This JavaScript code dynamically generates and rotates QR codes from an array of URLs, creating an interactive feature for websites. It includes functionality to display QR codes and adds visual effects for enhanced user engagement, making it suitable for a module or plugin integration.

Key elements include:

  1. QR Code Generation: The generateQRCode() function generates a QR code for a URL and clears any existing code before displaying a new one, ensuring fresh content with each update.
  2. URL Rotation: The startQRCodeRotation() function switches the QR code every 5 seconds, selecting a random URL from the arr_polydev array. It ensures a different URL from the previous one for each update.
  3. Flash Animation: A flash effect is applied before updating the QR code to capture user attention. This creates a more dynamic and engaging experience.
  4. Scan Effect: CSS adds a continuous scan animation, simulating a scanning process over the QR code. This creates a visually appealing and interactive element.

This feature is ideal for websites looking to share multiple links and can be easily adapted for integration into plugins or modules on sites.
