vue-demo(初級)

在使用WebStorm前把字符編碼等等設置好!
使用WebStorm打開vue項目等待ide索引加載完成


注意要讓WebStorm可以創建vue文件需要以下步驟:

<template>

</template>

<style>

</style>

<script>
    export default {
        data: {

        },
        methods: {
            
        }
    }
</script>

demo1 構建一個簡單的Vue導航欄菜單實例

1.新建組件文件夾（pages）及文件（index、userCenter、userInfo）：

index.vue代碼：

<template>
    <div>
        <p>這是首頁</p>
    </div>
</template>

<style>
    p{
        display: block;
        background: #ffe87c;
    }
</style>

<script>
    export default {}
</script>

userCenter.vue代碼：

<template>
    <div>
        <p>這是個人中心</p>
        <router-link to="/userCenter/userInfo">用戶信息</router-link>
        <router-view></router-view>
    </div>
</template>

<style>
    p{
        display: block;
        background: #d6e9c6;
    }
</style>

<script>
    export default {}
</script>
</style>

userInfo.vue代碼：

<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，導入新建的組件。（index.js我們不用了）

在router文件夾下新建router.js代碼：

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. 在項目入口App.vue中建立導航欄，代碼如下：

App.vue代碼:

<template>
  <div id="app">
    <img src="./assets/logo.png">
    <p>這可以看做是導航欄</p>
    <router-link to="/index">首頁</router-link>
    <router-link to="/userCenter">個人中心</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

將import router from './router'
改為import router from './router/router.js'

5.啟動項目

npm run dev

6.錯誤總結

WebStorm的js文件報錯：Export/Import declarations are not supported by current JavaScript version

.Vue 文件 ES6 語法 webstorm 中的一個識別Bug

添加 type 類型 指明為: text-ecmascript-6 親測有效。

type="text-ecmascript-6"

第二種解決辦法:
注釋掉build里面webpack.base.conf.js里的el規范配置
