Issue
I need to call a function in another controller in AngularJS. How can I do this?
Code:
app.controller('One', ['$scope',
function($scope) {
$scope.parentmethod = function() {
// task
}
}
]);
app.controller('two', ['$scope',
function($scope) {
$scope.childmethod = function() {
// Here i want to call parentmethod of One controller
}
}
]);
Solution
Communication between controllers is done though $emit
+ $on
/ $broadcast
+ $on
methods.
So in your case you want to call a method of Controller "One" inside Controller "Two", the correct way to do this is:
app.controller('One', ['$scope', '$rootScope'
function($scope) {
$rootScope.$on("CallParentMethod", function(){
$scope.parentmethod();
});
$scope.parentmethod = function() {
// task
}
}
]);
app.controller('two', ['$scope', '$rootScope'
function($scope) {
$scope.childmethod = function() {
$rootScope.$emit("CallParentMethod", {});
}
}
]);
While $rootScope.$emit
is called, you can send any data as second parameter.
