绑定json时出错

Question

我在我的一个程序中使用Angularjs。我用它来添加项目到json数组。然后我将此数组保存到临时文件中。此时程序工作正常。当我尝试将保存的json字符串绑定到表时，我得到错误错误：[ngRepeat：dupes] 在搜索文档时，我发现AngularJS允许通过语法“Track by $ index”重复值，并显示示例重复单维json。我的问题是，如何控制id为

的转发器

jQuery 请注意，如果我删除$ scope。$ apply（），则不会显示任何错误，但也不会显示数据。

$scope.OpenTemp = function () {
    var vFileName = $("#TempList").val();
    $scope.sysmsg = 'Opening voucher from temporary location';
    var to = "../../WHS/OpenTempJV.ashx";
    var options = {
        type: "POST",
        url: to,
        data: { vFile: vFileName },
        error: function () {
            ShowErrorMsg("Error in opening temporary voucher");
        },
        success: function (data) {
            if (data != "") {
                //alert(data.d);
                //$scope.sysmsg = 'success';
                $("#divGrid").show();
                $scope.TDS = $scope.TDS.concat(data);
                //$scope.TDS = data;
                //$scope.$apply();
                //CalcAllTotals(data);
            }
            else {
                ShowErrorMsg("Could not retrieve temporary voucher");
            }
        }
    };
    $.ajax(options);
}
