angularjsHow can I use an enum in an AngularJS application?
Enums in AngularJS applications are used to define a set of named constants. This can be useful when you want to define a set of values that will not change over time.
Here is an example of how to use an enum in an AngularJS application:
// Define an enum
var Color = {
RED: 'red',
GREEN: 'green',
BLUE: 'blue'
};
// Use the enum in a controller
angular.module('myApp', [])
.controller('MyController', function($scope) {
$scope.selectedColor = Color.RED;
});
The code above defines an enum called Color
with three values (RED
, GREEN
, and BLUE
). The enum is then used in a controller to set the initial value of a scope variable called selectedColor
to RED
.
Code explanation
-
var Color = { ... }
: This is the definition of the enum. It is an object literal with three properties (RED
,GREEN
, andBLUE
) that each have a string value. -
angular.module('myApp', [])
: This is the definition of an AngularJS module. -
.controller('MyController', function($scope) { ... }
: This is the definition of a controller. It takes a$scope
parameter, which is used to set the value ofselectedColor
toRED
. -
$scope.selectedColor = Color.RED;
: This is the statement that uses the enum to set the value ofselectedColor
toRED
.
