1.Vue 组件的模板部分
视频容器 ：使用一个 div 元素作为视频的容器，具有样式 video-container。
html
<div class="video-container">
<video :src="currentVideoSrc" autoplay muted loop :class="{ active: isActive }"></video>
</div>:src="currentVideoSrc"：使用 Vue 的数据绑定将视频的src属性设置为currentVideoSrc，这个属性会动态地指向当前播放的视频路径。autoplay：视频加载后自动播放。muted：视频静音播放。loop：视频循环播放。:class="{ active: isActive }"：根据isActive的值动态添加或移除active类，以控制视频的显示和隐藏。
2.JavaScript 部分
数据属性定义：
videos：一个包含视频路径的数组。currentIndex：用于跟踪当前播放的视频索引。
javascript
data() {
return {
videos: [
require('@/assets/videos/video.mp4'),
// 添加更多视频路径
],
currentIndex: 0,
// 其他数据属性...
};
},计算属性：
currentVideoSrc：动态获取当前播放的视频路径。isActive：用于控制视频是否处于激活状态。
javascript
computed: {
currentVideoSrc() {
return this.videos[this.currentIndex];
},
isActive() {
return this.currentIndex === 0; // 或者根据需求设置其他条件
}
},播放视频的方法：
playNextVideo：定时更改currentIndex来循环播放视频。
javascript
methods: {
playNextVideo() {
setInterval(() => {
this.currentIndex = (this.currentIndex + 1) % this.videos.length;
}, 5000); // 每 5 秒切换一次视频
},
// 其他方法...
},生命周期钩子：
- 在
mounted钩子中调用playNextVideo方法。确保组件挂载后视频自动播放。
javascript
mounted() {
this.playNextVideo();
},3.样式
css
.video-container {
position: relative;
width: 100vw;
height: 100vh;
overflow: hidden;
}
.video-container video {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
object-fit: cover;
opacity: 0;
transition: opacity 1s ease-in-out;
}
.video-container video.active {
opacity: 1;
