I have information structured like this:
$scope.cart={"4": {"cost": 802.85, "description": "test", "qty": 1},
"5": {"cost": 802.85, "description": "test", "qty": 1}};
My goal is to iterate through this data and show it with a remove button. How can I set up the button to delete the row from the scope and trigger an angular digest? Most tutorials deal with data in arrays and splicing them, which isn't suitable for my situation.
This is my progress so far: http://jsfiddle.net/wbebc4cd/1/
As per @dfsq's observation, it appears there is a typo in your function.
Additionally, when iterating over the map, it is crucial to remember the key as well. For further information, refer to How to use ng-repeat to iterate over map entries in AngularJS
<tr ng:repeat="(key,item) in cart">
This way, you can utilize the key to eliminate the specific item.
<td>[<a href ng:click="removeItem(key)">X</a>]</td>
Access the following link for more details and illustration: http://jsfiddle.net/wbebc4cd/5/
Follow this code snippet for removing the desired item from the list.
function CartForm($scope) {
$scope.cart=[{"id": 1, "cost": 802.85, "description": "test", "qty": 1}, {"id": 2, "cost": 802.85, "description": "test", "qty": 1}];
$scope.removeItem = function(item) {
var index = $scope.cart.indexOf(item);
$scope.cart.splice(index, 1);
}
}
Here is a potential solution for removing an item from the cart:
$scope.removeItem = function(item) {
var newCart = {};
angular.forEach($scope.cart, function(value, key){
if(value != item)
newCart[key] = value;
});
$scope.cart = newCart;
};
