Question

我正在将wcf rest服务用于angular js应用程序。我正在尝试根据帐号获取帐户信息。但问题是它显示文本Account_Type三次然后显示值。

这是方法代码。

    Layout = null;

            $scope.Search = function () {
                var post = $http({
                    method: "GET",
                    url: "http://localhost:52098/HalifaxIISService.svc/AccountDetails/" + encodeURIComponent($scope.Account_Number),

            $scope.grandTotal = function () {
                return $scope.Customers.reduce(function (previousTotal, m) {
                    var valueToAdd = parseFloat(m.Deposit);
                    if (isNaN(valueToAdd))
                        return previousTotal;
                    return previousTotal + valueToAdd;
                }, 0); // Send in 0 as the default previousTotal
            }
            $scope.grandTotal1 = function () {
                return $scope.Customers.reduce(function (previousTotal, m) {
                    var valueToAdd = parseFloat(m.Withdrawal);
                    if (isNaN(valueToAdd))
                        return previousTotal;
                    return previousTotal + valueToAdd;
                }, 0); // Send in 0 as the default previousTotal
            }

        });
    </script>


    <div ng-app="MyApp" ng-controller="MyController">
        Account Number:
        <input type="text" ng-model="Account_Number" />
        <input type="button" value="Submit" ng-click="Search()" />
        <hr />
        <br />         


        <div ng-repeat="m in Customers" ng-show="IsVisible">Account Type:{{m.Account_Type}}</div>       



    </div>
</body>
</html>

这是代码。

 files = (FILES *)malloc(sizeof(FILES));

这是我运行应用程序时的scrren镜头。

如果您需要Account_Type，则此处不需要 ng-repeat 。只需将值赋给$ scope变量

 $scope.Account_Type = details[0].Account_Type;

角度应用程序数据绑定不起作用
