## Button 按钮
|
|
|
|
### 使用指南
|
|
``` javascript
|
|
import { Button } from 'vant';
|
|
|
|
Vue.use(Button);
|
|
```
|
|
|
|
### 代码演示
|
|
|
|
#### 按钮类型
|
|
|
|
支持`default`、`primary`、`info`、`warning`、`danger`五种类型，默认为`default`
|
|
|
|
```html
|
|
<van-button type="default">默认按钮</van-button>
|
|
<van-button type="primary">主要按钮</van-button>
|
|
<van-button type="info">信息按钮</van-button>
|
|
<van-button type="warning">警告按钮</van-button>
|
|
<van-button type="danger">危险按钮</van-button>
|
|
```
|
|
|
|
#### 朴素按钮
|
|
|
|
通过`plain`属性将按钮设置为朴素按钮，朴素按钮的文字为按钮颜色，背景为白色。
|
|
|
|
```html
|
|
<van-button plain type="primary">朴素按钮</van-button>
|
|
<van-button plain type="danger">朴素按钮</van-button>
|
|
```
|
|
|
|
#### 细边框
|
|
|
|
设置`hairline`属性可以开启 0.5px 边框，基于伪类实现
|
|
|
|
```html
|
|
<van-button plain hairline type="primary">细边框按钮</van-button>
|
|
<van-button plain hairline type="danger">细边框按钮</van-button>
|
|
```
|
|
|
|
#### 禁用状态
|
|
|
|
通过`disabled`属性来禁用按钮，此时按钮不可点击
|
|
|
|
```html
|
|
<van-button disabled type="primary">禁用状态</van-button>
|
|
<van-button disabled type="danger">禁用状态</van-button>
|
|
```
|
|
|
|
#### 加载状态
|
|
|
|
```html
|
|
<van-button loading type="primary" />
|
|
<van-button loading type="danger" loading-text="加载中..." />
|
|
```
|
|
|
|

|
|
|
```html

|
|
