我有一个用户可以登录的asp.net MVC网站(Visual Studio 2012,C#)。当他们单击“登录”链接时,它会打开一个jQuery对话框,该对话框呈现部分登录视图。我可以让对话框发布到正确的操作和控制器,但如果用户名/密码组合无效,我需要帮助重定向回对话框屏幕。我已经对“提交”按钮进行了错误检查,以检查在继续操作之前是否存在值,但需要有关其他部分的帮助。
我会尽力解释网站的布局:
_HeaderPartial View
<header id="header" class="style2">
<link href="@Url.Content("~/Content/themes/base/minified/jquery-ui.min.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content("~/Scripts/jquery-1.7.1.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-ui-1.8.20.min.js")" type="text/javascript"></script>
<script type="text/javascript">
var jq = jQuery.noConflict(true);
jq(document).ready(function ($) {
$("#ViewLogin").live("click", function (e) {
var url = $(this).attr('href');
$("#login_panel").dialog({
title: 'Client Login',
closeOnEscape: true,
autoOpen: false,
resizable: false,
height: 350,
width: 400,
show: { effect: 'drop', direction: "up" },
modal: true,
draggable: true,
open: function (event, ui) {
$(this).load(url);
},
close: function (event, ui) {
$(this).dialog('destroy');
}
});
$("#login_panel").dialog('open');
return false;
});
});
</script>
<div class="container">
<!-- logo -->
<h1 id="logo"><a href="@Url.Action("Index", "Home")">
<img src="~/images/small_logo.png" alt="Logo"></a></h1>
<ul class="topnav navRight">
<li> </li>
@if (Session["LoggedIn"] == null || Convert.ToBoolean(Session["LoggedIn"])==false)
{
<li><a href="@Url.Action("ViewLogin", "Home")" id="ViewLogin">LOGIN</a></li>
}
else
{
<li><a href="@Url.Action("LogOut", "Home")">LOGOUT</a></li>
}
</ul>
<other generic html markup omitted>
正如您所看到的,当单击“Login”链接时,jQuery会打开一个对话框,这是一个名为“login_panel”的简单div:
_Layout View
<div id="login_panel" style="display: none"></div>
_Login View
@model MyApp.LoginViewModel
@{
Layout = null;
}
<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>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
<div id="login_panel">
<div class="inner-container login-panel">
<h4>SIGN IN TO ACCESS YOUR ACCOUNT</h4>
@using (Html.BeginForm("Login", "Home", FormMethod.Post))
{
<div class="validation-text">
<h5>@Html.ValidationSummary()</h5>
</div>
<div>
@Html.LabelFor(x => x.Username)
@Html.TextBoxFor(x => x.Username, new { placeholder = "Username..." })
</div>
<div>
@Html.LabelFor(x => x.Password)
@Html.PasswordFor(x => x.Password, new { placeholder = "Password..." })
</div>
<br />
<button class="btn btn-danger" type="submit">LOG IN</button>
<div class="links"><a href="#" onclick="ppOpen('#forgot_panel', '350');">FORGOT YOUR USERNAME or PASSWORD?</a></div>
}
</div>
</div>
LoginViewModel
public class LoginViewModel
{
[Required(ErrorMessage = "Username is required.")]
public string Username { get; set; }
[Required(ErrorMessage = "Password is required.")]
public string Password { get; set; }
}
HomeController
public ActionResult ViewLogin()
{
return View("_Login");
}
public ActionResult LogOut()
{
Session["LoggedIn"] = false;
return RedirectToAction("Index", "Home");
}
[HttpPost]
public ActionResult Login(LoginViewModel model)
{
if (ModelState.IsValid)
{
using (ProPhysiqueContext db = new ProPhysiqueContext())
{
var user = db.Users
.Where(u => u.EmailAddress == model.Username &&
u.WebPassword == model.Password).FirstOrDefault();
if (user != null)
{
Session["LoggedIn"] = true;
return RedirectToAction("Index", "ClientStats");
}
}
}
ModelState.AddModelError("", "Invalid Username or Password.");
return PartialView("_Login", model);
}
正如您所看到的,我可以让对话框正确呈现_Login
部分视图,它将发布到Home控制器上的Login
操作。我无法弄清楚如何从Action中重新打开对话框。现在的方式是,网站重定向到主页上的_Login
部分视图,而不是对话框。
感谢任何帮助。

如何使用Ajax表单,这样您就不必费力地将视图返回到它所处的状态,即打开对话框。要做到这一点,你需要改变一些事情:
Html.BeginForm
更改为Ajax.BeginForm
并将OnComplete
属性设置为将被调用的javascript函数,接受响应的单个参数。JsonResult
,而不是RedirectToAction
结果。以下是使用您的代码的相关更改。
_Login View
@* omitted for brevity *@
@using (Ajax.BeginForm("Login", "Home", new AjaxOptions() { OnComplete = "complete" }))
{
}
<强>的HomeController 强>
[HttpPost]
public ActionResult Login(LoginViewModel model)
{
// omitted for brevity
if (user != null)
{
Session["LoggedIn"] = true;
return Json(new { url = Url.Action("Index", "ClientStats") });
}
}
HeaderPartial View
<script type="text/javascript">
var jq = jQuery.noConflict(true);
jq(document).ready(function ($) {
// omitted for brevity
});
function complete(response) {
try {
var data = JSON.parse(response.responseText);
if (data['url'])
$(location).attr('href', data['url']);
}
catch (e) {
$('#login_panel').html(response.responseText);
// this is to reapply jQuery validation to dynamic content
$.validator.unobtrusive.parse('#login_panel');
}
}
</script>
