Cant execute document.execCommand

[Kast2k]

Dear colleagues,

I created a demo of receiving screenshot from clipboard (attached), but it works only if you are pressing Ctrl+V.

If i add this code on Button click then no result.

  UniSession.AddJS(
    'document.execCommand(''paste'');'
  );

Could you please show what am i doing wrong? How can i simulate Ctrl+V combination?

Thank You.

Calling document.execCommand("paste") is not supported by "reasonable" browsers, because of security concerns as it might enable the script to read sensitive data (like passwords) from the clipboard.

This is the compatibility matrix of document.execCommand("...") concerning clipboard events:

	"copy"	"paste"	"cut"
IE	OK	OK	n/a
Edge	OK	n/a	OK
Firefox	OK	n/a	OK
Chrome	OK	n/a	OK

What is the solution to this?
I want to click on a button to apply CTR + V,
But Clipboard does not work on the client only on the server

procedure TUniNF.UniButton1Click (Sender: TObject);
begin
Uniedit1.text: = Clipboard.AsText;
end;

Due to security reasons,the browsers are not letting you document.execCommand("paste")

There is no solution
