Question

我有一个获取用户名和密码的视图，需要将其传递给数据库。我可以传递用户名而不是密码。

查看：

<div class="form-group">
    @Html.LabelFor(m => m.UserName, new { @class = "label-control" })
    @Html.PasswordFor(m => m.UserName, new { @class = "form-control", autofocus = "", value = "Text" })
    @Html.ValidationMessageFor(m => m.UserName, null, new { @class = "alert-danger" })
</div>
<div class="form-group">
    @Html.LabelFor(m => m.Password, new { @class = "label-control" })
    @Html.TextBoxFor(m => m.Password, new { @class = "form-control" })
    @Html.ValidationMessageFor(m => m.Password, null, new { @class = "alert-danger" })
</div>

控制器：

public ActionResult EditUserSubmit(string UserName, string Password, string ProcessType)
{
    string process;
    string name = Url.RequestContext.RouteData.Values["id"].ToString();
    process = (ProcessType == "Processed") ? "P" : "B";
    DB.Entities.user users = db.users.Where(m => m.username == name).FirstOrDefault();
    users.password = Password;
    users.processtype = process;
    db.SaveChanges();

    return RedirectToAction("Manager");
}

更新

这是整个视图

@model NV.Tax.SST.Gateway.MVC.Models.AdministrationModel
@{string name = Url.RequestContext.RouteData.Values["id"].ToString();}

<div class="x-form-wrapper">
    <div class="x-form-title">
        <h3><strong>User Detail for <b>@Url.RequestContext.RouteData.Values["id"]</b></strong></h3>
    </div>
    <div class="x-form-body">
        <div class="form-group">
            @Html.LabelFor(m => m.UserName, new { @class = "label-control" })
            @Html.TextBoxFor(m => m.UserName, new { @class = "form-control", autofocus = "", value = "Text" })
            @Html.ValidationMessageFor(m => m.UserName, null, new { @class = "alert-danger" })
        </div>
        <div class="form-group">
            @Html.LabelFor(m => m.Password, new { @class = "label-control" })
            @Html.PasswordFor(m => m.Password, new { @class = "form-control" })
            @Html.ValidationMessageFor(m => m.Password, null, new { @class = "alert-danger" })
        </div>
        <div class="form-group">
            @Html.LabelFor(m => m.ProcessType, new { @class = "label-control" })
            @Html.DropDownListFor(m => m.ProcessType, new[]{
                    new SelectListItem { Text = "Processed", Value = "Processed" },
                    new SelectListItem { Text = "Both", Value = "Both" }
                }, new { @class = "form-control" })
            @Html.ValidationMessageFor(m => m.ProcessType, null, new { @class = "alert-danger" })
        </div>
        <div class="form-group">
            <a href="/Administration/EditUserSubmit/@name" class="btn btn-lg btn-primary">Save</a>
            @Html.ActionLink("Cancel", "Manager", "Administration", null, new { @class = "btn btn-lg btn-default" })
        </div>
    </div>
</div>
@{
    string password = "";
    var entity = new NV.Tax.SST.Gateway.DB.Entities.sstpEntities();
    var data = from db in entity.users
                where db.username == name
                select db;
    foreach(var item in data)
    {
        password = item.password;
        <script>document.getElementById("Password").defaultValue = "@password"</script>
        if (item.processtype == "B")
        {
            <script>document.getElementById("ProcessType").value = "Both"</script>
        }
        else
        {
            <script>document.getElementById("ProcessType").value = "Processed"</script>
        }
    }

}

Answer 1

因为您正在创建像这样的密码文本框

@Html.TextBoxFor(m => m.Password, new { @class = "form-control" })

很明显，您使用的是具有UserName和Password属性的视图模型类。我猜它还有ProcessType属性。由于您在视图顶部具有以下语法

@model NV.Tax.SST.Gateway.MVC.Models.AdministrationModel

您可以使用NV.Tax.SST.Gateway.MVC.Models.AdministrationModel作为控制器操作方法的参数，如下所示

public ActionResult EditUserSubmit(NV.Tax.SST.Gateway.MVC.Models.AdministrationModel model)
{
    string process;
    string name = Url.RequestContext.RouteData.Values["id"].ToString();
    process = (model.ProcessType == "Processed") ? "P" : "B";
    DB.Entities.user users = db.users.Where(m => m.username == name).FirstOrDefault();
    users.password = model.Password;
    users.processtype = process;
    db.SaveChanges();

    return RedirectToAction("Manager");
}

model.Password的值将是您在密码文本框中输入的内容。

修改

查看整个视图代码后，这就是你错了

<a href="/Administration/EditUserSubmit/@name" class="btn btn-lg btn-primary">Save</a>

您无法使用锚标记并且没有<form>标记来提交网页。您需要在其中包含<form>标记和提交按钮。可以使用<form>辅助方法生成Html.BeginForm标记。将您的观看代码更改为以下

@model NV.Tax.SST.Gateway.MVC.Models.AdministrationModel @{string name = Url.RequestContext.RouteData.Values["id"].ToString();} <div class="x-form-wrapper"> <div class="x-form-title"> <h3><strong>User Detail for <b>@Url.RequestContext.RouteData.Values["id"]</b></strong></h3> </div> <div class="x-form-body"> @using (Html.BeginForm("EditUserSubmit", "Administration")) { <div class="form-group"> @Html.LabelFor(m => m.UserName, new { @class = "label-control" }) @Html.TextBoxFor(m => m.UserName, new { @class = "form-control", autofocus = "", value = "Text" }) @Html.ValidationMessageFor(m => m.UserName, null, new { @class = "alert-danger" }) </div> <div class="form-group"> @Html.LabelFor(m => m.Password, new { @class = "label-control" }) @Html.PasswordFor(m => m.Password, new { @class = "form-control" }) @Html.ValidationMessageFor(m => m.Password, null, new { @class = "alert-danger" }) </div> <div class="form-group"> @Html.LabelFor(m => m.ProcessType, new { @class = "label-control" }) @Html.DropDownListFor(m => m.ProcessType, new[]{ new SelectListItem { Text = "Processed", Value = "Processed" }, new SelectListItem { Text = "Both", Value = "Both" } }, new { @class = "form-control" }) @Html.ValidationMessageFor(m => m.ProcessType, null, new { @class = "alert-danger" }) </div> <div class="form-group"> <button type="submit" class="btn btn-lg btn-primary">Save</button> @Html.ActionLink("Cancel", "Manager", "Administration", null, new { @class = "btn btn-lg btn-default" }) </div> } </div> </div> @{ string password = ""; var entity = new NV.Tax.SST.Gateway.DB.Entities.sstpEntities(); var data = from db in entity.users where db.username == name select db; foreach(var item in data) { password = item.password; <script>document.getElementById("Password").defaultValue = "@password"</script> if (item.processtype == "B") { <script>document.getElementById("ProcessType").value = "Both"</script> } else { <script>document.getElementById("ProcessType").value = "Processed"</script> } } }

您还应添加[HttpPost]属性并更改控制器操作方法，如下所示

[HttpPost] public ActionResult EditUserSubmit(NV.Tax.SST.Gateway.MVC.Models.AdministrationModel model) { string process = (model.ProcessType == "Processed") ? "P" : "B"; DB.Entities.user users = db.users.Where(m => m.username == model.UserName).FirstOrDefault(); users.password = model.Password; users.processtype = process; db.SaveChanges(); return RedirectToAction("Manager"); }

如何将Html.Password帮助程序的值传递给Action
