在ASP.NET CORE 2.0中，我正在创建一个Ajax表单。可以用此表格更新多个员工。有一个雇员编号和一个多选列表框，用于选择雇员的报销。
问题是如何处理偿还额，因为可以从列表框中选择多个项目。表格将作为键值对提交。在报销的情况下，键为报销且值将是多个。因此，如何检查为哪个选择了什么报销EmployeeID？
@model myweb.NewWOModel
<form id="frmWODetail" asp-action="EditMultipleEmployee" asp- controller="WOData" data-ajax="true" data-ajax-method="POST" data-ajax-success="onSuccess" data-ajax-failure="onFailed">
@Html.AntiForgeryToken()
<div class="row">
<div class="col-sm-12">
@foreach (var record in Model.MultipleEmployeeModels)
{
<div class="row">
<div class="col-sm-6">
<label>WorkOrder No.:</label>
<span>
@record.EmployeeNo
</span>
</div>
<div class="col-sm-6">
<input type="hidden"
name="EmployeeID"
value="@record.EmployeeID" />
</div>
</div>
<div class="row col-sm-12">
<select name="Reimbursement"
asp-for="@record.ReimbursementID"
asp-items="@(new SelectList(
Model.ReimbursementModels,
"ReimbursementID",
"ReimbursementName")
)"
multiple>
</select>
</div>
}
<div class="row">
<div class="col-sm-12 text-right">
<input type="submit"
class="btn btn-success"
value="Save"/>
<input type="button"
class="btn btn-primary"
value="Close"
data- dismiss="modal" />
</div>
</div>
</div>
</form>
<script type="text/javascript">
var onComplete = function () {
};
var onSuccess = function (context) {
};
var onFailed = function (context) {
};
</script>

[HttpPost]
[ValidateAntiForgeryToken]
public async Task<JsonResult> EditMultipleEmployee(EmployeeModel empModel)
{
//CODE HERE HOW TO HANDLE LIST BOX VALUES FOR EACH EMP
}
模型
public class EmployeeModel
{
public string[] Reimbursement{get; set;}
public string[] EmployeeID{get; set;}
}
public class NewWOModel
{
public List<MultipleEmployeeModels> MultipleEmployeeModels{get; set;}
public List<ReimbursementModel> ReimbursementModels{get; set;}
}
public class MultipleEmployeeModels
{
public string EmployeeNo{get; set;}
public int EmployeeID{get; set;}
}
public class ReimbursementModel
{
public int ReimbursementID{get; set;}
public string ReimbursementName{get; set;}
}
由于您在“雇员”与“报销”之间存在关系，因此您需要更改模型以反映这种关系（您只有2个独立的集合）。您需要以下视图模型
public class EmployeeVM
{
public int EmployeeID { get; set; }
.... // other properties of Employee that you want in the view
public int[] SelectedReimbursements { get; set; } // the selected reimbursements for an employee
}
public class EmployeeCollectionVM
{
public List<EmployeeVM> Employees { get; set; }
public IEnumerable<ReimbursementModel> ReimbursementOptions { get; set; }
}
然后在GET方法EmployeeCollectionVM中将和的实例传递给视图，
@model EmployeeCollectionVM
<form id="frmWODetail" asp-action="EditMultipleEmployee" ....... >
....
@for(int i = 0; i < Model.Employees.Count; i++)
{
<input type="hidden" asp-for="Employees[i].EmployeeID />
<select asp-for="Employees[i].SelectedReimbursements" asp-items="@(new SelectList(Model.ReimbursementOptions,"ReimbursementID","ReimbursementName"))" multiple></select>
....
</form>
它将回发到
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<JsonResult> EditMultipleEmployee(EmployeeCollectionVM model)
