daisyUI 常用组件速查（按使用频率排序） daisyUI 常用组件速查（按使用频率排序）基于：daisyUI🔥 第一梯队（高频核心组件）👉 后台 / 表单 / 页面核心1️⃣ Button（按钮）<button class="btn">默认按钮</button> <button class="btn btn-primary">主要按钮</button> <button class="btn btn-success">成功</button> <button class="btn btn-error">错误</button>常用组合<button class="btn btn-primary btn-sm">小按钮</button> <button class="btn btn-outline">描边按钮</button> <button class="btn btn-ghost">幽灵按钮</button> <button class="btn loading">加载中</button>2️⃣ Input（输入框）<input class="input input-bordered" placeholder="请输入内容">常用组合<input class="input input-primary" placeholder="主要输入框"> <input class="input input-error" placeholder="错误状态"> <input class="input input-bordered w-full" placeholder="全宽">3️⃣ Select（下拉框）<select class="select select-bordered"> <option>选项1</option> <option>选项2</option> </select>4️⃣ Textarea（多行输入）<textarea class="textarea textarea-bordered" placeholder="输入内容"></textarea>5️⃣ Checkbox / Radio（选择）<input type="checkbox" class="checkbox"> <input type="radio" class="radio">6️⃣ Card（卡片）<div class="card bg-base-100 shadow"> <div class="card-body"> <h2 class="card-title">标题</h2> <p>内容</p> <button class="btn btn-primary">操作</button> </div> </div>7️⃣ Alert（提示）<div class="alert alert-success">成功提示</div> <div class="alert alert-error">错误提示</div>8️⃣ Badge（标签）<span class="badge">默认</span> <span class="badge badge-primary">主要</span>9️⃣ Table（表格）<table class="table"> <thead> <tr><th>姓名</th><th>年龄</th></tr> </thead> <tbody> <tr><td>张三</td><td>18</td></tr> </tbody> </table>🔟 Modal（弹窗）<dialog id="my_modal" class="modal"> <div class="modal-box"> <h3 class="font-bold text-lg">标题</h3> <p>内容</p> <div class="modal-action"> <form method="dialog"> <button class="btn">关闭</button> </form> </div> </div> </dialog> <button class="btn" onclick="my_modal.showModal()">打开弹窗</button>⚡ 第二梯队（常用辅助组件）1️⃣ Navbar（导航栏）<div class="navbar bg-base-100"> <div class="flex-1">Logo</div> <div class="flex-none"> <button class="btn">登录</button> </div> </div>2️⃣ Drawer（侧边栏）<div class="drawer"> <input id="drawer-toggle" type="checkbox" class="drawer-toggle"> <div class="drawer-content"> <label for="drawer-toggle" class="btn btn-primary">打开菜单</label> </div> <div class="drawer-side"> <ul class="menu p-4 w-80 bg-base-200"> <li><a>首页</a></li> <li><a>用户</a></li> </ul> </div> </div>3️⃣ Menu（菜单）<ul class="menu bg-base-200 w-56"> <li><a>首页</a></li> <li><a>用户</a></li> </ul>4️⃣ Dropdown（下拉菜单）<div class="dropdown"> <label tabindex="0" class="btn">菜单</label> <ul tabindex="0" class="dropdown-content menu p-2 bg-base-100 shadow w-52"> <li><a>选项1</a></li> <li><a>选项2</a></li> </ul> </div>5️⃣ Tabs（标签页）<div role="tablist" class="tabs tabs-boxed"> <a role="tab" class="tab tab-active">Tab1</a> <a role="tab" class="tab">Tab2</a> </div>6️⃣ Progress（进度条）<progress class="progress progress-primary w-56" value="50" max="100"></progress>7️⃣ Loading（加载动画）<span class="loading loading-spinner"></span>8️⃣ Tooltip（提示）<button class="btn" data-tip="提示内容">悬停</button>9️⃣ Divider（分割线）<div class="divider">分割</div>💀 最实用总结核心组件： button / input / table / modal / card 后台结构： drawer / menu / navbar 增强组件： alert / badge / loading / tooltip🚀 使用建议不需要死记组件多复制官方示例多组合 class多做页面练习👉 实战优先，记忆其次📌 推荐练习登录页（input + button）表格列表（table）弹窗操作（modal）后台布局（drawer + menu）👉 做完这些基本就能上手项目下面是 daisyui+alpinejs的示例<html lang="en" data-theme="bumblebee-custom"> <head>

Alpine.js 第四阶段学习笔记（组件化与复用） Alpine.js 第四阶段学习笔记（组件化与复用）基于：Alpine.js🧠 第四阶段核心组件化 + 逻辑复用👉 从“写页面”升级为“写组件”1️⃣ Alpine.data()（组件定义）👉 作用将一段逻辑封装为可复用组件✅ 完整示例<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <script src="https://unpkg.com/alpinejs" defer></script> </head> <body> <script> document.addEventListener('alpine:init', () => { Alpine.data('counter', () => ({ count: 0, inc() { this.count++ } })) }) </script> <div x-data="counter"> <button @click="inc()">+1</button> <span x-text="count"></span> </div> <div x-data="counter"> <button @click="inc()">+1</button> <span x-text="count"></span> </div> </body> </html>💡 特点每个组件实例独立数据互不影响可重复使用2️⃣ 组件参数（可配置组件）👉 作用像函数一样给组件传参数✅ 示例<script> document.addEventListener('alpine:init', () => { Alpine.data('counter', (init = 0) => ({ count: init, inc() { this.count++ } })) }) </script> <div x-data="counter(5)"> <button @click="inc()">+1</button> <span x-text="count"></span> </div>💡 理解counter(5)3️⃣ 逻辑拆分（函数封装）👉 作用避免 HTML 中逻辑过多✅ 示例<script> function userForm() { return { name: '', submit() { alert("提交：" + this.name) } } } </script> <div x-data="userForm()"> <input x-model="name"> <button @click="submit()">提交</button> </div>💡 优势逻辑清晰易维护易扩展4️⃣ 多组件独立👉 作用页面多个模块互不干扰✅ 示例<div x-data=""> <span x-text="msg"></span> </div> <div x-data=""> <span x-text="msg"></span> </div>💡 特点每个组件独立作用域不会污染其他组件5️⃣ 全局状态（Alpine.store）👉 作用多个组件共享数据✅ 示例<script> document.addEventListener('alpine:init', () => { Alpine.store('user', { name: '张三' }) }) </script> <div> <span x-text="$store.user.name"></span> </div> <div> <input x-model="$store.user.name"> </div>💡 类似Vuex / Pinia（但更轻量）💀 第四阶段核心总结Alpine.data() → 定义组件 参数传递 → 提高复用 函数封装 → 拆逻辑 多组件 → 页面结构 store → 全局状态🔥 能力提升阶段能力第一阶段数据绑定第二阶段控制DOM第三阶段响应式逻辑第四阶段组件复用🧠 本质变化之前：写页面 现在：写组件🚀 实战建议练习一个小项目：👉 用户管理页面输入用户名（x-model）点击添加（x-on）列表展示（x-for）删除数据（事件处理）👉 用 Alpine.data 封装📌 学习建议少看文档，多写代码每个组件自己改一遍尝试复用组件👉 不动手 = 学不会

Alpine.js 第三阶段学习笔记（对比 jQuery） Alpine.js 第三阶段学习笔记（对比 jQuery）基于：Alpine.jsjQuery1️⃣ x-transition（动画）👉 作用给 x-show / x-if 增加过渡动画✅ Alpine 完整示例<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <script src="https://unpkg.com/alpinejs" defer></script> </head> <body> <div x-data=""> <button @click="open = !open">切换</button> <div x-show="open" x-transition style="padding:20px;background:#4ade80;"> 动画内容 </div> </div> </body> </html>🔁 jQuery 对比<script src="https://cdn.jsdelivr.net/npm/jquery/dist/jquery.min.js"></script> <button id="btn">切换</button> <div id="box" style="display:none;">动画内容</div> <script> $("#btn").click(function() { $("#box").fadeToggle(); }); </script>2️⃣ $refs（操作 DOM）👉 作用直接获取 DOM 元素（替代 querySelector / $）✅ Alpine 示例<div x-data> <input x-ref="input"> <button @click="$refs.input.focus()">聚焦</button> </div>🔁 jQuery 对比<input id="input"> <button id="btn">聚焦</button> <script> $("#btn").click(function() { $("#input").focus(); }); </script>3️⃣ $watch（监听数据变化）👉 作用监听变量变化，自动执行逻辑✅ Alpine 示例<div x-data="" x-init="$watch('count', val => alert(val))"> <button @click="count++">+1</button> </div>🔁 jQuery 对比（本质不支持）let count = 0; $("#btn").click(function() { count++; alert(count); });👉 jQuery 无法真正“监听变量”4️⃣ x-effect（自动副作用）👉 作用数据变化时自动执行代码✅ Alpine 示例<div x-data=""> <div x-effect="document.title = 'Count: ' + count"></div> <button @click="count++">+1</button> </div>🔁 原生 / jQuery 对比let count = 0; function update() { document.title = "Count: " + count; } $("#btn").click(function() { count++; update(); });👉 必须手动调用5️⃣ x-init（初始化）👉 作用页面加载时执行逻辑✅ Alpine 示例<div x-data="" x-init="msg = '页面加载完成'"> <span x-text="msg"></span> </div>🔁 jQuery 对比$(document).ready(function() { $("#text").text("页面加载完成"); });💀 第三阶段核心总结x-transition → 动画 $refs → 操作DOM $watch → 监听数据 x-effect → 自动执行逻辑 x-init → 初始化🔥 本质区别方式思维jQuery操作 DOMAlpine操作 数据🧠 核心理解传统写法： 点击 → 操作 DOM Alpine： 修改数据 → DOM 自动更新🚀 学习建议建议你做一个练习：点击按钮打开弹窗（x-show）带动画（x-transition）输入框自动聚焦（$refs）输入变化自动打印（$watch）👉 做完这个，第三阶段就通了

wsl2无法使用,切换成wsl1能用,提示开启虚拟化 问题 wsl1能运行,wsl2提示需要开启虚拟化1.运行以管理员身份运行Windows Powershell (管理员)运行bcdedit /set hypervisorlaunchtype auto2.wsl查看版本和升级wsl2wsl -l -v wsl --set-version 分发版名称 版本号 -- 例如，将Ubuntu18.04 设置为WSL2的命令为 wsl --set-version Ubuntu-18.04 2 -- 然后设置成自动 bcdedit /set hypervisorlaunchtype auto 3. VMware15.5.5+的版本支持Hyper-V了,以前的不支持和wsl2一起用 4. 本地计算机策略 > 计算机配置 > 管理模板>系统 > Device Guard进行设置。 打开 基于虚拟化的安全设置为“已开启”或者“未设置”。  5.不行就关闭启用或关闭windows的功能,然后卸载wsl和linux重新试
