使用 jquery ajax 序列化的模型绑定不起作用

Model binding with jquery ajax serialize not working

提问by mosquito87

I have the following model:

我有以下模型：

public class RegisterUseraccount
{
    [Required]
    [DataType(DataType.EmailAddress)]
    [Display(Name = "E-Mail-Adresse")]
    public string Email { get; set; }

    [Required]
    [Display(Name = "Vorname")]
    public string FirstName { get; set; }

    [Required]
    [Display(Name = "Nachname")]
    public string LastName { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [MinLength(5)]
    [Display(Name = "Passwort")]
    public string Password { get; set; }

    ...
}

And the following view:

以及以下视图：

@using (Html.BeginForm("Register", "Useraccount", FormMethod.Post, new { id = "registerUseraccountForm", @class = "ym-form" }))
{
    @Html.ValidationSummary(true)        

    <div class="ym-grid">
        <div class="ym-g50 ym-gl">
            <div class="ym-fbox-text">
                @Html.LabelForRequired(model => model.RegisterUseraccount.FirstName, null)               
                @Html.EditorFor(model => model.RegisterUseraccount.FirstName, new { required = "required", name = "firstName" })
                @Html.ValidationMessageFor(model => model.RegisterUseraccount.FirstName)                  
            </div>
        </div>
    ...

and my JavaScript

和我的 JavaScript

function sendForm(target) {
    alert(data);
    $.ajax({
        url: target,
        type: "POST",
        contentType: 'application/json',
        data: $("#registerUseraccountForm").serialize(),
        success: ajaxOnSuccess,
        error: function (jqXHR, exception) {
            alert('Error message.');
        }
    });

This is the result of the serialization:

这是序列化的结果：

RegisterUseraccount.FirstName=Peter&RegisterUseraccount.LastName=Miller&RegisterUseraccount.Email=miller%40gmail.com&RegisterUseraccount.Password=admin

This is my controller method I'm trying to POST to:

这是我试图发布到的控制器方法：

[HttpPost]
public ActionResult Register(RegisterUseraccount registerUseraccount)
{
    ...
}

... but the data doesn't arrive at the method, I get an error 404. I think the modelbinder can't work.

...但数据没有到达方法，我收到错误 404。我认为模型绑定器无法工作。

What works is data which is sent with the name firstName=Peter, but what actually is sent is RegisterUseraccount.FirstName=Peter.

有效的是以名称 firstName=Peter 发送的数据，但实际发送的是 RegisterUseraccount.FirstName=Peter。

How can I handle this problem?

我该如何处理这个问题？

remove contentType: 'application/json',and modify it to better (from my perspective)

删除contentType: 'application/json',并修改它以更好（从我的角度来看）

$('#registerUseraccountForm').submit(function () {
    if ($(this).valid()) {
        $.ajax({
            url: this.action,
            type: this.method,
            data: $(this).serialize(),
            beforeSend: function () {

            },
            complete: function () {

            },
            ...

Maybe you have this model

也许你有这个模型

public class YourModel
{
    public RegisterUseraccount RegisterUseraccount { get; set; }
}

In this case you have to put the model that corresponds to your action:

在这种情况下，您必须放置与您的操作相对应的模型：

[HttpPost]
public ActionResult Register(YourModel model)
{
    var registerUseraccount = model.RegisterUseraccount;
    ...
}

Or:

或者：

@using (Html.BeginForm("Register", "Useraccount", FormMethod.Post, new { id = "registerUseraccountForm", @class = "ym-form" }))
{
   @{ Html.RenderPartial("RegisterUseraccount"); }
}

RegisterUseraccount.cshtml

注册用户账号.cshtml

@model YourNamespace.RegisterUseraccount

@Html.ValidationSummary(true)        

<div class="ym-grid">
    <div class="ym-g50 ym-gl">
        <div class="ym-fbox-text">
            @Html.LabelForRequired(model => model.FirstName, null)               
            @Html.EditorFor(model => model.FirstName, new { required = "required", name = "firstName" })
            @Html.ValidationMessageFor(model => model.FirstName)                  
        </div>
    </div>

but you'll have to change some things like @Html.ValidationSummary (true).

但你必须改变一些东西，比如@Html.ValidationSummary (true).
