Vue学习笔记-项目开发3.6Ajax获取数据（城市数据，同个数据多地使用）

城市组件

//City.vue
<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.handleGetCityInfoSucc)
    },
    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>

子组件

//City.vue
<template>
  <div>
    <city-header></city-header>
    <city-search></city-search>
    <city-list :cities = "cities" :hot = "hotCities"></city-list>
    <city-alphabet :cities="cities"></city-alphabet>
 
  </div>
</template>

子组件数据显示

//CityList
//只包括这篇讲的AJAX数据接收 不包括之前的那个better-scroll
 
<script>
export default {
  name: 'CityList',
  props: {
    hot: Array,
    cities: Object
  }
}
</script>
<div class="area" v-for="(item, key) of cities" :key="key">
    <div class="title border-topbottom">{{key}}</div>
    <div class="item-list" v-for="innerItem of item" :key="innerItem.id">
        <div class="item border-bottom">{{innerItem.name}}</div>
</div>

//CityAlphabet
<template>
  <ul class="list">
    <li class="item" v-for="(item, key) of cities" :key="key">{{key}}</li>
  </ul>
</template>
<script>
export default {
  name: 'CityAlphabet',
  props: {
    cities: Object
  }
}
</script>
