Question

我在本网页应用程序mvc 5中使用本教程创建了dropzone区域。

但是当我拖放我的图像时，dropzone布局并不起作用。下面是我的代码：

_layout

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>@ViewBag.Title - My ASP.NET Application</title>
    @Styles.Render("~/Content/css")
    @Styles.Render("~/Content/dropzonescss")
    @Scripts.Render("~/bundles/modernizr")
</head>
<body>
    <div class="navbar navbar-inverse navbar-fixed-top">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                @Html.ActionLink("Application name", "Index", "Home", null, new { @class = "navbar-brand" })
            </div>
            <div class="navbar-collapse collapse">
                <ul class="nav navbar-nav">
                    <li>@Html.ActionLink("Home", "Index", "Home")</li>
                    <li>@Html.ActionLink("About", "About", "Home")</li>
                    <li>@Html.ActionLink("Contact", "Contact", "Home")</li>
                </ul>
            </div>
        </div>
    </div>
    <div class="container body-content">
        @RenderBody()
        <hr />
        <footer>
            <p>&copy; @DateTime.Now.Year - My ASP.NET Application</p>
        </footer>
    </div>

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    @Scripts.Render("~/bundles/dropzonescripts")
    <script type="text/javascript">

        Dropzone.options.dropzoneJsForm = {

            //prevents Dropzone from uploading dropped files immediately
            autoProcessQueue: false,

            init: function () {
                var submitButton = document.querySelector("#submit-all");
                var myDropzone = this; //closure

                submitButton.addEventListener("click", function () {

                    //tell Dropzone to process all queued files
                    myDropzone.processQueue();
                });

            }
        };

    </script>

    @RenderSection("scripts", required: false)
</body>
</html>

索引

@{
    ViewBag.Title = "Home Page";
}


<form action="~/Home/SaveUploadedFile" method="post" class="dropzone" id="Dropzone.options.dropzoneJsForm" >
    <div class="fallback">
        <input name="file" type="file" multiple />
        <input type="submit" value="Upload" />
    </div>
</form>

的HomeController

public ActionResult SaveUploadedFile()
{
    bool isSavedSuccessfully = true;
    string fName = "";
    try
    {
        foreach (string fileName in Request.Files)
        {
            HttpPostedFileBase file = Request.Files[fileName];
            //Save file content goes here
            fName = file.FileName;
            if (file != null && file.ContentLength > 0)
            {

                var originalDirectory = new DirectoryInfo(string.Format("{0}Images\\WallImages", Server.MapPath(@"\")));

                string pathString = System.IO.Path.Combine(originalDirectory.ToString(), "imagepath");

                var fileName1 = Path.GetFileName(file.FileName);

                bool isExists = System.IO.Directory.Exists(pathString);

                if (!isExists)
                    System.IO.Directory.CreateDirectory(pathString);

                var path = string.Format("{0}\\{1}", pathString, file.FileName);
                file.SaveAs(path);

            }

        }

    }
    catch (Exception ex)
    {
        isSavedSuccessfully = false;
    }


    if (isSavedSuccessfully)
    {
        return Json(new { Message = fName });
    }
    else
    {
        return Json(new { Message = "Error in saving file" });
    }
}

BundleConfig add

bundles.Add(new StyleBundle("~/Content/dropzonescss").Include(
         "~/Scripts/dropzone/css/basic.css",
         "~/Scripts/dropzone/css/dropzone.css"));
bundles.Add(new ScriptBundle("~/bundles/dropzonescripts").Include(
         "~/Scripts/dropzone/dropzone.js"));

我不知道它为什么会这样。加载部分工作正常，但图形错误，看起来像：

看起来dropzone nuget包没有为dropzone css文件创建\ css子文件夹，因此bundle config不正确。（这是正确的，但文件夹不存在）。

创建文件夹scripts \ dropzone \ css（并将css文件从scripts \ dropzone文件夹移动到该新文件夹）

通过查看github上的解决方案，您可以看到dropzone文件夹的外观：
