使用猫头鹰轮播替换当前项目2

Question

如何用新物品替换/重建owl carousel物品？

描述

在许多情况下，例如当您从数据库中获取新数据时，您会在轮播中添加新数据，但在此示例中，我尝试将所有项目替换为新项目。

$('.owl-carousel').owlCarousel({
    loop:true,
    margin:10,
    nav:true
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.2.1/owl.carousel.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.2.1/assets/owl.carousel.min.css" />
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.2.1/assets/owl.theme.default.min.css" />
<div class="owl-carousel owl-theme">
    <div class="item">
      <h4>Old 1-1</h4></div>
    <div class="item">
      <h4>Old 2-1</h4></div>
    <div class="item">
      <h4>Old 3-1</h4></div>
    <div class="item">
      <h4>Old 4-1</h4></div>
  </div>

Answer 1

根据 Owl 轮播 2 文档，您可以使用 replace.owl.carousel 事件。

replace.owl.carousel

类型： triggerable参数：data

删除当前内容并添加参数中传递的新内容。

用法

首先，您需要使用触发器replace然后使用触发器附加新数据refresh。请勿使用destroy或re-initialize

示例 1/更新/替换

$('.owl-carousel').owlCarousel({
  loop: true,
  margin: 10,
  nav: true
});
$('#reb').click(function() {
  var html = '<div class="owl-item"><h4>1-2</h4></div><div class="item"><h4>2-2</h4></div><div class="item"><h4>3-2</h4></div><div class="item"><h4>4-2</h4></div><div class="item"><h4>2-2</h4></div>';
  $('.owl-carousel').trigger('replace.owl.carousel', html).trigger('refresh.owl.carousel');
});

.btn {
    display: inline-block;
    padding: 6px 12px;
    margin-bottom: 0;
    font-size: 14px;
    font-weight: 400;
    line-height: 1.42857143;
    text-align: center;

    user-select: none;
    background-image: none;
    border: 1px solid transparent;
    border-radius: 4px;
}
.btn-success {
    color: #fff;
    background-color: #5cb85c;
    border-color: #4cae4c;
}
