vue实现点击关注后及时更新列表功能

vue实现点击关注后及时更新列表功能

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; }, };
