Vue3.0实现todolist-使用状态管理的api

 //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: false,
              },
        ]
        //name: 'jack'
    },

addTodo(state,payload){
            state.list.push(payload)
        },

delTodo(state,payload){
            state.list.splice(payload,1)

        },

 clear(state,payload){
            //把过滤之后的数组传进来
            state.list=payload
        }

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: {

    }
})
