Script Functionality

Preventing Loss of Focus

The script includes functionality to keep the window always in focus. This is achieved by:

• Overriding window.onblur to null to prevent loss of focus.
• Setting a window.blurred flag to false.
• Overriding document.hasFocus to always return true.
• Overriding various properties (hidden, mozHidden, msHidden, webkitHidden) to always report the document as visible.
• Overriding document.visibilityState and document.webkitVisibilityState to return "visible".
• Setting document.onvisibilitychange to undefined.

Event Handling

The script prevents specific events from triggering their default behavior, specifically for blur, mouseleave, and mouseout events, except when they are on input, anchor, or span elements.

Video Playback Functionality

• updateVideoProgress Function: Checks if the video is playing every 30 seconds. If not, it starts playing the video.
• setupVideoCheck Function: Sets an interval to check video playback status.
• isVideoPlaying Function: Checks if the video element (with id 'realvideo_html5_api') is playing.
• startPlayingVideo Function: Starts playing the video if it is found and is not currently playing.

Initialization

• The script adds an event listener to the window's load event to start checking the video playback status.

Usage

Notes
