ASP.NET MVC的Ajax文件上传与jQuery插件的形式？

问题描述

我使用jQuery Ajax表格插件上传文件。 codeS：

I use Jquery Ajax Form Plugin to upload file. Codes:

AuthorViewModel

AuthorViewModel

public class AuthorViewModel
{
    public int Id { get; set; }

    [Required(ErrorMessage = "{0} alanı boş bırakılmamalıdır!")]
    [Display(Name = "Yazar Adı")]
    public string Name { get; set; }

    [Display(Name = "Kısa Özgeçmiş")]
    public string Description { get; set; }

    [Display(Name = "E-Posta")]
    public string Email { get; set; }

    public string OrginalImageUrl { get; set; }

    public string SmallImageUrl { get; set; }
}

表格

@using (Html.BeginForm("_AddAuthor", "Authors", FormMethod.Post, new { id = "form_author", enctype = "multipart/form-data" }))
{
    <div class="editor-label">
        <input type="file" name="file" id="file" />
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.ValidationMessageFor(model => model.Name)
    </div>

    ...

    <div class="submit-field">
        <input type="submit" value="Ekle" class="button_gray" />
    </div>
}

剧本

<script>
$(function () {
    $('#form_author').ajaxForm({
        beforeSubmit: ShowRequest,
        success: SubmitSuccesful,
        error: AjaxError
    });
});

function ShowRequest(formData, jqForm, options) {
    $(".loading_container img").show();
}

function AjaxError() {
    alert("An AJAX error occured.");
}

function SubmitSuccesful(result, statusText) {
    // Veritabanı işlemleri başarılı ise Index sayfasına
    // geri dön, değilse partial-view sayfasını yenile
    if (result.url) {
        window.location.href = result.url;
    } else {
        $(".authors_content_container").html(result);
    }
}
</script>

控制器

[HttpPost]
public ActionResult _AddAuthor(AuthorViewModel viewModel, HttpPostedFileBase file)
{
    ...
    viewModel.OrginalImageUrl = file.FileName;
    ...
}

以上codeS正常工作

Above codes work fine

问题

正如你看到的，我从后视图模型文件独立。有没有一种方法，以 HttpPostedFileBase文件属性添加到视图模型并将其绑定到视图模型考虑，并张贴在视图模型到控制器？

As you see, I post file seperate from ViewModel. Is there a way to add HttpPostedFileBase file property to ViewModel and bind it to viewModel in view, And post it to controller in ViewModel?

我希望，我可以解释。

编辑：

这codeS做工精细。我不想交，视图模型和HttpPostedFile分开。我想是这样的：（如果可能）。

This codes work fine. I dont want post , viewModel and HttpPostedFile seperately. I want something like this: (If it is possible.)

型号

public class AuthorViewModel
{
    public int Id { get; set; }

    [Required(ErrorMessage = "{0} alanı boş bırakılmamalıdır!")]
    [Display(Name = "Yazar Adı")]

    HttpPostedFileBase file{ get; set; }
    ...
}

控制器

[HttpPost]
public ActionResult _AddAuthor(AuthorViewModel viewModel)
{
    var file = viewModel.file;
    ...
}

感谢。

推荐答案

是的，你可以添加AliRızaAdıyahşi。

Yes you can add AliRıza Adıyahşi.

下面是属性做到这一点：

Here is the property to do it:

public HttpPostedFileBase File { get; set; }

现在在你建立你应该添加加密类型作为周小川马云说：

Now in you form you should add enctype as Xiaochuan Ma said:

@using (Html.BeginForm("_AddAuthor", "Authors", FormMethod.Post, new { id = "form_author", enctype="multipart/form-data" }))
{
    <div class="editor-label">
        <input type="file" name="file" id="file" />
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.ValidationMessageFor(model => model.Name)
    </div>

    ...

    <div class="submit-field">
        <input type="submit" value="Ekle" class="button_gray" />
    </div>
}

在你控制行动：

[HttpPost]
public ActionResult _AddAuthor(AuthorViewModel viewModel, HttpPostedFileBase file)
{
    if(file!=null)
    {
        viewModel.File=file; //Binding your file to viewModel property
    }
    //Now you can check for model state is valid or not.
    if(ModelState.IsValid)
    {
        //do something
    }
    else
    {
        return View(viewModel);
    }
}

希望它帮助。这是你所需要的？

Hope it helps. Is this what you need ?

修改

没有什么额外的事情。它会自动绑定到视图模型。

There is nothing additional to do. Its automatically binding to viewModel.

[HttpPost]
public ActionResult _AddAuthor(AuthorViewModel viewModel)
{
      var uploadedfile = viewModel.File;// Here you can get the uploaded file.
      //Now you can check for model state is valid or not.
    if(ModelState.IsValid)
    {
        //do something
    }
    else
    {
        return View(viewModel);
    }
}

这为我工作！
