More experienced users can easily bypass the problem of disabling the right click, and accessing most web page code itself is a basic function of the web browser and is not required at all. Right click.

Disadvantages

There are many ways to get around "no right-click script" when in reality the only effect of such a script is to annoy those who are legitimately using it in web navigation Visitors to the right-click context menu (the correct name of the menu).

Also, all the scripts I've seen that do this only block access to the context menu from the right mouse button. They didn't take into account the fact that the menu is also accessible via keyboard.

Everyone who needs to access the menu uses the 104-key keyboard to select the object on the screen they want to access the context menu (e.g. by left clicking on it) and then press the CTRL key immediately left of the context menu on the keyboard keys on computer keyboard.

Limitations

Of course, this script will not work in all web browsers (for example, Opera will ignore it - but Opera will also ignore all other Script that doesn't require right click).

This script also does not prevent visitors from accessing the page source using the View source option in their browser menu, or from saving a web page and viewing the source code of a saved copy in their favorite editor.

Finally, although you may disable access to the context menu, users can easily re-enable access by simply typing

javascript:void oncontextmenu(null)

Copy after login

into the browser's address bar.
