vue实现点击关注之后及时更新列表

Posted 2020-11-20 beileixinqing

如图，我要实现点击关注之后列表及时更新成最新的列表。

思路很简单，主要是两点：

1、在点击关注之后去执行一个请求新的关注列表的action；

2、在vue组件中watch监听已关注列表和推荐关注列表

 

主要代码如下：

组件：

关注的methods:

followMethod(item){
          if(this.token){
            this.$store.dispatch(‘follow‘,{followUserId:item.pubId,page:this.page,size:this.size});
            this.$set(item,"followStatus",true);
//            this.$store.dispatch(‘refreshFollowList‘,{page:0,size:this.size});
          }else{
            Toast({
              message: "请先登录",
              duration: 800
            });
            setTimeout(function () {
              this.$router.push(‘/login‘);
            },800)
          }
      },

watch:

followList(curVal, oldVal){
        console.log(curVal)
      },
      userFollowList(curVal, oldVal){
        console.log(curVal)
      },

 

 

followList.js vuex的列表module文件：

action:

follow({dispatch,commit},payload){
    axios({
      method:"post",
      url:"web/follow/add",
      headers: {‘w-auth-token‘: Cookies.get(‘token‘)},
      params:{
        page:payload.page,
        size:payload.size
      },
      data:{
        followUserId:payload.followUserId
      }
    }).then((res) => {
      Toast("关注成功");
      return dispatch(‘refreshFollowList‘)
    }).catch((error) => {
      Toast("关注出错，请重试！");
    });
  }

refreshFollowList({state,commit}){
    if(token){
      axios.all([
        axios({
          method:"get",
          url:"web/pub/recommend",
          headers: {‘w-auth-token‘: token},
        }),
        axios({
          method:"get",
          url:"web/pub/list_pub_and_top_news",
          headers: {‘w-auth-token‘: Cookies.get(‘token‘)},
        })
      ]).then(axios.spread(function(res1,res2){
        commit("REFRESHFOLLOWLIST",res1);
        commit("REFRESHUSERFOLLOWLIST",res2);
      }));
    }else{
      axios({
        method:"get",
        url:"web/pub/recommend",
      }).then(function(res){
        commit("REFRESHFOLLOWLIST",res);
      });
    }
  },

mutation:

const mutations = {
  REFRESHFOLLOWLIST(state,res){
      state.followList=res.data.content;
      state.totalPages=res.data.totalPages;
  },
  REFRESHUSERFOLLOWLIST(state,res){
    state.userFollowList=res.data.content;
    state.userTotalPages=res.data.userTotalPages;
  },
};
