Copy Text to Clipboard in Delphi TMS Web Core Website

Question

The VCL/FMX way of copying text to the clipboard doesn't work in TMS Web Core.

How can I copy text (Strings) to the clipboard in a Delphi TMS Web Core Website?

Answer 1

There are multiple ways to copy text to the clipboard in TMS Web Core:

---

1. TWebClipboard (Non-Visual Component)

Add a TWebClipboard component to your form and then you can copy text to it by running:

WebClipboard.CopyToClipboard('Your String to Copy to Clipboard');

---

2. TWebClipboard Custom Method

You can make your own procedure that creates and uses the TWebClipboard component from the WEBLib.Clipboard unit:

procedure CopyTextToClipboard(aText: String);
var
  WebClipboard: TWebClipboard;
begin
  WebClipboard := TWebClipboard.Create(self);
  try
    WebClipboard.CopyToClipboard(aText);
  finally
    WebClipboard.Free;
  end;
end;

3. JavaScript function

You can make a Delphi function that uses JavaScript to copy text to the clipboard:

procedure CopyTextToClipboard(aText: String);
begin
  asm
    window.navigator.clipboard.writeText(aText);
  end;
end;
