Getting the values of $scope variables from AngularJS in the controller to the view

I have a simple scope variable on my AngularJS Controller. It is assigned a specific endpoint value like this:

$scope.isItAvailable = endpoint.IS_IT_AVAILABLE;

How can I properly use it in my view (HTML) to conditionally show or hide an element using ng-if based on its boolean value?

I attempted to achieve this by implementing a function ctrl.checkIfavailable, and calling it in the HTML, but unfortunately, the value is not being read on the view side.

For example:

  $scope.checkIfItIsAvailable = () => {
    return $scope.isZKAvailable
  }

I then tried using this function in the ng-if. I also tried defining it in the controller, but had no success.

When I console.log the response from the server, I receive a boolean value of either true or false, depending on the situation.

Here is how I wrote the HTML code:

<div class="col-lg-8" ng-if="Ctrl.isItAvailable">
.... // Additional code here
</div>

In the controller, I have the following code:

  $scope.isItAvailable = endpoint.IS_IT_AVAILABLE;

  console.log(endpoints.IS_IT_AVAILABLE); // This returns the desired boolean value

Current Outcome Currently, when I leave the ng-if as it is, the element remains hidden as it does not access it at all.

Expected Outcome I aim to display/hide the element based on the value of isItAvailable.

Answer №1

To access the $scope attached item, simply use it like this:

<div class="col-lg-8" ng-if="isItAvailable">

</div>

If you prefer using the ControllerAs syntax, set isItAvailable to this instead of $scope in the controller. Then, in the view, name the controller as

ng-controller="yourControllerName as Ctrl"
. You can then reference isItAvailable as Ctrl.isItAvailable.
