Question

我真的没有一个很好的例子，主要是因为我只是扯着它，到目前为止，我的代码只是一个乱糟糟的混蛋 - dee哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇哇。我很茫然，需要一些帮助或建议。这就是我需要的：

我正在创建一个仅用于学习目的的模拟注册表单。我使用工作申请表作为我的例子。一页包含申请人的个人信息，如姓名，年龄，性别和教育程度。第二页允许他们选择他们希望申请的职位，并允许他们提供技能列表。我设置了一个model来将data和save设置为database。第一页将有一个ajax 下一个按钮，它将第一页表单替换为第二页表单。第二页有两个按钮，返回和提交（足够简单），也是ajax-y。我现在的问题是从两个表单中将data保存到entry中的单个model。有没有人有一个简单的例子或链接我可以考虑这种情况？或者甚至是另一种方式来解决这个问题？这将不胜感激！！：）

模型

public int Id { get; set; }

    [Required(ErrorMessage = "First name Req")]
    [Display(Name = "First name")]
    public string First { get; set; }

    [Required(ErrorMessage = "Last name Req")]
    [Display(Name = "Last name")]
    public string Last { get; set; }

    [Required(ErrorMessage = "Age Req")]
    [Range(18, 75, ErrorMessage = "Age Range of {1}-{2}")]
    public int Age { get; set; }

    [Required(ErrorMessage = "Please Select Gender")]
    public string Gender { get; set; }

    [Required(ErrorMessage = "Education Level Req")]
    public string Education { get; set; }

    public string Position { get; set; }

    public string Skills { get; set; }

好的，我会尝试让它尽可能短。因此，假设您已经知道如何在表单之间切换，我知道您根据您的问题进行切换，并且您有以下表单：

<form id="form1">
    @Html.EditorFor(model => model.First)
    // rest of the fields goes here
</form>
<form id="form2">
    @Html.EditorFor(model => model.Position)
    // rest of the fields goes here
    <button id="submitAll">Submit</button>
</form>

假设您有按钮来回切换视图。 submitAll按钮触发对控制器方法的回发操作，并传递如下值：

function submitAllFields() {
    var o = {
        // list properties here similar to your model property name
        // and assign values to them
        First: $("#First").val(),
        Position: $("#Position").val()
    };
    $.post('@Url.Action("apply2")', { app: o }, function(result) {
        // do something here
    });
}

然后，您需要一种方法来接受所有输入：

[HttpPost]
public PartialViewResult Apply2(Application app)
{
    if (ModelState.IsValid)
    {
        db.Entry(app).State = EntityState.Modified;
        db.SaveChanges();
        ModelState.Clear();
        return PartialView("_Success");
    }
    // do something here
}
