Struggling to make ng-show display a div after it has been hidden by ng-click

Within my view, the HTML code I have written appears as follows:

<div ng-show="show_alert_message" ng-bind-html="alert_message"
     class="alert-message-container"
     ng-click="show_alert_message=!show_alert_message"></div>

To initially display the div, I set the value of $scope.show_alert_message to true in the controller:

$scope.show_alert_message = true;

When the user clicks on the div to close it, the ng-click function toggles show_message_alert to false. This behavior successfully hides the div. However, if I attempt to show the div again by setting $scope.show_alert_message to true once more in the controller, it remains hidden:

$scope.show_alert_message = true;

It seems that the functionality of ng-click prevents me from displaying the div again.

Am I making a mistake? Both instances where $scope.show_alert_message is set to true should be identical to the scope of ng-click="show_alert_message=false". Therefore, I am unsure why the second declaration of $scope.show_alert_message = true does not work while the first one does.

Answer №1

After creating a snippet that meets your requirements, take a closer look at the scope you are using when triggering 

$scope.show_alert_message = true;
. It seems like this is where the issue lies and needs to be addressed.

var $scope = {};

var myApp = angular.module('myApp', []);

myApp.controller('ngShowCtrl', ['$scope', function($scope){
  $scope.show_alert_message = true;
  $scope.alert_message = "I'm an alert message!"
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="myApp" ng-controller="ngShowCtrl">
  <div 
       ng-show="show_alert_message" 
       ng-bind="alert_message"
       class="alert-message-container"
       ng-click="show_alert_message=!show_alert_message"
  ></div>
  <button type="button" ng-click="show_alert_message=!show_alert_message">Show/Hide</button>
  
</div>

Answer №2

implement ng-if="display_warning" along with ng-click="toggleDisplay()" and 

$scope.toggleDisplay=function(){
  setTimeout(function(){
      $scope.display_warning=! $scope.display_warning;
      //$scope.$apply();
  },0);

}
