## Swipe 轮播
|
|
|
|
### 使用指南
|
|
``` javascript
|
|
import { Swipe, SwipeItem } from 'vant';
|
|
|
|
Vue.use(Swipe).use(SwipeItem);
|
|
```
|
|
|
|
### 代码演示
|
|
|
|
#### 基础用法
|
|
通过`autoplay`属性设置自动轮播间隔
|
|
|
|
```html
|
|
<van-swipe :autoplay="3000" indicator-color="white">
|
|
<van-swipe-item>1</van-swipe-item>
|
|
<van-swipe-item>2</van-swipe-item>
|
|
<van-swipe-item>3</van-swipe-item>
|
|
<van-swipe-item>4</van-swipe-item>
|
|
</van-swipe>
|
|
```
|
|
|
|
#### 图片懒加载
|
|
配合 [Lazyload](#/zh-CN/lazyload) 组件实现图片懒加载
|
|
|
|
```html
|
|
<van-swipe :autoplay="3000">
|
|
<van-swipe-item v-for="(image, index) in images" :key="index">
|
|
<img v-lazy="image" />
|
|
</van-swipe-item>
|
|
</van-swipe>
|
|
```
|
|
|
|
```javascript
|
|
export default {
|
|
data() {
|
|
return {
|
|
images: [
|
|
'https://img.yzcdn.cn/1.jpg',
|
|
'https://img.yzcdn.cn/2.jpg'
|
|
]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
#### 监听 change 事件
|
|
|
|
```html
|
|
<van-swipe @change="onChange">
|
|
<van-swipe-item>1</van-swipe-item>
|
|
<van-swipe-item>2</van-swipe-item>
|
|
<van-swipe-item>3</van-swipe-item>
|
|
<van-swipe-item>4</van-swipe-item>
|
|
</van-swipe>
|
|
```
|
|
|
|
```js
|
|
export default {
|
|
methods: {
|
|
onChange(index) {
|
|
Toast('当前 Swipe 索引：' + index);
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
#### 纵向滚动
|
|
|
|
```html
|
|
<van-swipe :autoplay="3000" vertical>
|
|
<van-swipe-item>1</van-swipe-item>
|
|
<van-swipe-item>2</van-swipe-item>
|
|
<van-swipe-item>3</van-swipe-item>
|
|
<van-swipe-item>4</van-swipe-item>
|
|
</van-swipe>
|
|
```
|
|
|
|
#### 控制滑块大小
|
|
|
|
```html
|
|
<van-swipe :autoplay="3000" :width="300">
|
|
<van-swipe-item>1</van-swipe-item>
|
|
<van-swipe-item>2</van-swipe-item>
|
|
<van-swipe-item>3</van-swipe-item>
|
|
<van-swipe-item>4</van-swipe-item>
|
|
</van-swipe>
|
|
```
|
|
|
|
#### 自定义指示器
|
|
|
|
```html
|
|
<van-swipe @change="onChange">
|
|
<van-swipe-item>1</van-swipe-item>
|
|
<van-swipe-item>2</van-swipe-item>
|
|
<van-swipe-item>3</van-swipe-item>
|
|
<van-swipe-item>4</van-swipe-item>
|
|
|
|
<div class="custom-indicator" slot="indicator">
|
|
{{ current + 1 }}/4
|
|
</div>
|
|
</van-swipe>
|
|
```
|
|
|
|
```js
|
|
export default {
|
|
data() {
|
|
return {
|
|
current: 0
|
|
}
|
|
},
