Buefy Carousel Thumbnail Indicator 显示重复图像(Vuejs)

Buefy Carousel Thumbnail Indicator show duplicated image (Vuejs)

我正在尝试创建带有垂直缩略图的轮播,但缩略图被复制了。我只有 2 个图片网址,但它显示了 4 个缩略图。

App.vue:

<template>
  <div id="app">
    <b-carousel
      :indicator-inside="false"
      class="is-hidden-mobile"
      :pause-hover="false"
      :pause-info="false"
    >
      <b-carousel-item v-for="(item, i) in imagess" :key="i">
        <figure class="image">
          <img :src="item.url">
        </figure>
      </b-carousel-item>
      <span v-if="gallery" @click="switchGallery(false)" class="modal-close is-large"/>
      <template slot="indicators" slot-scope="props">
        <span class="al image">
          <img v-for="(p,index) in imagess" :key="index" :src="p.url" :title="props.i">
        </span>
      </template>
    </b-carousel>
  </div>
</template>

<script>
export default {
  name: "App",
  components: {},
  data() {
    return {
      bundledatas: null,
      imagess: [
        {
          url:
            "https://specials-images.forbesimg.com/imageserve/37645633/960x0.jpg?cropX1=445&cropX2=3910&cropY1=258&cropY2=2207"
        },
        {
          url:
            "https://www.sovereigngroup.com/wp-content/uploads/2018/12/HK-4.jpg"
        }
      ]
    };
  }
};
</script>

<style>
#app {
  font-family: "Avenir", Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
.is-active .al img {
  filter: grayscale(0%);
}
.al img {
  filter: grayscale(100%);
  margin: 2px 0;
}

.carousel {
  display: grid;
  grid-template-columns: auto 25%;
  align-items: center;
}

.carousel-indicator {
  flex-direction: column;
}

.indicator-item {
  margin-right: initial !important;
}
</style>

demo

我只想显示 2 个缩略图(每个图像一个),如下所示:

问题是您的 indicators 插槽显示了 imagess 所有 项,而它应该只显示 props.i 中指定的项, 这是轮播中显示的当前索引。

解决方案是通过 props.i 中的索引查找 imagess 中的项目,并相应地设置 img 的来源 URL:

<template slot="indicators" slot-scope="props">
  <span class="al image">
    <!-- BEFORE: -->
    <!-- <img v-for="(p,index) in imagess" :key="index" :src="p.url" :title="props.i"> -->

    <img :src="imagess[props.i].url">
  </span>
</template>
