把上面组件拷贝一下，保存vue文件pull-refresh.vue放到你的component/common文件夹下， 然后引入到页面 , 下面是引用demo
<template><div class="home">
<v-scroll :on-refresh="onRefresh" :on-infinite="onInfinite" :loading-text="loadingText" >
<ul class="list">
<li v-for="item in articleList">{{item.title}}</li>
</ul>
</v-scroll>
</div>
</template>
<script>
