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

<view> <view>{{item.timetype}}</view> <!-- 点赞 如果islove==1，图片变为点赞的图片--> <view @tap="like(index,item.id)"> <image :src="item.islove==1?'../../static/images/lllllike.png':'../../static/images/llike.png'"></image> </view> <!-- 评论 --> <view @tap="comment(index,item.id)"> <image src=""></image> </view> </view> <!-- 赞／评论区 --> <view> <!-- 点赞区 --> <view v-if="item.lovelist.length>0"> <image src=""></image> <text v-for="(love,love_index) of item.lovelist" :key="love_index">{{love.name}},</text> </view> <!-- 评论区 --> <view v-if="item.community_on.length>0" v-for="(comment,comment_index) in item.community_on" :key="comment_index"> <text>{{comment.nickname}}: <text>{{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 v-if="commentStatus && index==commentIndex"> <text>{{realtimename}}: <text>{{realtimecontent}}</text></text> </view> </view>
