c# - 无法使ASP.NET MVC客户端验证正常工作

实际上，我已经在ASP.NET MVC应用程序模板（随VS提供）中复制了“登录”页面的代码。在原始模板中，客户端验证有效，但是当我复制所有连接的代码时，我仅获得服务器端验证（没有红色字段，即使数据不正确也要发回）。

这是我的模型代码：

public class LogOnModel {
    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [Display(Name = "Remember me?")]
    public bool RememberMe { get; set; }
}


这是控制器：

public class LogOnController : Controller
{
    public ActionResult Index() {
        return View();
    }

    [HttpPost]
    public ActionResult Index(LogOnModel model)
    {
        if (ModelState.IsValid) {
            return RedirectToAction("Index", "Games");
        }

        return View(model);
    }
}


这是视图：

<%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage<PuzzleHunter.Web.Models.LogOnModel>" MasterPageFile="~/Views/Shared/SiteMasterPage.master" %>
<asp:Content runat="server" ID="Content" ContentPlaceHolderID="MainContent">

<script src="<%: Url.Content("~/Scripts/jquery.validate.min.js") %>" type="text/javascript"></script>
<script src="<%: Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js") %>" type="text/javascript"></script>

<% using (Html.BeginForm()) { %>
    <%: Html.ValidationSummary(true, "Login was unsuccessful. Please correct the errors and try again.") %>
    <div>
        <fieldset>
            <legend>Account Information</legend>
            <div class="editor-label">
                <%: Html.LabelFor(m => m.UserName) %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(m => m.UserName) %>
                <%: Html.ValidationMessageFor(m => m.UserName) %>
            </div>

            <div class="editor-label">
                <%: Html.LabelFor(m => m.Password) %>
            </div>
            <div class="editor-field">
                <%: Html.PasswordFor(m => m.Password) %>
                <%: Html.ValidationMessageFor(m => m.Password) %>
            </div>

            <div class="editor-label">
                <%: Html.CheckBoxFor(m => m.RememberMe) %>
                <%: Html.LabelFor(m => m.RememberMe) %>
            </div>
            <p>
                <input type="submit" value="Log On" />
            </p>
        </fieldset>
    </div>
<% } %>




我的Web.config文件中还有以下几行：

<appSettings>
    <add key="ClientValidationEnabled" value="true"/>
    <add key="UnobtrusiveJavaScriptEnabled" value="true"/>
</appSettings>

为了进行比较，这是客户端验证有效的VS MVC模板的输出：

    <!DOCTYPE html>
    <html>
    <head><title>

        </title><link href="../Content/Site.css" rel="stylesheet" type="text/css" />

    <body>
        <div class="page">

            <div id="main">
        <script src="/Scripts/jquery.validate.min.js" type="text/javascript"></script>
        <script src="/Scripts/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>

        <form action="/Account/LogOn" method="post">
            <div>
                <fieldset>
                    <legend>Account Information</legend>

                    <div class="editor-label">
                        <label for="UserName">User name</label>

                        <input data-val="true" data-val-required="The User name field is required." id="UserName" name="UserName" type="text" value="" />
                        <span class="field-validation-valid" data-valmsg-for="UserName" data-valmsg-replace="true"></span>
                    </div>

                    <div class="editor-label">
                        <label for="Password">Password</label>
                    </div>
                    <div class="editor-field">

                    <div class="editor-label">

                        <label for="RememberMe">Remember me?</label>
                    </div>

                    <p>
                        <input type="submit" value="Log On" />
                    </p>
                </fieldset>

        </form>
            </div>
        </div>
    </body>
    </html>

最佳答案

您需要在FORM开始之前添加以下内容：

<% Html.EnableClientValidation();%>


另外，请确保已引用此脚本：

<script src="<%=Url.Content("~/Scripts/MicrosoftMvcJQueryValidation.js")%>"


以及jQuery本身。
