vue 的组件开发，以及swiper,axios的使用

父组件
<template>
  <div>
    <home-header :city="city"></home-header>   //给子组件传递值
  	<home-swiper :list='swiperList'></home-swiper>
  	<home-icons :icons="iconList"></home-icons>
  	<home-recommend :list="recommendList"></home-recommend>
    <home-weekend :list="weekendList"></home-weekend>
  </div>
</template>

<script>
import HomeHeader from './components/Header'
import HomeSwiper from './components/Swiper'
import HomeIcons from './components/Icons'
import HomeRecommend from './components/Recommend'
import HomeWeekend from './components/Weekend'
import axios from 'axios'
export default {
  name: 'Home',

  components: { 
  	HomeHeader,
  	HomeSwiper,
  	HomeIcons,
  	HomeRecommend,
    HomeWeekend
  },
  data (){
    return {
      city:'',
      swiperList:[],
      iconList:[],
      recommendList:[],
      weekendList:[]
    }
    
  },
  methods:{
    getHomeInfo(){
      axios.get('/api/index.json')
        .then(this.getHomeInfoSucc)
    },
    getHomeInfoSucc(res){
      res=res.data;
      if(res.res && res.data){
        let data=res.data;
        this.city =data.city;
        this.swiperList = data.swiperList;
        this.iconList = data.iconList;
        this.recommendList = data.recommendList;
        this.weekendList = data.weekendList;
      }
    }
  },
  mounted(){
    this.getHomeInfo();
  }	
}
</script>

<style>

</style>

　　子组件

<template>
	<div class="icons">
		<swiper :options="swiperOption">//使用swiper插件
			<swiper-slide  v-for="(page,index) of pages" :key="index">
				<div class="icon" v-for="item of page"  :key="item.id">
					<div class="iconImg" :key="item.id"   >
						<img :src="item.imgUrl" class="icon-img-content">
					</div>
					<p class="icon-desc">{{item.desc}}</p>
				</div>
				
			</swiper-slide>
		</swiper>
	</div>
</template>

<script>
	export default {
		name: 'HomeIcons',
		props:{          //获取父组件传递的值
			icons:Array
		},
		data (){
			return {
				swiperOption:{
					autoplay:false
				}
			}
		},
		 computed: {
		    pages () {
		      const pages = []
		      this.icons.forEach((item, index) => {
		        const page = Math.floor(index / 8)
		        if (!pages[page]) {
		          pages[page] = []
		        }
		        pages[page].push(item)
		      })
		      return pages
		    }
		  }
	}
</script>
