Being a newcomer to angularjs, I am exploring ways to display an html element based on a property of the $scope object without utilizing any form element.
Here is the code snippet:
<div id="ListApp">
<div ng-controller="ListCtrl">
{{ myData.prova }}: {{ myData.logged }}
<div id="secretContent" ng-show="myData.logged">
<ul>
<li ng-repeat="elemento in lista">
<input type="checkbox" ng-model="elemento.comprato" />
<span ng-if="!elemento.comprato">{{ elemento.nome }}</span>
<span ng-if="elemento.comprato" style="text-decoration:line-through;">{{ elemento.nome }}</span>
</li>
</ul>
<input type='text' id='input_nome'/><button ng-click="aggiungi()">Aggiungi</button>
</div>
</div>
</div>
And here is the controller section:
<script>
var listaViaggio = angular.module('listApp', ['directive.g+signin']);
listaViaggio.controller('ListCtrl', ['$scope',function ListCtrl($scope) {
$scope.lista = [];
$scope.myData={};
$scope.myData.prova="test";
$scope.myData.logged=0;
$scope.aggiungi = function(){
$scope.lista.push({
'nome':document.getElementById("input_nome").value,
'comprato':false
});
};
$scope.$on('event:google-plus-signin-success', function (event, authResult) {$scope.myData.logged=1;console.log($scope.myData.logged);});
$scope.$on('event:google-plus-signin-failure', function (event, authResult) {$scope.myData.logged=0;console.log($scope.myData.logged);});
}]);
</script>
Upon examining the code, it's evident that I am altering the status of $scope.myData.logged upon google+ sign in. I expect the div with id secretContent to be displayed or hidden based on this property. However, I've noticed that the truth value of ng-show is only evaluated once and is not dynamically linked to the actual property value. Therefore, even if the property changes, the display remains static.
What could be the issue in my code? What is the correct logic flow of the ng-show command and how can I establish a binding to a $scope property?
Thank you in advance for any insights.
