extracting a string from an array in Angular

As I am relatively new to Angular, I am seeking advice on how to create a variable inside the controller based on an array position.

So far, I have successfully declared the following variables:

$scope.chosenCategory = 1;
$scope.categoryNames = ["site", "country", "customer", "type"];

I attempted to accomplish this by using the following code snippet, however, it caused all the angular expressions in the controller's template to cease functioning:

$scope.aspect = categoryNames[chosenCategory];

The expected outcome is for the variable to display the string "country" initially.

Your assistance in solving this issue would be greatly appreciated. Thank you in advance.

Answer №1

Make sure to use $scope.categoryNames instead of simply categoryNames in your array, and ensure that $scope.chosenCategory is correctly referenced as $scope.chosenCategory. Update your code snippet as follows:

$scope.aspect = $scope.categoryNames[$scope.chosenCategory];

Answer №2

Use $scope in order to gain access to controller variables

$scope.aspect = $scope.categoryNames[$scope.chosenCategory];
