好家伙，

頂不住了，太多的bug，

本來是想把背景用canvas做成動態的，但是，出現了各種問題

為了不耽誤進度，我們先把一個簡單的登錄註冊界面做出來

來看看效果：

 （看上去還不錯）

本界面使用Vue2(新建項目的時候記得把less勾上,項目里有用到)

1.項目目錄:

2.MyLogin.vue組件代碼如下:

<template>
  <div class="login-container">
    <div class="login-box">

      <!-- 頭像區域 -->
      <div class="text-center avatar-box">
        <img src="../assets/logo.png" class="img-thumbnail avatar" alt="">
      </div>

      <!-- 表單區域 -->
      <div class="form-login p-4">
        <!-- 登錄名稱 -->
        <div class="form-group form-inline">
          <label for="username">登錄名稱</label>
          <input type="text" class="form-control ml-2" id="username" placeholder="請輸入登錄名稱" autocomplete="off" v-model.trim="username"/>
        </div>
        <!-- 登錄密碼 -->
        <div class="form-group form-inline">
          <label for="password">登錄密碼</label>
          <input type="password" class="form-control ml-2" id="password" placeholder="請輸入登錄密碼" v-model.trim="password"/>
        </div>
        <!-- 登錄和重置按鈕 -->
        <div class="form-group form-inline d-flex justify-content-end">
          <button type="button" class="btn btn-secondary mr-2" @click="register">註冊</button>
          <button type="button" class="btn btn-primary" @click="login">登錄</button>
        </div>
      </div>

    </div>
  </div>
</template>

<script>
export default {
  name: 'MyLogin',
  data() {
    return {
      username:'',
      password: ''
    }
  },
  methods: {
    reset() {
      this.username = ''
      this.password = ''
    },
    login() {
      
    },
    register(){
      this.$router.push('/register')
    },
  }
}
</script>

<style lang="less" scoped>
.login-container {
  background-color: #35495e;
  height: 100%;
  .login-box {
    width: 400px;
    height: 250px;
    background-color: #fff;
    border-radius: 3px;
    position: absolute;
    left: 50%;
    top: 50%;
    transform: translate(-50%, -50%);
    box-shadow: 0 0 6px rgba(255, 255, 255, 0.5);
    .form-login {
      position: absolute;
      bottom: 0;
      left: 0;
      width: 100%;
      box-sizing: border-box;
    }
  }
}

.form-control {
  flex: 1;
}

.avatar-box {
  position: absolute;
  width: 100%;
  top: -65px;
  left: 0;
  .avatar {
    width: 120px;
    height: 120px;
    border-radius: 50% !important;
    box-shadow: 0 0 6px #efefef;
  }
}
</style>

(在綠色部分使用你想要的圖片進行替換)

3.MyRegister代碼如下:

<template>
    <div class="login-container">
        <div class="login-box">

            <!-- 頭像區域 -->
            <div class="text-center avatar-box">
                <img src="../assets/logo.png" class="img-thumbnail avatar" alt="">
            </div>

            <!-- 表單區域 -->
            <div class="form-login p-4">
                <!-- 登錄名稱 -->
                <div class="form-group form-inline">
                    <label for="username">賬戶</label>
                    <input type="text" class="form-control ml-2" id="username" placeholder="請輸入登錄名稱" autocomplete="off"
                        v-model.trim="username" />
                </div>
                <!-- 登錄密碼 -->
                <div class="form-group form-inline">
                    <label for="password">密碼</label>
                    <input type="password" class="form-control ml-2" id="password" placeholder="請輸入登錄密碼"
                        v-model.trim="password" />
                </div>
                <!-- 登錄密碼 -->
                <div class="form-group form-inline">
                    <label for="password">手機號</label>
                    <input type="phonenumber" class="form-control ml-2" id="phonenumber" placeholder="請輸入手機號"
                        v-model.trim="password" />
                </div>
                <!-- 登錄和重置按鈕 -->
                <div class="form-group form-inline d-flex justify-content-end">
                    <button type="button" class="btn btn-secondary mr-2" @click="backlogin">返回登陸界面</button>
                    <button type="button" class="btn btn-primary" @click="backlogin">註冊</button>
                </div>
            </div>

        </div>
    </div>
</template>
  
<script>
export default {
    
    name: 'MyLogin',
    data() {
        return {
            username: '',
            password: ''
        }
    },
    methods: {
        backlogin() {
            this.$router.push('/login')

        },
    }
}
</script>
  
<style lang="less" scoped>
.login-container {
  background-color: #35495e;
  height: 100%;
  .login-box {
    width: 400px;
    height: 300px;
    background-color: #fff;
    border-radius: 3px;
    position: absolute;
    left: 50%;
    top: 50%;
    transform: translate(-50%, -50%);
    box-shadow: 0 0 6px rgba(255, 255, 255, 0.5);
    .form-login {
      position: absolute;
      bottom: 0;
      left: 0;
      width: 100%;
      box-sizing: border-box;
    }
  }
}

.form-control {
  flex: 1;
}

.avatar-box {
  position: absolute;
  width: 100%;
  top: -65px;
  left: 0;
  .avatar {
    width: 120px;
    height: 120px;
    border-radius: 50% !important;
    box-shadow: 0 0 6px #efefef;
  }
}
</style>

4.路由

你已經是一個成熟的孩子了,要學會自己配路由

import Vue from "vue"
import VueRouter from "vue-router"
import pathArr from "@/router/pathArr.js";
//導入需要的組件
import Login from "@/components/MyLogin";
import Register from "@/components/MyRegister";
Vue.use(VueRouter)

const router = new VueRouter({
    routes: [
        {path: '/',redirect: '/login'},
        //登錄路由規則
        {path: '/login',component: Login},
        //後臺主頁路由規則
        
        //註冊界面路由
        {path: '/register',component: Register},
        //背景頁面

        
    ]
})

大致效果如下:
