验证发生在视图加载之前

Question

好吧，事情就是这样。我有一个简单的登录屏幕（在单独的区域中），当我在菜单中选择“登录”时，登录屏幕会完美加载，但它会显示错误，例如简单地加载视图即可执行验证（不显眼的 jQuery）。

这是登录页面的链接：

<li> <%: Html.ActionLink("Log In", "Index", "Login", new { area = "AdminArea" }, null)%></li>

这是登录视图：

<%= Html.RenderScript("MicrosoftMvcJQueryValidation")%>
<%= Html.RenderScript("json2")%>
<%= Html.RenderScript("loginForm")%>
<%  Html.EnableClientValidation(); %>

<% using (Html.BeginForm("Index", "Login", FormMethod.Post, new { @id = "signin" }))
{
    ViewContext.FormContext.ValidationSummaryId = "valLoginContainer"; %>
<fieldset>
<div class="row">
    <span class="label">
        <label for="Password">&nbsp;</label>
    </span>
    <table style="width" border="none;">
        <tr>
            <td>
                <%= Html.JQueryValidationSummary("Please fix the following error(s):", new Dictionary<string, object> { { "id", "valLoginContainer" } })%>
            </td>
        </tr>
    </table>
</div>
<legend>Admin Login</legend>
<div class="row">
    <span class="label">
        <label for="Username">Username:</label>
    </span>
    <%= Html.TextBoxFor(m=> m.Username, new { @class = "inputbox" })%><%= Html.ValidationMessageFor(m => m.Username, " *")%>
</div>
<div class="row">
    <span class="label">
        <label for="Password">Password:</label>
    </span>
    <%= Html.TextBoxFor(m=> m.Password, new { @class = "inputbox" })%><%= Html.ValidationMessageFor(m => m.Password, " *")%>
</div>
<div class="row">
    <span class="label">
        <label for="Password">&nbsp;</label>
    </span><a href="#" id="forgot_password_link" title="Click here to reset your password."> Forgot password?</a>
</div>
<div class="row">
    <span class="label">
        <label for="Password">&nbsp;</label>
    </span>
    <a href="#" id="forgot_username_link" title="Fogot your login name? We can help with that"> Forgot username?</a>
</div>
    <div class="row">
    <span class="label">
        <label for="Password">&nbsp;</label>
    </span>
    <input type="submit" id="action" value="Submit &raquo;" class="formButtons" />
</div>
</fieldset>
<%}%>

有人知道为什么在视图加载时执行验证吗？

Answer 1

这个问题已经解决了。我丢失了一个 JS 文件（我不知道），一旦添加该文件，一切都会正常工作。另外，在 LoginController.cs 中，我有这一行是不正确的，

public virtual ActionResult Index()
{
    return View();
}

一旦我将其更改为“一切都很好”，

public virtual ActionResult Index()
{
    return View(new LoginViewModel());
}

LoginViewModel 看起来像这样：

public class LoginViewModel
{
    [Required(ErrorMessage = "Username/email is required")]
    public string Username { get; set; }

    [Required(ErrorMessage = "Password is required")]
    public string Password { get; set; }

    public bool RememberMe { get; set; }
}

感谢所有查看它的人。
