我有一个视图,其中有几个部分视图,我绑定到我的模型。出于某种原因,当我发布时,模型是空的,我不知道为什么。
以下是我的ViewModel。
public class IndexViewModel
{
public bool AdvancedSearchOption { get; set; }
public bool ForceAdvanced { get; set; }
public bool ForceSimple { get; set; }
public string SimpleSearchCriteria { get; set; }
public string CustomerNumberCriteria { get; set; }
public string AccountNumberCriteria { get; set; }
public string NameCriteria { get; set; }
public string PhoneNumberCriteria { get; set; }
}
这是我的控制器。我正在填写视图模型的所有值,因为我想查看值是否到达部分视图。他们确实到了那里,所以只是在帖子上我有问题。
public class HomeController : Controller
{
private ISecurityRepository SecurityRep;
public HomeController(ISecurityRepository repo)
{
SecurityRep = repo;
}
public ActionResult Index()
{
IndexViewModel temp = new IndexViewModel();
temp.AdvancedSearchOption = SecurityRep.DefaultToAdvancedSearch(User.Identity.Name);
temp.ForceAdvanced = false;
temp.ForceSimple = false;
temp.SimpleSearchCriteria = "Testing";
temp.AccountNumberCriteria = "Acct";
temp.CustomerNumberCriteria = "Cust";
temp.NameCriteria = "Name";
temp.PhoneNumberCriteria = "Phone";
return View(temp);
}
public ActionResult SimpleSearch()
{
IndexViewModel temp = new IndexViewModel();
temp.AdvancedSearchOption = SecurityRep.DefaultToAdvancedSearch(User.Identity.Name);
temp.ForceAdvanced = false;
temp.ForceSimple = true;
temp.SimpleSearchCriteria = "Testing";
temp.AccountNumberCriteria = "Acct";
temp.CustomerNumberCriteria = "Cust";
temp.NameCriteria = "Name";
temp.PhoneNumberCriteria = "Phone";
return View("Index",temp);
}
public ActionResult AdvancedSearch()
{
IndexViewModel temp = new IndexViewModel();
temp.AdvancedSearchOption = SecurityRep.DefaultToAdvancedSearch(User.Identity.Name);
temp.ForceAdvanced = true;
temp.ForceSimple = false;
temp.SimpleSearchCriteria = "Testing";
temp.AccountNumberCriteria= "Acct";
temp.CustomerNumberCriteria= "Cust";
temp.NameCriteria= "Name";
temp.PhoneNumberCriteria = "Phone";
return View("Index", temp);
}
[HttpPost]
public ActionResult Index(IndexViewModel vm, FormCollection formCollection)
{
return View();
}
}
这是我的观点
@model TRIOSoftware.Magnum.Models.IndexViewModel
@{
ViewBag.Title = "Search";
}
@if ((@Model.AdvancedSearchOption && @Model.ForceSimple != true) || @Model.ForceAdvanced == true)
{
@Html.Partial("AdvancedSearch")
}
else
{
@Html.Partial("SimpleSearch")
}
这是我的SimpleSearch
部分视图。我想如果我能让这个工作,另一个将遵循相同的道路。我在局部发帖,我用jQuery来做。我不确定这些事情中的任何一个是否会引起我的问题。我只有所有隐藏的物品,因为我不知道是否没有它们导致我的问题。
@model TRIOSoftware.Magnum.Models.IndexViewModel
<script type="text/javascript">
$(document).ready(function () {
$("#DefaultDiv").find("#DefaultAdvanced").click(function () {
$.post("DefaultSimple");
});
$("#SearchSection").find("#SearchButton").click(function () {
$.post("");
});
});
</script>
@using (Html.BeginForm("Index","Home"))
{
@Html.HiddenFor(m => m.ForceAdvanced)
@Html.HiddenFor(m => m.AdvancedSearchOption)
@Html.HiddenFor(m => m.ForceSimple)
@Html.HiddenFor(m => m.AccountNumberCriteria)
@Html.HiddenFor(m => m.CustomerNumberCriteria)
@Html.HiddenFor(m => m.NameCriteria)
@Html.HiddenFor(m => m.PhoneNumberCriteria)
<div id="DefaultDiv" style="float:right">
<a id="DefaultAdvanced" href="#" class="ButtonClass">Default Simple Search</a>
</div>
<div style="clear:both; margin: auto; width: 800px">
<img src="../../Content/images/TRIO_transparent_image.gif"; alt="TRIO Software"; style="margin-left:150px; clear:left"/>
<div style="clear:left; float: left" class="SearchText">
@Html.Label("What's your inquiry?:")
@Html.EditorFor(m => m.SimpleSearchCriteria, new { style = "width: 400px" })
</div>
<div id="SearchSection" style="float: left" class="SearchText">
<a href="#"; id="SearchButton" class="ButtonClass"><img src="../../Content/images/Search.gif"; alt="Search"; style="float:left" /></a>
</div>
<p style="clear:left;margin-left:400px">
@Html.ActionLink("Advanced Search", "AdvancedSearch", null, new { style = "clear:left" })
</p>
</div>
}
以下是查看简单搜索部分视图时的HTML代码:
<div id="main">
<script type="text/javascript">
$(document).ready(function () {
$("#DefaultDiv").find("#DefaultAdvanced").click(function () {
$.post("DefaultSimple");
});
$("#SearchSection").find("#SearchButton").click(function () {
$.post("");
});
});
</script>
<form method="post" action="/">
<input type="hidden" value="False" name="ForceAdvanced" id="ForceAdvanced" data-val-required="The ForceAdvanced field is required." data-val="true">
<input type="hidden" value="False" name="AdvancedSearchOption" id="AdvancedSearchOption" data-val-required="The AdvancedSearchOption field is required." data-val="true">
<input type="hidden" value="False" name="ForceSimple" id="ForceSimple" data-val-required="The ForceSimple field is required." data-val="true">

</div>
<p style="clear:left;margin-left:400px">

如何解决此问题?

虽然您选择了部分渲染,但您没有将模型传递给它。有一个Html.Partial
的重载版本,它带有第二个参数,允许你将模型传递给它:
@Html.Partial("ViewName", Model);
所以在你的情况下,你会使用它:
@if ((Model.AdvancedSearchOption && Model.ForceSimple != true) || Model.ForceAdvanced == true)
{
@Html.Partial("AdvancedSearch", Model)
}
else
{
@Html.Partial("SimpleSearch", Model)
}
另请注意我是如何删除@
前缀为Model
的{{1}}。为了更好地理解原因,请参阅Introduction to ASP.NET Web Programming Using the Razor Syntax以及由Phil Haack撰写的同一主题的小参考here。

我认为@ john-h用他的答案击中了头部。但是,您可能希望降低为自己创建的复杂性。
1)由于ForceSimple和ForceAdvanced都是布尔值,因此假设当ForceAdvanced为真时,它不是“简单”,对吧?我不确定你在这里有什么其他的逻辑。
2)为什么不使用参数来设置搜索类型,而不是创建两个视图并“回发”以获取正确的视图?或者评估安全性以设置用户可以执行的安全性。这是一个例子:
控制器操作:
//id is the search type: true is Advanced
public ActionResult Search(bool id) {
IndexViewModel viewModel = new IndexViewModel {
/* Do whatever logic here */
ForceAdvanced = (id) ? false : true,
AdvancedSearchOption = id
};
return View("search", viewModel);
}
[HttpPost]
public ActionResult Search(IndexViewModel model) {
//model.SimpleSearchCriteria = "Testing";
//model.PhoneNumberCriteria = "Phone";
return View("search", model);
}
搜索视图:
@using (@Html.BeginForm(new { id = @Model.AdvancedSearchOption })) {
<div style="clear:left; float: left" class="SearchText">
@Html.Label("What's your inquiry?:")
@if (Model.AdvancedSearchOption) {
<div>
@* if you really want, load your partial views here *@
<span>@Html.LabelFor(m => m.NameCriteria)</span>
@Html.EditorFor(m => m.NameCriteria, new { style = "width: 400px" })
<span>@Html.LabelFor(m => m.PhoneNumberCriteria)</span>
@Html.EditorFor(m => m.PhoneNumberCriteria, new { style = "width: 400px" })
</div>
}
else {
@* if you really want, load your partial views here *@
@Html.EditorFor(m => m.SimpleSearchCriteria, new { style = "width: 400px" })
}
</div>
<div>
<input type="submit" value="Search" />
</div>
@Html.HiddenFor(m => m.ForceAdvanced)
@Html.HiddenFor(m => m.AdvancedSearchOption)
@Html.HiddenFor(m => m.ForceSimple)
@Html.HiddenFor(m => m.AccountNumberCriteria)
@Html.HiddenFor(m => m.CustomerNumberCriteria)
@Html.HiddenFor(m => m.NameCriteria)
@Html.HiddenFor(m => m.PhoneNumberCriteria)
}

我曾尝试明确地将模型发送给部分人,但没有运气。我相信如果没有指定任何内容,部分视图默认获取父模型,所以我需要做的就是在我的部分中指定模型类型,我得到了信息。
我终于通过大量的反复试验弄明白了。我的问题是由于我尝试使用jQuery来发帖。您需要做一些其他事情来更新模型,这样做。一旦我将其更改并在帖子的表单上放置了一个输入控件,我就从控制器中的父视图和部分视图中获取了所有数据。
