图片轮播-vue

做一个中间大两头小的轮播图，使用vue插件 html代码

<template>
  <div class="img-change">
    <ul>
      <li v-for="(item, index) of img" :key="index">
        <img class="pic" :src="require(`../assets/images/img-${item}.png`)" />
      </li>
    </ul>
    <img class="left arrow" @click="replace(false)" src="../assets/images/left.png" alt />
    <img class="right arrow" @click="replace(true)" src="../assets/images/right.png" alt />
  </div>
</template>

js代码

  data() {
    return {
      img: [1, 2, 3, 4, 5],
    };
  },
    created() {
    // 设置定时器；
    setInterval(() => {
      this.replace(true);
    }, 3000);
  },
      replace(right) {
      let temp;
      if (right) {
        temp = this.img[this.img.length - 1];
        for (let i = this.img.length - 1; i > 0; i--) {
          this.$set(this.img, i, this.img[i - 1]);
        }
        this.$set(this.img, 0, temp);
      } else {
        temp = this.img[0];
        for (let i = 0; i < this.img.length - 1; i++) {
          this.$set(this.img, i, this.img[i + 1]);
        }
        this.$set(this.img, this.img.length - 1, temp);
      }
    }
