我们提供了通用的[项目模板](https://github.com/ElementUI/element-starter),你可以直接使用。对于熟悉 [cooking](https://github.com/ElementUI/element-cooking-starter) 或 [Laravel](https://github.com/ElementUI/element-in-laravel-starter) 的用户,我们也准备了相应的模板,同样可以直接下载使用。

新建项目,项目结构为
|
|
|
|
|
```text
|
|
|
|
|
|- src/ --------------------- 项目源代码
|
2016-10-28 21:35:05 +08:00
|
|
|
|
|- App.vue
|
2016-10-28 15:31:19 +08:00
|
|
|
|
|- main.js -------------- 入口文件
|
|
|
|
|
|- .babelrc ----------------- babel 配置文件
|
|
|
|
|
|- index.html --------------- HTML 模板
|
|
|
|
|
|- package.json ------------- npm 配置文件
|
|
|
|
|
|- README.md ---------------- 项目帮助文档
|
|
|
|
|
|- webpack.config.json ------ webpack 配置文件
|
|
|
|
|
```
|
|
|
|

### 引入 Element
|
|
|
|
|
|
|
|
|
|
你可以引入整个 Element,或是根据需要仅引入部分组件。我们先介绍如何引入完整的 Element。
|
2016-08-30 19:30:58 +08:00
|
|
|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
#### 完整引入
|
|
|
|
|
|
|
|
|
|
在 main.js 中写入以下内容:
|
2016-08-30 19:30:58 +08:00
|
|
|
|
```javascript
|
2016-10-28 15:31:19 +08:00
|
|
|
|
import Vue from 'vue'
|
|
|
|
|
import ElementUI from 'element-ui'
|
|
|
|
|
import 'element-ui/lib/theme-default/index.css'
|
|
|
|
|
import App from './App.vue'
|
|
|
|
|
|
|
|
|
|
Vue.use(ElementUI)
|
2016-08-30 19:30:58 +08:00
|
|
|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
new Vue({
|
|
|
|
|
el: '#app',
|
|
|
|
|
render: h => h(App)
|
|
|
|
|
})
|
2016-08-30 19:30:58 +08:00
|
|
|
|
```
|
2016-10-28 15:31:19 +08:00
|
|
|
|
以上代码便完成了 Element 的引入。需要注意的是,样式文件需要单独引入。
|
2016-08-30 19:30:58 +08:00
|
|
|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
#### 按需引入
|
2016-07-27 14:15:02 +08:00

|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
借助 [babel-plugin-component](https://github.com/QingWei-Li/babel-plugin-component),我们可以只引入需要的组件,以达到减小项目体积的目的。
|
2016-07-27 14:15:02 +08:00
|
|
|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
首先,安装 babel-plugin-component:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
npm install babel-plugin-component -D
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
然后,将 .babelrc 修改为:
|
2016-08-30 19:30:58 +08:00
|
|
|
|
```json
|
|
|
|
|
{
|
2016-10-28 15:31:19 +08:00
|
|
|
|
"presets": [
|
|
|
|
|
["es2015", { "modules": false }]
|
|
|
|
|
],
|
|
|
|
|
"plugins": [["component", [
|
2016-08-30 19:30:58 +08:00
|
|
|
|
{
|
|
|
|
|
"libraryName": "element-ui",
|
|
|
|
|
"styleLibraryName": "theme-default"
|
|
|
|
|
}
|
|
|
|
|
]]]
|
|
|
|
|
}
|
|
|
|
|
```
|

|
|
|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
如果你只希望引入部分组件,比如 Button 和 Select,那么需要在 main.js 中写入以下内容:
|
|
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
|
import Vue from 'vue'
|
|
|
|
|
import { Button, Select } from 'element-ui'
|
|
|
|
|
import App from './App.vue'
|
|
|
|
|
|
|
|
|
|
Vue.component(Button.name, Button)
|
|
|
|
|
Vue.component(Select.name, Select)
|
|
|
|
|
/* 或写为
|
|
|
|
|
* Vue.use(Button)
|
|
|
|
|
* Vue.use(Select)
|
|
|
|
|
*/
|
|
|
|
|
|
|
|
|
|
new Vue({
|
|
|
|
|
el: '#app',
|
|
|
|
|
render: h => h(App)
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 多语言设置

|
|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
Element 组件内部默认使用中文,若希望使用其他语言,则需要进行多语言设置。以英文为例,在 main.js 中:
|
2016-09-23 08:27:29 +08:00
|
|
|
|
|
2016-10-28 21:35:05 +08:00
|
|
|
|
```javascript
|
2016-10-28 15:31:19 +08:00
|
|
|
|
// 完整引入 Element
|
|
|
|
|
import Vue from 'vue'
|
|
|
|
|
import ElementUI from 'element-ui'
|
|
|
|
|
import locale from 'element-ui/lib/locale/lang/en'
|
2016-09-23 08:27:29 +08:00
|
|
|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
Vue.use(ElementUI, { locale })
|
|
|
|
|
```
|
2016-09-23 08:27:29 +08:00
|
|
|
|
|
2016-10-28 15:31:19 +08:00
|
|
|
|
或
|
2016-09-23 08:27:29 +08:00
|
|
|
|
|
2016-10-28 21:35:05 +08:00
|
|
|
|
```javascript
|
2016-10-28 15:31:19 +08:00
|
|
|
|
// 按需引入 Element
|
|
|
|
|
import Vue from 'vue'
|
|
|
|
|
import { Button, Select } from 'element-ui'
|
|
|
|
|
import lang from 'element-ui/lib/locale/lang/en'
|
|
|
|
|
import locale from 'element-ui/lib/locale'
|
|
|
|
|
|
|
|
|
|
// 设置语言
|
|
|
|
|
locale.use(lang)
|
|
|
|
|
|
|
|
|
|
// 引入组件
|
|
|
|
|
Vue.component(Button.name, Button)
|
|
|
|
|
Vue.component(Select.name, Select)
|
|
|
|
|
```
|
|
|
|
|
|
2016-10-31 12:25:19 +08:00
|
|
|
|
如果使用其它语言,默认情况下中文语言包依旧是被引入的,可以使用 webpack 的 IgnorePlugin 忽略掉它以减少打包后的文件体积。
|
2016-10-28 21:35:05 +08:00
|
|
|
|
|
|
|
|
|
webpack.config.js
|
|
|
|
|
```javascript
|
|
|
|
|
{
|
|
|
|
|
plugins: [
|
2016-11-07 16:54:20 +08:00
|
|
|
|
new webpack.IgnorePlugin(/element-ui\/lib\/locale\/lang\/zh-CN/)
|
2016-10-28 21:35:05 +08:00
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|

|

|
|
### 开始使用
|
|
|
|
|
|
|
|
|
|
至此,一个基于 Vue 和 Element 的开发环境已经搭建完毕,现在就可以编写代码了。启动开发模式:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# 执行如下命令后访问 localhost:8086
|
|
|
|
|
npm run dev
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
编译:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
npm run build
|
2016-09-23 08:27:29 +08:00
|
|
|
|
```
|
2016-10-28 15:31:19 +08:00
|
|
|
|
各个组件的使用方法请参阅它们各自的文档。
