angularjs - Reuse a function inside another controller which is not attached with view -


i trying reuse function inside controller belongs page. has not been attached view of current page. followed these steps:

  1. include controller using script tag
  2. use $on , $emit in order call function

unfortunately, nothing happened. controller still initialized not receive calling $emit.

i appreciate if can me figure out.

why want that? angularjs has concept services meant purpose - code reusability. need create service, , inject in controllers use it. see below.

app.service('hexafy', function() {    this.myfunc = function (x) {      return x.tostring(16);    } });

and in controller,

app.controller('myctrl1', function($scope, hexafy) {    $scope.hex = hexafy.myfunc(255); });  app.controller('myctrl2', function($scope, hexafy) {     $scope.hex = hexafy.myfunc(1023); });

remember services in angular singleton.
