I’m trying to perform an action when a specific accordion-section is openend. My use-case is almost identical to this question here, only I’m using statically defined ‘s instead of ng-each.
Somehow I can’t get the $watch to fire when the is-open state changes, can anybody tell me why this doesn’t work:
View:
<accordion close-others="false"> <accordion-group heading="group1" is-open="acc1open"> content 1 </accordion-group> <accordion-group heading="group2" is-open="acc2open"> content 2 </accordion-group> </accordion>
Controller:
$scope.acc1open = false; $scope.acc2open = true; $scope.$watch('acc1open', function(){ console.log("watch acc1:" +$scope.acc1open); }, true);
Here’s a plunker:

It prints “watch acc1:false” a single time when the page is loaded, but nothing when the accordion group is opened.
Answer
I added a <span>
inside the AccordionDemoCtrl div and changed the is-open to bind to $parent.acc1open
<accordion-group heading="group1" is-open="$parent.acc1open">
…
<span ng-click="acc1open = true">Click me to open group 1</span>
Directives have their own scope, and the variables are their own.
