                在組件xx.vue文件中取值 ``` 第一種 computed:{ count(){ return this.$store.state.count } count1(){ return this.$store.state.count1 } } ``` 簡寫xx.vue文件中 ``` 第二種 import?{?mapState?}?from"vuex" computed:mapState({ count : 'count', count1 : 'count1' }) ``` ``` 第三種 computed : mapState({ ['count','count1'] }) 哪如果要計算其他怎樣辦? ``` ``` ...{ count(){ return this.$store.state.count } count1(){ return this.$store.state.count1 } } computed :{ total(){ return this.arr.reduce((prev,curr)=>{ return curr + prev }) } ...mapState(['count','count1']) } ```
