  state.commentCount++
}

}

submitComment(comment) {
uni.request({

url: '后台评论接口',
data: { comment: comment },
success: (res) => {
  if (res.data.code === 0) {
    store.commit('incrementCommentCount')
  }
}

})
}

3. Display the number of comments on the page

computed: {
commentCount() {

return this.$store.state.commentCount
