How to detect when the user presses the CTRL+V (Paste) keyboard shortcut?

Question

I tried using document.body.onpaste but its never called. How would I register for the Paste event?

Answer 1

Hi,

I would like to point out that Ctrl+C is used to copy instead of to paste. So please handle the oncopy event.

In addition, to add an event handler in JavaScript, you can invoke addEventListener like this:

            document.body.addEventListener("copy", oncopy);
            document.body.addEventListener("paste", onpaste);

Best Regards,

Ming Xu.

Answer 2

I meant the Paste CRTL+V shortcut :) Have you tried this yourself? It did not work with document.body.onpaste... which should be the same as the addEventListener approach?

Answer 3

Phil,

You can trap the key down and look for the ctrl+C or V combination:

         args.setPromise(WinJS.UI.processAll());

         document.body.addEventListener("keydown", onkeydown);

 function onkeydown(event) {
        if (event.ctrlKey === true && event.key==="c") {
            var str = "ho";
        }
    }

Answer 4

so the onpaste / addEventHandler("paste") for the document.body is broken at the moment?

Answer 5

No it is not broken.

You cannot "Paste" into the body... only input elements.
