angularjs - Propagating model changes to a Parent Controller in Angular -


i have angularjs application , try simulate asana.com feature.

the scenario following:

asana

i have maincontroller application in body tag, , inside controller populate names in sidebar:

.controller('maincontroller', ['$scope', 'namesservice', function($scope, namesservice) {     $scope.names = namesservice.query();     ... };

when click on name (for example, anna), application change route , in inject name-edit.html template in ng-view, represented content area on picture above. have input used change anna carol , update button. when hit update button, fires function updates in database, changes anna carol in content area (represented yellow arrow position) doesn't change red arrow position in sidebar.

i tried call following code again inside success update callback, doesn't work

$scope.names = namesservice.query();

i'd know how propagate child controller parent controller, changing anna carol inside $scope.names. possible this, without reloading $scope.names?

you use event system of angular using $scope.$emit('eventname', eventdata) un child controller pass data on hierarchy. 

//child, assuming have promise callback namesservice.query().then(function(data){    $scope.$emit('eventname', data) })

and in parent controller have following

//parent $scope.$on('eventname', function(event, data){    $scope.names = data; })

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
