Lock/Freeze Web Page using jQuery

This tutorial demonstrates how to temporarily lock a webpage's interface using jQuery, creating a timed freeze effect. This is useful for developers needing to inspect dynamic content or debug scripts, or for website designers wanting to control user interaction during specific processes (like AJAX calls or popup loading).

Why Freeze a Webpage?

Freezing prevents user interaction until certain actions complete:

• After a webpage finishes loading.
• After an AJAX request completes.
• After a popup window loads.

Freezing the Webpage: A Step-by-Step Guide

1. Include jQuery: Add jquery.min.js and jquery.uilock.js to your project.

2. Implement the jQuery Code: The provided code consists of several functions:

   • load_url(url): Opens a URL in a new tab or window.
   • do_countdown(duration): Displays a countdown timer.
   • update_clock(countdown_div, new_value): Updates the countdown timer and unlocks the UI when finished.
   • format_as_time(seconds): Formats seconds into minutes and seconds.
   • view_blog_countdown(blog_url, duration): Opens a URL and starts the countdown timer.

3. Customize the jQuery UI Lock: The $.uiLock() and $.uiUnlock() functions control the visual appearance of the frozen page. Modify the CSS within these functions to adjust the overlay's style (color, opacity, etc.).

4. Integrate the HTML: The provided HTML includes a button that triggers the freeze effect.

5. Style with CSS: The CSS code styles the countdown timer's appearance.
