How to use Vue and Element-plus to create a responsive user interface

1. Introduction
In modern web development, front-end frameworks play a key role. They enable us to more efficiently Build complex user interfaces. Vue is a popular JavaScript framework, and Element-plus is a Vue-based UI component library that provides a wealth of components that can be used to build responsive user interfaces. This article will introduce how to create a simple responsive user interface using Vue and Element-plus, and provide some code examples.

2. Environment setup
First, we need to build a basic Vue environment. You can easily create a new Vue project using the Vue CLI, a scaffolding tool provided by the Vue official website. Execute the following command to install Vue CLI:

$ npm install -g @vue/cli

Create a new Vue project and select the default configuration options:

$ vue create my-app

After the creation is completed, enter the project directory and run the following command to install Element-plus ：

$ cd my-app
$ npm install element-plus

3. Use Element-plus components
Element-plus provides many commonly used UI components, such as buttons, forms, tables, etc. We can build user interfaces by introducing these components.

First, we need to introduce Element-plus in Vue's entry file main.js and register it:

import { createApp } from 'vue'
import App from './App.vue'
import elementPlus from 'element-plus'
import 'element-plus/lib/theme-chalk/index.css'

createApp(App)
  .use(elementPlus)
  .mount('#app')

Now, we can use Element-plus components in Vue components.

Taking a simple form interface as an example, we can create a component named UserForm and use the Element-plus form component in it:

<template>
  <el-form :model="user" label-width="80px">
    <el-form-item label="姓名">
      <el-input v-model="user.name"></el-input>
    </el-form-item>
    <el-form-item label="年龄">
      <el-input-number v-model="user.age"></el-input-number>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submit">提交</el-button>
    </el-form-item>
  </el-form>
</template>

<script>
export default {
  data() {
    return {
      user: {
        name: '',
        age: 0
      }
    }
  },
  methods: {
    submit() {
      // 处理提交逻辑
    }
  }
}
</script>

in In the above code, we use el-form to create a form, el-input and el-input-number are used to enter name and age respectively. el-button is used to submit the form.

4. Build a responsive interface
Vue provides a responsive data binding mechanism that can update the interface in real time. We can use Vue's data binding feature to automatically update the user interface when interacting with the user.

In the above example, the v-model directive is used to bind the form input to the name and of the user object age attribute. In this way, when the user inputs, the properties of the user object will be automatically updated, thereby achieving real-time updating of the interface.

In the method of processing form submission, we can obtain the value entered by the user and process it accordingly.

methods: {
  submit() {
    console.log(this.user.name)
    console.log(this.user.age)
    // 处理提交逻辑
  }
}

Using this method, we can build a responsive user interface that displays user input in real time.

5. Summary
This article introduces how to use Vue and Element-plus to create a responsive user interface. By introducing the Element-plus component, we can quickly build a rich UI interface and use Vue's responsive data binding mechanism to achieve real-time updates of the interface. I hope this article is helpful to beginners who use Vue and Element-plus to build user interfaces.
