初始设置的代码：
WXML的代码
<view class="card-wrapper"> <!-- 视频播放容器（默认隐藏） --> <view class="video-container" wx:if="{{isPlaying}}"> <video id="cardVideo" class="card-video" src="{{item.videoUrl}}" autoplay controls bindplay="onVideoPlay" bindpause="onVideoPause" bindended="onVideoEnd" ></video> <view class="video-close-btn" bindtap="togglePlay"> <image src="https://images.biliq.com/images/miniprogram/paopao2.0/paopaoCard/close.png" mode="aspectFit" /> </view> </view> <!-- 封面图容器（播放时隐藏） --> <view class="banner-mask" wx:if="{{!isPlaying}}"> <image class="banner-img" src="{{item.cover}}" mode="aspectFill" /> <!-- 播放按钮 --> <view class="play-mask" bindtap="togglePlay"> <image class="play-icon" src="https://images.biliq.com/images/miniprogram/paopao2.0/paopaoCard/play.png" mode="aspectFit" /> </view> <!-- 点赞、转发、导航 --> <view class="action-bar-wrapper"> <actionBar class="action-bar" item="{{item}}" bind:action="onAction" /> </view> </view> <!-- 名称区域 --> <view class="desc-mask" wx:if="{{!isPlaying}}"> <!-- 名称 --> <text class="banner-title">{{item.title}}</text> <!-- 挂载件 --> <actionMount wx:if="{{item.ismount}}" class="has-mount" item="{{item}}" bind:action="onAction" /> <!-- 无挂载 --> <view wx:elif="{{!item.ismount}}" class="no-mount" item="{{item}}" bind:action="onAction" /> <!-- 详情 --> <view wx:if="{{!item.ismount}}" class="more-mask" bindtap="handleDatail"> <image class="more-img" src="https://images.biliq.com/images/miniprogram/paopao2.0/paopaoCard/more.png" /> </view> </view> <!-- 标签区域 --> <view class="tag-list" wx:if="{{!isPlaying}}"> <block wx:for="{{item.tags}}" wx:key="index" wx:if="{{index < 3}}"> <view class="tag-mask {{item.spotag ?

JS的代码
Component({ properties: { item: Object }, data: { isPlaying: false, videoContext: null }, methods: { // 切换播放状态 togglePlay() { if (this.data.isPlaying) { // 如果正在播放，则暂停并隐藏视频 this.data.videoContext.pause(); this.setData({ isPlaying: false }); } else { // 如果未播放，则显示视频并播放 this.setData({ isPlaying: true }, () => { this.data.videoContext = wx.createVideoContext('cardVideo', this); this.data.videoContext.play(); }); } }, // 视频开始播放 onVideoPlay() { console.log('视频开始播放'); }, // 视频暂停 onVideoPause() { console.log('视频已暂停'); }, // 视频播放结束 onVideoEnd() { this.setData({ isPlaying: false }); }, // 其他原有方法... onAction(e) { // 原有逻辑 }, handleDatail() { // 原有逻辑 } }, // 组件卸载时销毁视频实例 detached() { if (this.data.videoContext) { this.data.videoContext.pause(); } } });
WXSS的代码
.card-wrapper { position: relative; width: 100%; border-radius: 12rpx; overflow: hidden; } /* 视频容器样式 */ .video-container { position: relative; width: 100%; height: 0; padding-bottom: 56.25%; /* 16:9 比例 */ } .card-video { position: absolute; top: 0; left: 0; width: 100%; height: 100%; } .video-close-btn { position: absolute; top: 20rpx; right: 20rpx; width: 60rpx; height: 60rpx; z-index: 10; } .video-close-btn image { width: 100%; height: 100%; } /* 原有样式保持不变 */ .banner-mask { position: relative; width: 100%; height: 0; padding-bottom: 56.25%; /* 16:9 比例 */ } .banner-img { position: absolute; top: 0; left: 0; width: 100%; height: 100%; } .play-mask { position: absolute; top: 0; left: 0; width: 100%; height: 100%; display: flex; justify-content: center; align-items: center; background-color: rgba(0, 0, 0, 0.3); } .play-icon { width: 100rpx; height: 100rpx; } /* 其他原有样式... */
上述代码展示效果如下
上述代码可以实现视频播放，但是样式不是很好看，我们可以增加一些设置，比如视频和父视图的卡片一样，视频居中展示播放等等，下面是优化后的代码。
