预览

var swiper = new Swiper(".mySwiper", {
    // 同时显示数量
    slidesPerView: 3,
    // 是否居中，true表示居中，false表示居左
    centeredSlides: false,

视差效果

  • data-swiper-parallax属性控制元素位移，单位为px何百分比。
  • data-swiper-parallax-opacity属性控制元素透明度，必须设置位移。
  • data-swiper-parallax-scale属性控制元素缩放，必须设置位移。
  • data-swiper-parallax-duration属性控制视差动画时长。

延迟加载

  • 图片延迟加载：需要将图片img标签的src改写成data-src，并且增加类名swiper-lazy。
  • 背景图延迟加载：载体增加属性data-background，并且增加类名swiper-lazy。
<div class="swiper">
    <div class="swiper-wrapper">
        <!-- 延迟加载图片的结构 -->
        <div class="swiper-slide">
            <!-- 延迟加载图片 -->
            <img data-src="path/to/picture-1.jpg" class="swiper-lazy">
            <!-- 加载进度条 -->
            <div class="swiper-lazy-preloader swiper-lazy-preloader-white"></div>
        </div>

        <!-- 延迟加载背景图的结构 -->
        <div class="swiper-slide">
             <!-- 延迟加载背景图片 -->
            <div data-background="path/to/picture-2.jpg" class="swiper-lazy">
                <div class="swiper-lazy-preloader"></div>
            </div>
        </div>
    </div>
</div>

var swiper = new Swiper(".mySwiper", {
    // 开启延迟加载
    lazy: true,
    pagination: {
        el: ".swiper-pagination",
        clickable: true,
    },
    navigation: {
        nextEl: ".swiper-button-next",
        prevEl: ".swiper-button-prev",
    },
});

自适应高度

自动高度。设置为 true 时，wrapper 和container 会随着当前slide 的高度而发生变化。

var swiper = new Swiper('.swiper', {
    autoHeight: true, //高度随内容变化
});

放大缩小

<div class="swiper mySwiper">
    <div class="swiper-wrapper">
        <div class="swiper-slide">
            <div class="swiper-zoom-container">
                <img src="./images/nature-1.jpg" />
            </div>
        </div>
        <div class="swiper-slide">
            <div class="swiper-zoom-container">
                <img src="./images/nature-2.jpg" />
            </div>
        </div>
        <div class="swiper-slide">
            <div class="swiper-zoom-container">
                <img src="./images/nature-3.jpg" />
            </div>
        </div>
    </div>
</div>

var swiper = new Swiper(".mySwiper", {
    // 开启缩放
    zoom: true
});
