Welcome to the Vue.js guide! This is a comprehensive guide that will help you learn and understand Vue.js, a progressive JavaScript framework for building user interfaces.

简介

Vue.js is an open-source model-view-viewmodel (MVVM) framework for building dynamic and responsive single-page applications. It allows developers to create interactive UIs using HTML, CSS, and JavaScript.

特点

  • 易于上手: Vue.js has a gentle learning curve and is easy to start with.
  • 组件化: Vue.js encourages the use of components, making it easier to organize and reuse code.
  • 响应式: Vue.js has a reactive data system that allows you to create dynamic and responsive UIs.
  • 集成: Vue.js integrates well with other libraries and frameworks, such as Vuex for state management and Axios for HTTP requests.

快速开始

To get started with Vue.js, you can follow these steps:

  1. 安装 Node.js: Vue.js requires Node.js to be installed on your system.
  2. 安装 Vue CLI: Vue CLI is a command-line tool for quickly scaffolding new Vue.js projects.
    npm install -g @vue/cli
  3. 创建新项目: Use Vue CLI to create a new project.
    vue create my-vue-project
  4. 运行项目: Navigate to the project directory and run the project.
    cd my-vue-project
npm run serve

组件

Vue.js uses components to build UIs. A component is a self-contained, reusable part of the UI. You can create components by defining a template, script, and style.

创建组件

To create a new component, you can follow these steps:

  1. 定义组件: Create a new file in the src/components directory, for example, MyComponent.vue.
  2. 编写模板: The template defines the structure of the component.
    <template>
  <div>
    <h1>Hello, Vue.js!</h1>
  </div>
</template>
  3. 编写脚本: The script defines the logic of the component.
    <script>
export default {
  name: 'MyComponent',
}
</script>
  4. 使用组件: Import and use the component in your Vue.js application.

路由

Vue Router is the official router for Vue.js. It allows you to define routes and navigate between them.

安装 Vue Router

To install Vue Router, run the following command:

npm install vue-router

定义路由

To define routes, you need to create a router/index.js file and import the necessary components.

import Vue from 'vue';
import Router from 'vue-router';
import Home from '@/components/Home.vue';

Vue.use(Router);

export default new Router({
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home
    }
  ]
});

使用路由

To use the router, you need to import it in your main App.vue file and add the router-view component.

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<script>
import Vue from 'vue';
import Router from 'vue-router';

Vue.use(Router);

export default {
  name: 'App',
  router
}
</script>
