All this is written in the Aurelia documentation. In my experience, keydown is the only keyboard event worth using, keypress can be ignored entirely, and keyup is well suited for getting dusty on the shelf. We had to return true in order to propagate the event. So, if we need to handle those keys, it's better to use either keydownor keyupevent. The keypressignores keys such as delete, arrows, page up, page down, home, end, ctrl, alt, shift, esc, etc. Everything we were missing was that Aurelia calls event.preventDefault() and that The keydownand keyupevents are often used to handle the physical keys, while the keypressevent is used to handle characters which are being typed. This was quite frustrating because what could possibly go wrong in 4 lines of code? Especially because we are using event binding already multiple times throughout the application.īut sometimes you just have to “read the fucking manual”.
We googled a lot and couldn’t find any helpful information on keyboard event binding.
KEYPRESS VS KEYUP FULL
See the full example of keypress event binding here RTFM So assuming the following code keyboard event binding: handleKeypress ( $event ) delegate, right? That’s true except a little exception regarding keyboard events on an input field. In Aurelia, you can bind on nearly every Event just omit the “on” prefix and append a. Probably me in a year :) Keypress And Keydown Event Binding keyup: Fires when the user releases a key, after the default action of that key has been performed. It repeats while the user keeps the key depressed. keypress: Fires when an actual character is being inserted in, for instance, a text input. keypress: Fires when an actual character is being inserted in, for instance, a text input.
The main reason to write this blog post is, to provide a better search result in case somebody runs into the same problem. keydown: Fires when the user depresses a key.
KEYPRESS VS KEYUP HOW TO
It’s trivial when you know how to do it, but if you don’t, you have to find this specific piece of documentation that tells you about the right syntax. We had such a case last week and had problems with a not working keydown and keypress binding. But still, it can happen that you and even none of your colleagues can see the trees in the forest. Sometimes all you need to know is right in front of you.
