一款由jquery实现的整屏切换特效

今天要为大家带来一款由jquery实现的整屏切换特效，在右侧有圆型小标，每点一个切换一屏。当然，你也可以滚动鼠标来切换页面。效果非常好。我们看下效果吧

html代码：

<div class="wrapper active-page4">
<div class="page page1">
<h2>
First page</h2>
</div>
<div class="page page2">
<h2>
Second page</h2>
</div>
<div class="page page3">
<h2>
Third page</h2>
</div>
<div class="page page4">
<h2>
Fourth page</h2>
</div>
</div>
<div class="nav-panel">
<div class="scroll-btn up">
</div>
<div class="scroll-btn down">
</div>
<nav>
<ul>
<li data-target="1" class="nav-btn nav-page1"></li>
<li data-target="2" class="nav-btn nav-page2"></li>
<li data-target="3" class="nav-btn nav-page3"></li>
<li data-target="4" class="nav-btn nav-page4 active"></li>
</ul>
</nav>
</div>
