Question

我有一个带下拉列表的表单：

<select class="form-control input-sm" 
    ng-disabled="!editMode" 
    ng-model="case.LawyerParticipation.LawyerID" 
    ng-options="lawyer.ID as lawyer.Name for lawyer in lawyers" 
    ng-change="changed()"></select>

默认LawyerID值为“null”。当激活更改事件时，“更改”功能显示“case.LawyerParticipation.LawyerID”的值：

$scope.changed = function () {
     alert($scope.case.LawyerParticipation.LawyerID);
};

它表明模型改变了我的预期。 $ scope.case.LawyerParticipation.LawyerID更改为我在下拉列表中选择的值。下一步我想在服务器上发送此值。我点击提交按钮并激活“updateCase”功能：

$scope.updateCase = function () {
    alert($scope.case.LawyerParticipation.LawyerID);

    $http.post("/case/update", $scope.case ).success(function (updatedCase) {
        $scope.case  = updatedCase;
    });
};

此功能中的提醒显示我可以和“LawyerID”具有新的价值。然后“发布”发生在控制台中我看到服务器上发布的模型有LawyerID =“null”，它在服务器上也是空的！我做错了什么？为什么它是空的？

您的服务器代码中可能会出现一些拼写错误，请将您的服务器代码添加到问题中。

$scope.updateCase = function () {
    alert($scope.case.LawyerParticipation.LawyerID);

    $http.post("/case/update", {data:$scope.case} ).success(function (updatedCase) {
        $scope.case  = updatedCase;
    });
};

Angularjs选择“假”模型更新
