UniHTMLMemo not firing OnKeyDown

[arilotta]

Hi all, it seems that UniHTMLMemo does not fire events OnKeyDown and OnKeyUp.

Is there any workaround ?

Thanks

Hi,

A workaround (without ShiftState), for example for "keydown":

function initialize(sender, eOpts)
{
    var me=sender;
    me.getDoc().addEventListener("keydown", function(e){
        ajaxRequest(me, 'keydown', ['key='+e.keyCode])
    });
}

Thank you Delphi Dev. It works perfectly !

Hey Delphi Dev, are you ? I see that you changed your nickname, now it's "Sherzod", but I believe it's you...

Arilotta there is a good reason for that, keep in mind that this will create a lot of network traffic as it will fire an ajax request off to the server with every keystroke...if the user types a fast 10 characters...times that with 10 users...

I would like to understand the use case of this.

what is your mean

I want to do something when i enter ENTER key

do you mean that

I need to popup a dialog when the user presses F2 that allows them to insert custom pre-configured text in the component.

Gerhard IV, your point is true, I changed the JS supplied by Sherzod in the following way, passing therefore only the F2 key via Ajax:

function initialize(sender, eOpts)
{
      var me=sender;
    me.getDoc().addEventListener("keydown", function(e){
      if (e.keyCode==113) {
        ajaxRequest(me, 'keydown', ['key='+e.keyCode])
      }
    });
}
