删除项目实际上并没有将其删除[关闭](Delete item is not actually removing it [closed])

我有一个编辑表单，显示已添加/存储的项目以及删除项目的选项。如果我单击“删除”，“保存”，则会弹出成功消息，但当我返回列表显示时，我刚刚“删除”的项目仍然存在。

这是显示项目旁边带有删除按钮的表格：

<table id="newPatientForm"> <tr> <th>First Name</th> <th>Last Name</th> <th></th> </tr> <tbody data-bind="foreach:Patients"> <tr> <td class="form-group"><input data-bind="value: FirstName, event: {change: flagPatientAsEdited}, hasfocus: true" /></td> <td class="form-group"><input data-bind="value: LastName" /></td> <td class="form-group"><button data-bind="click: $parent.deletePatient">Delete</button></td> </tr> </tbody> </table>

这是我声明“PatientsToDelete”的viewModel

using OnboardingProject.Model; using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace OnboardingProject.Web.ViewModels { public class SiteViewModel : IModel { public SiteViewModel() { Patients = new List<PatientViewModel>(); PatientsToDelete = new List<int>(); } public int SiteId { get; set; } public string Name { get; set; } public string Address { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } public string CreatedOn { get; set; } public string ModifiedOn { get; set; } public ObjectState ObjectState { get; set; } public string MessageToClient { get; set; } // Message sent to client from server to demonstrate data-flow when property is not in db // @TODO: Change to client CompleteAddress public string CompleteAddress { get { return string.Format("{0} {1}, {2} {3}", this.Address, this.City, this.State, this.Zip); } } public List<PatientViewModel> Patients { get; set; } public List<int> PatientsToDelete { get; set; } } }

这是整个js文件：

更新：经过一些调试后，我注意到js文件中的“PatientsToDelete”被列为未定义，即使我在ViewModel中声明它。虽然js文件中还有一些我遗漏的东西吗？

I have an edit form that displays items that have been added/stored with the option to delete items. If I click "Delete", the "Save", the success message pops up, but when I go back to the display of the list, the item that I just "Deleted" is still there.

This is the table that displays the items with the delete button beside them:

<table id="newPatientForm"> <tr> <th>First Name</th> <th>Last Name</th> <th></th> </tr> <tbody data-bind="foreach:Patients"> <tr> <td class="form-group"><input data-bind="value: FirstName, event: {change: flagPatientAsEdited}, hasfocus: true" /></td> <td class="form-group"><input data-bind="value: LastName" /></td> <td class="form-group"><button data-bind="click: $parent.deletePatient">Delete</button></td> </tr> </tbody> </table>

This is the viewModel where I declare "PatientsToDelete"

using OnboardingProject.Model; using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace OnboardingProject.Web.ViewModels { public class SiteViewModel : IModel { public SiteViewModel() { Patients = new List<PatientViewModel>(); PatientsToDelete = new List<int>(); } public int SiteId { get; set; } public string Name { get; set; } public string Address { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } public string CreatedOn { get; set; } public string ModifiedOn { get; set; } public ObjectState ObjectState { get; set; } public string MessageToClient { get; set; } // Message sent to client from server to demonstrate data-flow when property is not in db // @TODO: Change to client CompleteAddress public string CompleteAddress { get { return string.Format("{0} {1}, {2} {3}", this.Address, this.City, this.State, this.Zip); } } public List<PatientViewModel> Patients { get; set; } public List<int> PatientsToDelete { get; set; } } }

This is the entire js file:

UPDATE: After some debugging, it has come to my attention that "PatientsToDelete" in the js file is being listed as undefined even though I declare it in the ViewModel. Is there still something I am missing in the js file though?
