如何使vuex吸气剂具有反应性

Question

我按照时间表使用VUE，我对VUE和JS非常陌生。我创建了VUE组件，它将一些新属性添加到已经处于状态的对象中，然后我将这个对象与getter一起呈现在我的另一个VUE组件中，但不幸的是，新属性仅在重新加载后呈现。这是我添加新属性的组件片段

    methods: {
                ...mapActions({addDateToState: 'addDate'}),
                addDate () {
                    this.date = this.startTime.time; 
                    //date from datepicker

                    this.addDateToState({date:this.date, year:this.year, time:this.event.time, name:this.event});
                    // object need to add
                },

            }

这是国务院的一个片段

const state = {
    schedule: {}
}

以下是操作

addDate ({commit}, date) {
        commit('ADD_DATE', date)
    }

这是突变，它完成了所有的工作

    ADD_DATE (state, date) {
            if (typeof state.schedule[date.year] === 'undefined') {
                state.schedule[date.year] = {};
            }

            if (typeof state.schedule[date.year][date.date] === 'undefined') {
                state.schedule[date.year][date.date] = {};
            }
            if (typeof state.schedule[date.year][date.date][date.time] === 'undefined') {
                state.schedule[date.year][date.date][date.time] = [];
            }
            state.schedule[date.year][date.date][date.time].push(date.name)
            //interesting that this properties are reactive, so I see chenges when pushh new element to the array, but don't see if it is new property on the object

            console.log(state.schedule)
            //here I see the schedule which already has new properties so mutation works

        }

吸气剂

const getters = {
schedule() {
        return state.schedule;
    }
}

这里是计算属性，它从getters中获取时间表

computed: {
    ...mapGetters([
        'schedule'
    ])
}

所以问题是我不能使吸气剂反应，但我看到状态发生了变化。有人能帮我吗？

Answer 1

我，当我在vue a中需要一个反应型吸气剂时，请这样做:

computed: {
    getSchedule: function () { return this.schedule; }
}

Answer 2

您需要使用Vue.set/this$如果要添加新属性，请设置。查看vue文档
