我们可以直观地看到App.vue文件以及index.css文件的代码行数都有400多行。


在复杂应用中，该写法缺乏组件化，页面内容和样式难以管理，不利于维护和扩展。

二、现代的 Vue.js 组件化写法

利用 Vue.js 的组件化机制，将该页面分为如下七大组件：

页面开发思路：

1. 分析页面，按模块拆分组件、搭架子 (局部或全局注册)
2. 根据设计图，编写组件 html 结构 css 样式
3. 拆分封装通用小组件 (局部或全局注册)， 通过 js 动态渲染，实现功能

运行结果：

该写法具有以下优点：

1. 组件化：每个组件有自己的 HTML、CSS 和 JavaScript 逻辑，提高了代码的复用性和组织性。
2. 数据驱动：可以轻松管理组件的状态和数据，提供更好的交互体验。
3. 维护性：组件化使得维护和扩展变得更加容易，可以将复杂的页面拆分为多个可重用的组件。
