我有一个使用模态引导的部分视图登录。在客户端验证了模型后，所有工作都正常。但是我想检查登录是否失败，如果是，请将错误消息从控制器返回到模态引导，而不是返回页面。我怎样才能做到这一点？如何从控制器进行模态引导验证？
我_partialview登录：
<div id="loginModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">
@using (Html.BeginForm("Login", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal"}))
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(m => m.Email, new { @class = "col-md-2 control-label" })
<div class="col-md-10">
@Html.TextBoxFor(m => m.Email, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.Email, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(m => m.Password, new { @class = "col-md-2 control-label" })
<div class="col-md-10">
@Html.PasswordFor(m => m.Password, new { @class = "form-control" })
@Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" })
</div>
</div>
<div style="text-align:right;">
<button type="submit" class="btn btn-primary btn-sm">Submit</button>
</div>
}
</div>
</div>
账户控制器
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
if (!ModelState.IsValid)
{
return View(model);
}
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
switch (result)
{
case SignInStatus.Failure:
default:
ModelState.AddModelError("", "Invalid login attempt.");
return View(model);
}
}
