当数组被推入范围内时，ng-repeat 不会更新

Question

我有一个 Web 方法，它在每次调用中返回 json 数据，我将此结果推送到 $scope 变量中，但在 ng-repeat 内部它没有绑定此结果。我的代码有什么问题。请建议。这是我的代码

[WebMethod(EnableSession = true)]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public string GetLocationStockEntries(int LocationId, int ProductId)
    {
        var jsonText = (dynamic)null;       
        try
        {

            if (LocationId > 0)
            {
                Int64 BusinessUnitId = 0;
                using (var db = new repute.Data.ReputEntities())
                {
                    var temp = db.Inventories.Where(p => p.InventoryID == LocationId).FirstOrDefault();
                    BusinessUnitId = temp == null ? 0 : Convert.ToInt64(temp.BusinessUnitID);
                    var StockData = db.usp_mvc_InventoryItems_GetAllEntriesByLocation(LocationId, ProductId, BusinessUnitId).Where(x => x.ProjectedQuantityOnHand > 0).ToList();
                    jsonText = JsonConvert.SerializeObject(new { data = StockData });
                }
            }          
        }
        catch (Exception ex)
        {

        }
        return jsonText;
    }

js :function 每次都调用此 web 方法并将这些结果推送到 $scope 变量

function GetStockEntries(loid, pid)
    {
        return $http.post(serviceURL + "/GetLocationStockEntries", {LocationId: loid, ProductId: pid }).then(
function success(data, status, headers, config) {
    var obj = JSON.parse(data.data.d);
    debugger
    //$scope.result = obj.data;
    $scope.result = obj;
    angular.forEach($scope.result, function (key) {
        $scope.StockList.push(key);
    })

},
  function error(data, status, headers, config) {
      return data;
  });
}

Html:

                    <table cellpadding="5" cellspacing="0" data-ng-repeat="sTockProduct in ProductList" data-ng-cloak>
                        <tr>
                            <td>{{sTockProduct.Name}} 
                                <i class="fa fa-expand" aria-hidden="true" style="color: #000000; text-align: right; margin:5px 0px 0px 10px;" data-ng-click="StockListing(sTockProduct);"></i></td>

                        </tr>
                        <tr>
                            <td>
<table cellpadding="5" cellspacing="0" data-ng-repeat="stockItem in StockList track by $index" data-ng-show = "IsVisible" data-ng-cloak width="100%">                                            
    <tr style="border-bottom: 1px solid #ddd; padding-bottom: 5px; margin-bottom: 5px; float: left;">
        <td>
            <input type="radio" name="groupName" data-ng-value="true" data-ng-model="stockItem.selected[$index]" data-ng-click="onTaskSelect(stockItem,sTockProduct)" />
        </td>
        <td>
            <input type="text" data-ng-model="stockItem.UserInventoryItemID" disabled="" readonly="" style="border: none; background-color: white;">
        </td>
        <td>
            <input type="text" data-ng-model="stockItem.LotNumber" disabled="" readonly="">
        </td>
        <td>
            <!--<input type="text" data-ng-model="stockItem.QuantityOnHand" disabled="" readonly="">-->
            <span>{{stockItem.QuantityOnHand}}</span>
            <span>{{stockItem.UnitName}}</span>
        </td>
        <td>
            <input type="text" data-ng-model="stockItem.EnteredQuantity" >
        </td>
        <td>
            <input type="text" data-ng-model="stockItem.Description" disabled="" readonly="">
        </td>
     </tr>
 </table>
 </td>
                                </tr>
                            </table>

这是json的结果

我想问题出在你身上 ng-repeat.try 类似的东西，如果两个项目中的某些东西相似，请检查那里的条件。在你内心 table 做

data-ng-if="stockItem.ProductID== sTockProduct.ProductID"

应该是这样的：

<table cellpadding="5" cellspacing="0" data-ng-repeat="stockItem in StockList track by $index" data-ng-if="stockItem.ProductID == sTockProduct.ProductID" data-ng-cloak width="100%">

并在您的成功中稍作修改：

替换：

$scope.result = obj;

至：

$scope.result = obj.data;

当数组被推入范围内时，ng-repeat 不会更新

ng-repeat is not updating when array is pushed inside scope

javascript

json

http

webmethod
