I need to hide HTML element on a page when someone press the key Printscreen so that the element not to be visible for capturing and not be copied to clipboard.

If I use the way like

document.addEventListener('keyup', (e) => {
    let charCode = e.keyCode || e.which;
    if(charCode == 44) {
        document.querySelector('my-element').style.display = 'none';
    }
});

the element is still visible at the printscreen event

Maybe there is a way how to defer the copying data to clipboard so that the element can be hidden before the copying via printscreen?

This strategy will not work. If the browser does not have focus, it will not receive key strokes and the whole screen can then be copied to the clipboard. – Lee Taylor Jul 27 '22 at 13:46
change the event listener. You hide it when the event is over. – epascarello Jul 27 '22 at 13:50

@LeeTaylor Or the fact most people use a snipping tool. – epascarello Jul 27 '22 at 13:51
@epascarello keydown doesn't help – stckvrw Jul 27 '22 at 14:19
