Chương 4-Bài 5. Tạo component Slider cho trang web NetaShop

Step 1: tạo component Slider

• Tạo file project-netashop/src/components/Slider.vue
• Nội dung file như sau:

<template>
  <div :id="id" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
      <li :data-target="'#' + id"
        v-for="(slide, index) in this.sliders" :key="slide.id"
        :class="{ 'active': index === 0 }"
        :data-slide-to="index">
      </li>
    </ol>
    <div class="carousel-inner">
      <div class="carousel-item"
          v-for="(slide, index) in this.sliders" :key="slide.id"
          :class="{ 'active': index === 0 }">
        <img :src="slide.url" class="d-block w-100 slider-img" :alt="slide.alt" />
        <div class="carousel-caption d-none d-md-block">
          <h3>{{ slide.caption }}</h3>
          <p>{{ slide.description }}</p>
        </div>
      </div>
    </div>
    <a
      class="carousel-control-prev"
      :href="'#' + id"
      role="button"
      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"
      :href="'#' + id"
      role="button"
      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: {
    id: {
      type: String,
      required: true
    },
    sliders: {
      type: Array,
      required: true,
      default () {
        return [
          { id: 1, url: require('@/assets/img/slider/slider-1.jpg'), alt: 'Alt slider 1', caption: 'Slider 1', description: 'Descriptio slider 1' },
          { id: 2, url: require('@/assets/img/slider/slider-2.jpg'), alt: 'Alt slider 2', caption: 'Slider 2', description: 'Descriptio slider 2' },
          { id: 3, url: require('@/assets/img/slider/slider-3.jpg'), alt: 'Alt slider 3', caption: 'Slider 3', description: 'Descriptio slider 3' }
        ]
      }
    }
  },
  data () {
    return {
    }
  }
}
</script>

<style scoped>
.slider-img {
  height: 250px;
  object-fit: cover;
}

.carousel-caption {
  bottom: 3rem;
  z-index: 10;
  color: white;
  text-shadow: 2px 2px 5px black;
}
</style>

Step 2: import Slider và sử dụng Slider cho Trang chủ Home

• Hiệu chỉnh file project-netashop/src/pages/Home.vue
• Nội dung file như sau:

<template>
  <div id="home-page">
    <section>
      <div class="row">
        <div class="col">
          <slider id="home-page-slider" v-bind:sliders="this.homeSliders" />
        </div>
      </div>
    </section>
  </div>
</template>

<script>
import Slider from '@/components/Slider'

export default {
  components: {
    Slider
  },
  data () {
    return {
      homeSliders: [
        {
          id: 1,
          url: require('@/assets/img/slider/slider-1.jpg'),
          alt: 'Nền tảng - Nơi mua sắm tuyệt vời',
          caption: 'Nền tảng - Nơi mua sắm tuyệt vời',
          description: 'Địa điểm tin cậy, chất lượng và uy tín'
        },
        {
          id: 2,
          url: require('@/assets/img/slider/slider-2.jpg'),
          alt: 'Hàng triệu sản phẩm - Lựa chọn mỏi tay',
          caption: 'Hàng triệu sản phẩm - Lựa chọn mỏi tay',
          description: 'Hàng hóa đa dạng, lựa chọn thoải mái'
        }
      ]
    }
  }
}
</script>

<style>

</style>
