How to use a keypress, keydown event on enter key press in AngularJS?

User keycode:

<input ng-model="query" ng-keydown="$event.keyCode === 13 && searchItem()">

<input ng-model="inputdata" ng-keydown="searchItem()">

Now,  let's add keyboard support.

trigger by enter key:

<input ng-model="inputdata" 
ng-keydown="$event.keyCode === 13 && searchItem()">

by space key:

<input ng-model="inputdata" 
ng-keydown="$event.keyCode === 32 && searchItem()">

by space or enter key:

<input ng-model="inputdata" 
ng-keydown="($event.keyCode === 13 || $event.keyCode === 32) && searchItem()">

if you are in modern browser

<input ng-model="inputdata" 
ng-keydown="[13, 32].includes($event.keyCode) && searchItem()">
