摘要

Vue.js的优点有很多,但是其使用门槛对于只学习过普通的项目的同学来说,还是比较有挑战性的,如果你真的想把Vue学的很溜,真的需要一个非常系统的学习才能运用起来。因为学习Vue你不仅仅是学习他的语法、API和一些开发的规范,你还要学习构建工具的使用、调试、打包等等,有些人连最基本的开发环境都还没能顺利搭建起来。

如果你不想使用Vue强大的生态和工具,只想在html页面中使用Vue也是可以的,因为Vue也有一个全局的生产环境cdn(vue.global.prod.min.js),你可以使用这个cdn来使用Vue构建比较小型的项目。

项目介绍

写这篇文章的原因是我使用了Vue3的组合式Api实现了一个非常简单的单页,具体信息如下:

项目:围绕广东省3+证书招生考试信息为数据,开发一个招生院校、招生专业信息查询和展示页面。

数据:广东3+证书招生院校目录、招生专业目录。

项目截图:

代码结构:

上代码

index.html

代码中引入了 vue.global.prod.min.js 用于使用Vue的API,引入了 vue-router.js 实现路由功能,引入了 axios.min.js 实现请求接口获取数据。

在app节点下通过 <router-view></router-view> 渲染对应路由的内容。

关键的代码都在 app.js 中使用Vue3的组合式API实现数据请求和数据响应式渲染。所以通过模块的方式引入了 app.js
