是一款很不错的jQuery焦点图动画,它的特点是整个焦点图基本是全屏显示的,非常大气,而且图片的倾斜也给整个焦点图3D立体的视觉效果,而且焦点图的图片切换非常流畅,相当实用。

HTML代码:

<div class="wrapper">

</div>

<div id="pxs_container" class="pxs_container">
	<div class="pxs_bg">
		<div class="pxs_bg1"></div>
		<div class="pxs_bg2"></div>
		<div class="pxs_bg3"></div>
	</div>
	<div class="pxs_loading">Loading images...</div>
	<div class="pxs_slider_wrapper">
		<ul class="pxs_slider">
			<li><img src="images/1.jpg" alt="First Image" /></li>
			<li><img src="images/2.jpg" alt="Second Image" /></li>
			<li><img src="images/3.jpg" alt="Third Image" /></li>
			<li><img src="images/4.jpg" alt="Forth Image" /></li>
			<li><img src="images/5.jpg" alt="Fifth Image" /></li>
			<li><img src="images/6.jpg" alt="Sixth Image" /></li>
		</ul>
		<div class="pxs_navigation">
			<span class="pxs_next"></span>
			<span class="pxs_prev"></span>
		</div>
		<ul class="pxs_thumbnails">
			<li><img src="images/thumbs/1.jpg" alt="First Image" /></li>
			<li><img src="images/thumbs/2.jpg" alt="Second Image" /></li>
			<li><img src="images/thumbs/3.jpg" alt="Third Image" /></li>
			<li><img src="images/thumbs/4.jpg" alt="Forth Image" /></li>
			<li><img src="images/thumbs/5.jpg" alt="Fifth Image" /></li>
			<li><img src="images/thumbs/6.jpg" alt="Sixth Image" /></li>
		</ul>
	</div>
</div>

调用插件的JavaScript代码

$(function() {
	var $pxs_container	= $('#pxs_container');
	$pxs_container.parallaxSlider();
});
