状态管理 达到了数据共享

import { createStore } from 'vuex'export default createStore({  //定义所需要的状态的  state: {    name:'jack'  },  //同步修改state 都是方法 用来做异步操作 包括定时器 发请求  //第一个参数state 第二个参数是需要修改的值  mutations: {    setName(state,payload){      state.name=payload      state.name.slice(0,1)    }  },  //异步提交mutation  //第一个参数是store对象 第二个参数是修改的值  actions: {    asyncSetName(store,params){      setTimeout(()=>{        //commit是提交mutation 调用mutation的方法        store.commit('setName',params)      },2000)    }  },  //模块化的  modules: {      }})
