局部视图不调用 Http Post 方法

Question

所以我在我的主页上创建了一个部分登录。表单可以正确呈现，但是每当我提交表单时它都不会调用 http post 操作结果。请参阅下面的代码以供参考。

主页：

<header class="navbar sticky-top navbar-expand-lg navbar-dark bg-dark">
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarTogglerDemo01">


        <ul class="navbar-nav mr-auto mt-2 mt-lg-0">
            <li class="nav-item active">
                <a href="@Url.Action("HomePage", "Home")" class="nav-link">HOME</a>
            </li>
            <li class="nav-item">
                <a href="@Url.Action("Branchlist", "Branch")" class="nav-link">BRANCH</a>
            </li>
        </ul>
        <form class="form-inline my-2 my-lg-0">
            <div> @{Html.RenderAction("LogInBox");}</div>>
        </form>
    </div>
</header>

}

HomeController.cs

    public ActionResult LogInBox()

    {
        return View();
    }


    [HttpPost]

            if (ua != null)
            {
                string ep = eh.GetEncrypted(acn.Password, acn.Username);

                if (ua.Password == ep && ua.Type != "") // Needs to Identify the type of Account(Client/Admin) Otherwise Cannot Login
                {

                    Session["ActiveUser"] = ua.UserId;

                    if (ua.Type == "Admin" || ua.Type == "SuperUser")
                    {
                        return RedirectToAction("Index", "Maintenance");
                    }
                    else
                    {
                        return RedirectToAction("Index", "Profile");
                    }
                }
                else
                {
                    ViewBag.Message = "Incorrect Password!";

                    return View();
                }
            }
            else
            {
                ViewBag.Message = "Invalid Account!";

                return View();
            }
        }
        else
        {
            return View();
        }
    }

提交时不调用ActionResult LogInBox(LoyaltyAccountModel acn)

请帮忙。它总是调用第一个 ActionResult，即不带参数的那个。

由于您在 Home 中有表单标签，而在部分中有另一个表单标签，这会在运行时生成嵌套表单，这是不受支持的。

从下面的代码中删除表单标签。

<form class="form-inline my-2 my-lg-0">
            <div> @{Html.RenderAction("LogInBox");}</div>>
</form>
