基于vue实现bilibili网页

学校要求的实验设计,基于vue实现bilibili网页版,可实现以下功能

(1)基本的悬浮动画和页面渲染

(2)可实现登录和未登录的页面变化

(3)在登录页面的,实现密码判断,或者短信验证方式的倒数功能

(4)实现轮播图

(5)实现预览视频(GIF)

(6)页面下拉到一定高度出现top栏以及右下角的返回功能

由于篇幅,代码较长,本文仅罗列一些基本代码,要源码的伙伴直接在本文评论即可

 1.基本页面

1.1未登录

1.2已登录 

以下是基本框架代码

2.登录页面

2.1实现锁定密码框时,左右下角图片的变化

 

 

<img src="../assets/img/login_L.png" alt="" class="e-l-img" v-if="isFocus">
            <img src="../assets/img/closeL.png" alt="" class="e-l-img" v-else>
            <img src="../assets/img/login_R.png" alt="" class="e-r-img" v-if="isFocus">
            <img src="../assets/img/closeR.png" alt="" class="e-r-img" v-else>

利用v-if即可,在获得输入框获得焦点时候,让isFocus相对应变化即可

2.2自由切换短信/密码登录

 利用点击事件切换对应变量的值即可

<el-form labor-width="150px" class="entry_Form" v-if="EntryMethod === 'mima'">
                <el-form-item label="账号" class="userInput">
                  <el-input placeholder="请输入账号" v-model="UserNameInput">el-input>
                el-form-item>
                <el-form-item label="密码" class="passInput" 
                >
                  <el-input placeholder="请输入密码" @focus="isFocus=false" @blur="isFocus=true" ref="PassInput"  :type="inputType" v-model="passWordInput" @keyup.enter.native="handleLogin">el-input>
                  <div class="p-right" v-if="!isCheck">
                    <span><i class="iconfont icon-chakanmima" @mousedown.prevent="handleEyeClose">i>span>
                    <a href="javascript:;">忘记密码？a>
                  div>
                  <div class="p-right" v-else>
                    <span><i class="iconfont icon-chakanmima1" @mousedown.prevent="handleEyeOpen">i>span>
                    <a href="javascript:;">忘记密码？a>
                  div>
                el-form-item>
              el-form>
              <el-form labor-width="150px" class="entry_Form" v-else>
                <el-form-item label="+86" class="userInput">
                  <el-input placeholder="请输入手机号" v-model="PhoneNumInput">el-input>
                  <el-divider class="en-divider" direction="horizontal">el-divider>
                  <el-button :disabled="(!isPhoneNumberValid ) || (downCount !== 0)" @click="handleGetCaptcha">{{ GetButtonText }}el-button>
                el-form-item>
                <el-form-item label="验证码" class="passInput" >
                  <el-input placeholder="请输入验证码" @focus="isFocus=false" @blur="isFocus=true" ref="passwordInput" v-model="CaptchaInput" @keyup.enter.native="handleLoginByCaptcha">el-input>
                el-form-item>
              el-form>

2.3只有当手机号输入为11位数字的时候,按钮才启动

2.4对应的错误提示弹框

 

 

 

 handleLoginByCaptcha(){
        if(this.CaptchaInput === '12345'){
          this.UserNameInput = ''
        this.passWordInput = ''
        this.$emit('changeIsLogin',true)
        this.handleClick_entryBox()
        clearInterval(this.timer_ET);
        this.downCount = 0
        }else if(this.CaptchaInput === ''){
          this.getErrorShowText = '请输入验证码'
          this.passWordError = true
          setTimeout(() => {
            this.passWordError = false;
          },1000)
        }else{
          this.getErrorShowText = '验证码错误'
          this.passWordError = true
          setTimeout(() => {
            this.passWordError = false;
          },1000)
        }
      },
      handleGetCaptcha(){
        if (!(/^\d{11}$/.test(this.PhoneNumInput))) {
          this.getErrorShowText = '请输入正确的手机号'
          this.passWordError = true
          setTimeout(() => {
            this.passWordError = false;
          },1000)
        return;
    }

2.5获取验证码倒计时

 startCountDown(){
        this.downCount = 60;
        this.timer_ET = setInterval(() => {
          if(this.downCount > 0){
            this.downCount--;
          }else{
            clearInterval(this.timer_ET);
            this.timer_ET = null
          }
        },1000)
      },

 3.底部右下角

3.1悬浮展开

 

3.2点击回到顶部

 
class="backBox" @click="scrollToTop">
        <i class="iconfont icon-jiantou_down">i>
        <div>顶部div>
