具体代码

index.js

知识点:
加载vue、elementUi
输出app、store
ES6模块主要有两个功能：export和import
export 用于对外输出本模块（一个文件可以理解为一个模块）变量的接口

var name = 'lily';
var age = 19
export {name,age
}

import 用于在一个模块中加载另一个含有export接口的模块。
也就是说使用export命令定义了模块的对外接口以后，其他JS文件就可以通过import命令加载这个模块（文件）

import {component1, component2} 按需引入，经过打包压缩后文件体积更小

export与export default的区别
1、在一个文件或模块中，export、import可以有多个，export default仅有一个
2、通过export方式导出，在导入时要加{ }，export default则不需要

import Vue from 'vue';
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';import App from './app.vue';
import store from './store';Vue.use(ElementUI);export {App,store
};

app.vue

知识点：组件components

<template><div class="register-page"><steps-bar/><register-form/></div>
</template><script>import StepsBar from "./stepsBar.vue";import RegisterForm from "./registerForm.vue";export default {components: {'steps-bar': StepsBar,'register-form': RegisterForm,}};</script><style lang="scss">html{min-width:auto;font-size: 100%;}.register-page{padding:20px;}</style>

registerForm.vue

知识点：
elementui表单及验证
vuex的mapState
store的运用

<template>
<div class="register-box"><el-form ref="registerForm" :rules="registerFormRules" :model="registerForm" label-width="110px"><div class="step0" v-if="active == 0"><el-form-item label="邀请码：" prop = "code"><el-input v-model="registerForm.code"></el-input></el-form-item></div><div class="step1" v-if="active == 1"><el-form-item label="手机号：" prop="tel"><el-input v-model="registerForm.tel"></el-input></el-form-item><el-form-item label="短信验证码：" prop="smsCode"><el-input v-model="registerForm.smsCode" class="smsCodeInput"></el-input><el-button @click.prevent="getSmsCode()">获取验证码</el-button></el-form-item></div><div class="step3" v-if="active == 2"><el-form-item label="企业名称：" prop="ent"><el-input v-model="registerForm.ent"></el-input></el-form-item><el-form-item label="姓名：" prop="name"><el-input v-model="registerForm.name"></el-input></el-form-item><el-form-item label="密码：" prop="password"><el-input type="password" v-model="registerForm.password"></el-input></el-form-item></div><div class="step4 register-success" v-if="active == 3"><i class="el-icon-circle-check" style="font-size: 32px;"></i><p>注册成功</p></div></el-form><div class="next-box" v-if="active<3"><el-button type="primary" @click="next" v-loading="registerLoading">下一步</el-button></div>
</div>

</template>

<script>

import { mapState } from 'vuex';
import { NAMESPACE, NEXT_STEP} from './vuex';export default {data(){return {registerForm: {code: 'sdada121212121',tel: '',smsCode: '',ent: '',name: '',password:''},registerFormRules: {tel:[{ required: true, message: '请输入手机号码', trigger: 'blur' },{ min: 11, max: 11, message: '请输入正确的11位手机号码', trigger: 'blur' }],smsCode:[{ required: true, message: '请输入短信验证码', trigger: 'blur' },],ent:[{ required: true, message: '请输入企业名称', trigger: 'blur' },],name:[{ required: true, message: '请输入姓名', trigger: 'blur' },],password:[{ required: true, message: '请输入密码', trigger: 'blur' },],}}},computed:{...mapState({active: state => state.register.stepsAction,registerLoading: state => state.register.registerLoading})},methods: {validate(callback) {this.$refs['registerForm'].validate((valid) => {if (valid) {callback && callback(this.registerForm);} else {console.log('error submit!!');return false;}});},next() {this.validate((data)=>{if (this.active === 2) { // 提交注册console.log(data);this.$store.dispatch(`${NAMESPACE}/registerSave`, data);} else {this.$store.commit(`${NAMESPACE}/${NEXT_STEP}`, 1);}});}}};
</script><style lang="scss" scoped>.register-box{margin:60px 20px;}.register-success{font-size: 32px;display:flex;justify-content: center;align-items: center;}.next-box{display:flex;justify-content:center;align-items:center;margin:60px 0 10px;}.smsCodeInput{width: calc(100% - 118px);}
</style>

stepsBar.vue

<template><el-steps :active="active" align-center><el-step title="邀请码"></el-step><el-step title="联系方式"></el-step><el-step title="账号信息"></el-step><el-step title="完成注册"></el-step></el-steps>
</template><script>import {mapState} from 'vuex';export default {computed:{...mapState({active: state => state.register.stepsAction})}};
</script>

store.js

知识点：
store拆分即多模块状态管理(modules)

//定义方法
export const NAMESPACE = 'register';
export default {namespaced: true,state,mutations,actions
};
// 使用方法
import { mapState } from 'vuex';
import { NAMESPACE, NEXT_STEP} from './vuex';
//监听响应式属性变化
computed:{...mapState({active: state => state.register.stepsAction})
}
//触发actions
this.$store.dispatch(`${NAMESPACE}/registerSave`, data);
//触发mutations
this.$store.commit(`${NAMESPACE}/${NEXT_STEP}`, 1);//store.js
import Vue from 'vue';
import Vuex from 'vuex';Vue.use(Vuex);import register from './vuex.js';
const store = new Vuex.Store({modules:{register}
});export default store;

vuex.js

知识点：
对象的解构赋值

const node = {loc: {start: {line: 1,column: 5}}
};let { loc, loc: { start }, loc: { start: { line }} } = node;
line // 1
loc  // Object {start: Object}
start // Object {line: 1, column: 5}    

vuex NAMESPACE:
vuex中的store分模块管理，需要在store的index.js中引入各个模块，为了解决不同模块命名冲突的问题，将不同模块的namespaced:true，之后在不同页面中引入getter、actions、mutations时，需要加上所属的模块名
mutations和actions的区别
Vuex中store数据改变的唯一方法就是mutation
actions 只是一个架构性的概念，并不是必须的，说到底只是一个函数，你在里面想干嘛都可以，只要最后触发 mutation 就行。异步竞态怎么处理那是用户自己的事情。vuex 真正限制你的只有 mutation 必须是同步的这一点

使用常量替代 Mutation 事件类型

//vuex.js
import { Message } from 'element-ui';import api from '@/api';
const { website: { register: { register: { registerHandle } } } } = api;export const NAMESPACE = 'register';export const NEXT_STEP = 'NEXT_STEP';
export const SUBMIT_LOADING = 'SUBMIT_LOADING';
export const SUBMIT_SUCCESS = 'SUBMIT_SUCCESS';
export const SUBMIT_ERROR = 'SUBMIT_ERROR';const state = {stepsAction: 0,registerLoading: false
};const mutations = {[NEXT_STEP](state, n) {state.stepsAction = state.stepsAction + n;},[SUBMIT_LOADING](state) {state.registerLoading = true;},[SUBMIT_SUCCESS](state) {state.registerLoading = false;state.stepsAction = state.stepsAction + 1;},[SUBMIT_ERROR](state, res) {state.registerLoading = false;Message.error(res.msg);}
};const actions = {registerSave({ commit, state }, data) {commit(SUBMIT_LOADING);registerHandle(data).then((response) => {if (response.status === 200) {const responseData = response.data;const result = responseData.result;if (responseData.status === 200) {commit(SUBMIT_SUCCESS, result);} else {commit(SUBMIT_ERROR, {msg: responseData.msg});}}}).catch(() => {commit(SUBMIT_ERROR, { msg: '服务器请求错误' });});}
};export default {namespaced: true,state,mutations,actions
};
