If the two controller is nested in One controller  Then you can simply call         scope parentmethod        Angular will search for parentmethod function starting with current scope and up until it will reach the rootScope

If you would like to execute the parent controller s parentmethod function inside a child controller  call it     scope  parent parentmethod      You can try it over here

You may use events to provide your data  Code like that   app controller  One      scope   function   scope              scope parentmethod function                      scope  emit  one   res     res - your data                         app controller  two      scope   function   scope              scope  on  updateMiniBasket   function  event  data

The best approach for you to communicate between the two controllers is to use events   See the scope documentation  In this check out  on   broadcast and  emit

I wouldn t use function from one controller into another  A better approach would be to move the common function to a service and then inject the service in both controllers

User · Answer

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
