给我一个轮播图代码vue

以下是一个简单的Vue轮播图代码示例：

<template>
  <div class="carousel">
    <div class="slide" v-for="(image, index) in images" :key="index" v-show="index === currentSlide">
      <img :src="image" alt="Slide">
    </div>
    <div class="controls">
      <button @click="previousSlide">Previous</button>
      <button @click="nextSlide">Next</button>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      currentSlide: 0,
      images: [
        "https://via.placeholder.com/800x300?text=Slide+1",
        "https://via.placeholder.com/800x300?text=Slide+2",
        "https://via.placeholder.com/800x300?text=Slide+3"
      ]
    };
  },
  methods: {
    nextSlide() {
      this.currentSlide = (this.currentSlide + 1) % this.images.length;
    },
    previousSlide() {
      this.currentSlide =
        (this.currentSlide - 1 + this.images.length) % this.images.length;
    }
  }
};
</script>

<style>
.carousel {
  position: relative;
  width: 800px;
  height: 300px;
  overflow: hidden;
}
.slide {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
}
.slide img {
  max-width: 100%;
  max-height: 100%;
}
.controls {
  position: absolute;
  bottom: 10px;
  left: 50%;
  transform: translateX(-50%);
  display: flex;
  justify-content: center;
  align-items: center;
}
.controls button {
  margin: 0 10px;
  padding: 10px;
  border: none;
  background-color: #ccc;
  cursor: pointer;
}
</style>

以上代码实现了一个基本的轮播图，图片数组存储了三张图片的链接，使用了Vue的`v-for`指令渲染出每一张图片的`<img>`标签，使用了`v-show`指令根据当前的`currentSlide`变量来决定哪一张图片显示。两个按钮用于切换上一张和下一张图片，点击按钮时更新`currentSlide`变量即可。最后，通过CSS实现了轮播图容器和图片的样式，以及按钮的样式。
