## Uploader 图片上传
|
|
|
|
### 使用指南
|
|
``` javascript
|
|
import { Uploader } from 'vant';
|
|
|
|
Vue.component(Uploader.name, Uploader);
|
|
```
|
|
|
|
### 代码演示
|
|
|
|
#### 基础用法
|
|
|
|
```html
|
|
<van-uploader :afterRead="logContent">
|
|
<van-icon name="photograph" />
|
|
</van-uploader>
|
|
```
|
|
|
|
```javascript
|
|
export default {
|
|
methods: {
|
|
logContent(file) {
|
|
console.log(file)
|
|
}
|
|
}
|
|
};
|
|
```
|
|
|
|
#### 设置 Input 属性
|
|
可以直接在 Uploader 上设置 accpet 等原生属性，input 会自动继承该属性
|
|
|
|
```html
|
|
<van-uploader :afterRead="logContent" accept="image/gif, image/jpeg">
|
|
<van-icon name="photograph" />
|
|
</van-uploader>
|
|
```
