三，列表布局

1. 在components 中新建list.vue

<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 class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <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">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
          <div class="button-wrapper">
            <div class="button">北京</div>
          </div>
        </div>
      </div>
      <div class="area">
        <div class="title border-topbottom">a</div>
        <div class="item-list">
          <div class="item border-bottom">阿里尔</div>
          <div class="item border-bottom">阿里尔</div>
          <div class="item border-bottom">阿里尔</div>
          <div class="item border-bottom">阿里尔</div>
          <div class="item border-bottom">阿里尔</div>
        </div>
      </div>
    </div>
  </div>
</template>

样式：

  @import "~styles/varibles.styl"
  .border-topbottom
    &:before
      border-color #ccc
    &:after
      border-color #ccc
  .border-bottom
  &:before
    border-color #ccc
  .list
    overflow hidden
    position absolute
    top 1.58rem
    right 0
    bottom 0
    left 0
    .title
      line-height .54rem
      padding-left .2rem
      background #eee
      color #666
      font-size .26rem
    .button-list
      padding .1rem .6rem .1rem .1rem
      overflow hidden
      .button-wrapper
        float left
        padding .1rem
        .button
          text-align center
          margin .1rem
          border .02rem solid #ccc
          border-radius .06rem
          padding .1rem .5rem
    .item-list
      .item
        line-height .76rem
        padding-left .2rem

2. 使用better-scroll 联级滚动

git地址：

安装： npm install better-scroll

使用：

citylist.vue

<div class="list" ref="wrapper">
   <div>
　　......
　　</div>
<div>

import bscroll from 'better-scroll'
export default {
  name: 'citylist',
  mounted: function () {
     //this.$refs.wrapper获取dom元素
     this.scroll = new bscroll(this.$refs.wrapper) 
  } 
}

3. 右侧字母表

新建 alphabet.vue

<template>
  <div>
    <ul class="list">
      <li class="item">a</li>
      <li class="item">a</li>
      <li class="item">a</li>
      <li class="item">a</li>
      <li class="item">a</li>
      <li class="item">a</li>
      <li class="item">a</li>
    </ul>
  </div>
</template>

<script>
export default {
  name: 'cityalphabet'
}
</script>

<style lang="stylus" scoped>
  @import "~styles/varibles.styl"
  .list
    position absolute
    right 0
    top 1.58rem
    bottom 0
    display flex
    width .4rem
    flex-direction column
    justify-content center
    .item
      text-align center
      line-height .4rem
      color $bgcolor
</style>

view code

4. 动态数据渲染

在static 目录下新建moc 文件夹，添加city.json文件

地址：https://github.com/1417766861/vue2.5-app/blob/master/travel/static/moc/city.json

发送ajax 请求：

import apiurl from '@/config/api_url'


......  
data () {
    return {
      cities: {},
      hotcities: []
    }
  },
  methods: {
    getcityinfo () {
      axios.get(apiurl.api + 'city.json')
        .then(this.handlegetcityinfosucc)
    },
    handlegetcityinfosucc (res) {
      res = res.data
      if (res.ret && res.data) {
        this.cities = res.data.cities
        this.hotcities = res.data.hotcities
      }
    }
  },
  mounted () {
    this.getcityinfo()
  }

/src/config/api_url.js

export default {
  api: '/static/moc/'
}

给组件添加数据：

    <city-list :cities="cities" :hotcities="hotcities"></city-list>
    <city-alphabet :cities="cities"></city-alphabet>

遍历显示，list.vue

      <div class="area">
        <div class="title border-topbottom">热门城市</div>
        <div class="button-list">
          <div class="button-wrapper" v-for="city in hotcities" :key="city.id">
            <div class="button">{{city.name}}</div>
          </div>
        </div>
      </div>
      <div class="area" v-for="(city,key) in cities" :key="key">
        <div class="title border-topbottom">{{key}}</div>
        <div class="item-list">
          <div class="item border-bottom" v-for="c in city" :key="c.id">{{c.name}}</div>
        </div>
      </div>

遍历显示，alphabet.vue

    <ul class="list">
      <li class="item" v-for="(item,key) in cities" :key="key">{{key}}</li>
    </ul>
