#USING PROMISES WITH KEYUP FOR FORMS CODE#

But this is not triggered when pressing enter.

A form can have the focus only if it has. Hi Yasser, Thanks for the response, I should have been a little clearer, what I really need to do is work out when I am in the event if there are any other keystrokes in the keyboard buffer when the event is triggered (after the keystroke that trigged the event in the first place), if so cancel this iteration of the event to allow it to be triggered again by the next keystroke in the buffer. In NG2, declaratively: you can use (keyup.enter) for registering press-enter events.Like this: In NG2, reactive forms: I can use the valueChanges observable to listen for changes.

In this chapter, we cover all of them in detail. The Promise class comprises five static methods. If you call. The form or control with the focus receives all keystrokes. As we have already stated, promises in JavaScript represent the eventual completion or failure of an asynchronous operation, as well as its resulting value. First of all, none of the forms are children here, and your main form is not a parent of your other form. The KeyDown and KeyPress events alternate repeatedly until the user releases the key, at which time the KeyUp event occurs.

I'm a Promise newbie and I am trying to convert some existing code (which is quite simple) to work with promises. The KeyDown event occurs when the user presses a key on a running form while that form or a control on it has the focus. EDIT: tried to clarify the question and shorten it - I'd put in some code to show I had tried to solve this, but I think it only confused things.
