Angular 1.3+ has an alternative getter/setter pattern: You can bind ng-model to an accessor function. This is a function that is either a getter (when it gets no arguments) or a setter (when it gets the new value as an argument):
$scope.name = function(newName) {
return angular.isDefined(newName) ? (_name = newName) : _name;
}
You need to bind this function with ng-model and ng-model-options="{ getterSetter: true } to activate this behavior.
Note that since this executes a function on every read, this is slower than a dumb property.
Full example
Full example from the docs Show archive.org snapshot :
<div ng-controller="ExampleController">
<form name="userForm">
Name:
<input type="text" name="userName"
ng-model="user.name"
ng-model-options="{ getterSetter: true }" />
</form>
<pre>user.name = <span ng-bind="user.name()"></span></pre>
</div>
The JS that goes with it:
angular.module('getterSetterExample', [])
.controller('ExampleController', ['$scope', function($scope) {
var _name = 'Brian';
$scope.user = {
name: function(newName) {
return angular.isDefined(newName) ? (_name = newName) : _name;
}
};
}]);
