I would say a more proper way (or "Angular way") would be to add it to a directive. Here's a simple one to get you going (just add keypress-events
attribute to <body>
):
angular.module('myDirectives', []).directive('keypressEvents', [
'$document',
'$rootScope',
function($document, $rootScope) {
return {
restrict: 'A',
link: function() {
$document.bind('keypress', function(e) {
console.log('Got keypress:', e.which);
$rootScope.$broadcast('keypress', e);
$rootScope.$broadcast('keypress:' + e.which, e);
});
}
};
}
]);
In your directive you can then simply do something like this:
module.directive('myDirective', [
function() {
return {
restrict: 'E',
link: function(scope, el, attrs) {
scope.keyPressed = 'no press :(';
// For listening to a keypress event with a specific code
scope.$on('keypress:13', function(onEvent, keypressEvent) {
scope.keyPressed = 'Enter';
});
// For listening to all keypress events
scope.$on('keypress', function(onEvent, keypressEvent) {
if (keypress.which === 120) {
scope.keyPressed = 'x';
}
else {
scope.keyPressed = 'Keycode: ' + keypressEvent.which;
}
});
},
template: '<h1>{{keyPressed}}</h1>'
};
}
]);
