## 快速上手
|
|||
|
|
|||
|
本节将介绍如何在项目中使用 Element。
|
|||
|
|
|||
|
### 使用 vue-cli@3
|
|||
|
|
|||
|
我们为新版的 vue-cli 准备了相应的 [Element 插件](https://github.com/ElementUI/vue-cli-plugin-element),你可以用它们快速地搭建一个基于 Element 的项目。
|
|||
|
|
|||
|
### 使用 Starter Kit
|
|||
|
|
|||
|
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 Laravel 用户,我们也准备了相应的[模板](https://github.com/ElementUI/element-in-laravel-starter),同样可以直接下载使用。
|
|||
|
|
|||
|
如果不希望使用我们提供的模板,请继续阅读。
|
|||
|
|
|||
|
### 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。
|
|||
|
|
|||
|
#### 完整引入
|
|||
|
|
|||
|
在 main.js 中写入以下内容:
|
|||
|
|
|||
|
```javascript
|
|||
|
import Vue from 'vue';
|
|||
|
import ElementUI from 'element-ui';
|
|||
|
import 'element-ui/lib/theme-chalk/index.css';
|
|||
|
import App from './App.vue';
|
|||
|
|
|||
|
Vue.use(ElementUI);
|
|||
|
|
|||
|
new Vue({
|
|||
|
el: '#app',
|
|||
|
render: h => h(App)
|
|||
|
});
|
|||
|
```
|
|||
|
|
|||
|
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。
|
|||
|
|
|||
|
#### 按需引入
|
|||
|
|
|||
|
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。
|
|||
|
|
|||
|
首先,安装 babel-plugin-component:
|
|||
|
|
|||
|
```bash
|
|||
|
npm install babel-plugin-component -D
|
|||
|
```
|
|||
|
|
|||
|
然后,将 .babelrc 修改为:
|
|||
|
|
|||
|
```json
|
|||
|
{
|
|||
|
"presets": [["es2015", { "modules": false }]],
|
|||
|
"plugins": [
|
|||
|
[
|
|||
|
"component",
|
|||
|
{
|
|||
|
"libraryName": "element-ui",
|
|||
|
"styleLibraryName": "theme-chalk"
|
|||
|
}
|
|||
|
]
|
|||
|
]
|
|||
|
}
|
|||
|
```
|
|||
|
|
|||
|
接下来,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)
|
|||
|
});
|
|||
|
```
|
|||
|
|
|||
|

|

|||

|
|||
|
|
|||
|
Vue.prototype.$loading = Loading.service;
|
|||
|
Vue.prototype.$msgbox = MessageBox;
|
|||
|
Vue.prototype.$alert = MessageBox.alert;
|
|||
|
Vue.prototype.$confirm = MessageBox.confirm;
|
|||
|
Vue.prototype.$prompt = MessageBox.prompt;
|
|||
|
Vue.prototype.$notify = Notification;
|
|||
|
Vue.prototype.$message = Message;
|
|||
|
```
|
|||
|
|
|||
|
### 全局配置
|
|||
|
|
|||
|
在引入 Element 时,可以传入一个全局配置对象。该对象目前支持 `size` 与 `zIndex` 字段。`size` 用于改变组件的默认尺寸,`zIndex` 设置弹框的初始 z-index(默认值:2000)。按照引入 Element 的方式,具体操作如下:
|
|||
|
|
|||
|
完整引入 Element:
|
|||
|
|
|||
|
```js
|
|||
|
import Vue from 'vue';
|
|||
|
import Element from 'element-ui';
|
|||
|
Vue.use(Element, { size: 'small', zIndex: 3000 });
|
|||
|
```
|
|||
|
|
|||
|
按需引入 Element:
|
|||
|
|
|||
|
```js
|
|||
|
import Vue from 'vue';
|
|||
|
import { Button } from 'element-ui';
|
|||
|
|
|||
|
Vue.prototype.$ELEMENT = { size: 'small', zIndex: 3000 };
|
|||
|
Vue.use(Button);
|
|||
|
```
|
|||
|
|
|||
|
按照以上设置,项目中所有拥有 `size` 属性的组件的默认尺寸均为 'small',弹框的初始 z-index 为 3000。
|
|||
|
|
|||
|
### 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。各个组件的使用方法请参阅它们各自的文档。
|
|||
|
|
|||
|
### 使用 Nuxt.js
|
|||
|
|
|||
|
我们还可以使用 [Nuxt.js](https://nuxtjs.org):
|
|||
|
|
|||
|
<div class="glitch-embed-wrap" style="height: 420px; width: 100%;">
|
|||
|
<iframe src="https://glitch.com/embed/#!/embed/nuxt-with-element?path=nuxt.config.js&previewSize=0&attributionHidden=true" alt="nuxt-with-element on glitch" style="height: 100%; width: 100%; border: 0;"></iframe>
|
|||
|
</div>
|
|||
|
|
