[suleymankose]

Kullandığım version Trial 1559

function mousemove(sender, x, y, eOpts)
{
  ajaxRequest(sender, 'MouseMoveEvent', [ 'param0='+x, 'param1='+y]);
}

 

procedure TMainForm.UniPanel2AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = 'MouseMoveEvent' then
  begin
    UniLabel1.Caption := Params.Values['x'];
    UniLabel2.Caption := Params.Values['y'];
  end;
end;
 

 

x ve y Bilgisi boş geliyor
