## Stepper 步进器
|
||
|
||
### 使用指南
|
||
``` javascript
|
||
import { Stepper } from 'vant';
|
||
|
||
Vue.component(Stepper.name, Stepper);
|
||
```
|
||
|
||
### 代码演示
|
||
|
||
#### 基础用法
|
||
|
||
:::demo 基础用法
|
||
```html
|
||
<van-stepper v-model="stepper1"></van-stepper>
|
||
<p class="curr-stepper">当前值：{{ stepper1 }}</p>
|
||
```
|
||
:::
|
||
|
||
#### 禁用状态
|
||
通过设置`disabled`属性来禁用 stepper
|
||
|
||
:::demo 禁用状态
|
||
```html
|
||
<van-stepper v-model="stepper1" disabled></van-stepper>
|
||
```
|
||
:::
|
||
|
||
#### 高级用法
|
||
|
||
默认是每次加减为1，可以对组件设置`step`、`min`、`max`、`defaultValue`属性
|
||
|
||
:::demo 高级用法
|
||
```html
|
||
<van-stepper v-model="stepper2" min="5" max="40" step="2" default-value="9"></van-stepper>
|
||
<p class="curr-stepper">当前值：{{ stepper2 || 9 }}</p>
|
||
```
