## 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>
|
||
```

<div class="infinite-list-wrapper" style="overflow:auto">
|
||
<ul
|
||
class="list"
|
||
v-infinite-scroll="load"
|
||
infinite-scroll-disabled="disabled">
|
||
<li v-for="i in count" class="list-item">{{ i }}</li>
|
||
</ul>
|
||
<p v-if="loading">加载中...</p>
|
||
<p v-if="noMore">没有更多了</p>
|
||
</div>
|
||
</template>
|
||
|
||
<script>
|
||
export default {
|
||
data () {
|
||
return {
|
||
count: 10,
|
||
loading: false
|
||
}
|
||
},
|
||
computed: {
|
||
noMore () {
|
||
return this.count >= 20
|
||
},
|
||
disabled () {
|
||
return this.loading || this.noMore
|
||
}
|
||
},
|
||
methods: {
|
||
load () {
|
||
this.loading = true
|
||
setTimeout(() => {
|
||
this.count += 2
|
||
this.loading = false
|
||
}, 2000)
|
||
}
|
||
}
|
