Vue3.0实现todolist-通过计算属性获取vuex中定义的todolist的数据

import { useStore } from 'vuex'

setup() {
    let store= useStore()
    console.log(store)
    let list=computed(()=>{
      return store.state.list
    })
    return {
      list
    };
  },

<div>{{list}}</div>

<template>
  <div>
    <nav-header></nav-header>
    <nav-main></nav-main>
    <nav-footer></nav-footer>
    <div>{{ list }}</div>
  </div>
</template>
<script>
import NavHeader from "@/components/navHeader/NavHeader.vue";
import NavMain from "@/components/navMain/NavMain.vue";
import NavFooter from "@/components/navFooter/NavFooter.vue";
import { defineComponent, ref, computed } from "vue";
import { useStore } from "vuex";
export default defineComponent({
  name: "Home",
  props: {},
  components: {
    NavHeader,
    NavMain,
    NavFooter,
  },
  setup() {
    let store = useStore();
    console.log(store);
    let list = computed(() => {
      return store.state.list;
    });
    return {
      list,
    };
  },
});
</script>
<style></style>

import { createApp } from 'vue'
import App from './App.vue'
import store from './store'
const app = createApp(App)
app.use(store)
app.mount("#app")

import { createStore } from 'vuex'
export default createStore({
    //定义所需要的状态的
    state: {
        list:[
            {
                title: "吃饭",
                complete: false,
              },
              {
                title: "睡觉",
                complete: false,
              },
              {
                title: "打豆豆",
                complete: true,
              },
        ]
    },
    mutations: {
        //添加任务
        addTodo(state,payload){
            state.list.push(payload)
        },
        //删除任务 splice(下标，个数)
        delTodo(state,payload){
            state.list.splice(payload,1)
        },
        //清除已完成
        clear(state,payload){
            //把过滤之后的数组传进来
            state.list=payload
        }
    },
    actions: {
    },
    //模块化
    modules: {
    }
})
