数组中的angularjs对象上没有$$ hashKey

Question

$scope.create (in CreateCtrl) and $scope.list (inListCtrl) linked to DOM For some reason, $ $ hashKey not added to all objects. The last object is left without him. That is, if I added 3 items, the third less $ $ hashkey if add another, then a third appears hashkey $ $, and the fourth is not.

Because of this error appears: Error: [ngRepeat:dupes]

track by $index does not offer. Then sorting stops working.

app.controller('CreateCtrl', function ($scope) {
   $scope.create = {a:1, b:2, c:3};
   $scope.send = function () {
      $scope.$emit('send', angular.copy($scope.create));
   }
});

app.controller('ListCtrl', function ($scope, $rootScope) {
   $scope.list = [];
   $rootScope.$on('send', function (e, data) {
      $scope.list.push(data);
   });
});

Answer 1

You're passing a javascript object {} with three elements and then pushing that whole object into the first index of $scope.list

$rootScope.$on('send',function(e,data){
    angular.forEach(data,function(value,key){
        $scope.list.push(value); // or $scope.list[key] = value;
    });
});

Your values are at data.a , data.b and data.c
