回顾上一次咱们胜利应用 HbuilderX + uni-app + 智密原生仿抖音高低滑动插件创立了属于本人的第一个短视频 App,在这里我给他取名瓜皮视频,而后我又应用了官网的 demo 进行了一波革新,接下来看看咱们的瓜皮视频与抖音的比照图呗:
理论还是有一些轻微的区别的,然而呢类似度和晦涩度曾经算得上是不错的了。实现了根底的性能,咱们未免要看看还有啥性能能够附带上。这里咱们看了下,短视频 App 未免在视频页减少了“小红包”和“购物车”的性能,这是俩个流量收割利器,这里咱们接着上回的我的项目,持续来扩大性能。
小红包 界面剖析
智密原生仿抖音高低滑动插件应用的是给 asv_list_player 组件传入控件配置的形式去管制原生控件的展现,所以界面上很简略只有这写代码
<template>
<view>
<asv_list_player ref="listPlayer" class="player"></asv_list_player>
<bottom-popover v-if="showBottomPopover" ref="popover" @close="onClosePopover">
<t-pop-commit-list></t-pop-commit-list>
</bottom-popover>
</view>
</template>
实现小红包
在这里咱们实现“小红包”的性能诚然也能够应用传入控件配置的形式,然而思考到还有红包进度条以及管制显隐,这里咱们能够用 nvue 布局,本人实现一个红包控件,上代码
<template>
<view>
<asv_list_player ref="listPlayer" class="player"></asv_list_player>
<!-- 这上面就是咱们新增的红包控件,为了不便咱们应用了简略的组件,圈圈 + 红包 -->
<view class="float-red-paper">
<image class="float-red-paper-elem" mode="widthFix" src="../../static/icon_redPaper.png"></image>
</view>
<bottom-popover v-if="showBottomPopover" ref="popover" @close="onClosePopover">
<t-pop-commit-list></t-pop-commit-list>
</bottom-popover>
</view>
</template>
.float-red-paper {
position: fixed;
top: 80px;
left: 15px;
width: 60px;
height: 60px;
align-items: center;
justify-content: center;
background-color: rgba(0, 0, 0, 0.6);
border-radius: 100%;
}
.float-red-paper-elem {width: 40px;}
在这里须要留神几点,首先 nvue 的控件是从上到下顺次从前到后的层级排序的,并且无奈通过 zindex 调整元素层级,因而咱们插入“小红包”要在 asv_list_player 之后。css 的话不反对层级语法,因而这里咱们还是采纳 BEM 命名的形式来写款式。当初咱们看看加上“小红包”的成果,尽管这里咱们还没增加完点击事件啥的,前面再来补充嘛。
购物车 界面剖析
实现实现了小红包,接下来咱们要实现购物车的性能,因为这里购物车是可能每个视频都会有的,并且每个视频关联的数据可能不一样,因而咱们间接通过插件自带的配置 JSON 来解决。
在这里咱们构思的是将购物车设置在昵称简介上面,也就是绿色的区域,而后将昵称信息向上调整,也就是蓝色区域。
实现购物车
首先咱们革新之前得先看一下原先的配置。
asvListPlayer.getView('titleBox').isLayer().position(['left', 'bottom']).width(screenWidth * 0.6).height(100).bgc('#55000000').marginLeft(15).marginBottom(15).radius(10)
.children([asvListPlayer.getView('userBox').isLayer().position(['left']).width('100%').height('auto').marginLeft(10).marginTop(10)
.children([asvListPlayer.getView('userIcon').isImage().position('left').width(15).height(15).marginTop(3).radius(10).toJSON(),
asvListPlayer.getView('userName').isText().position('left').width('100%').height(20).lines(2).color('#ffffff').marginLeft(20).toJSON(),])
.toJSON(),
asvListPlayer.getView('title').isText().position('left').width('100%').height('auto').color('#ffffff').marginLeft(10).marginTop(35).marginBottom(10).fontSize(14).marginRight(10).toJSON(),])
.toJSON(),
在原先的配置中,昵称信息这里是间隔底部 15px,也就是如下代码
asvListPlayer.getView('titleBox').isLayer().position(['left', 'bottom']).width(screenWidth * 0.6).height(100).bgc('#55000000').marginLeft(15).marginBottom(15)
而咱们须要给购物车留出大略 40 像素的中央,再加上高低距离之后,咱们把这块的 15px 调整成为 75px 就能够完满留进去购物车的中央,如下所示。
asvListPlayer.getView('titleBox').isLayer().position(['left', 'bottom']).width(screenWidth * 0.6).height(100).bgc('#55000000').marginLeft(15).marginBottom(75)
而后我这里间接给出购物车局部相干的代码,首先是 json 配置局部:
asvListPlayer.getView('goodCar').isLayer().position(['left', 'bottom']).width(110).height(40).bgc('#55000000').marginLeft(15).marginBottom(15).radius(30)
.children([asvListPlayer.getView('goodCarImage').isImage().position(['left']).width(30).height(30).marginTop(5).marginLeft(5).toJSON(),
asvListPlayer.getView('goodCarText').isText().position(['left']).width(80).height(30).marginLeft(45).marginTop(5).lines(1).fontSize(16).color('#ffffff')
])
.toJSON()
这里咱们设计大略是 110px 的宽度,而后购物车标记是 30px,留进去 80px 左右的地位提供给视频,这里就先写上购物车三个字,而后这里我在给绑定数据局部的代码。
this.genData().forEach(item => {let data = asvListPlayer.getItem(item.i)
.video(item.v)
.cover(item.c)
.bindImage('head', 'https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=3533321036,2623280788&fm=15&gp=0.jpg', true)
.bindImage('like', item.like ? 'https://files.qiadoo.com/CareBoBo/Common/2021/05/17/c94c1a75-094a-482a-9acf-f1eefbd24792.png':'https://files.qiadoo.com/CareBoBo/Common/2021/05/17/5a17a78c-f923-41f3-8916-271b4d5d528f.png')
.bindText('likeText', parseInt((item.i * 1 + 1) * (new Date().getTime()) / 1000000000000) + '.4w')
.bindImage('commit', 'https://files.qiadoo.com/CareBoBo/Common/2021/05/17/003910f2-92cf-40c5-9d8a-870401be6e41.png')
.bindText('commitText', parseInt((item.i * 1 + 1) * (new Date().getTime()) / 10000000000) + '')
.bindImage('share', 'https://files.qiadoo.com/CareBoBo/Common/2021/05/17/353edf1a-c2f1-481a-87fc-b9d5df98fb9e.png')
.bindText('shareText', '分享')
.bindText('userName', `UserName`)
.bindImage('userIcon', 'https://files.qiadoo.com/CareBoBo/Common/2021/05/17/89898f94-c3b8-4e14-9d06-7ccb1f27d3ab.png')
.bindText('title', ` 这是第 ${item.i * 1}个视频,轻轻是离别的笙箫,缄默是今晚的康桥,再别康桥,再见我终将逝去的青春,愿所有安好,愿你永远都在。`)
.bindImage('goodCarImage', 'https://files.qiadoo.com/CareBoBo/Common/2021/06/20/35177433-c373-49c7-8c21-f7db6c9d5c8f.png')
.bindText('goodCarText', '购物车')
.toJSON()
datas.push(data)
})
这里新增的要害就是最初俩个,也就是上面俩个:
.bindImage('goodCarImage', 'https://files.qiadoo.com/CareBoBo/Common/2021/06/20/35177433-c373-49c7-8c21-f7db6c9d5c8f.png')
.bindText('goodCarText', '购物车')
不得不说,插件自身曾经帮咱们做好大量配置的工作了,这里我只须要 bindImage 和 bindText 就能够将购物车标记的图片和文字绑定实现啦。尽管这里咱们还没有绑定事件,然而长城也不是一日建成的,一步步扩大性能呗。先看看效果图。
尽管不能说很完满,然而曾经开始有那滋味了,当初我把革新一半的代码间接给大家,有意思的能够持续接着扩大咱们的瓜皮视频哦。
