最近需要写一个评论区功能,所以打算仿照抖音做一个评论功能,支持展开和收起,
首先我们需要对功能做一个拆解,评论区功能,两个模块,一个是发表评论模块,一个是评论展示区。接下来对这两个模块进行详细描述。
使用到的技术 uniapp uview2.0 文章最后我会贴上全部源码
一、发表评论模块
这个模块使用uview的两个组件来完成分别是u-popup弹出层和u-input输入框
下面是代码和展示图:
<u-popup :show="talkShow" mode="bottom" :customStyle="{'width':'100%','border-radius':'8rpx'}" @close="popclosed" @open="keyboard=true" :safeAreaInsetBottom="true">
<view class="flex justify-between align-center" style="padding: 32rpx;">
<div class="cirbOX padding-left padding-right-sm">
<u--form labelPosition="left" :model="talkData" :rules="Rules" ref="Form" :borderBottom="false">
<u-form-item label=" " prop="txt" :borderBottom="false" ref="item1" labelWidth='0'>
<u--input :focus="keyboard" v-model="talkData.txt" cursorSpacing="30" maxlength="100" :placeholder="pinglunHolder" border="none" clearable></u--input>
</u-form-item>
</u--form>
</div>
<div class="submitpinglun" @click="submit">发布</div>
</view>
</u-popup>
这部分需要注意两点
1.input组件的focus属性的设置:
在弹出层弹出的时候 在open事件中对input的focus属性布尔值设置为true,close时候设置focus为false。这样做的目的是在弹出输入评论的弹窗时会拉起小键盘,这个交互方式是模仿的微信朋友圈发布评论的形式。
2.input的cursorSpacing属性(输入框聚焦时底部与键盘的距离)设置:
当键盘拉起时候整个输入框因为设置了cursorSpacing="30",故整体页面会被小键盘托起。 当收起小键盘时候,输入框有回归到手机底部,因为我们popup设置的是底部的弹出层。这样是和微信朋友圈发布评论是对标的。
二、展示评论区的功能
这一部分我封装成了组件,因为需求的要求需要下拉加载评论故在组件外部循环一级评论,组件内部展示一级评论和二级评论,其中二级评论是在组件内部去循环,
循环一级评论的时候需要注意,因为后续要获取pinglun组件的实例,所以在ref的设置上面起初我按照for循环提供的index来拼的字符串,这也导致后续bug的出现埋下伏笔,所以我后续调整了,选择了id这个唯一值作为组件实例的ref名字,这个很关键!
<div v-for="(item,index) in onePagePinglunList" :key="item.id" class="margin-bottom">
<pinglun :ref="`pinglun-${item.levelOneCommentVo.id}`" :caseIdData="caseId" :data="item" :indexxx="index" @comment="goComment" @noLogin="sonNoLogin"></pinglun>
</div>
组件代码:
<template>

<u-icon name="arrow-up" color="#00875A" size="28rpx" :bold="true"></u-icon>
</div>
</div>
</div>
</template>
感觉唯一的难点在于因为展开收缩使用的过渡动画,大家应该都知道,想使用这个过渡必须设置有效值,也就是说比如我给高度写过渡动画,从一个高度到一个高度,都需要是具体的值,atuo这种被内容撑开的高度是不作数的。
这里拿高度,需要注意的是需要等待渲染完毕再去获取高度,不然拿到的值就是不准确的。
下面是我写的获取高度的函数。如果一个nexttick也获取不到准确高度,那么就再加个延时器,就差不多可以获取到准确高度了。
updatHeight() {
let that = this
this.$nextTick(() => {
// this.timer = setTimeout(() => {
this.createSelectorQuery().select(".pinglunDom").boundingClientRect(function(rect) {
// console.log(rect);
that.pingjiaBoxMaxHeight = rect.height
that.pinglunOpcity = 1
}).exec();
// }, 0)
})
},
还有一个需要注意的点,就是在一级评论发布之后,需要拿到所有pinglu组件的实例去调用这个方法,重置所有二级评论的高度。调用这个方法的前提也必须是一级评论的渲染完毕,不然还是不起作用
以下是代码:
this.$forceUpdate();
this.$nextTick(() => {
for (let i = 0; i < this.onePagePinglunList.length; i++) {
this.$refs[`pinglun-${this.onePagePinglunList[i].levelOneCommentVo.id}`][0].updatHeight()
if (this.onePagePinglunList[i].twoLevelpinglun.length === 0) {
this.$refs[`pinglun-${this.onePagePinglunList[i].levelOneCommentVo.id}`][0].params.current = 1
}
}
})
至此应该就没什么需要注意的地方了
可能也是第一次写这个功能,还有很多可以优化的地方。希望对各位有所帮助,接下来我把评论功能所有源码贴在下面。
因为我的评论功能是在案例详情里面的,所以有两个文件,一个是案例详情,一个就是封装的评论组件
