I have a question about the $scope values.
Example :
$scope.editItem = $scope.data.item;
So in $scope.editItem I have the same value as $scope.data.item.
But If I modify a value in $scope.editItem, the value is changing too in $scope.data.item.
I'm creating an edition form in a grid, and I'd like to edit items without changing the original value.
So if the user begin to edit the row, and cancel then I need to get back the original datas in my $scope.editITem object.
This happens because you're assigning a reference to $scope.data.item, not copying the value.
In order to achieve what you want, you need to deep copy your object using
$scope.editItem = angular.copy($scope.data.item)
As long as I understand you only want to copy the value from one variable into another instead of the reference. A dummy way I know to accomplish that is to use angular.copy (doc) so that you can get this
$scope.editItem = angular.copy($scope.data.item)
It's happening because you are assigning reference to $scope.data.item. So as the reference/address is same for both scope variables, it's updating whenever you are updating $scope.editItem. (two-way binding concept)
So, all you have to do is, assign a copy of $scope.data.item to $scope.editItem. Then your problem'll be fixed.
Do as follow:
$scope.editItem = angular.copy($scope.data.item)
