Vue と Canvas を使用してエレガントな画像カルーセル コンポーネントを作成する方法

<div id="app">
  <canvas ref="canvas"></canvas>
</div>

Vue.component('image-slider', {
  template: '<canvas ref="canvas"></canvas>',
  mounted() {
    this.canvas = this.$refs.canvas;
    this.context = this.canvas.getContext('2d');
    this.setup();
  },
  methods: {
    setup() {
      // 设置Canvas尺寸
      this.canvas.width = window.innerWidth;
      this.canvas.height = window.innerHeight;

      // 加载图片
      this.images = [
        'image1.jpg',
        'image2.jpg',
        'image3.jpg'
      ];
      this.loadedImages = [];
      this.loadImages();
    },
    loadImages() {
      let loadedCounter = 0;
      this.images.forEach((src, index) => {
        const img = new Image();
        img.src = src;
        img.onload = () => {
          loadedCounter++;
          this.loadedImages[index] = img;
          if (loadedCounter === this.images.length) {
            this.start();
          }
        };
      });
    },
    start() {
      // 开始轮播
      setInterval(() => {
        this.context.clearRect(0, 0, this.canvas.width, this.canvas.height);
        this.currentImageIndex++;
        if (this.currentImageIndex === this.loadedImages.length) {
          this.currentImageIndex = 0;
        }
        this.context.drawImage(this.loadedImages[this.currentImageIndex], 0, 0, this.canvas.width, this.canvas.height);
      }, 3000);
    }
  },
  data() {
    return {
      canvas: null,
      context: null,
      images: [],
      loadedImages: [],
      currentImageIndex: 0
    };
  }
});

new Vue({
  el: '#app'
