const vuex_store = new Vuex.Store({
state:{
user_name:"",mutations:{
showUserName(state){
alert(state.user_name);
},setAgree(state,agreeNum){
state.newsdetail.agree = agreeNum;
}
},actions:{
agree(context,newsid){
// 进行请求,获取点赞后的agree字段属性值
Vue.http.post("http://localhost/agree.PHP",{newsid:newsid},{emulateJSON:true}).then(function (res) {
// 处理业务
// 调用上面setAgree方法更新点赞数
context.commit("setAgree",res.body.agree);
},function(){})
}
},getters:{
getNews(state){
return state.newslist.filter(function (news) {
return !news.isdeleted;
})
}
}
})

调用actions里定义的agree方法 this.$store.dispatch("agree",this.$store.state.newsdetail.id) } }
