angularjs forEach and splice

Question

I have an array like this:

$scope.emails = [
  {\"key\":\"Work\",\"value\":\"user@domine.com\"},
  {\"key\":\"\",\"value\":\"\"},
   {\"key\":\"Work\",\"value\":         


        

Answer 1

indexOf returns -1 when it doesn't find an item.

A way to remove an item, and to avoid removing the last one when not found, is:

var index = $scope.items.indexOf($scope.oldItem);

if (index != -1) {
  $scope.items.splice(index, 1);
}
