我正在制定VUE的时间表，我对VUE和JS都很新 . 我创建了VUE组件，它将一些新属性添加到已处于状态的对象中，然后我将此对象与getter一起使用并在我的另一个VUE组件中渲染，但不幸的是，新属性仅在重新加载后呈现 . 这是我的组件的片段，我添加了新属性
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
},
}
这是一个来自州的片段
const state = {
schedule: {}
}
这是行动
addDate ({commit}, date) {
commit('ADD_DATE', date)
}
以下是完成所有工作的突变
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，从getter获取计划
computed: {
...mapGetters([
'schedule'
])
}
所以我不能让这个吸气剂反应的问题，但我看到状态发生了变化 . 有人能帮我吗？

我，当我需要一个反应性吸气剂时，请执行以下操作：
如果要添加新属性，则需要使用Vue.set / this . $ set . 见vue docs
