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:

1. angular.module('myApp', []): This creates a new module called myApp and sets it up for use in the application.

2. .controller('MyCtrl', function($scope) {: This creates a new controller called MyCtrl and sets up the scope of the controller.

3. $scope.onKeyDown = function(event) {: This creates a new function called onKeyDown and sets it up to be called when the keydown event is triggered.

4. if (event.keyCode === 13) {: This checks the keyCode of the pressed key. If the keyCode is 13, then the code inside the if statement will be executed.

5. alert("Enter was pressed!");: This triggers an alert that says "Enter was pressed!"
