Enter button firing twice

JavaScript

Why is the enter button firing this function twice? Tab onto the element and hit enter.

I suppose the default action of selecting an element with the keyboard is to trigger a click event on that element… so you can actually call event.preventDefault() inside the event.type === 'keydown' conditional to prevent the click event from getting dispatched. Personally I always found it quite nice not having to implement all that separately though. :-) So the simplest solution would be to remove the keydown handler altogether.

So basically the click event is enough. Just curious why it was doing that, but it seems it’s on purpose. Thanks! Colleague asked me and I couldn’t figure out why this was behaving like this. Good to know we aren’t going crazy! Appreciate the help.
