where to call windows.onbeforeunload

To handle the window.onbeforeunload event in an MVC application without it triggering on every view change, you can use a combination of JavaScript and conditional logic to ensure it only runs when the user is actually closing the tab or browser. Here’s a suggested approach:

Add a flag to track navigation within the application:
Use JavaScript to set a flag when navigating within the application.
Reset the flag when the page is fully loaded.
Modify the window.onbeforeunload event:
Check the flag to determine if the event should be triggered.




    My MVC Application
    


    @RenderBody()

Ensure internal navigation is tracked correctly:
The above script sets isInternalNavigation to true when an internal link is clicked.
It resets the flag to false when the page is fully loaded.
This way, the window.onbeforeunload event will only trigger when the user is actually closing the tab or browser, not when navigating between views within your application.
