观察原型图首页

首页组件
头部组件(小组件)
轮播图组件(小组件)
尾部组件(小组件)

首页组件使用home.vue

所有小组件写好都要在首页组件里导入注册

eg:
import Header from  '@/components/header';

export default {
  name: 'HomeView',
  components:{
    Header,
  }
}

1，编写头部组件header

<template>
    <div class="header">
        <div class="slogan">
            <p>老男孩IT教育 | 帮助有志向的年轻人通过努力学习获得体面的工作和生活</p>
        </div>
        <div class="nav">
            <ul class="left-part">
                <li class="logo">
                    <router-link to="/">
                        <img src="../assets/img/head-logo.svg" alt="">
                    </router-link>
                </li>
                <li class="ele">
                    <!-- 如果{active: url_path === '/free-course'} 条件成立则会在字体下面显示一条横线-->
                    <span @click="goPage('/free-course')" :class="{active: url_path === '/free-course'}">免费课</span>
                </li>
                <li class="ele">
                    <span @click="goPage('/actual-course')" :class="{active: url_path === '/actual-course'}">实战课</span>
                </li>
                <li class="ele">
                    <span @click="goPage('/light-course')" :class="{active: url_path === '/light-course'}">轻课</span>
                </li>
            </ul>

            <div class="right-part">
                <div>
                    <span>登录</span>
                    <span class="line">|</span>
                    <span>注册</span>
                </div>
      </div>
        </div>
    </div>

</template>

<script>

    export default {
        name: "Header",
        data() {
            return {
                // 当前所在路径，去sessionStorage取的，如果取不到，就是 /
                url_path: sessionStorage.url_path || '/',
            }
        },
        methods: {
            goPage(url_path) {
                // 判断当前页面是否不是要跳转的路由，不是就跳转
                // 已经是当前路由就没有必要重新跳转
                if (this.url_path !== url_path) {
                    this.$router.push(url_path);
                }
                sessionStorage.url_path = url_path;
            },
        },
        created() {
            // 组件加载万成，就取出当前的路径，存到sessionStorage中  this.$route.path可以取出当前路径
            sessionStorage.url_path = this.$route.path;
            // 把url_path = 当前路径
            this.url_path = this.$route.path;
        }
    }
</script>

<style scoped>
    .header {
        background-color: white;
        box-shadow: 0 0 5px 0 #aaa;
    }

    .header:after {
        content: "";
        display: block;
        clear: both;
    }

    .slogan {
        background-color: #eee;
        height: 40px;
    }

    .slogan p {
        width: 1200px;
        margin: 0 auto;
        color: #aaa;
        font-size: 13px;
        line-height: 40px;
    }

    .nav {
        background-color: white;
        user-select: none;
        width: 1200px;
        margin: 0 auto;

    }

    .nav ul {
        padding: 15px 0;
        float: left;
    }

    .nav ul:after {
        clear: both;
        content: '';
        display: block;
    }

    .nav ul li {
        float: left;
    }

    .logo {
        margin-right: 20px;
    }

    .ele {
        margin: 0 20px;
    }

    .ele span {
        display: block;
        font: 15px/36px '微软雅黑';
        border-bottom: 2px solid transparent;
        cursor: pointer;
    }

    .ele span:hover {
        border-bottom-color: orange;
    }

    .ele span.active {
        color: orange;
        border-bottom-color: orange;
    }

        float: right;
    }

    .right-part .line {
        margin: 0 10px;
    }

    .right-part span {
        line-height: 68px;
        cursor: pointer;
    }
</style>

2.轮播图小组件Banner

<template>
  <div class="banner">
    <el-carousel height="400px" :interval="5000" arrow="always">
      <el-carousel-item v-for="item in img_list" :key="item.id">
        <!--判断跳转地址是否含有http 含有则是外链不能用 router-link跳转，需要用a标签-->
        <div v-if="item.link.indexOf('http')>-1">
          <a :href="item.link">
            <img :src="item.image" :alt="item.title">
          </a>
        </div>
        <div v-else>
          <router-link :to="item.link">
            <img :src="item.image" :alt="item.title">
          </router-link>
        </div>


      </el-carousel-item>
    </el-carousel>
  </div>
</template>

<script>
export default {
  name: "Banner",
  data() {
    return {
      img_list: []
    }
  },
  created() {
    this.$axios.get(this.$settings.BASE_URL + '/home/banner/').then(res => {
      // 如果返回正确就把轮播图对象赋值给img_list
      if (res.data.code == 100) {
        this.img_list = res.data.data
      } else {
        // 200错误才会走这，不是则弹窗错误信息
        this.$message(res.data.msg)
      }
    }).catch(res => {
      // 500错误要在catch里写
      this.$message('轮播图服务器异常，请稍后再试')
    })
  }
}
</script>

<style scoped>
.el-carousel__item {
  height: 400px;
  min-width: 1200px;
}

.el-carousel__item img {
  height: 400px;
  margin-left: calc(50% - 1920px / 2);
}
</style>

3.页脚组件Footer
