摘要
Vue.js的優點有很多,但是其使用門檻對於只學習過普通的專案的同學來說,還是比較有挑戰性的,如果你真的想把Vue學的很溜,真的需要一個非常系統的學習才能運用起來。因為學習Vue你不僅僅是學習他的語法、API和一些開發的規範,你還要學習構建工具的使用、除錯、打包等等,有些人連最基本的開發環境都還沒能順利搭建起來。
如果你不想使用Vue強大的生態和工具,只想在html頁面中使用Vue也是可以的,因為Vue也有一個全域性的生產環境cdn(vue.global.prod.min.js),你可以使用這個cdn來使用Vue構建比較小型的專案。
專案介紹
寫這篇文章的原因是我使用了Vue3的組合式Api實現了一個非常簡單的單頁,具體資訊如下:
專案:圍繞廣東省3+證書招生考試資訊為資料,開發一個招生院校、招生專業資訊查詢和展示頁面。
資料:廣東3+證書招生院校目錄、招生專業目錄。
專案截圖:
程式碼結構:
上程式碼
index.html
程式碼中引入了 vue.global.prod.min.js
用於使用Vue的API,引入了 vue-router.js
實現路由功能,引入了 axios.min.js
實現請求介面獲取資料。
在app節點下透過 <router-view></router-view>
渲染對應路由的內容。
關鍵的程式碼都在 app.js
中使用Vue3的組合式API實現資料請求和資料響應式渲染。所以透過模組的方式引入了 app.js

也是比較簡單的,構建元件程式碼,然後將元件建立到路由當中渲染到app節點。
const { createApp, ref } = Vue;
const { createRouter, createWebHashHistory, useRouter, useRoute } = VueRouter;
