I have an app which I am building with angular, I have about 8-10 views to build out. All the views have a shared footer, based on the view and a set of business rules i need to conditionally show / hide some of the content on the footer.
So. I have controllers for each view, and then one for the footer. I include the common footer layout using ng-include, where the html I am including references the footer controller in the ng-controller.
Index.html
<body ng-controller="MainCtrl as vm">
<p>Message from Main Controller '{{vm.mainMessage}}'</p>
<div ng-include="'commonFooter.html'"></div>
</body>
commonFooter.html
<div ng-controller="FooterCtrl as vm">
<p>Message from Footer Controller '{{vm.message}}'</p>
<p ng-show="vm.showSomthing">Conditional footer Content</p>
</div>
I want each views controller to determine the state of the footer and whether specific content is hidden or not. (shouldDisplaySomthingInFooter below)
app.controller('MainCtrl', function($scope) {
var vm = this;
vm.mainMessage= 'HEELO';
vm.shouldDisplaySomthingInFooter = true;
window.console.log('Main scope id: ' + $scope.$id);
});
Then i had intended that in the FooterController would reach back into the parent controller and pull out the specific settings to enable / disable content based on the business rules.
app.controller('FooterCtrl', function($scope) {
var vm = this;
vm.message = 'vm footer';
window.console.log('Footer scope id: ' + $scope.$id);
window.console.log('Footer parent scope id: ' + $scope.$parent.$id);
window.console.log('Footer grandparent scope id: ' + $scope.$parent.$parent.$id);
window.console.log('Footer grandparent scope name: ' + $scope.$parent.$parent.mainMessage);
window.console.log('Footer grandparent scope condition: ' + $scope.$parent.$parent.shouldDisplaySomthingInFooter);
vm.showSomthing = false; //how to pull from parent scope to bind the ng-show to a value set in the parent from within a ng-include?
});
I have this example here: http://plnkr.co/edit/ucI5Cu4jjPgZNUitY2w0?p=preview
What I am finding is that I when I reach into the parent scope to pull out the content it is coming back as undefined, and I am not sure why.
I can see that the scopes are nested to the grandparent level by checking the scopeid, I believe this is because the ng-include adds an extra scope layer below the view scopes.
Extra points: If i can not have to use the $scope object and can stick with the var vm = this; way of doing it that would be preferable. But beggars cant be choosers :)
app.controller('MainCtrl', function($scope) {
var vm = this;
Thank you very much in advance.
