### 禁用状态
|
||
|
||
按钮不可用状态。
|
||
|
||
:::demo 你可以使用`disabled`属性来定义按钮是否可用，它接受一个`Boolean`值。
|
||
|
||
```html
|
||
<el-row>
|
||
<el-button disabled>默认按钮</el-button>
|
||
<el-button type="primary" disabled>主要按钮</el-button>
|
||
<el-button type="success" disabled>成功按钮</el-button>

||
<el-button type="info" disabled>信息按钮</el-button>
|
||
<el-button type="warning" disabled>警告按钮</el-button>
|
||
<el-button type="danger" disabled>危险按钮</el-button>
|
||
</el-row>
|
||
|
||
<el-row>
|
||
<el-button plain disabled>朴素按钮</el-button>
|
||
<el-button type="primary" plain disabled>主要按钮</el-button>
|
||
<el-button type="success" plain disabled>成功按钮</el-button>

```

### 文字按钮
|
||
|
||
没有边框和背景色的按钮。
|
||
|
||
:::demo
|
||
```html
|
||
<el-button type="text">文字按钮</el-button>
|
||
<el-button type="text" disabled>文字按钮</el-button>
|
||
```
|
||
:::
|
||
|
||
### 图标按钮
|
||
|
||
带图标的按钮可增强辨识度（有文字）或节省空间（无文字）。
|
||
|
||
:::demo 设置`icon`属性即可，icon 的列表可以参考 Element Plus 的 icon 组件，也可以设置在文字右边的 icon ，只要使用`i`标签即可，可以使用自定义图标。
|
||
|
||
```html
|
||
<el-button type="primary" icon="el-icon-edit"></el-button>
|
||
<el-button type="primary" icon="el-icon-share"></el-button>
|
||
<el-button type="primary" icon="el-icon-delete"></el-button>
|
||
<el-button type="primary" icon="el-icon-search">搜索</el-button>
|
||
<el-button type="primary">上传<i class="el-icon-upload el-icon--right"></i></el-button>
|
||
```
|
||
:::
|
||
|
||
### 按钮组
|
||
|
||
以按钮组的方式出现，常用于多项类似操作。
|
||
|
||
:::demo 使用`<el-button-group>`标签来嵌套你的按钮。
|
||
|
||
```html
|
||
<el-button-group>
|
||
<el-button type="primary" icon="el-icon-arrow-left">上一页</el-button>
|
||
<el-button type="primary">下一页<i class="el-icon-arrow-right el-icon--right"></i></el-button>
|
||
</el-button-group>
|
||
<el-button-group>
|
||
<el-button type="primary" icon="el-icon-edit"></el-button>
|
||
<el-button type="primary" icon="el-icon-share"></el-button>
|
||
<el-button type="primary" icon="el-icon-delete"></el-button>
|
||
</el-button-group>
|
||
```
|
||
:::
|
||
|
||
### 加载中
|
||
|
||
点击按钮后进行数据加载操作，在按钮上显示加载状态。
|
||
|
||
:::demo 要设置为 loading 状态，只要设置`loading`属性为`true`即可。
|
||
|
||
```html
|
||
<el-button type="primary" :loading="true">加载中</el-button>
|
||
```
|
||
:::
|
||
|
||
### 不同尺寸
|
||
|
||
Button 组件提供除了默认值以外的三种尺寸，可以在不同场景下选择合适的按钮尺寸。
|
||
|
||
:::demo 额外的尺寸：`medium`、`small`、`mini`，通过设置`size`属性来配置它们。
|
||
|
||
```html
|
||
