我使用ng-grid，我有一个数组来存储我的数据。
$scope.list = [{...},{...},{...}]
现在我想更新一个对象（即连续）中的数据：
我尝试了$scope.list[index] = {...}并更改了其值，但HTML中没有更新任何内容。
下面的方法适合我，但我认为它们并不是那么漂亮。
arr = angular.copy($scope.list)
arr[index] = {...}
$scope.list = arr
或
$scope.list[index].attr_1 = sth;
$scope.list[index].attr_2 = sthElse;
...
更新：
$scope.pickProduct = ()->
$scope.errorMessage = ''
$http.post('/api/delivery_items/pick.json',
barcode: $scope.scannedBarcode
).success((data, status, headers, config) ->
$scope.scannedBarcode = ''
angular.forEach $scope.picklist, (row, index) ->
if row.id == data.id
# I update the data but it doesn't change the row in HTML
$scope.picklist[index] = data.delivery_item
).error((data, status) ->
if data.status is 'nok'
$scope.scannedBarcode = ''
$scope.errorMessage = data.message
)
