I want to restrict typing in a text box but I need to paste anything inside that textbox in Angular
You have to stop the event propagation if the combination pressed is different than the one you choose.
You can do it like this:
public onInput(event: KeyboardEvent) {
//if is pressed a different key than c or v, or the ctrl key isn't pressed stop event
if (!event.ctrlKey || (event.key.toLowerCase() !== 'c' && event.key.toLowerCase() !== 'v')) {
event.stopImmediatePropagation();
event.stopPropagation();
event.preventDefault();
}
// else execute the default event behaviour
}<input type="text" (keydown)="onInput($event)">Hope it helps. ^^
P.S.: You have to use the event keydown for this to work.
