ngKeyup, ngKeydown and ngKeypress

[Dawid Anonim]

Hello

why ngKeyup, ngKeydown and ngKeypress have exactly the same documentation but they don't work the same? example:

<div>
<textarea ng-keydown="keyEvent = $event"></textarea>
</div>
<div>
<strong>Key code:</strong> {{ keyEvent.keyCode }} <br>
</div>

if you put ng-keydown and ng-keyup it works if u put ng-keypress it dosen't work
anyone know why?

AngularJS v.1.5.7

I don't think this is an Angular issue. KeyUp and KeyDown events are different from KeyPress events. KeyUp/Down give you key codes while KeyPress gives you character codes - sometimes these are the same, sometimes they are not. The way in which the different browser have implemented the events differs as well. Some libraries, like jQuery, normalize the different browser implementations - not sure the Angular does this.

My suggestion would be to use the json pipe to look at the keyEvent object like:

<string>Event:</strong>{{ keyEvent | json }}<br>
