    在使用WebStorm前把字符编码等等设置好!
    使用WebStorm打开vue项目等待ide索引加载完成


    注意要让WebStorm可以创建vue文件需要以下步骤:

    <template>
    
    </template>
    
    <style>
    
    </style>
    
    <script>
        export default {
            data: {
    
            },
            methods: {
                
            }
        }
    </script>
    

    demo1 构建一个简单的Vue导航栏菜单实例

    1.新建组件文件夹(pages)及文件(index、userCenter、userInfo):

    index.vue代码:

    <template>
        <div>
            <p>这是首页</p>
        </div>
    </template>
    
    <style>
        p{
            display: block;
            background: #ffe87c;
        }
    </style>
    
    <script>
        export default {}
    </script>
    

    userCenter.vue代码:

    <template>
        <div>
            <p>这是个人中心</p>
            <router-link to="/userCenter/userInfo">用户信息</router-link>
            <router-view></router-view>
        </div>
    </template>
    
    <style>
        p{
            display: block;
            background: #d6e9c6;
        }
    </style>
    
    <script>
        export default {}
    </script>
    </style>
    

    userInfo.vue代码:

    <template>
        <div>
            <p>我的名字是:Heaton</p>
        </div>
    </template>
    
    <style>
        p{
            display: block;
            background: #77FFFF;
        }
    </style>
    
    <script>
        export default {}
    </script>
    

    2.在路由配置文件中,导入新建的组件。(index.js我们不用了)

    在router文件夹下新建router.js代码:

    import Vue from 'vue'
    import Router from 'vue-router'
    import Hello from '../components/HelloWorld'
    import Index from '../pages/index'
    import UserCenter from '../pages/userCenter'
    import UserInfo from '../pages/userInfo'
    
    Vue.use(Router)
    
    export default new Router({
        routes: [
            {
                path: '/',
                name: 'Hello',
                component: Hello
            },
            {
                path: '/index',
                name: 'index',
                component: Index
            },
            {
                path: '/userCenter',
                name: 'userCenter',
                component: UserCenter,
                children: [
                    {
                        path: 'userInfo',
                        name: 'userInfo',
                        component: UserInfo
                    }
                ]
            }
        ]
    })
    
    

    3. 在项目入口App.vue中建立导航栏,代码如下:

    App.vue代码:

    <template>
      <div id="app">
        <img src="./assets/logo.png">
        <p>这可以看做是导航栏</p>
        <router-link to="/index">首页</router-link>
        <router-link to="/userCenter">个人中心</router-link>
        <router-view></router-view>
      </div>
    </template>
    
    <script>
    export default {
      name: 'App'
    }
    </script>
    
    <style>
    #app {
      font-family: 'Avenir', Helvetica, Arial, sans-serif;
      -webkit-font-smoothing: antialiased;
      -moz-osx-font-smoothing: grayscale;
      text-align: center;
      color: #2c3e50;
      margin-top: 60px;
    }
    </style>
    
    4.修改mian.js

    将import router from './router'
    改为import router from './router/router.js'

    5.启动项目
    npm run dev
    


    6.错误总结
    WebStorm的js文件报错:Export/Import declarations are not supported by current JavaScript version


    .Vue 文件 ES6 语法 webstorm 中的一个识别Bug


    添加 type 类型 指明为: text-ecmascript-6 亲测有效。

    type="text-ecmascript-6"
