vue.js - 如何在Vue(Quasar)中以简单的方式删除轮播中的箭头

Question

这是我需要的条件:

如果只有一张图片，两边不要显示箭头即可；如果有多个，则显示它。

或者您可以在 https://quasar.dev/vue-components/carousel 中找到它

<template>
    <div class="q-pa-md">
        <q-carousel
           swipeable
           animated
      arrows
      v-model="slide"
      v-model:fullscreen="fullscreen"
      infinite
    >
      <q-carousel-slide :name="1" img-src="https://cdn.quasar.dev/img/mountains.jpg" />
      <q-carousel-slide :name="2" img-src="https://cdn.quasar.dev/img/parallax1.jpg" />
      <q-carousel-slide :name="3" img-src="https://cdn.quasar.dev/img/parallax2.jpg" />
      <q-carousel-slide :name="4" img-src="https://cdn.quasar.dev/img/quasar.jpg" />

      <template v-slot:control>
        <q-carousel-control
          position="bottom-right"
          :offset="[18, 18]"
        >
          <q-btn
            push round dense color="white" text-color="primary"
            :icon="fullscreen ? 'fullscreen_exit' : 'fullscreen'"
            @click="fullscreen = !fullscreen"
          />
        </q-carousel-control>
      </template>
    </q-carousel>
  </div>
</template>

<script>
import { ref } from 'vue'

export default {
  setup () {
    return {
      slide: ref(1),
      fullscreen: ref(false)
    }
  }
}
</script>

Make an array of images and write this:

:arrows="photos.length > 1"
