1 分析

根据华为网页的布局，我们大体上可以将其划分为7个盒子，如下，由于写一个这样的网页再加上部分动态效果，需要的时间很长，本篇博客只记录了div1、div2、div3的静态效果+轮播图的实现。

2 顶部盒子的实现

想要实现的正是最上部那个黑色的圆框

2.1 思路

我的思路很简单，用四个盒子，其中最大的盒子也就是整个黑色框，大盒子里面包裹着小盒子，每个小盒子对应一个字段（集团网站、选择区域/语言、登录），排版布局，则需要三个小盒子，依次向左浮动（float:left;）。或者大盒子单独采用display:flex；布局

我看了一下华为公司的代码，他是用的一个盒子，里面包裹了3个a标签，我用div习惯了，所以用的是div。

2.2 代码实现

  <div class="top_container">
        <div class="container_div1">
          集团网站
        </div>
        <div class="container_div2">
          选择区域/语言
        </div>
        <div class="container_div3">
          登录
        </div>
  </div>

.div_top {
  height: 25px;
  width: 100%;
  position: static;
  text-align: right;
  background-color: #111111;
}
.top_container {
  width: 300px;
  height: 25px;
  float: right;
  margin-right: 70px;
  display: flex;
  flex-direction: row;
  /* background-color: red; */
}
.container_div1 {
  width: 80px;
  height: 25px;
  /* background-color: aqua; */
  margin-right: 10px;
  line-height: 25px;
  font-size: 10px;
  text-align: center;
  color: #ffffff;
  cursor: pointer;
}
.container_div2 {
  width: 140px;
  height: 25px;
  /* background-color: aqua; */
  line-height: 25px;
  font-size: 10px;
  text-align: center;
  color: #ffffff;
  cursor: pointer;
}
.container_div3 {
  width: 60px;
  height: 25px;
  margin-left: 10px;
  /* background-color: aqua; */
  line-height: 25px;
  font-size: 10px;
  text-align: center;
  color: #ffffff;
  cursor: pointer;
}

3 头部盒子的实现

正是此处

3.1 思路

首先分成了三个大盒子，分别对应左、中、右三个组件，其中每一个字段或者图标都对应一个小盒子。其中中间容器的那些小盒子都需要不同的样式，因为他有一个悬浮的效果，悬浮的时候，会有一个红色的底框，而且长度各不同。

所以我为每个盒子设置了不同的宽高。

华为采用的是ul-li的形式，我本来写的是没有动态的数据，我还得自己写数组，好麻烦，还不如写div轻松。后来想想，用不着写数据，还是ul-li好用一些

3.2 代码实现

 <div class="div_header">
      <div class="header_left">
        <a class="header_logo">
          <img src="@/assets/huawei_logo.png" alt="">

4 轮播图的实现

4.1 思路

这里颇费了一些周章，轮播图还算好实现的，毕竟可以直接使用Swiper。

但是这里还是有一些特别的点，主要如下：

• 鼠标的移入移出，前进后退的显示与隐藏
• 了解更多按钮的镶嵌
• 轮播图分页器形式的改变（由点变成了狭长的长方形）

我们各个击破

4.1.1 使用轮播图

轮播图的教程网站

首先需要引入，在终端输入

npm install swiper

然后再使用的地方import

import "swiper/swiper-bundle.min.css";  // 所有 Swiper 样式，包括所有模块样式（如导航、分页等）
import Swiper, { Navigation, Pagination, Scrollbar, Autoplay } from "swiper"; // 导入您需要的模块

只需要在mounted的时候，写下如下代码便可使用

 mounted() {
        new Swiper(".swiper", {
            speed: 500,//播放的速度
            // spaceBetween: 2000,// 轮播图之间的间距
            loop: true,//是否循环播放
            autoplay: {
                delay: 2000,//自动播放的间隔
            },
            modules: [Navigation, Pagination, Scrollbar, Autoplay],
            navigation: {
                nextEl: ".swiper-button-next",//前一个按钮
                prevEl: ".swiper-button-prev",//后一个按钮
            },
            scrollbar: {
                el: ".swiper-scrollbar",
                draggable: true,
            },
            pagination: {
                el: '.swiper-pagination',
                clickable: true,
                bulletClass : 'my-bullet',//需设置.my-bullet样式
                bulletActiveClass: 'my-bullet-active',
            },
        });

    <div class="div_swiper">
        <div class="swiper" @mousemove="showSwiperButton()" @mouseout="hiddenSwiperButton()">
            <div class="swiper-wrapper">
                <div class="swiper-slide">
                    <img class="slide_img" src="@/assets/huawei-cloud-discount-pc.jpg" />
                    <button class="img_btn">了解更多</button>
                </div>
                <div class="swiper-slide">
                    <img class="slide_img" src="@/assets/vmall-mate50-series-3.jpg" />
                    <button class="img_btn">了解更多</button>
                </div>
            </div>
            <div class="swiper-button-prev" id="prev"></div>
            <!--左箭头。如果放置在swiper外面，需要自定义样式。-->
            <div class="swiper-button-next" id="next"></div>
            <!--右箭头。如果放置在swiper外面，需要自定义样式。-->
            <div class="swiper-pagination"></div>
            <!--分页器。如果放置在swiper外面，需要自定义样式。-->
        </div>
    </div>

4.1.2 前进后退的隐藏与显示

这里很显然用到鼠标事件，当鼠标移入的时候，设置一个方法，让前进后退按钮显示出来，当鼠标移出的时候，将前进后退设置为隐藏，当然前进后退初始是隐藏的。

methods:
{
       showSwiperButton() {
       let d1 = document.getElementById('prev');
       d1.style.cssText = "display:block;"
       let d2 = document.getElementById('next');
       d2.style.cssText = "display:block;"
},
		hiddenSwiperButton() {
	    let d1 = document.getElementById('prev');
        d1.style.cssText = "display:none;"
        let d2 = document.getElementById('next');
        d2.style.cssText = "display:none;"
        }
    }

同时绑定Swiper盒子，当鼠标移入Swiper盒子的时候显示，移出Swiper盒子的时候隐藏

<div class="swiper" @mousemove="showSwiperButton()" @mouseout="hiddenSwiperButton()"></div>

4.1.3 了解更多按钮的实现

看到这个图的时候，我就清楚，显然是要在了解更多的position上下功夫，让图片的盒子沾满父盒子的空间，而了解更多按钮则采用absolute定位，让其相对父组件定位。

4.1.4 轮播图分页器样式

轮播图的分页器一般都是圆点样式，如上。如何修改轮播图分页器的样式呢？我参考了Swiper的文档，发现可以修改分页器的类名，进而可以修改它的样式。

这里要注意的一点是，再修改的时候，尽量在原有的基础上修改，就是先看看他默认的样式是什么样的，然后在此基础上增加我自己的样式，这样的话，不会影响分页器的排版。

.my-bullet{
    width: var(--swiper-pagination-bullet-width,var(--swiper-pagination-bullet-size,100px));
    height: var(--swiper-pagination-bullet-height,var(--swiper-pagination-bullet-size,3px));
    display: inline-block;
    background: var(--swiper-pagination-bullet-inactive-color,#000);
    opacity: var(--swiper-pagination-bullet-inactive-opacity, .2);
    margin: 0 7px;
    cursor: pointer;
    border: 0;
}

修改正在加载的样式

.my-bullet-active{
    background: #ffffff;
    opacity: 1;
}

同时要在mounted里面，修改一下

  pagination: {
                el: '.swiper-pagination',
                clickable: true,
                bulletClass : 'my-bullet',//需设置.my-bullet样式
                bulletActiveClass: 'my-bullet-active',
            },

4.2 代码实现

我把轮播图单独写成了一个组件

Home.vue

    <div class="div_swiper">
        <div class="swiper" @mousemove="showSwiperButton()" @mouseout="hiddenSwiperButton()">

                    <img class="slide_img" src="@/assets/huawei-cloud-discount-pc.jpg" />
                    <button class="img_btn">了解更多</button>
                </div>
                <div class="swiper-slide">
                    <img class="slide_img" src="@/assets/vmall-mate50-series-3.jpg" />
                    <button class="img_btn">了解更多</button>
