一、前言

2021 年第一个周末，祝各位读者敌人安全顺利。
以前读过一句话：“当你穿过暴风雨的时候，你就不是原来那个人了。”
但他没有说，咱们要如何穿过暴风雨。
2020 刚开始的时候，我曾感觉冬天无比漫长，仿佛没有止境。到了六月的时候，才察觉工夫过得比设想更快。而当初，2020 年曾经过来了，想来总感觉有些恍惚，那些工夫那些岁月到底是怎么流逝的呢？那么，咱们到底是如何穿过暴风雨的呢？
只有在这么一个时刻，能力明确，让咱们穿梭暴风雨的，不过是每一天的平庸生存。
当咱们的生存日夜旋转不休，眼前的现象朦胧一片时，咱们惟一能做的只是致力看清了脚底下的路，并且决定一步步缓缓前行。
我想是这样的，从没有欲速不达的事，只有每一天致力前行。
直到某天乌云散去，回过头看，能力晓得本人走了多远。
因为人生没有白走的路，每一步都算数。

周末用 Vue.js 和 Semantic-UI 做了一个简略的欲望清单，记录当前想和喜爱的人一起做的事，疲乏的生存里总要有些温顺的幻想吧。

二、Vue.js 介绍

官网文档传送门：https://cn.vuejs.org/v2/guide/installation.html

Vue (读音 /vjuː/，相似于 view) 是一套用于构建用户界面的渐进式框架。与其它大型框架不同的是，Vue 被设计为能够自底向上逐层利用。Vue 的外围库只关注视图层，不仅易于上手，还便于与第三方库或既有我的项目整合。另一方面，当与现代化的工具链以及各种反对类库联合应用时，Vue 也齐全可能为简单的单页利用提供驱动。

仿照官网案例的我的项目，次要为了相熟 Vue.js 的根本用法，通过这个案例能排汇到根本的 Vue.js 操作

重构此我的项目能够学到以下知识点：

  • 根本的数据绑定语法
  • 计算属性
  • Class 绑定
  • 条件渲染
  • 列表渲染
  • 办法与事件绑定
  • 表单空间绑定
  • 自定义指令

额定还能学习到 LocalStorage 的简略用法，能够说通过具体学习此例子能够实现 Vue.js 最根本的入门操作，齐全相熟不太容易，次要是感触下 Vue.js 的弱小和根本的应用，那么好的框架当然是越学越香，更多具体应用能够参考官网文档。

三、Semantic UI 介绍

官网文档传送门：https://zijieke.com/semantic-ui/introduction/getting-started.php

在 HTML 中蕴含 (Include in Your HTML)：
运行 gulp 构建工具将会在你的我的项目中编译出 CSS 和 Javascript 文件。把编译出的文件和最新的 jQuery 一起蕴含到 HTML 中就能够应用 Semantic UI 了，更多具体应用能够参考官网文档。

援用资源

运行成果如下：

应用 Vue.js 和 Semantic-UI 做了一个简略的欲望清单，实现了页面和用户的交互，在输入框中写入想和喜爱的人一起做的事，而后按 Enter 键或者点击左边的“+”，即可将数据增加进去，下方 3 Left 示意还有 3 个欲望未实现，点击 All 查看所有的欲望清单，点击 Wait 查看未实现的欲望，点击 Completed 查看已实现的欲望，谬误增加进去的内容能够先选定，而后应用 Clear 革除掉再从新增加，或者鼠标悬停在那一条内容上，呈现❌而后点击删除再从新增加，界面简洁好看，使用方便。

也能够应用 selenium 来关上本地 html 文件自动化增加
