yb课堂 首页home开发 《三十七》

Home模块开发

拆分子组件

• Home
  • banner
  • videoList

指令属性里面取data里面的数据不用加{{}}，html标签内容体中间则需要加双花括号

创建component文件夹

　　在src/views/Home下创建component文件夹

在component目录下，分别创建Banner.vue、VideoList.vue

首页开发

Home.vue

<template>
  <div>
    <!--首页轮播图-->
    <home-banner :banners="banners"></home-banner>
    <home-video-list :videoList="videoList"></home-video-list>
    <common-footer></common-footer>
  </div>
</template>Í
<script>
import HomeBanner from "./component/Banner";
import HomeVideoList from "./component/VideoList";
import CommonFooter from "@/components/CommonFooter";
import { getBanner, getVideoList } from "@/api/getData.js";
export default {
  //注册组件
  components: {
    HomeBanner,
    HomeVideoList,
    CommonFooter
  },
  //声明数据源
  data() {
    return {
      banners: [],
      videoList: []
    };
  },
  //定义方法
  methods: {
    async getBannerData() {
      try {
        //获取轮播图数据
        const result = await getBanner();
        console.log(result)
        console.log(result.code == 0)
        if (result.data.code == 0) {
          this.banners = result.data.data;
        }
      } catch (error) {
        console.log(error);
      }
    },
    async getVList() {
      try {
        //获取视频列表
        const result = await getVideoList();
        console.log(result)
        if (result.data.code == 0) {
          this.videoList = result.data.data;
        }
      } catch (error) {
        console.log(error);
      }
    }
  },
  //页面渲染完成调用方法获取数据
  mounted() {
    this.getBannerData();
    this.getVList();
  }
};
</script>
<style lang="scss" scoped>
</style>

Banner.vue

<template>
  <div>
    <cube-slide :data="banners">
      <cube-slide-item v-for="(item, index) in banners" :key="index">

          <img :src="item.img" style="width:100%" />
        </a>
      </cube-slide-item>
    </cube-slide>
  </div>
</template>
<script>
export default {
  //获取父组件传过来的值
  props: {
    banners: {
      type: Array,
      required: true
    }
  }

<style lang="scss" scoped>
//列表包裹层边距
.list-content {
  margin-top: 20px;
  padding: 0 13px;

//视频包括层
.list {
  display: flex; //设置flex布局
  flex-wrap: wrap; //换⾏排列

  padding-bottom: 55px;
}
//视频个体层
.course {
  width: 48%;
  margin-bottom: 17px;
}
//视频图⽚
.item_img {
  font-size: 0; //消除图⽚元素产⽣的间隙
  box-shadow: 0 4px 11px 0 rgba(43, 51, 59, 0.6); //设置图⽚阴影，rgba前三个参数是颜⾊编码，最后⼀个是透明度

  img {
    width: 100%;
    border-radius: 8px;
  }
