vuex下state数据的存储

1。在src文件下创建一个store文件，里面加入一个store.js文件
。内容大致为

import vuex from 'vuex'import Vue from 'vue'Vue.use(vuex)export default new vuex.Store({    /*state必须*/    state:{        user:{}    },    mutations:{        setUser(state,v){            state.user=v;        }    }})

2。在main.js中的vue实例中必须引入，例

import Vue from 'vue'import App from './App'import router from './router'import ElementUI from 'element-ui'import 'element-ui/lib/theme-default/index.css'import * as api from './config'import mycom from './components/index'import store from './store/store'Vue.prototype.$api = apiVue.config.productionTip = falseVue.use(ElementUI)Vue.use(mycom)Vue.test = function () {  alert()}/* eslint-disable no-new */new Vue({  el: '#app',  router,  store:store,  template: '<App/>',  components: { App }})

3。在看在哪里引用setUser方法，例如在login.vue中引用，一般在methods中会用到，如

<template>  <div>    <el-input v-model="user.username"></el-input>    <el-input v-model="user.password"></el-input>    <el-input v-model="user.checkcode"></el-input>    <img :src="codeurl" alt="">    <!--<el-button type="sucess" @click="loginUser">提交</el-button>-->   <!-- <a href="#/demo/111">111</a>    <a href="#/demo/222">222</a>-->    <router-link to="/demo/222">2222</router-link>    <router-link to="/demo/111">1111</router-link>  </div></template><script>  export default{    data () {      return {        user: {          username: '',          password: '',          checkcode: ''        },        codeurl: ''      }    },    methods: {      loginUser () {        this.$store.commit('setUser',this.user)        this.$router.push('/demo/11')        /*this.$api.login(this.user).then(function (res) {          console.log(res.data)        })*/      }    }  }</script><style scoped></style>

其中setUser名字必须对应，名字随意，但最好为英文
