## InfiniteScroll 无限滚动
|
|
|
|
滚动至底部时,加载更多数据。
|
|
|
|
### 基础用法
|
|
|
|
在要实现滚动加载的列表上上添加`v-infinite-scroll`,并赋值相应的加载方法,可实现滚动到底部时自动执行加载方法。
|
|
:::demo
|
|
|
|
```html
|
|
<template>
|
|
<ul class="infinite-list" v-infinite-scroll="load" style="overflow:auto">
|
|
<li v-for="i in count" class="infinite-list-item">{{ i }}</li>
|
|
</ul>
|
|
</template>
|
|
|
|
<script>
|
|
export default {
|
|
data() {
|
|
return {
|
|
count: 0,
|
|
}
|
|
},
|
|
methods: {
|
|
load() {
|
|
this.count += 2
|
|
},
|
|
},
|
|
}
|
|
</script>
|
|
<!--
|
|
<setup>
|
|
|
|
import { defineComponent, ref } from 'vue';
|
|
|
|
export default defineComponent({
|
|
setup() {
|
|
const count = ref(0);
|
|
const load = () => {
|
|
count.value += 2;
|
|
};
|
|
return {
|
|
count,
|
|
load,
|
|
};
|
|
},
|
|
});
|
|
|
|
</setup>
|
|
