CGJQEdit OnKeyPress

[loufeliz]

Hello,

I would like to submit my form when user presses enter in a specific field. This should be the OnKeyPress event, but I need to only perform the action for the Enter Key. Can someone offer me a hint or an example.

Thank you.

Never mind.... I did some googling and found sometime that helped...

I wound up doing this and it seems to work fine...so far.

if ( EventParams.Values['which'] = '13' ) then
begin
btnFindCJQButtonOptionsClick(Sender,EventParams);
end;

Hi Lou

I would strongly advise you to use

JQEdit.JQEvents.OnKeyDown.Script:= 'e.which==13'

and

JQEdit.JQEvents.OnKeyDown.OnEvent

This way the server is called only when the user presses the return / enter key, and not on every keystroke, and this makes an huge difference in performance.

Thanks for the tip.. I tried but it did not work. My first use of javascript in an IW app is a fail .... I will revisit this later.

Hi Lou

I'm really sorry is not .Script is .Condition

JQEdit.JQEvents.OnKeyDown.Condition:= 'e.which==13'

In JQEdit.JQEvents.OnKeyDown, how can retrieve the key value ?
In the Event Params, i have e=[object object]

Hi Germeau

Use BrowserParams - JQEdit.JQEvents.OnKeyDown.BrowserParams

Add any value for BrowserParams[i].ServerName, this is the name you'll get in the AParams parameter of the event handled

And set BrowserParams[i].BrowserScript:= 'e.which'

The best way to check what you can bring from browser, is debugging in browser (better setting ServerController.JavaScriptOptions.Debug = True)

I have another question.
In my code, I use Events.OnKeyDown with multiple key.
For the F1 to F12 key, i want trap the keys with this event and disable F1 to F12 keys for the browser.
What is the best way for this ?
