调整首页细节

  1. 固定头部
    App.vue中代码
    
    <style>
    body{
    padding: 0;
    margin:0;
    margin-top: 80px;
    } </style> Header中代码: <style scoped>
    .header{
    top:0;
    left:0;
    right:0;
    margin: auto;
    background-color: #fff;
    height: 80px;
    z-index: 1000;
    position: fixed;
    box-shadow: 0 0.5px 0.5px 0 #c9c9c9;
    } </style>
  2. 调整轮播图左右两边的按钮
    注意,style标签中要设置全局样式,所以不需要scoped
    <style>
    .el-carousel__arrow{
    width: 100px!important;
    height: 100px!important;
    }
    .el-icon-arrow-left{
    font-size: 35px;
    margin-left: 50px;
    }
    .el-carousel__arrow--left{
    left: -50px;
    }
    </style>

在组件目录components下创建Course.vue组件文件,代码如下:

  1. <template>
    <div class="course"> </div>
    </template> <script>
    export default {
    name: "Course",
    data(){
    return { }
    },
    }
    </script> <style scoped> </style>
  2. 在routers/index.js路由中注册路由
    import Vue from "vue"
    import Router from "vue-router" // 导入可以被用户访问的组件
    import Home from "@/components/Home"
    import Course from "@/components/Course" Vue.use(Router); export default new Router({
    mode: "history",
    routes:[
    // 路由列表
    {
    path: "/",
    name: "Home",
    component:Home,
    },
    {
    path: "/home",
    name: "Home",
    component:Home,
    },
    {
    path: "/course",
    name: "Course",
    component:Course,
    }, ]
    })
  3. 完成免费课课程列表
    文件代码结构,Course.vue代码
    <template>
    <div class="course">
    <Header/>
    <div class="main">
    <!-- 筛选功能 -->
    <div class="top">

购物车页面

  1. 在头部公共组件中打通购物车的链接地址,Header.vue
    <span><router-link to="/cart">购物车</router-link></span>
  2. 
    

    创建购物车页面组件
    在components/创建Cart.vue组件文件

  3. 注册路由地址
    routers/index.js代码
    import Cart from "@/components/Cart"
    
    export default new Router({
    // 路由跳转模式,注意使用 history
    mode: "history", // 路由规则
    routes:[
    。。。
    ,{
    name:"Cart",
    path: "/cart",
    component: Cart,
    },
    ]
    })
  4. 显示表格数据
    <template>
    <div class="cart">
    <Header/>
    <div class="main">
    <div class="cart-title">
