Definitie en gebruik

ng-keydown Het commando vertelt AngularJS wat te doen wanneer de toetsenbord wordt gebruikt op een specifiek HTML-element.

AngularJS' ng-keydown Directives do not override the original onkeydown event of the element, both will be executed.

The order of keystrokes is:

1. Keydown (Keyboard Pressed)
2. Keypress (Keyboard Press)
3. Keyup (Keyboard Release)

Example

Execute an expression each time a key is pressed:

<input ng-keydown="count = count + 1" ng-init="count=0" />
<h1>{{count}}</h1>
