Help me - Chromium1.Browser.MainFrame.ExecuteJavaScript

[Wagner Campanari]

I'm trying to insert values ​​inside this input, with the code below:

Chromium1.Browser.MainFrame.ExecuteJavaScript ('document.getElementById ("FormRow-BUY-quantity"). Value = "100";', 'about: blank', 0);

 

I am using chromium cef4 https://www.briskbard.com/index.php?lang=en&pageid=cef in rad studio 10.2, the code sends the value to the input, but after a few milliseconds the value disappears from the input, as if it had not been rendered in the input.

More testing in another way I was able to send the value as per the code below:

procedure TMiniBrowserFrm.Button1Click(Sender: TObject);

var

  event: TCefKeyEvent;

begin

  FillChar(event, SizeOf(TCefKeyEvent), 0);

  event.kind := KEYEVENT_KEYDOWN;

  event.windows_key_code := ord('1') ;

   Chromium1.Browser.Host.Browser.MainFrame.Browser.Host.SendKeyEvent(@event);

  event.windows_key_code := ord('0') ;

  Chromium1.Browser.Host.Browser.MainFrame.Browser.Host.SendKeyEvent(@event);

  FillChar(event, SizeOf(TCefKeyEvent), 0);

  event.kind := KEYEVENT_CHAR;

  event.windows_key_code := ord('1');

   Chromium1.Browser.Host.Browser.MainFrame.Browser.Host.SendKeyEvent(@event);

  event.windows_key_code := ord('0') ;

  Chromium1.Browser.Host.Browser.MainFrame.Browser.Host.SendKeyEvent(@event);

  FillChar(event, SizeOf(TCefKeyEvent), 0);

  event.kind := KEYEVENT_KEYUP;

  event.windows_key_code := ord('1');

   Chromium1.Browser.Host.Browser.MainFrame.Browser.Host.SendKeyEvent(@event);

  event.windows_key_code := ord('0') ;

  Chromium1.Browser.Host.Browser.MainFrame.Browser.Host.SendKeyEvent(@event);

end;

I would like to know how I can fix the problem using javaScripit what should I do to make it work?

Chromium1.Browser.MainFrame.ExecuteJavaScript ('document.getElementById ("FormRow-BUY-quantity"). Value = "100";', 'about: blank', 0);

 

<input class = "sc-1c2873k-1 gszTkZ" type = "number" id = "FormRow-BUY-quantity" name = "quantity" step = "0.000001" min = "0.000001" value = "">
