Kilikili首页布局设计1(仿照Bilibili)

目录

前言:模仿Bilibili的首页样式自己设计一个网页布局拥有动态配合,需要CSS+HTML+JS,用到serilize插件和bootstrap插件,用户的信息暂时存放在本地存储.这次没有用到接口,将会在后部分中使用。使用接口编写一个天气预报。注意有主页面登录页面还有注册页面三个页面

引入两个插件和axios库

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"> //用于制作弹出框
 <script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>  //为后面调接口做准备
https://www.npmjs.com/package/form-serialize //收集表单数据

一、整体布局分析

1、分为三部分head,channel和body

2、head一个版心,lchannel和body一个版心

总结:先整体再局部,从上到下,从左到右

二、具体代码

1、head设计

思路:分为三个部分,左边首页到下载客户端,中间搜索框,右边用户头像到投稿。并且加上背景图片

1.1 html设计

<div class="head">
    <!-- head背景图片 -->
    <div class="headbgi">
        <div class="wrapper">
            <!-- logo -->
            <div class="logo"><h1><a href="https://www.bilibili.com/?spm_id_from=333.1007.0.0" class="iconfont icon-bilibili"></a></h1></div>
            <!-- 左边小导航 -->
            <div class="headleft">
                <ul>
                    <li><a href="https://www.bilibili.com/?spm_id_from=333.1007.0.0" class="firsttu" target="_blank"><span class="iconfont icon-bilibili-line"></span><p class="firstzi">首页</p></a></li>
                    <li><a href="#"><p>番剧</p></a></li>
                    <li><a href="#"><p>直播</p></a></li>
                    <li><a href="#"><p>游戏中心</p></a></li>
                    <li><a href="#"><p>会员购</p></a></li>
                    <li><a href="#"><p>漫画</p></a></li>
                    <li><a href="#"><p>赛事</p></a></li>
                    <li><a href="#"><p>畅玩S13</p></a></li>
                    <li><a href="#" class="lasttu"><span class="iconfont icon-bottom"></span><p class="downzi">下载客户端</p></a></li>
                </ul>
            </div>
            <!-- 搜索框 -->
            <div class="headmid">
                <input type="text" placeholder="Clannad">
                <span class="iconfont icon-suosou"></span>
            </div>
            <!-- 右边用户功能 -->
            <div class="headright">
                <ul>
                    <div class="header-login-entry"><span> 登录 </span></div>
                    <li><a href="#"><span class="iconfont icon-wodedahuiyuan"></span><p class="firstzi">大会员</p></a></li>
                    <li><a href="#"><span class="iconfont icon-xinxi"></span><p class="firstzi">消息</p></a></li>
                    <li><a href="#"><span class="iconfont icon-dongtai"></span><p class="firstzi">动态</p></a></li>
                    <li><a href="#"><span class="iconfont icon-shoucang"></span><p class="firstzi">收藏</p></a></li>
                    <li><a href="#"><span class="iconfont icon-lishijilu"></span><p class="firstzi">历史</p></a></li>
                    <li><a href="#"><span class="iconfont icon-chuangzuozhongxin"></span><p class="firstzi">创作中心</p></a></li>
                    <li><a href="#" class="tougao"><span class="iconfont icon-shangchuan"></span><p class="firstzi">投稿</p></a></li>
                </ul>
            </div>
        </div>
    </div>
  </div>

}

1.3 JS设计

document.querySelector('.header-login-entry').addEventListener('click', e => {
    // console.log(123)
    location.href = './login.html'
})
// 登录成功后登录按钮消失变成用户随机头像
const uname = localStorage.getItem('uname')
const pwd = localStorage.getItem('pwd')
// console.log(uname,pwd)
if (uname && pwd ) {
    // console.log(123)
    document.querySelector('.header-login-entry').innerHTML = `<img src="./images/userimg.jpg" alt="">`
} else (
    document.querySelector('.header-login-entry').innerHTML = `<span> 登录 </span>`

)

1.4 遇到的问题总结

1.4.1 问题1

图标和字要垂直居中对齐,而且图标要调整垂直距离

解决方法:给图标和字外面再套一个盒子,盒子flex弹性盒子并且改变主轴方向,水平居中,垂直居中,图标设置line-height行高调整

1.4.2 问题2

设置head的上边距的时候出现背景图也移动了,这是因为子标签会跟父标签的边框会重合

解决方法:给父级加上边的内边距1px;给父级添加overflow:hidden;为父元素或者子元素声明绝对定位;或者给子标签加内边距

1.4.3 问题3

给投稿项设置样式的时候需要再设置图标在左,字在右边

解决方法:给图标元素添加flex-direction:inherit;继承a的位置元素flex

1.4.4 问题4

设置背景图片后浏览器缩小后背景图片没显示全部,背景图会变动

解决方法:在设置背景图片的选择器里面再加上min-width:你的浏览器的最宽宽度;

2、channel设计

思路:一个大盒子,里面放三个小盒子,采用ul嵌套li的方式布局,记得弹性盒子,还用gird网格布局

1.1 html设计

  <!-- 频道区域channel -->
  <div class="main">
    <div class="wrapper">
        <div class="channel">
            <div class="iconfontpic">

                    <span class="title">动态</span>
                    </a>
                </div>
                <div class="iconfontright">

1.3 JS设计

待定

1.4 遇到的问题总结

1.用ul嵌套li的方式布局,发现22个li怎么换行,一行11,B站用的是网格布局grid。学习一下grid

3、body设计

1.1 html设计

 <div class="mainvideo">
    <div class="wrapper">
        <div class="swiper">
            <div class="img">
                <a target="_blank" href="https://www.bilibili.com/bangumi/play/ss1539?spm_id_from=333.337.0.0"><img src="./images/lunbo1.png" alt=""></a>

1.4 遇到的问题总结

1.设置轮播图


      // 再声明一个函数放自动播放间隔函数
      function againStart() {
        // 这里再停止定时器是一个习惯,要开启前一定要先关掉
        // 这个是为了防止一打开 网页鼠标就在块上,定时器还没
        // 关闭后再开启是新的定时器,所以逻辑上一个新的定时器应该先关闭再开启
        clearInterval(ti)
        ti = setInterval(function() {
        i++
        if (i === sliderData.length) {
            i = 0
        }
        trans()
    }, 3000)
    }

2.引入JS文件报错,找不到图片标签

得把引入的标签写在</body>上面,也就是说得等页面加载出来那些图片之后,才可以获取到

3.播放量的图标怎么设置成透明的,也能看到视频的

检查才发现,我忘记把背景颜色去掉了

4.遍历循环出现结构不一致

用了结构伪类选择器解决了,选择后面三个设置不一样的结构就可以了
.mainvideo .topVideoRight ul li:nth-child(n+4) {
  margin-top: 10px;
}

5.怎么判断有没有值然后显示用户头像呢

// 登录成功后登录按钮消失变成用户随机头像
const uname = localStorage.getItem('uname')
const pwd = localStorage.getItem('pwd')
// console.log(uname,pwd)
//if (uname !== '' && pwd !== '')
if (uname && pwd ) {
    // console.log(123)
    document.querySelector('.header-login-entry').innerHTML = `<img src="./images/userimg.jpg" alt="">`
} else (
    document.querySelector('.header-login-entry').innerHTML = `<span> 登录 </span>`

)
//注意这里取不到本地存储,本地存储时null,null也不等于空字符,所以会成立,所以直接判断有没有就行

4、login和register设计

这里简略放一些主要在后部分补充

CSS部分

Login
css
body {
  background-image: url(../images/headbgi2.jpg);
}

h1 {
  color: #fff;
}

.register {
  /* margin: auto; */
  margin-left: 900px;
}

.form {
   margin-top: 40px;
   margin-left: 530px;
    display: flex;
    flex-direction: column;
    width: 400px;
    /* margin: auto; */
}


register

body {
  background-image: url(../images/headbgi2.jpg);
}
.form {
  margin-top: 40px;
  margin-left: 525px;
    display: flex;
    flex-direction: column;
    width: 400px;
    /* margin: auto; */
}
/* 提示框 */
.alert{
  margin-top: 100px;
  /* margin-right: 100px; */
    width: 400px;
    position: fixed;
    top: 100px;
    left: 50%;
    transform: translateX(-50%);
    display: none;
  }
.show{
    display: block !important;
  }

JS部分

login

// 还没注册先注册
const register = document.querySelector('.register')
register.addEventListener('click', e => {
    // console.log(123)
    location.href = 'register.html'
})


const form = document.querySelector('.form')
form.addEventListener('click', e => {
    e.preventDefault()   //组织默认事件
})

// 点击登录后跳转到首页
document.querySelector('.form .login').addEventListener('click', e => {
    // console.log(123)
    const formDataObj = serialize(form, {hash:true,empty:true})
    // console.log(formDataObj.uname)
    // console.log(localStorage.getItem('uname'))
    const uname = localStorage.getItem('uname')
    const pwd = localStorage.getItem('pwd')
    if (formDataObj.uname !== uname || formDataObj.uname === '') {
        // console.log(123)
    myAlert(false, '用户名不能为空或请检查用户名输入是否正确,新用户请先注册')

    }else if (formDataObj.pwd !== pwd || formDataObj.pwd === '') {
    myAlert(false, '密码不能为空或请检查密码输入是否正确,新用户请先注册')
    } else {
    myAlert(true, '登录成功')
    
    setTimeout(function(){
        location.href = '主网页.html' 
        
        }, 2000)
    }  
})

register
const form = document.querySelector('.form')
form.addEventListener('click', e => {
    e.preventDefault()   //组织默认事件
})

// 点击登录后跳转到首页
document.querySelector('.form .login').addEventListener('click', e => {
    // console.log(123)
    // 使用serialize插件收集表单数据
    const registerObj = serialize(form, {hash:true, empty:true})
    // console.log(registerObj)
    // console.log(registerObj.uname)
    // 判断不为空就存进去并且跳转
    if (registerObj.uname !== '' && registerObj.pwd !== '') {
        localStorage.setItem('uname', registerObj.uname)
        localStorage.setItem('pwd', registerObj.pwd)
        myAlert(true, '注册成功')
        setTimeout(function() {
            // console.log(123)
            location.href = 'login.html'
    
        },2000)
    }else {
        myAlert(false, '注册用户名和内容不能空,请重新输入')
        form.reset()
    }
})

三、总结(问题、想法、优化)

笔记思路最好是先静态,然后在动态业务逻辑

设置用户登录的时候,可以加一个退出登录按钮,一点击退出就跳转到首页头像消失。再登录的时候还可以用之前注册的信息再登录一次。

注册登录的时候使用正则表达式精准匹配,设置用户设用户名和密码的格式
