I need to send data of (product.cant, product.price, product.iditem) and this is my controller code

$scope.saveCart = function(product){
$scope.products = {id_item:product.iditem, val:product.cant, price:product.price};
whe my controller recived (var product) this show me an error of the ( TypeError: Cannot read property ‘cant’ of undefined ) and the semething the other var.

Please help me wich is my error

Did you define product in your controller as a scope variable, something like:

$scope.product = { id_item: 1, img: 'path/to/image', description: 'A product', price: 23.45, .... };

If not, the saveCart function simply gets an undefined object which has no properties at all (which would explain the message ‘cannot read property x of undefined’).
