我在“同一”问题上经历了很多问题，但似乎没有一个问题适合我（或者我完全忽视了这一点）。
正如主题所说，我试图使用Ajax.ActionLink将值从TextBoxFor传递给我的控制器，但没有任何工作。我试过javascript / jquery并尝试使用我的模型，都返回null：
查看：
@Html.TextBoxFor(m => m.Duplicatename, new { @class = "form-control", @id = "txtDupName", @placeholder = "Enter duplicate name" })
@foreach (var item in Model.MasterBudgets)
{
@{
var optsImportsl = new AjaxOptions()
{
HttpMethod = "GET",
InsertionMode = InsertionMode.ReplaceWith,
UpdateTargetId = "listofBudgets",
//OnBegin = "ImportLoading"
};
}
@if (User.IsInRole("Super Admin"))
{
@Ajax.ActionLink("Duplicate", "Duplicate", "Budget", new { id = item.BudgetId, type = item.Type, dupName = @Model.Duplicatename }, optsImportsl, new { @class = "btn btn-sm btn-black btn-outline", @id = "btnCreate" })
}
}
控制器：
public ActionResult Duplicate(int id, string type, string dupName)
{
var model = _masterRepository.FindMasterBudgetById(id);
if(dupName == null || dupName.Trim() == "")
{
dupName = "Duplicated";
}
if (type == "Master")
{
var duplicate = Duplication(model, dupName);
var masterbudgetId = _masterRepository.Save(duplicate);
var budgets = _masterRepository.GetMasterBudgets
.Where(x => x.ParentMasterBudgetId == id && x.Type == "Budget")
.ToList();
//Budgets
foreach (var item in budgets)
{
var linkedAccounts = _budgetAccountRepository.GetBudgetAccounts
.Where(x => x.BudgetId == item.BudgetId)
.ToList();
var duplicateBudgets = Duplication(item, dupName);
duplicateBudgets.ParentMasterBudgetId = masterbudgetId;
var getId = _masterRepository.Save(duplicateBudgets);
foreach (var account in linkedAccounts)
{
var budgetaccount = new BudgetAccount
{
BudgetId = getId,
BudgetAccountId = 0,
AccountId = account.AccountId,
};
var newaccountId = _budgetAccountRepository.Save(budgetaccount);
}
var linkedBudgetEntries = _budgetEntryRepository.GetBudgetLineEntries(item.BudgetId);
foreach(var lineEntryItem in linkedBudgetEntries)
{
var lineEntries = new Notes_Line_Entries
{
EntryLineId = lineEntryItem.EntryLineId,
fkiAccountId = lineEntryItem.fkiAccountId,
fkiNotesColumnId = lineEntryItem.fkiNotesColumnId,
Value = lineEntryItem.Value,
isNewEntry = lineEntryItem.isNewEntry,
budgetId = getId
};
_budgetEntryRepository.SaveDuplicateLineEntries(lineEntries,item.BudgetId);
}
var subbudgets = _masterRepository.GetMasterBudgets
.Where(x => x.ParentBudgetId == item.BudgetId)
.ToList();
//Sub-Budgets
foreach (var subItem in subbudgets)
{
var subBudgetLinkedAccounts = _budgetAccountRepository.GetBudgetAccounts
.Where(x => x.BudgetId == subItem.BudgetId)
.ToList();
var duplicateSubBudgets = Duplication(subItem, dupName);
duplicateSubBudgets.ParentMasterBudgetId = masterbudgetId;
duplicateSubBudgets.ParentBudgetId = getId;
duplicateSubBudgets.BudgetTypeName = subItem.BudgetTypeName;
duplicateSubBudgets.OrganisationId = subItem.OrganisationId;
var getSubBudgetId = _masterRepository.Save(duplicateSubBudgets);
foreach (var account in subBudgetLinkedAccounts)
{
var budgetaccount = new BudgetAccount
{
BudgetId = getSubBudgetId,
BudgetAccountId = 0,
AccountId = account.AccountId,
};
var newaccountId = _budgetAccountRepository.Save(budgetaccount);
}
var linkedSubBudgetEntries = _budgetEntryRepository.GetBudgetLineEntries(subItem.BudgetId);
foreach (var lineEntryItem in linkedSubBudgetEntries)
{
var lineEntries = new Notes_Line_Entries
{
EntryLineId = lineEntryItem.EntryLineId,
fkiAccountId = lineEntryItem.fkiAccountId,
fkiNotesColumnId = lineEntryItem.fkiNotesColumnId,
Value = lineEntryItem.Value,
isNewEntry = lineEntryItem.isNewEntry,
budgetId = getSubBudgetId
};
_budgetEntryRepository.SaveDuplicateLineEntries(lineEntries, subItem.BudgetId);
}
}
}
Success("Successfully duplicated " + model.BudgetName);
}
return RedirectToAction("BudgetListInfo", new { searchTerm = String.Empty }); //This ActionResult being redirected to, returns a PartialView - This is done so that the items in the Table are returned in correct order(i.e. Parent, then children under the parent and children under the child items)
}
复制功能：
private MasterBudget Duplication(MasterBudget model, string dupName)
{
return new MasterBudget
{
BudgetId = 0,
BudgetName = model.BudgetName + " " + dupName,
BudgetTracker = new Guid(),
FinancialYear = model.FinancialYear,
Description = model.Description,
Status = model.Status,
CreatedDate = DateTime.Now,
CurrentWorkerId = CurrentUser.Id,
OrganisationId = model.OrganisationId,
BudgetTypeName = model.BudgetTypeName,
ParentMasterBudgetId = model.ParentMasterBudgetId,
Type = model.Type,
CurrentWorkFlowTypeId = model.CurrentWorkFlowTypeId,
ParentBudgetId = model.ParentBudgetId
};
}
我已经阅读了很多帖子，说客户端需要完成实际传递的值，因为使用模型，只能在提交时使用（服务器端） - 但我不知道如何： （我确定我只是愚蠢而且缺少一个基本的基础来让它发挥作用。
感谢任何帮助，谢谢！
答案 0 :(得分：0)
@Ajax.ActionLink()是Razor代码，在服务器上进行解析，以便new { ... dupName = @Model.Duplicatename }在发送模型之前将dupName的值设置为属性Duplicatename的原始值到浏览器。由于文本框，它不会神奇地改变。您需要使用javascript / jquery来响应客户端事件。
如果您使用$.ajax()方法而不是Ajax.ActionLink()，这将更容易。不清楚为什么要更改默认的id属性，我建议文本框只是
@Html.TextBoxFor(m => m.Duplicatename, new { @class = "form-control", @placeholder = "Enter duplicate name" })
然后在你的循环中，创建一个链接并将项属性添加为data属性
@foreach (var item in Model.MasterBudgets)
{
if (User.IsInRole("Super Admin"))
{
<a href="#" class="duplicate btn btn-sm btn-black btn-outline" data-id="@item.BudgetId" data-type="@item.Type">Duplicate</a>
}
}
请注意附加的类名（由于重复的id属性，您之前的实现也生成了无效的html）
然后添加以下脚本
var container = $('#listofBudgets');
var url = '@Url.Action("Duplicate", "Budget")';
var textbox = $('#Duplicatename');
// handle the click event of the links
$('.duplicate').click(function() {
// get the values to be sent to the method
var id = $(this).data('id');
var type = $(this).data('type');
var name = textbox.val();
$.get(url, { id: id, type: type, dupName: name }, function(data) {
container.html(data); // update the DOM
});
});
作为旁注，您的方法应该是初始化模型并返回部分视图，而不是使用return RedirectToAction(....);
