Javascript Copy to clipboard functionality

[kelemenattila]

I need to copy custom formatted data in javascript to clipboard using ChromiumBrowser.
I'm adding the text to the clipboard with the following JS code:

navigator.clipboard.writeText(formattedText);

In case of ChromiumBrowser the text doesn't appear in clipboard. In case of other browsers (Chrome, Brave, Edge) works.
I got a workaround with creating a ghost element copy content with document.execCommand('copy'), works but 1/10 doesn't only if I debug the JS code step by step. By the way execCommand is obsolete :(

I attached the full workarround code but I prefer to use somehow the navigator to copy to clipboard if it is possible.
Thanks :)

const element = document.createElement('textarea');
element.value = formattedText;
document.body.appendChild(element);
element.select();
document.execCommand('copy');
document.body.removeChild(element);

By default permission to cliipboard should be disabled. You can grant permissions programmatically.

• CefSharp/CefSharp/IWebBrowser.cs

  Line 140 in 800cbcf

  IPermissionHandler PermissionHandler { get; set; }

• CefSharp/CefSharp.Example/Handlers/ExamplePermissionHandler.cs

  Line 13 in 800cbcf

  public class ExamplePermissionHandler : PermissionHandler

chromiumWebBrowser.PermissionHandler = new MyPermissionHandler();`
