Properly accessing values in a set object: a practical guide

Within my ng-controller, I am currently utilizing a small snippet of code that looks something like this:

<select ng-model="character" ng-options="ch.name for ch in characters"></select>

{{character}} <-- Works well, even {{character.attr}} functions correctly

{{attr}} <-- Unfortunately, does not update when the selection changes*

...function($scope){

$scope.character = characters[0]; <-- Successfully retrieves and sets object as expected

$scope.attr = $scope.character.name; <-- However, it only initializes a value*
                                      which remains unchanged when the selection is altered

}

$scope.attr = character.name, $scope.attr = $scope.character['name']
, do not yield results. Consequently, functions such as these will never be successful:

$scope.attack_array = function(i){  <-- Unable to send a field or whole object **
  let character = characters[i];
  let array..
}

$scope.attack_array($scope.character.index) <-- How can I access individual values for each field?

Answer №1

Switch the perspective to this

<select ng-model="character" ng-init="character = characters[0]" ng-options="ch.name for ch in characters"></select>

You can retrieve the chosen value by using

$scope.attr = $scope.character.name;
. I trust this solution will be effective. Keep me posted if you require any additional assistance.
