通过在`van-badge-group`上设置`active-key`属性来控制选中的`badge`

|
|
|
```html
|
|
<van-badge-group :active-key="activeKey">
|
|
<van-badge title="热销榜" @click="onClick"></van-badge>
|
|
<van-badge title="花式寿司" @click="onClick" info="8"></van-badge>
|
|
<van-badge title="火炽寿司" @click="onClick" info="99"></van-badge>
|
|
<van-badge title="手握寿司" @click="onClick" info="199"></van-badge>
|
|
</van-badge-group>
|
|
```
|
|
|
|
``` javascript
|
|
export default {
|
|
data() {
|
|
return {
|
|
activeKey: 0
|
|
};
|
|
},
|
|
methods: {
|
|
onClick(key) {
|
|
this.activeKey = key;
|
|
}
|
|
}
|
|
};
|
|
```
