Question

目前我正在使用 Carousel 创建一个组件与指标GetBootstrap Carousel With indicators 我在一个 vue 组件中实现此代码，如：

<template>
    <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
        <ol class="carousel-indicators">
            <div v-for="(image, index) in images" :key="index">
                <li data-target="#carouselExampleIndicators" :data-slide-to="index" :class=" index === 0? 'active' : '' "></li>
            </div>
        </ol>
        <div class="carousel-inner">
            <div v-for="(image, index) in images" :key="index">
                <div :class=" index === 0? 'carousel-item active' : 'carousel-item' ">
                    <img class="d-block w-100" :src="image.path" :alt="image.name">
                </div>
            </div>
        </div>
        <a class="carousel-control-prev" xxx="#carouselExampleIndicators" role="on" data-slide="prev">
            <span class="carousel-control-prev-icon" aria-hidden="true"></span>
            <span class="sr-only">Previous</span>
        </a>
        <a class="carousel-control-next" xxx="#carouselExampleIndicators" role="on" data-slide="next">
            <span class="carousel-control-next-icon" aria-hidden="true"></span>
            <span class="sr-only">Next</span>
        </a>
    </div>
</template>
<script>
    export default {
        props: ["app_route"],
        data() {
            return {
                images: [],
            };
        },
        mounted: function() {
            this.getItemsSlider();
        },
        methods: {
            getItemsSlider() {
                axios
                    .get(this.app_route + "/admin/slider/list", {
                    })
                    .then((response) => {
                        //console.log("response: ", response.data);
                        this.images = response.data;
                    });
            },
        }
    };
</script>

目前第一个图像显示，但其他图像没有显示，滑块也不工作。

为什么？我做错了什么？

根据the documentation，必须严格嵌套元素.carousel-inner > .carousel-item。

你应该试试这个：

<div class="carousel-inner">
  <div v-for="(image, index) in images" :key="index" :class="index === 0 ? 'carousel-item active' : 'carousel-item'">
      <img class="d-block w-100" :src="image" :alt="image.name" />
  </div>
</div>
