vue3在setup中使用mapState解读

import { computed } from "vue"
import { mapState, useStore } from "vuex"
export default function (state:any) {
    // 1. 获取实例 $store
    const store = useStore()
    // 2. 遍历状态数据
    const storeStateFns = mapState(state)
    // 3. 存放处理好的数据对象
    const storeState = {}
    // 4. 对每个函数进行computed
    Object.keys(storeStateFns).forEach(fnKey => {
        const fn = storeStateFns[fnKey].bind({ $store: store })
        // 遍历生成这种数据结构 => {name: ref(), age: ref()}
        storeState[fnKey] = computed(fn)
    })
    return storeState
}

<script lang="ts" setup>

import useMapState from "@/hooks/useMapState"

const myState:any = useMapState({
  includeList: (state: any) => state.keepAlive.includeList
})
const { includeList } = myState
</script>

import { computed } from "vue";
import { mapState, useStore } from "vuex"

export const useMapState = (getKeys) => {

    const store = useStore();
    
    const storeState = {}
    const storeFns = mapState(getKeys)

    Object.keys(storeFns).forEach((fnKeys) => {
        const fn = storeFns[fnKeys].bind({$store: store})
        storeState[fnKeys] = computed(fn)
    })

    return storeState
}

<script>
