In the digital age, protecting your web content from unauthorized access or duplication is crucial. With PageGuard.js, you can safeguard your pages effectively. This guide will walk you through how to implement PageGuard.js, understand its functions, and troubleshoot potential issues.

What Can PageGuard.js Do?

PageGuard.js prevents users from performing activities that could compromise your content, including:

• Copying text
• Printing content
• Right-clicking
• Accessing developers tools
• Running certain scripts
• Moving the mouse out of the page

This comprehensive control ensures your content remains secure, especially when JavaScript is enabled.

Getting Started with PageGuard.js

To use PageGuard.js, you need to download and install the pageguard.min.js script. Once it’s in place, you can implement its features in your web project.

Implementing AntiCopy Functionality

To block copying text from your webpage, use the following code snippet:

var anticopy_key = PageGuard.antiCopy();

If you’d like to allow users to copy content again, you can easily enable it:

PageGuard.allowCopy(anticopy_key);

Detecting Developers Tools

To enhance security further, PageGuard.js includes functionality to detect when developers tools are opened. Here’s how you can implement this:

var detectDevTools_key = PageGuard.detectDevTools(function () {
    // Your codes will run when developers tools is opening
});

To stop the detection, you can use this code:

PageGuard.stopDetectingDevTools(detectDevTools_key);

Detecting Suspect Actions

You can also detect suspicious user actions such as focus and blur, or mouse leaving the page, using:

var detectSuspect_key = PageGuard.detectSuspectActions(function() {
    // Run when it begins
}, function() {
    // Run when it ends
});

To halt the detection, simply execute:

PageGuard.stopDetectingSuspectActions(detectSuspect_key);

Disabling Dangerous Functions

To further reinforce security, you can disable functions that might allow users to circumvent protections, such as opening new windows or generating downloadable files. Use this code:

PageGuard.disableFunctions();

However, be cautious, as disabling these functions may interfere with some of your scripts.

Best Practices When Using PageGuard

To keep your security keys safe, encapsulate your JavaScript code within an immediately invoked function expression (IIFE):

(function () {
    // Your codes
})();

This practice helps prevent users from accessing your security keys directly.

Additional Resources

For supplemental protection, you can also install the anticopy.min.css for CSS-based anti-copy measures. Example implementations can be found at the following link: Example PageGuard Implementation.

Troubleshooting

If you encounter issues while implementing PageGuard.js, consider the following:

• Ensure JavaScript is enabled in your web browser, as the script requires this to function effectively.
• Check for any console errors or conflicts with other scripts, which may prevent PageGuard from working correctly.
• Since there are warnings about compatibility with Chrome 77 and other browsers, ensure your browser version is updated.
