jQuery和CSS3炫酷弹性过渡全屏翻页特效

这是一款使用jQuery和CSS3来制作炫酷弹性过渡全屏翻页特效。该翻页特效可以通过点击导航按钮来全屏切换页面，在页面切换时，整个页面以弹性变形的方式过渡到下一个页面，效果非常的炫酷。

使用方法

HTML结构

该全屏翻页特效的HTML结构如下：

<div class="page-slider">
  <div class="prev-btn">Up</div>
  <div class="next-btn">Down</div>
  <div class="nav-dots">
    <div data-slide="1" class="nav-dot">
    </div>
    <div data-slide="2" class="nav-dot">
    </div>
    <div data-slide="3" class="nav-dot">
    </div>
  </div>
  <div data-slide="1" class="panel">
    <div id="layer-1" class="trans-layer"></div>
    <section id="section-1" class="section">
      <div class="section-content">
        <h1>Vertical slider</h1>
      </div>
    </section>
  </div>
  <div data-slide="2" class="panel">
    <div id="layer-2" class="trans-layer"></div>
    <section id="section-2" class="section">
      <div class="section-content">
        <h1>Section 2</h1>
      </div>
    </section>
  </div>
  <div data-slide="3" class="panel">
    <div id="layer-3" class="trans-layer"></div>
    <section id="section-3" class="section">
      <div class="section-content">
        <h1>Section 3</h1>
      </div>
    </section>
  </div>
</div>          
                

CSS样式

页面的主要CSS样式如下：

.page-slider {
  position: relative;
  top: 0;
  width: 100vw;
  height: 100vh;
  max-width: 100%;
  max-height: 100%;
  background: deepskyblue;
  overflow: hidden;
}

.panel {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  margin: auto;
}

.panel._active { z-index: 10; }

.section-content {
  display: flex;
  flex-flow: column;
  width: 100%;
  height: 100%;
  justify-content: center;
  align-items: center;
  color: #fff;
  font-family: arial;
  text-transform: uppercase;
  opacity: 0;
  transform: translateY(30px);
  transition: all 500ms ease;
  transition-delay: 0s;
}

.section {
  transform: translateY(100%);
  transition: all 500ms ease-in-out;
  transition-delay: 0ms;
  background: #343434;
}             
                

两个页面之间的弹性过渡动画效果CSS样式如下：

.trans-layer, .section {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
}

.trans-layer {
  background: #000;
  transform: translateY(-100%) skew(0) rotate(0) scale(2);
  border-radius: 50%;
  transition: all 500ms ease-in-out;
  transition-delay: 500ms;
}

._active .trans-layer {
  transform: translateY(0) skew(0) rotate(0) scale(2);
  transition-delay: 0ms;
}

._active .section {
  transform: translateY(0);
  transition-delay: 500ms;
}

._active .section-content {
  opacity: 1;
  transform: translateY(0px);
  transition-delay: 1000ms;
}                  
                

最后为圆点导航和箭头导航按钮设置样式：

.nav-dots {
  position: absolute;
  top: 50%;
  right: 10px;
  transform: translateY(-50%);
  z-index: 20;
  width: 40px;
}

.nav-dot {
  width: 10px;
  height: 10px;
  margin: 20px auto;
  border-radius: 50%;
  background: #fff;
  cursor: pointer;
  transition: all 300ms ease-out;
}

.nav-dot.active { background: red; }

.next-btn, .prev-btn {
  width: 30px;
  height: 30px;
  position: absolute;
  z-index: 20;
  border: 1px solid #fff;
  color: #fff;
  line-height: 30px;
  text-align: center;
  font-size: 24px;
  cursor: pointer;
}

.next-btn {
  bottom: 10px;
  right: 14px;
}

.prev-btn {
  top: 10px;
  right: 14px;
}            
                

初始化插件

在页面DOM元素加载完毕之后，可以通过下面的jQuery代码来初始化该全屏翻页特效。

$('.wrapper').each(function() {
      var $slider =  $(this);
      var numberOfSlides = $slider.find('.panel').length;
      
      $slider.find('.panel:eq(0)').addClass('_active');
      $slider.find('.nav-dot:eq(0)').addClass('active');
      
      var $activeSlide = $slider.find('.panel._active');
      var $nextBtn = $slider.find('.next-btn');
      var $prevBtn = $slider.find('.prev-btn');
      
      $('.nav-dot').on('click', function() {
        var slideToGo = $(this).data('slide');
        goToSlide(slideToGo);
      });

      $slider.on('slide.changed', function() {
        console.log('slide changed !');
        $('.nav-dot').removeClass('active');
        var $activeDot = $('.nav-dot[data-slide="'+$('.panel._active').data('slide')+'"]');
        $activeDot.addClass('active');
      });
      
      $nextBtn.on('click', function(event) {
        nextSlide();
      });
      
      $prevBtn.on('click', function(event) {
        prevSlide();
      });
      

      function nextSlide() {
        $activeSlide = $slider.find('.panel._active');
        var $nextSlide = $activeSlide.next('.panel');
        $activeSlide.removeClass('_active');
        $nextSlide.addClass('_active');
        
        
        var slideIndex = $slider.find('.panel._active').index('.panel');
        console.log(slideIndex);
        
        
        if(slideIndex >= numberOfSlides || slideIndex
