Question

我有2页。首先我只有表格来发布搜索数据，第二个我也有相同的搜索形式和带搜索结果的容器。当我从第一个表单发布时 - 模型到搜索方法就像我预期的那样，但是从第二个表单模型属性被设置为默认值（int - 0，bool - false，string - null等）

有什么问题？

First Fom：

    <form class="form-horizontal" action="@Url.Action("Search", "Home")" method="POST">
    @Html.ValidationSummary()
    <fieldset>

        <!-- Form Name -->
        <legend>Search</legend>

        <!-- Search input-->
        <div class="form-group">
            <label class="col-md-4 control-label" for="CertID">Certificate ID</label>
            <div class="col-md-4">
                <input id="CertID" name="CertID" type="search" placeholder="Certificate ID" class="form-control input-md" required="">

            </div>
        </div>

        <!-- Search input-->
        <div class="form-group">
            <label class="col-md-4 control-label" for="CertAuthCode">Certificate AuthCode</label>
            <div class="col-md-4">
                <input id="CertAuthCode" name="CertAuthCode" type="search" placeholder="Certificate AuthCode" class="form-control input-md" required="">

            </div>
        </div>
        <div class="form-group">
            <div class="col-md-offset-4 col-md-4">
                <div class="checkbox">
                    <label>
                        <input type="checkbox" name="IncludePreviousQuestionnaire" value="true"> Include Previous Questionnaire?
                    </label>
                </div>
            </div>
        </div>

        <!-- Button -->
        <div class="form-group">
            <label class="col-md-4 control-label" for="searchCert"></label>
            <div class="col-md-4">
                <button id="searchCert" type="submit" class="btn btn-primary">Search</button>
            </div>
        </div>

    </fieldset>

第二表格：

<form class="form-horizontal" action="@Url.Action("Search", "Home")" method="POST">
@Html.ValidationSummary()
<fieldset>

    <!-- Form Name -->
    <legend>Search</legend>

    <!-- Search input-->
    <div class="form-group">
        @Html.LabelFor(m => m.SearchCertRequest.CertID, new { @class = "col-md-4 control-label" })
        @*<label class="col-md-4 control-label" for="CertID">Certificate ID</label>*@
        <div class="col-md-4">
            @Html.TextBoxFor(m => m.SearchCertRequest.CertID, new { @placeholder = "Certificate ID", @class = "form-control input-md", @required="required" })
            @*<input id="CertID" name="SearchCertRequest.CertID" type="search" placeholder="Certificate ID" class="form-control input-md" required="">*@
            @Html.ValidationMessageFor(m => m.SearchCertRequest.CertID)
        </div>
    </div>

    <!-- Search input-->
    <div class="form-group">
        @Html.LabelFor(m => m.SearchCertRequest.CertAuthCode, new { @class = "col-md-4 control-label" })
        @*<label class="col-md-4 control-label" for="CertAuthCode">Certificate AuthCode</label>*@
        <div class="col-md-4">
            @Html.TextBoxFor(m => m.SearchCertRequest.CertAuthCode, new { @placeholder = "Certificate AuthCode", @class = "form-control input-md", @required = "required" })
            @*<input id="CertAuthCode" name="SearchCertRequest.CertAuthCode" type="search" placeholder="Certificate AuthCode" class="form-control input-md" required="">*@
            @Html.ValidationMessageFor(m => m.SearchCertRequest.CertAuthCode)
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-offset-4 col-md-4">
            <div class="checkbox">
                <label>
                    @Html.CheckBoxFor(m=>m.SearchCertRequest.IncludePreviousQuestionnaire)
                    @*<input type="checkbox" name="SearchCertRequest.IncludePreviousQuestionnaire">*@ Include Previous Questionnaire?
                </label>
            </div>
        </div>
    </div>

    <!-- Button -->
    <div class="form-group">
        <label class="col-md-4 control-label" for="searchCertBtn"></label>
        <div class="col-md-4">
            <button id="searchCertBtn" name="searchCertBtn" type="submit" class="btn btn-primary">Search</button>
        </div>
    </div>

</fieldset>

搜索请求模型：

 public class SearchCertRequest
{
    [Required]
    public long CertID { get; set; }
    [Required]
    public string CertAuthCode { get; set; }
    public bool IncludePreviousQuestionnaire { get; set; }
}

更新：第二个表格的模型存在于下一个表格中：

public class SearchViewModel
    {
        public SearchCertModel CertModel { get; set; } // Serch Result
        public SearchCertRequest SearchCertRequest { get; set; } // Search Request
    }

已解决：我从搜索表单中创建了部分视图，现在它正在运行。有人可以解释一下原因吗？感谢。

Answer 1

两种形式都回发到同一种方法（家庭控制器的搜索方法）。首先是工作签名必须是

[HttpPost]
public ActionResult (SearchCertRequest model)
{

但第二种形式是为SearchViewModel生成控件，因此签名必须是

[HttpPost]
public ActionResult (SearchViewModel model)
{

修改

在编辑中解释评论。第二种形式是您的生成控件，例如<input name="SearchCertRequest.CertID" ...>。当您创建部分视图并将SearchCertRequest属性SearchViewModel传递给它时，它会生成<input name="CertID" ...>等控件，这些控件将正确地回发到public ActionResult (SearchCertRequest model)

Post Model始终为空
