To retrieve the code of a key, you can go to the site "". You can also make key combinations with the keys: ".ctrl", "alt", ".shift" and ".meta" (Windows key, apple, cmd, call it as you like )).Įxample of combination with these keys, if I do "control" + "a" (code: 65):Īnd they can be chained together.
For instance, we writeSome code have an alias, for the "enter" key I will do this: To fix keyup event not working with the enter key pressed on a button in Vue.js, we should replace keyup with click to listen to the click event. prevent - Prevent default handling of the event (like a page reload for a form submission).
stop - Stop the event's propagation to other handlers. įor example, if I want to run my callMethod method when I press the "1" key (code 49) in the text field I will do this: Syntactically, event modifiers are chained onto the keyup keyword as well. ), they can only be used on key-specific events (keyup, keydown.

Often when you want to do a processing following an event, you call a javascript method like event.preventDefault() for example. The callMethod function will get the "title" and display in by putting "Hello: " at the start.
