UniApp design and development skills for realizing login page and registration page

With the rapid development of the mobile Internet, APP has become an indispensable part of people's lives. UniApp, as a cross-platform development framework based on Vue.js, provides a solution for quickly developing multi-terminal applications. This article will introduce the design and development techniques of UniApp to implement login page and registration page, and provide corresponding code examples.

1. Design the login page
The login page is the first page for users to enter the APP, so its design should be concise and clear, and easy for users to use. The following are some tips for designing login pages:

1.1 Page layout:
Login pages usually include a logo, input boxes, buttons and other auxiliary functions. They can be placed in a suitable position using flex layout. The logo should be located in the middle of the page, and the input boxes and buttons need to be placed appropriately below the logo.

1.2 Input box settings:
The login page usually contains two input boxes, one for the user to enter the account number, and the other for the user to enter the password. To improve user experience, you can set appropriate prompt text for the input box and add input validation rules. For example, for the account input box, you can verify whether it is a legal mobile phone number; for the password input box, you can require that the password complexity must contain numbers and letters.

1.3 Button style:
The login button should be highlighted and the style is eye-catching. You can use different background colors or borders to differentiate between button states. After clicking the button, you can add some animation effects to improve the user experience.

2. Develop login page

Next, we will use UniApp to implement a basic login page. The following is a code example of a simple login page:

<template>
  <view class="login-page">
    <view class="logo"></view>
    <input class="input" type="text" v-model="account" placeholder="请输入手机号" />
    <input class="input" type="password" v-model="password" placeholder="请输入密码" />
    <button class="login-btn" @click="login">登录</button>
  </view>
</template>

<script>
  export default {
    data() {
      return {
        account: '',
        password: ''
      }
    },
    methods: {
      login() {
        // 在这里实现登录逻辑
      }
    }
  }
</script>

<style>
  .login-page {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    height: 100vh;
    background-color: #f0f0f0;
  }

  .logo {
    width: 100px;
    height: 100px;
    background-color: #333;
  }

  .input {
    width: 200px;
    height: 40px;
    margin-top: 10px;
    border: 1px solid #333;
    border-radius: 4px;
    padding: 4px;
  }

  .login-btn {
    width: 200px;
    height: 40px;
    margin-top: 20px;
    background-color: #333;
    color: #fff;
    border-radius: 4px;
  }
</style>

In the above code, the login page is implemented by a flex layout, with a logo, account input box, password input box and login button. Through the v-model directive, bind the input box to the data attribute of the Vue instance to obtain the account number and password entered by the user. When the login button is clicked, the login method will be triggered, and the user can write login logic in the method.

3. Design the registration page
The registration page is the page where users register their accounts, and it is also the first page that users come into contact with. The following are some tips for designing a registration page:

3.1 Verification code:
Requiring users to enter a verification code is a common registration method. You can add a Get Verification Code button to the registration page. After clicking the button, the user will receive a text message or email containing a verification code, and enter the verification code in the input box.

3.2 Registration Agreement:
On the registration page, you can add a check box for the user to agree to the registration agreement. And add a link to the registration agreement in the registration button. Users can click the link to view the registration agreement.

3. Develop the registration page

Next, we will use UniApp to implement a basic registration page. The following is a code example of a simple registration page:

<template>
  <view class="register-page">
    <view class="logo"></view>
    <input class="input" type="text" v-model="account" placeholder="请输入手机号" />
    <input class="input" type="password" v-model="password" placeholder="请输入密码" />
    <input class="input" type="text" v-model="verificationCode" placeholder="请输入验证码" />
    <button class="get-code" @click="getCode">获取验证码</button>
    <view class="agreement">
      <checkbox class="checkbox" v-model="checked">我已阅读并同意</checkbox>
      <text class="link">注册协议</text>
    </view>
    <button class="register-btn" @click="register">注册</button>
  </view>
</template>

<script>
  export default {
    data() {
      return {
        account: '',
        password: '',
        verificationCode: '',
        checked: false
      }
    },
    methods: {
      getCode() {
        // 在这里实现获取验证码逻辑
      },
      register() {
        // 在这里实现注册逻辑
      }
    }
  }
</script>

<style>
  .register-page {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    height: 100vh;
    background-color: #f0f0f0;
  }

  .logo {
    width: 100px;
    height: 100px;
    background-color: #333;
  }

  .input {
    width: 200px;
    height: 40px;
    margin-top: 10px;
    border: 1px solid #333;
    border-radius: 4px;
    padding: 4px;
  }

  .get-code {
    width: 200px;
    height: 40px;
    margin-top: 10px;
    background-color: #f60;
    color: #fff;
    border-radius: 4px;
  }

  .agreement {
    display: flex;
    align-items: center;
    margin-top: 10px;
  }

  .checkbox {
    margin-right: 5px;
  }

  .link {
    color: #f60;
  }

  .register-btn {
    width: 200px;
    height: 40px;
    margin-top: 20px;
    background-color: #333;
    color: #fff;
    border-radius: 4px;
  }
</style>

In the above code, the registration page is implemented by a flex layout and includes the logo, account input box, password input box, verification code input box, and get Verification code button, registration agreement checkbox, and registration button. Similarly, through the v-model directive, the input box is bound to the data attribute of the Vue instance to obtain the account number, password and verification code entered by the user. When clicking the get verification code button and registration button, the corresponding method will be triggered, and the user can implement the corresponding logic in the method.
