使用 owlcarousel2 进行幻灯片放映，为每张幻灯片设置移动

Question

我用 owlcarousel2 库创建了一个幻灯片放映，我想为每张幻灯片设置一个不同的动作出现在屏幕上。

例如，现在所有幻灯片都从右到左出现在屏幕上，就像正常的幻灯片放映一样。是否可以为每张幻灯片设置不同的外观移动，比如一些从左到右，另一些从右到左？

这是我的代码：

<section class="welcome_area" id="home">
    <div class="welcome_slides">
         <div class="single_slide">
            <div class="slide_text">
                <div class="table">
                    <div class="table_cell">
                        <center><img src="img/Oregon_Duck_website.gif" /></center>
                    </div>
                </div>
            </div>               
        </div>

        <!-- Slide -->
        <div class="single_slide">
            <div class="slide_text">
                <div class="table">
                    <div class="table_cell">
                        <center><img src="img/Oregon_Football_1_Black-Gray-Yellow.gif" /></center>
                    </div>
                </div>
            </div>               
        </div>
      </div>
</section>

和 js:

 if ($.fn.owlCarousel) {
    $(".welcome_slides").owlCarousel({
        items: 1,
        margin: 0,
        loop: true,
        nav: true,
        navText: ['<i class="fa fa-chevron-left" aria-hidden="true"></i>', '<i class="fa fa-chevron-right" aria-hidden="true"></i>'],
        dots: false,
        autoplay: true,
        autoplayTimeout: 7000,
        smartSpeed: 500,
        autoplayHoverPause: false
    });
}

Answer 1

您需要做 2 件主要事情：

在您的页面中包含 animate.css。

从 animate.css

提供的动画数组创建自定义函数 select

function getRandomAnimation() {
    var animationList = ['bounce', 'zoomIn', 'flipInX', 'flash', 'pulse', 'rubberBand', 'jello'];
    return animationList[Math.floor(Math.random() * animationList.length)];
}

一旦你完成了这两项设置，你只需要初始化 owl carousel 并设置 animateOut 和 animateIn 以从 getRandomAnimation() 函数中获取随机值。

  var owl = $('.owl-carousel');

  owl.owlCarousel({
    animateOut: getRandomAnimation,
    animateIn: getRandomAnimation,
    items: 1,
    margin: 30,
    stagePadding: 30,
    smartSpeed: 450,
    autoplay: true,
    autoplayTimeout: 2000
  });

在下面的示例中，我创建了一个自动播放设置为 2 秒的随机幻灯片动画，只是为了向您展示每张幻灯片都在选择不同的动画。

示例：

$(document).ready(function() {


  var owl = $('.owl-carousel');

  //init default carousel
  owl.owlCarousel({
    animateOut: getRandomAnimation,
    animateIn: getRandomAnimation,
    items: 1,
    margin: 30,
    stagePadding: 30,
    smartSpeed: 450,
    autoplay: true,
    autoplayTimeout: 2000
  });

 

  function getRandomAnimation() {
    var animationList = ['bounce', 'zoomIn', 'flipInX', 'flash', 'pulse', 'rubberBand', 'jello'];
    return animationList[Math.floor(Math.random() * animationList.length)];
  }

});

.owl-carousel {
  max-width: 300px;
}
