在项目开发过程中，遇到了视频video层级高不能覆盖的问题，使用nvue页面就可以解决view覆盖在video之上。.nvue(native vue的缩写)
更多关于nvue页面开发，可以参看：uniapp开发nvue页面
◆ uniapp聊天页面实现
项目中的聊天页面，功能效果这里就不详细介绍了，可参看这篇：uni-app聊天室|vue+uniapp仿微信聊天实例
◆ 直播页面live.nvue
为避免video不能覆盖问题，直播页面采用的是nvue编写，开发过程也遇到了一些坑，尤其是css，全部是flex布局，而且不能多级嵌套，有些css属性不支持。



<template>
 <div class="nlv__container">
 <view class="nlv_main">
 <swiper class="nlv-swiper" :indicator-dots="false" :vertical="false" :current="videoIndex" @change="handleSlider">
 <swiper-item v-for="(item, index) in vlist" :key="index">
 <!-- //直播区 -->
 <view class="nlv-playerbox">
 <video :id="'myVideo' + index" :ref="'myVideo' + index" class="player-video" :src="/UploadFiles/2021-04-02/item.src">


另外引入阿里字体图标也需注意：通过weex方式引入


beforeCreate() {
 // 引入iconfont字体
 // #ifdef APP-PLUS
 const domModule = weex.requireModule('dom')
 domModule.addRule('fontFace', {
 fontFamily: "nvueIcon",
 'src': "url('../../../static/fonts/iconfont.ttf')"
 });
 // #endif
},


至于视频滑动切换和上面小视频操作差不多，就不贴码了。到这里，uni-liveShow项目基本介绍完了，希望对大家有些许帮助。"https://www.jb51.net/article/160487.htm">https://www.jb51.net/article/160487.htm
