猫头鹰传送带，到达第一个/最后一个项目后导航被禁用 [英] Owl Carousel, navigation disabled after reaching first/last item

问题描述

我正在尝试将猫头鹰轮播用于我的网站.我想在到达第一项/最后一项后禁用导航，例如，在导航中添加"disabled"类，然后通过CSS禁用它.是否有可能?

我的代码

 $(document).ready(function() {
  var owl = $("#owl-demo");
  owl.owlCarousel({
    rewindNav : false,	
    pagination : false,        
    items : 4
  });
  // Custom Navigation Events
  $(".next").click(function(){
    owl.trigger('owl.next');
  })
  $(".prev").click(function(){
    owl.trigger('owl.prev');
  })
}); 

 .item { background: #e5e5e5; margin: 10px}
.btn { background: #bd0000; color: #fff; padding: 5px 10px; cursor: pointer} 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://owlgraphic.com/owlcarousel/owl-carousel/owl.carousel.js"></script>
<link href="http://owlgraphic.com/owlcarousel/owl-carousel/owl.carousel.css" rel="stylesheet" />

<div id="owl-demo" class="owl-carousel owl-theme">
  <div class="item"><h1>1</h1></div>
  <div class="item"><h1>2</h1></div>
  <div class="item"><h1>3</h1></div>
  <div class="item"><h1>4</h1></div>
  <div class="item"><h1>5</h1></div>
  <div class="item"><h1>6</h1></div>
  <div class="item"><h1>7</h1></div>
  <div class="item"><h1>8</h1></div>
  <div class="item"><h1>9</h1></div>
  <div class="item"><h1>10</h1></div>
</div>

<div class="customNavigation">
  <a class="btn prev">Previous</a>
  <a class="btn next">Next</a>
</div>

解决方案

您可以将callbak afterAction和自定义控件一起使用

afterAction: function(){
  if ( this.itemsAmount > this.visibleItems.length ) {
    $('.next').show();
    $('.prev').show();

    $('.next').removeClass('disabled');
    $('.prev').removeClass('disabled');
    if ( this.currentItem == 0 ) {
      $('.prev').addClass('disabled');
    }
    if ( this.currentItem == this.maximumItem ) {
      $('.next').addClass('disabled');
    }

  } else {
    $('.next').hide();
    $('.prev').hide();
  }
}

解决方案

You can use callbak afterAction and with your custom controls

afterAction: function(){
  if ( this.itemsAmount > this.visibleItems.length ) {
    $('.next').show();
    $('.prev').show();

    $('.next').removeClass('disabled');
    $('.prev').removeClass('disabled');
    if ( this.currentItem == 0 ) {
      $('.prev').addClass('disabled');
    }
    if ( this.currentItem == this.maximumItem ) {
      $('.next').addClass('disabled');
    }

  } else {
    $('.next').hide();
    $('.prev').hide();
  }
}
