Click a button in code in Intraweb (VCL for the Web)

Question

Lets say I have an intraweb application (written in Delphi 2010) with an iwEdit (called iweLookup) and an iwButton (iwbSearch). When enter is pressed in the iwEdit, I want the iwButton clicked.

The following code almost works, but I think I need something to re-render the page.

procedure TiwfLookupListing.iweLookupAsyncKeyDown(Sender: TObject;
  EventParams: TStringList);
begin
  if EventParams.Values['which'] = '13' then
  begin
    iwbSearchClick(Sender);
  end;
end;

However this requires a round trip to the server (which would be acceptable but not desirable). Ideally I'd like a way of doing it in Javascript - presumably in the ScriptEvents for the iwedit (but my Javascript skills are currently, um, limited)

Can anyone point me in the right direction?

Answer 1

I've pretty much solved this one, in the ScriptEvents for the button, for onKeyDown I used the following code:

if (event.which == 13) {
  IWBSEARCH_onclick(event);
  return false;
} else {
  return true;
}

But if there is a better way of doing it...
