二.Vue2.5开发去哪儿网app城市列表页③——Better-scroll的使用和字母表布局

插件链接https://github.com/ustbhuangyi/better-scroll

安装Better-scroll

npm install better-scroll --save

这是Better-scroll插件结构要求，所以我们要在list下还要添加一个总div使其成为此格式

<div class="wrapper">
  <ul class="content">
    <li>...</li>
    <li>...</li>
    ...
  </ul>
  <!-- you can put some other DOMs here, it won't affect the scrolling -->
</div>

ref可以帮助我们获取DOM，所以在list类处添加

ref='wrapper'

然后在DOM挂载后创建一个Bscroll实例来使用这个DOM

  mounted () {
    this.scroll = new Bscroll(this.$refs.wrapper)
  }

总代码

<template>
  <div class="list" ref="wrapper">
    <div>
      <div class="area">
        <div class="title border-topbottom">当前城市</div>
        <div class="button-list">
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
        </div>
      </div>
      <div class="area">
        <div class="title border-topbottom">热门城市</div>
        <div class="button-list">
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
