angularjsHow can I use the AngularJS keydown event to detect when the Enter key is pressed?
The AngularJS keydown event can be used to detect when the Enter key is pressed. To do this, you need to use the keydown
event and check the key code of the pressed key.
Example code
angular.module('myApp', [])
.controller('MyCtrl', function($scope) {
$scope.onKeyDown = function(event) {
if (event.keyCode === 13) {
alert("Enter was pressed!");
}
};
});
Output example
Alert: "Enter was pressed!"
The code above uses the keydown
event to detect when the Enter key is pressed. It checks the keyCode
of the pressed key, which is 13 for Enter. If the keyCode is 13, then an alert is triggered.
The code consists of the following parts:
-
angular.module('myApp', [])
: This creates a new module calledmyApp
and sets it up for use in the application. -
.controller('MyCtrl', function($scope) {
: This creates a new controller calledMyCtrl
and sets up the scope of the controller. -
$scope.onKeyDown = function(event) {
: This creates a new function calledonKeyDown
and sets it up to be called when thekeydown
event is triggered. -
if (event.keyCode === 13) {
: This checks thekeyCode
of the pressed key. If the keyCode is 13, then the code inside theif
statement will be executed. -
alert("Enter was pressed!");
: This triggers an alert that says "Enter was pressed!"
