Vue项目城市选择页--页面的动态数据渲染

ajax请求后台：父组件向子组件传递数据

<template>
  <div>
    <city-header></city-header>
    <city-search></city-search>
    <city-list :cities="cities" :hot="hotCities"></city-list>
    <city-alphabet></city-alphabet>
  </div>
</template>
<script>
import axios from 'axios'
import CityHeader from './components/Header'
import CitySearch from './components/Search'
import CityList from './components/List'
import CityAlphabet from './components/Alphabet'
export default {
  name: 'city',
  components: {
    CityHeader,
    CitySearch,
    CityList,
    CityAlphabet
  },
  data () {
    return {
      cities: {},
      hotCities: []
    }
  },
  methods: {
    getCityInfo () {
      axios.get('/api/city.json')
        .then(this.handleGetCity)
    },
    handleGetCityInfoSucc (res) {
      res = res.data
      if (res.ret && res.data) {
        const data = res.data
        this.cities = data.cities
        this.hotCities = data.hotCities
      }
    }
  },
  mounted () {
    this.getCityInfo()
  }
}
</script>
<style lang="stylus" scoped>
</style>

子组件接收父组件传递的数据

<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" v-for="item of hot" :key="item.id">
            <div class="button">{{item.name}}</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>
      </div>
      <div class="area" v-for="(item,key) of cities" :key="key">
        <div class="title border-topbottom">{{key}}</div>
        <div class="item-list">
          <div class="item border-bottom"  v-for="innerItem of item" :key="innerItem.id">{{innerItem.name}}</div>
        </div>
      </div>
    </div>
  </div>
</template>
