confident that this project is by far (with the specific time subject to the project's commits time) the **most fully-featured, open-source, and finest native JavaScript custom context menu project** on GitHub—no reliance on any frameworks required. 14 | 15 | Of course, many excellent developers may simply not have ventured into such tools; we have merely turned this idea into a practical, implementable solution. 16 | 17 | This is Version 2 of Custom-Right-Click-Menu (CRCM), rewritten based on **Web Components**. It introduces new features including custom grouping, dynamic menu item show/hide, custom menu items, theme customization, and external stylesheet loading. 18 | 19 | Compared to V1, V2 Zero Dependency, High Configurability, Easy Integration, fixes most known issues, improves extensibility, and is simplified to **single JS file deployment** — ready to use with just an import. 20 | 21 | Want to experience automated management (including automatically adding components to web pages + automatic version updates)? Experience rapid project management through [CRCMenu Manager](https://github.com/add-qwq/CRCMenu-Manager). 22 | 23 | Want to use this right-click menu across all websites? Install the [Right Click Menu - Browser Extension](https://github.com/add-qwq/CRCM-Browser-Plugin). 24 | 25 | 26 | ![Downloads](https://img.shields.io/github/downloads/add-qwq/Custom-Right-Click-Menu/total?style=flat-square&logo=github) 27 | ![GitHub license](https://img.shields.io/github/license/add-qwq/Custom-Right-Click-Menu?style=flat-square) 28 | ![GitHub stars](https://img.shields.io/github/stars/add-qwq/Custom-Right-Click-Menu) 29 | 30 | 31 | ### Project Overview 32 | - **[Online Demo (Click to Access - China Mirror Site)](https://www.rockaz.top/GitHub-Project-Demo/Custom-Right-Click-Menu/)** 33 | *Note: The server of this website is located in China, ensuring faster and more stable access for users within China. The page language is Chinese. However, for security defense purposes(To defend against a large number of automated attack IPs from outside China), all traffic from outside China has been blocked.* 34 | 35 | - **[Online Demo (Click to Access - GitHub Page Mirror Site)](https://add-qwq.github.io/Custom-Right-Click-Menu(DemoPage)/)** 36 | *Note: This website is hosted on GitHub Pages. Users within China may experience significant access delays, so it is more suitable for users outside China (users around the world).* 37 | 38 | Centered around Web Components, this project replaces the browser's native right-click menu with a flexible, highly extensible custom interface. It supports context-aware operations (text copy/paste, link/image handling, page controls) while allowing in-depth customization of styles, structure, and functionality. 39 | 40 | ### Key Features (V2 Updates) 41 | #### 1. Architecture Upgrade 42 | - Built on **Web Components** (custom elements + Shadow DOM) to achieve style and logic encapsulation and isolation 43 | - Single JS file deployment — no need to import additional CSS/HTML files 44 | - Singleton pattern design to avoid duplicate menu instances 45 | 46 | #### 2. Enhanced Customization Capabilities 47 | - **Theme Customization**: Modify menu colors, borders, blur effects, and transition speeds via CSS variables 48 | - **Custom Grouping**: Register sortable menu item groups (e.g., "General Operations", "Edit Operations") 49 | - **Dynamic Menu Items**: Add/remove menu items at runtime, and control visibility via context rules 50 | - **External Style Loading**: Support loading third-party styles (e.g., Font Awesome icon library, example CSS stylesheets) 51 | 52 | #### 3. Retained & Improved Core Features 53 | - Replaces the default browser right-click menu with a modern, animated interface 54 | - Context-aware options: 55 | - Text: Copy selected content 56 | - Input fields: Paste clipboard content 57 | - Links: Open in new tab / copy link address 58 | - Images: Open in new tab / copy image URL 59 | - Page controls: Go back, refresh, navigate to homepage 60 | - Smooth animations (scale + opacity transitions) and adaptive positioning (avoids viewport overflow) 61 | - Fallback solution for Clipboard API (supports older browsers) 62 | 63 | ### Project Structure 64 | V2 is simplified to a **single core file** (no redundant folders): 65 | - **CRCMenu.v2.js**: Core file containing Web Components definition, logic, and default configurations. 66 | Includes: 67 | - Custom element (``) 68 | - Theme management 69 | - Group/menu item registration 70 | - Context detection 71 | - Event handling (click/scroll/keydown) 72 | 73 | *Note: The legacy Tailwind CSS version (V1) is no longer maintained. V2 focuses on a lightweight, framework-free deployment experience.* 74 | 75 | *The CRCMenu Tailwind folder stores the Tailwind version of CRCMenu, which is only applicable to V1. It has been discontinued and is not related to V2* 76 | 77 | ### Quick Start 78 | 79 | #### 1.

Basic Usage (3 Steps) 87 | V2 only requires **one JS file import** — no other dependencies. 88 | 89 | ##### Step 1: Import the Core File 90 | Add the following to the `` of your HTML or before the closing `` tag: 91 | ```html 92 | 93 | 94 | ``` 95 | 96 | ##### Step 2: (Optional) Configure Theme/External Styles 97 | Modify the `createRightClickMenu()` function in `CRCMenu.v2.js` to customize the theme or load external styles (e.g., Font Awesome icon library, example CSS stylesheets): 98 | ```javascript 99 | const menu = new CustomRightClickMenu({ 100 | // Custom theme (override default CSS variables) 101 | theme: { 102 | '--menu-bg': 'rgba(255, 255, 255, 0.95)', // Menu background 103 | '--menu-border': '1px solid rgba(0, 0, 0, 0.1)', // Menu border 104 | '--menu-backdrop': 'blur(10px)', // Backdrop blur 105 | '--item-hover-bg': '#f3f4f6', // Menu item hover background 106 | '--text-color': '#6b7280', // Text color 107 | '--header-color': '#9ca3af', // Group header color 108 | '--divider-color': '#e5e7eb', // Divider color 109 | '--transition-speed': '0.1s' // Animation speed 110 | }, 111 | // Load external stylesheets (e.g., Font Awesome icons and example CSS stylesheets) 112 | externalStyles: [ 113 | 'Example.css', 114 | 'https://s4.zstatic.net/ajax/libs/font-awesome/6.4.0/css/all.min.css' 115 | ] 116 | }); 117 | ``` 118 | 119 | ##### Step 3: Auto-Initialization 120 | The menu automatically initializes via the built-in `createRightClickMenu()` function when the DOM is fully loaded. Right-click anywhere on the page to trigger the custom menu. 121 | 122 | ### Advanced Customization 123 | V2’s core advantage lies in its high extensibility. Below are common customization scenarios with code examples. 124 | 125 | #### 1. Register Custom Groups 126 | Groups are used to organize menu items and support sorting via the `order` parameter (smaller values = higher priority): 127 | ```javascript 128 | // Inside the createRightClickMenu() function 129 | menu.registerGroup({ 130 | id: 'other', // Unique group ID 131 | name: 'Other Operations', // Group header text 132 | order: 50 // Display order 133 | }); 134 | ``` 135 | 136 | #### 2. Add Custom Menu Items 137 | Register new menu items, bind callback functions, and control visibility via the `context` function: 138 | 139 | ```javascript 140 | // Inside the createRightClickMenu() function 141 | // Example: Add a "Test" menu item (always visible) 142 | menu.registerMenuItem({ 143 | id: 'test', // Unique menu item ID 144 | label: 'Test', // Menu item text 145 | icon: 'fa-question', // Icon (from Font Awesome) 146 | callback: testAction, // Bound callback function 147 | context: () => true, // Always visible (context function returns true) 148 | group: 'other' // Associate with the "other" group 149 | }); 150 | 151 | // Corresponding callback function (defined separately) 152 | const testAction = (ctx) => { 153 | alert('This is a test'); 154 | }; 155 | ``` 156 | 157 | #### 3. Unregister Groups/Menu Items 158 | Remove unwanted groups or menu items at runtime: 159 | ```javascript 160 | // Unregister a group (also removes all its menu items) 161 | menu.unregisterGroup('other'); 162 | 163 | // Unregister a single menu item 164 | menu.unregisterMenuItem('test'); 165 | ``` 166 | 167 | #### 4. Mount to a Specific Element 168 | By default, the menu is mounted to `window` (triggers on all right-clicks). You can mount it to a specific element to limit its scope: 169 | ```javascript 170 | // Mount only to the
element 171 | const content = document.getElementById('content'); 172 | menu.mount(content); 173 | 174 | // Unmount later if needed 175 | menu.unmount(); 176 | ``` 177 | 178 | #### 5. Dynamically Update the Theme 179 | Modify the theme after initialization: 180 | ```javascript 181 | // Dynamically modify the style within the page (without changing the project source code) 182 | document.addEventListener('DOMContentLoaded', function() { 183 | window.globalMenu = createRightClickMenu(); 184 | window.globalMenu.setTheme({ 185 | '--menu-bg': 'rgba(255, 255, 255, 0.1)', 186 | '--menu-border': '1px solid rgba(255, 255, 255, 0.05)', 187 | '--menu-backdrop': 'blur(10px)', 188 | '--transition-speed': '0.1s', 189 | '--item-hover-bg': 'rgba(255, 255, 255, 0.3)', 190 | '--text-color': 'white', 191 | '--header-color': 'white', 192 | '--divider-color': '#e5e7eb' 193 | }); 194 | }); 195 | ``` 196 | 197 | ### Implementation Principle 198 | #### 1. Web Components Foundation 199 | - **Custom Element**: `` is registered via `customElements.define()`, enabling reuse across projects. 200 | - **Shadow DOM**: Isolates menu styles from the parent page (avoids CSS conflicts). 201 | - **Singleton Pattern**: Ensures only one menu instance exists (prevents duplicates). 202 | 203 | #### 2. Context Detection Logic 204 | The menu uses JavaScript to detect the right-click context in real time: 205 | - **Text Selection**: `window.getSelection().toString()` 206 | - **Link Detection**: `closest('a')` or parsing URLs from `onclick` attributes 207 | - **Image Detection**: `closest('img')` or parsing `background-image` styles 208 | - **Input Focus Detection**: `document.activeElement` (detects ``, `
