asp.net MVC 4经由不同的形式的多个交(asp.net MVC 4 multiple po

现在我明白了

if (IsPost){   //do stuff }

检查该网页上的所有岗位的方法。但是，我有2种不同的形式发布2个不同的信息。这是一个登录表单和登记表。

有没有一种方法，我可以根据其形态上的检查IsPost？例如，

if(Login.IsPost){ //do stuff }

但我会如何定义登录变量？我的形式是这样的：

<form id="Login" method = "POST">

我试过了：

var Login = Form.["Login"]

那没起效。

我感谢所有帮助。

谢谢。

Answer 1:

在一个MVC视图，因为你需要，你可以有尽可能多的领域尽可能多的形式。为了保持它的简单，用一个单一的视图模型，你需要在页面上每一个表格的所有属性。请记住，你将只能访问从表单，您提交表单字段数据。所以，如果你有相同的页面上的登录表单，并登记表，你会做这样的：

LoginRegisterViewModel.cs

public class LoginRegisterViewModel {
    public string LoginUsername { get; set; }
    public string LoginPassword { get; set; }

    public string RegisterUsername { get; set; }
    public string RegisterPassword { get; set; }
    public string RegisterFirstName { get; set; }
    public string RegisterLastName { get; set; }
}

YourViewName.cshtml

@model LoginRegisterViewModel

@using (Html.BeginForm("Login", "Member", FormMethod.Post, new {})) {

    @Html.LabelFor(m => m.LoginUsername)
    @Html.TextBoxFor(m => m.LoginUsername)

    @Html.LabelFor(m => m.LoginPassword)
    @Html.TextBoxFor(m => m.LoginPassword)

    <input type='Submit' value='Login' />

}

@using (Html.BeginForm("Register", "Member", FormMethod.Post, new {})) {

    @Html.LabelFor(m => m.RegisterFirstName)
    @Html.TextBoxFor(m => m.RegisterFirstName)

    @Html.LabelFor(m => m.RegisterLastName)
    @Html.TextBoxFor(m => m.RegisterLastName)

    @Html.LabelFor(m => m.RegisterUsername)
    @Html.TextBoxFor(m => m.RegisterUsername)

    @Html.LabelFor(m => m.RegisterPassword)
    @Html.TextBoxFor(m => m.RegisterPassword)

    <input type='Submit' value='Register' />

}

MemberController.cs

[HttpGet]
public ActionResult LoginRegister() {
     LoginRegisterViewModel model = new LoginRegisterViewModel();
     return view("LoginRegister", model);
}

[HttpPost]
public ActionResult Login(LoginRegisterViewModel model) {
 //do your login code here
}

[HttpPost]
public ActionResult Register(LoginRegisterViewModel model) {
 //do your registration code here
}

不要忘了，在调用时BeginForm，你通过控制器名称没有“控制器”附：

@using (Html.BeginForm("Login", "Member", FormMethod.Post, new {}))

代替：

@using (Html.BeginForm("Login", "MemberController", FormMethod.Post, new {}))

Answer 2:

我刚加载（含有一种形式）的局部视图为每个所需的形式，给每个部分不同的视图模型：

多形上一个页面，要求：满足。
每份表格上不显眼的Javascript验证：完成。

Answer 3:

你应该让每个<form>点都有自己的模型参数的单独行动。

Answer 4:

而不是做一个表单提交的，我们可以做相应的提交按钮的点击一个ajax开机自检。

@using (Html.BeginForm("ActionName", "ControllerName", FormMethod.Post, new { @Id = "Form1" }))
{

}

@using (Html.BeginForm("ActionName", "ControllerName", FormMethod.Post, new { @Id = "Form2" }))
{

}

一旦你分配不同的id属性给每个在你的页面的形式，使用这样的代码：

$(document).ready( function() {
  var form = $('#Form1');

 $('#1stButton').click(function (event) {

    $.ajax( {
      type: "POST",
      url: form.attr( 'action' ),
      data: form.serialize(),
      success: function( response ) {
        console.log( response );
      }
    } );
  } );
}

重复2日按钮的Click事件同样的事情援引第二形式阿贾克斯后。

此代码使用.serialize（）从形式拉出相关数据。

对于未来的参考， jQuery的文档是非常，非常好。

注意：您使用的触发，导致通过AJAX后表单的提交事件的按钮不应该的类型提交！否则，这将总是失败。

Answer 5:

Use this example to prevent unnecessary/unintended validation checks while using multiple Form Post with different Controller Actions.

要找什么

本质上，这代码利用该模型标志该控制器动作被称为在表单提交的布尔内。
注意这里使用了嵌套模式和[是行动登录]和[是行动注册]布尔属性，我使用方法帮助IsActionLogin（）和IsActionRegister（）设置。只有一个将在各自控制器动作被调用。

请注意，在模型中sReturnURL财产。此属性存储一个导航网址，并与登录和注册控制器动作共享。这将使我们返回到用户离开该页面不必登录之前。

 /* Begin Model logic */ public class LoginRegisterModel { public LoginModel LoginModel { get; set; } public RegisterModel RegisterModel { get; set; } public string sReturnURL { get; set; } public bool bIsActionLogin { get; set; } public bool bIsActionRegister { get; set; } public void IsActionLogin() { bIsActionLogin = true; bIsActionRegister = false; } public void IsActionRegister() { bIsActionLogin = false; bIsActionRegister = true; } } public class LoginRegisterModel { public LoginModel LoginModel { get; set; } public RegisterModel RegisterModel { get; set; } public string sReturnURL { get; set; } public bool bIsActionLogin { get; set; } public bool bIsActionRegister { get; set; } public void IsActionLogin() { bIsActionLogin = true; bIsActionRegister = false; } public void IsActionRegister() { bIsActionLogin = false; bIsActionRegister = true; } } public class RegisterModel { [Required] [Display(Name = "Email")] [RegularExpression("^[a-zA-Z0-9_\\.-]+@([a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$", ErrorMessage = "Email is not valid.")] public string UserName { get; set; } [Required] [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [Required] [DataType(DataType.Password)] [Display(Name = "Confirm Password")] [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")] public string ConfirmPassword { get; set; } } /*End Model logic*/ /*Begin Controller Logic*/ [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public ActionResult Login(LoginRegisterModel model, string sReturnURL) { model.IsActionLogin(); //flags that you are using Login Action //process your login logic here } [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public ActionResult Register(LoginRegisterModel model, string sReturnURL) { model.IsActionRegister(); //flag Action Register action //process your register logic here } /*End Controller Logic*/ /*Begin View Logic*/ @model eCommerce.Models.LoginRegisterModel @{ /*Place this view logic in both the Login.cshtml and Register.cshtml.
