How to Add a Web Page to Favorites Using JavaScript

Adding a webpage to a browser’s favorites directly through JavaScript isn’t widely supported due to security and privacy restrictions. However, you can use some alternative methods to guide users on how to add a page to their favorites manually.

Method 1: Using `window.external.AddFavorite` (Internet Explorer Only)

For Internet Explorer, you can use the window.external.AddFavorite() method. Here’s how it works:

123456789101112131415

function addToFavorites(url, title) {
  if (window.sidebar) {
    // Firefox
    window.sidebar.addPanel(title, url, '');
  } else if (window.external && 'AddFavorite' in window.external) {
    // IE
    window.external.AddFavorite(url, title);
  } else {
    // Other browsers
    alert('Press Ctrl+D to add this page to your favorites.');
  }
}

// Usage
addToFavorites('https://example.com', 'Example Page');

Method 2: Prompt Users to Add to Favorites Manually

Since most modern browsers don’t allow direct bookmarking, you can display a message prompting users to add the page to favorites manually:

123456

function showAddToFavoritesPrompt() {
  alert('Press Ctrl+D to add this page to your favorites.');
}

// Usage
showAddToFavoritesPrompt();

Method 3: Use a Bookmark Link

Create a draggable link that users can add to their bookmarks bar by dragging and dropping:

html

123

<a href="https://example.com" title="Example Page" draggable="true"
  >Add this page to your favorites</a
>

Method 4: Use Progressive Web App (PWA) Features

Although there is no direct API to add favorites, you can enhance the experience by creating a PWA. The Web App Manifest allows users to save your site to their device’s home screen.

{
  "name": "Example App",
  "short_name": "Example",
  "start_url": "/",
  "display": "standalone",
  "background_color": "#fff",
  "theme_color": "#000",
  "icons": [
    {
      "src": "icon.png",
      "sizes": "192x192",
      "type": "image/png"
    }
  ]
}

Summary

JavaScript cannot directly add a webpage to favorites in most modern browsers, but these workarounds—manual prompts, draggable links, and PWA features—can help guide users to save your page to favorites, improving the user experience.
