uni-app实现点赞评论功能

模拟朋友圈实时点赞及评论功能点赞思路：点击的时候，使用push（点赞）以及slice（取消赞

模拟朋友圈实时点赞及评论功能

点赞思路：点击的时候，使用push（点赞）以及slice（取消赞）方法处理数组，并且调用点赞接口

评论思路：点击的时候，写多一个评论列表，当点击发送的时候commentStatus=true，且索引等于点击的索引。同时调用获取评论列表的接口

html

<view class="toolbar">
 <view class="timestamp">{{item.timetype}}</view>
 <!-- 点赞 如果islove==1，图片变为点赞的图片-->
 <view class="like" @tap="like(index,item.id)">
 <image :src="item.islove==1?'../../static/images/lllllike.png':'../../static/images/llike.png'"></image>
 </view>
 <!-- 评论 -->
 <view class="comment" @tap="comment(index,item.id)">
 <image src="../../static/images/pinglun.png"></image>
 </view>
</view>
<!-- 赞／评论区 -->
<view class="post-footer">
 <!-- 点赞区 -->
 <view class="footer_content" v-if="item.lovelist.length>0">
 <image class="liked" src="../../static/images/likelike.png"></image>
 <text class="nickname" v-for="(love,love_index) of item.lovelist" :key="love_index">{{love.name}},</text>
 </view>
 <!-- 评论区 -->
 <view class="footer_content" v-if="item.community_on.length>0" v-for="(comment,comment_index) in item.community_on" :key="comment_index">
 <text class="comment-nickname">{{comment.nickname}}: <text class="comment-content">{{comment.content}}</text></text>
 </view>
 <!-- 当评论发送成功之后实时渲染出来评论列表-->
 <view class="footer_content" v-if="commentStatus && index==commentIndex">
 <text class="comment-nickname">{{realtimename}}: <text class="comment-content">{{realtimecontent}}</text></text>
