<!-- 導航條模板 -->
<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}">

                <template v-else><text :style="{'color': color}">{{title}}</text></template>
            </view>

            <!-- //搜索框 -->
            <view v-if="search" class="action navbar-action__search">
                <slot name="search" />
            </view>

            <!-- //右側 -->

◆ 自定義全端彈窗組件uaPopup

項目中使用到的彈窗均是ua-popup自定義組件實現效果。支持函數式+組件式混合調用。並且支持Nvue原生頁面。

<ua-popup v-model="isVisibleConfirm" shadeClose="false" title="標題" xclose z-index="1001"
    content="<div style='color:#ff557f;padding:20px 40px;'>預測未來的最好辦法是自己親手創造未來！</div>"
    :btns="[
        {text: '取消', click: handleCancel},
        {text: '確定', 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">不要等待機會，而要創造機會</div>',
                        customStyle: {'width': '210px'},
                        btns: [
                            {
                                text: '關閉',
                                click() {
                                    $ua.close()
                                }
                            },
                            {
                                text: '確定',
                                style: 'color:#00aa00;',
                                click() {
                                    // ...
                                }
                            }
                        ]
                    })
                }
            })
        }
    }
}
</script>

支持20+參數自定義配置，多種彈窗動畫及彈窗類型。具體的介紹，可以參看之前的分享文章。

◆ uniapp短視頻效果

 

短視頻頁面分為頂部菜單+視頻信息區+底部dock菜單三個模塊。視頻區使用swiper組件實現上下滑動切換。

<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">
            <!-- 視頻模塊 -->
            <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>

                <view class="flexbox flex-row flex-alignb">
                    <!-- //左側信息 -->
                    <view class="vdinfo__left flex1">
                        <view class="ltitem uavatar flexbox flex-row">
                            <navigator url="#" class="flexbox flex-alignc flex-row"><image class="uimg" :src="item.avatar" /><text class="uname">{{item.author}}</text></navigator>
                            <view class="flexbox btn" :class="{'actived': item.isFollow}" @click="handleFollow(index)"><text class="btn-text">{{item.isFollow ? '已關注' : '關注'}}</text></view>

                        <view v-if="item.topic" class="ltitem flexbox flex-row">
                            <view class="kw" v-for="(kw, index2) in item.topic" :key="index2"><text class="lbl">#{{kw}}</text></view>
                        </view>
                        <view class="ltitem"><text class="desc">{{item.desc}}</text></view>
                    </view>
                    <!-- //右側按鈕 -->
                    <view class="vdinfo__right flexbox flex-col">
                        <view class="rtitem ball" v-if="item.goods&&item.goods.length > 0" @click="handleShowGoodsPopup(item.goods)"><text class="icon iconfont">{{`\ue734`}}</text></view>
                        <view class="rtitem" :class="{'isliked': item.isLike}" @click="handleLiked(index)"><text class="icon iconfont">{{`\ue635`}}</text><text class="num">{{item.likeNum+(item.isLike ? 1 : 0)}}</text></view>
                        <view class="rtitem" @click="showReplyPopup = true"><text class="icon iconfont">{{`\ue632`}}</text><text class="num">{{item.replyNum}}</text></view>
                        <view class="rtitem" @click="showSharePopup = true"><text class="icon iconfont">{{`\ue63b`}}</text><text class="num">{{item.shareNum}}</text></view>
                    </view>
                </view>
            </view>
        </swiper-item>
    </swiper>
    <!-- 底部播放進度條 -->
    <view class="ua__vdplayer-progress"><view class="bar" :style="{'width': progressBar+'px'}"></view></view>
</view>

頂部導航條及底部tabbar菜單支持全屏沉浸式，並且視頻底側顯示Mini播放進度條。

// 播放進度變化時觸發
handleTimeUpdate(e) {
    let { currentTime, duration } = e.detail
    
    this.progressBar = parseInt((currentTime / duration).toFixed(2) * parseInt(this.winWidth))
},

uniapp小視頻暫停/播放、上下滑動切換、單擊/雙擊判斷等操作。

◆ uniapp直播效果

為了解決video層級高的問題，直播和小視頻頁面均是全屏沉浸式Nvue語法編碼開發。並且項目中的uaNavbar+uaTabbar+uaPopup自定義組件兼容支持Nvue頁面。
