mint-ui loadmore 上拉加载的坑

<div style="height:100vh;overflow: scroll;">  
    <mt-loadmore :top-method="loadTop" :bottom-method="loadBottom" :bottom-all-loaded="allLoaded" ref="loadmore"  
    bottomPullText="上拉加载更多">  
        <ul>  
            <li v-for="(item,index) in lists" style="height:40px;">{{ item }}</li>  
        </ul>  
    </mt-loadmore>  
</div>  

1.必定要给<mt-loadmore>的父元素添加overflow:scroll属性，否则上拉加载没法使用。
