AngularJS $broadcast with multiple parameters

Question

Can I have a $broadcast $on with multiple parameters, something like:

$scope.$broadcast('event',$scope.item, $scope.item); 

Is it possible to have something like this or something similar in any case ?

Answer 1

Just put the parameters into an object:

$scope.$broadcast('event', { a: item1, b: item2 }) 

Then access them from the second argument to the callback:

$scope.$on('event', function(event, opt) {  // access opt.a, opt.b }); 

Or if using ES2015 syntax you can unpack the arguments:

$scope.$on('event', (event, {a,b}) => {  // access them just as a, b });
