vue3实现图片拉霸机代码

以下是一个简单的 Vue3 图片拉霸机示例代码：

<template>
  <div class="slotmachine">
    <div class="slotmachine-container">
      <div class="slotmachine-image" v-for="(image, index) in images" :key="index" :style="{ transform: 'translateY(' + (imagePosition - index * imageHeight) + 'px)' }">
        <img :src="image" />
      </div>
    </div>
    <div class="slotmachine-controls">
      <button @click="start">Start</button>
      <button @click="stop">Stop</button>
    </div>
  </div>
</template>

<script>
import { reactive, ref } from 'vue';

export default {
  setup() {
    const images = reactive([
      'image1.jpg',
      'image2.jpg',
      'image3.jpg',
      'image4.jpg',
      'image5.jpg',
    ]);
    const imageHeight = 100;
    const imagePosition = ref(0);
    let intervalId = null;

    const start = () => {
      clearInterval(intervalId);
      intervalId = setInterval(() => {
        imagePosition.value += imageHeight;
      }, 100);
    };

    const stop = () => {
      clearInterval(intervalId);
      const position = Math.round(imagePosition.value / imageHeight) * imageHeight;
      imagePosition.value = position;
    };

    return {
      images,
      imageHeight,
      imagePosition,
      start,
      stop,
    };
  },
};
</script>

<style>
.slotmachine {
  display: flex;
  flex-direction: column;
  align-items: center;
}

.slotmachine-container {
  width: 100px;
  height: 300px;
  overflow: hidden;
}

.slotmachine-image {
  width: 100%;
  height: 100px;
  display: flex;
  justify-content: center;
  align-items: center;
}

.slotmachine-image img {
  width: 80%;
  height: 80%;
  object-fit: contain;
}

.slotmachine-controls {
  margin-top: 20px;
}

.slotmachine-controls button {
  margin-right: 10px;
}
</style>

这个示例代码中，我们使用了 Vue3 中的 `reactive` 和 `ref` 方法来定义响应式数据，使用了 `setup` 函数来编写逻辑代码，并在模板中使用了动态绑定和计算属性来实现图片的滚动和停止。同时，我们使用了 CSS 来设置图片和容器的样式，以便它们在组件中正确地显示。
