javascript - 为什么我的 Swiper 滑块在 Django 中不起作用？

问题描述

到目前为止，设置 Swiper 轻而易举。所有图像都完美地加载到容器中，并且控制台不会记录任何错误。

但是，虽然导航按钮出现并且是可点击的，但它们实际上并不起作用。单击和拖动它们也不会。控制台显示所有图像都已加载。

其他人也有类似的问题，并且有效的修复是添加：

observer: true,
observeParents: true,

对于初始化代码，这对我没有任何影响。

这是我的 HTML 代码

<head>
    <link rel="stylesheet" href="https://unpkg.com/swiper/css/swiper.min.css">
</head>
<div class="swiper-container gallery-top">
            <div class="swiper-wrapper">
                {% for image in car.image_set.all %}
                    <div class="swiper-slide"><img src="{{ image.image.url }}" style="width: 100%; "></div>
                {% endfor %}
                <div class="swiper-button-prev"></div>
                <div class="swiper-button-next"></div>
            </div>    
        </div>
    </div>

...

<script src="https://unpkg.com/swiper/js/swiper.min.js"></script>
...
<script>
    var galleryTop = new Swiper('.gallery-top', {
        spaceBetween: 10,
        loop:true,
        loopedSlides: 5, //looped slides should be the same
        navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev',
        },
        observer: true, 
        observeParents: true,
        observeSlideChildren: true,
    });
</script>

更新

感谢 Pratik 的反馈，我更新了 js，但 Swiper 仍然没有导航图像。没有控制台错误，它似乎已经死了。

解决方案

Observer和ObserveParents不是导航的一部分。所以用下面的代码更新你的脚本。

<script> var galleryTop = new Swiper('.gallery-top', { spaceBetween: 10, loop:true, loopedSlides: 5, //looped slides should be the same navigation: { nextEl: '.swiper-button-next', prevEl: '.swiper-button-prev', }, observer: true, observeParents: true, observeSlideChildren: true }); </script>

** 这是呈现的 HTML **

<head>
    <link rel="stylesheet" href="https://unpkg.com/swiper/css/swiper.min.css">
</head>

...
<body>
    <div class="container">
        <div class="swiper-container gallery-top">
            <div class="swiper-wrapper">

                    <div class="swiper-slide"><img src="/media/image_11.JPG" style="width: 100%; "></div>

                    <div class="swiper-slide"><img src="/media/image_12_YQm2sd3.JPG" style="width: 100%; "></div>

                    <div class="swiper-slide"><img src="/media/image_19.JPG" style="width: 100%; "></div>

                    <div class="swiper-slide"><img src="/media/image_16_pm7OKF2.JPG" style="width: 100%; "></div>

            </div>    
            <div class="swiper-button-prev"></div>
            <div class="swiper-button-next"></div>
        </div>
    </div>
