vue2 introduces better-scroll, instantiation:
const wrapper = document.querySelector(".wrapper")
const scroll = new BScroll(".wrapper",{
  click:true
})
 < template > 
 < div class= "singer" > 
<div class="wrapper">
  <div class="content">
     <ul>
        <li v-for="item in singerList"></li>
     </ul>
  </div>
</div>
 < / div > 
 < / template > 
 .singer {
 position: fixed; 
 width: 100%; 
 top: 60px; 
 bottom: 0; 
} 
 .wrapper {
 height: 100%; 
 overflow: hidden; 
} 
 then 
 
 
 but I can"t scroll. How should I write it? I"m learning. I don"t know much. Thank you very much.
