IScroll使用注意点

1. IScroll组件里面跟外面都必须包裹一个跟组件
   本文档的scroll-view的外面的根组件是div,里面的根组件是ul
2. IScroll组件的position必须是fixed

<template>
  <div class="singer">
    <scroll-view>
      <ul>
        <li>233</li>
        <li v-for="value in topArtistsInfo" :key="value.key">
          {{ value.key }}
          <ul>
            <li v-for="artist in value.list" :key="artist.name">
              {{ artist }}
            </li>
          </ul>
        </li>
      </ul>
    </scroll-view>
  </div>
</template>

<style scoped>
.singer {
  position: fixed;
  top: 184px;
  left: 0;
  right: 0;
  bottom: 0;
  overflow: hidden;
  background: lightcyan;
}
</style>
