提醒Javascript作为返回响应的操作

Question

我怎么能做,例如,我在users.cshtml视图中创建一个用户,它验证ActionResult创建(RegisterModel嗯),如果一切正常,我想返回users.cshtml但总是有一个javascript警报或类似,具有来自动作的变量的值.我可以这样做吗？

在我看来,我有这个...

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)

<fieldset>
    <legend>Crear Usuario</legend>

     <div class="editor-label">
        Username:
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(model => model.UserName)
        @Html.ValidationMessageFor(model => model.UserName)
    </div>

    <div class="editor-label">
        Password:
    </div>
    <div class="editor-field">
        @Html.PasswordFor(model => model.Password)
        @Html.ValidationMessageFor(model => model.Password)
    </div>

            <div class="editor-label">
        Repite Password:
    </div>
    <div class="editor-field">
        @Html.PasswordFor(model => model.ConfirmPassword)
        @Html.ValidationMessageFor(model => model.ConfirmPassword)
    </div>
    </div>
    <p>
        <input type="submit" value="Crear" />
    </p>
</fieldset>

这在我的控制器动作..

public ActionResult Create(RegisterModel um)
{

    if (um.Password == um.ConfirmPassword)
    {
        // Attempt to register the user
        MembershipCreateStatus createStatus;
        Membership.CreateUser(um.UserName, um.Password, um.Email, um.PasswordAnswer, um.PasswordQuestion, true, null, out createStatus);

        if (createStatus == MembershipCreateStatus.Success)
        {
            var alert = MembershipCreateStatus.Success.ToString();
        }
        else
        {
            ModelState.AddModelError("", ErrorCodeToString(createStatus));

            var alert = ErrorCodeToString(createStatus);
        }
    }
        //HERE IS WHERE I WANT TO RETURN TO /ADMIN/USERS BUT WITH AN ALERT WITH CONTAINING THE VALUE OF alert IN A JAVASCRIPT OR SIMILAR ALERT WINDOW

    return RedirectToAction("Users", "Admin"); ???????

我可以这样做吗？

您可以TempData在重定向到Users操作之前将消息存储在内部:

TempData["message"] = "some message that you want to display";
return RedirectToAction("Users", "Admin");

然后在Users.cshtml视图内部(由Users您重定向的操作返回)测试是否存在此消息并显示alert:

@if (TempData["message"] != null) {
    <script type="text/javascript">
        alert(@Html.Raw(Json.Encode(TempData["message"])));
    </script>
}
