html.beginForm post List<strongly typed> 的空值通过 jQuery Ajax 函数在 ASP>NET-MVC5 中传递给控制器
html.beginForm post null value for List<strongly typed> to controller via jQuery Ajax function in ASP>NET-MVC5
我有 ASP.net-mvc5 网站。我需要允许用户更新/编辑两个紧急联系方式。为了实现这一点，我将 "list myModel" 发送到剃刀视图，并且在视图中我得到了两个 @html.beginform。我有 List 因为我知道我总是有两条记录。我正在通过记录 1 的索引 0 和记录 2 的索引 1 从列表中打印值。Jquery Ajax 函数用于 post 数据返回控制器。
现在紧急联系人详细信息 1 的表格 1 工作正常，但第二个紧急联系人详细信息的表格 2 post正在向控制器发送空值。我有 commet form1 并尝试提交 form2 但仍然是空值。我不确定为什么会这样。

您对不同的表单使用相同的控制器 post 操作。
您的操作更新模型（实体列表）仅出现在第一位的实体。
您的模型有一个 [entity0, entity1] 列表，但在表单视图中您删除了 entity0，因为您只从具有列表的模型中绑定了一个 entity1。
这里有两种方法：
使 post 控制器动作更通用
public ActionResult EditEmergencyContact (List<EmergencyContact> _emergencyContactModel)
{
try
{
if (_emergencyContactModel != null && _emergencyContactModel.Count() > 0)
{
if (ModelState.IsValid)
{
bool validation = true;
for (int i = 1; i < _emergencyContactModel.Count(); i++)
{
if (_emergencyContactModel[i].EmergencyContactID != null)
{
int _entityID = _studentProfileServices.EditEmergencyContactByStudentID(
new EmergencyContact
{
EmergencyContactID = _emergencyContactModel[i].EmergencyContactID,
StudentID = _emergencyContactModel[i].StudentID,
NameOfContact = _emergencyContactModel[i].NameOfContact,
Relationship = _emergencyContactModel[i].Relationship,
Telephone = _emergencyContactModel[i].Telephone,
Mobile = _emergencyContactModel[i].Mobile,

});
if (_entityID == 0)
{
validation = false;
break;
}
}
}
if (validation)

您从列表中更新两个实体的控制器：
int _entityID_0 = _studentProfileServices.EditEmergencyContactByStudentID(

{
EmergencyContactID = _emergencyContactModel[0].EmergencyContactID,
StudentID = _emergencyContactModel[0].StudentID,
NameOfContact = _emergencyContactModel[0].NameOfContact,
Relationship = _emergencyContactModel[0].Relationship,
Telephone = _emergencyContactModel[0].Telephone,
Mobile = _emergencyContactModel[0].Mobile,
Address = _emergencyContactModel[0].Address
});
int _entityID_1 = _studentProfileServices.EditEmergencyContactByStudentID(
new EmergencyContact
{
EmergencyContactID = _emergencyContactModel[1].EmergencyContactID,
StudentID = _emergencyContactModel[1].StudentID,
NameOfContact = _emergencyContactModel[1].NameOfContact,
Relationship = _emergencyContactModel[1].Relationship,
Telephone = _emergencyContactModel[1].Telephone,
Mobile = _emergencyContactModel[1].Mobile,
Address = _emergencyContactModel[1].Address
});
if (_entityID_0 != 0 && _entityID_1 != 0)
{
return Json(new { Response = "Success" });

else

Your approach is very bad, you should update address one by one not a complex list of address.
