<!-- 导航条模板 -->
<template>
    <view class="ua__navbar">
        <view class="ua__navbar-wrap" :class="{'custom': custom, 'fixed': fixed || transparent}"
            :style="{'height': customBarH + 'px', 'padding-top': (custom ? statusBarH : 0) + 'px', 'background': bgcolor, 'color': color, 'z-index': zIndex}">

◆ 自定义全端弹窗组件uaPopup

项目中使用到的弹窗均是ua-popup自定义组件实现效果。支持函数式+组件式混合调用。并且支持Nvue原生页面。

<ua-popup v-model="isVisibleConfirm" shadeClose="false" title="标题" xclose z-index="1001"
    content="<div style='color:#ff557f;padding:20px 40px;'>预测未来的最好办法是自己亲手创造未来！</div>"
    :btns="[
        {text: '取消', click: handleCancel},
        {text: '确定', style: 'color:#00aa00;', click: handleOk},
    ]"
/>

<script>
export default {
    methods: {
        handleOk() {
            let $ua = this.$refs.uapopup
            $ua.open({
                content: '人生漫漫，且行且珍惜',
                customStyle: {'background-color': 'rgba(170, 0, 127, 0.6)', 'color': '#fff'},
                time: 3,
                onClose() {
                    $ua.open({
                        type: 'android',
                        content: '<div style="color:#aa007f">不要等待机会，而要创造机会</div>',
                        customStyle: {'width': '210px'},
                        btns: [
                            {
                                text: '关闭',
                                click() {
                                    $ua.close()
                                }
                            },
                            {

                                click() {
                                    // ...
                                }
                            }
                        ]
                    })
                }
            })
        }

◆ uniapp短视频效果

短视频页面分为顶部菜单+视频信息区+底部dock菜单三个模块。视频区使用swiper组件实现上下滑动切换。

<view v-if="currentTab == 2" class="ua__tabcnt-recommend">
    <swiper class="ua__vdplayer-swiper flex1" :current="currentVideo" vertical @change="handleSwipeVertical">
        <swiper-item v-for="(item, index) in videoList" :key="index">
            <!-- 视频模块 -->
            <view class="ua__vdplayer-video flex1">
                <video class="vdplayer" :id="'vdplayer' + index" :ref="'vdplayer' + index"
                    :src="item.src"
                    :controls="false" :loop="true" :show-center-play-btn="false" object-fit="fill"
                    :autoplay="index == currentVideo"
                    @play="isPlaying=true" @timeupdate="handleTimeUpdate"
                    :style="{'width': winWidth, 'height': winHeight}"
                >
                </video>
                <view class="ua__vdplayer-playwrap" @click="handleVideoClicked"><view v-if="!isPlaying" class="ua__vdplayer-playbtn"><text class="iconfont">{{`\ue607`}}</text></view></view>

                    <!-- //左侧信息 -->
                    <view class="vdinfo__left flex1">

    </swiper>
    <!-- 底部播放进度条 -->
    <view class="ua__vdplayer-progress"><view class="bar" :style="{'width': progressBar+'px'}"></view></view>
</view>

顶部导航条及底部tabbar菜单支持全屏沉浸式，并且视频底侧显示Mini播放进度条。

// 播放进度变化时触发
handleTimeUpdate(e) {
    let { currentTime, duration } = e.detail

    this.progressBar = parseInt((currentTime / duration).toFixed(2) * parseInt(this.winWidth))
},

uniapp小视频暂停/播放、上下滑动切换、单击/双击判断等操作。

◆ uniapp直播效果

为了解决video层级高的问题，直播和小视频页面均是全屏沉浸式Nvue语法编码开发。并且项目中的uaNavbar+uaTabbar+uaPopup自定义组件兼容支持Nvue页面。
