When I am trying to copy a new object to an old object via angular.copy, its reference gets changed. If I use = or JSON.parse(JSON.stringify(newObj)), the view is not updated with new value.
How can I solve this?
Code example:
$scope.value = newValue.ref;
View is not updated in this instance.
$scope.value = angular.copy(newValue.ref);
View is updated, but reference is changed.
To preserve the reference, use the two argument form of angular.copy:
//$scope.value = angular.copy(newValue.ref);
//USE two argument signature
angular.copy(newValue.ref, $scope.value);
This way the original reference is preserved.
Usage
angular.copy(source, [destination]);Creates a deep copy of
source, which should be an object or an array.
- if a destination is provided, all of its elements (for arrays) or properties (for objects) are deleted and then all elements/properties from the source are copied to it.
