“dropzone.js”是最常用的上传图片的库。如果您想将“dropzone.js”作为表单的一部分,您应该执行以下步骤:
1)对于客户端:
HTML :
    <form action="/" enctype="multipart/form-data" method="POST">
        <input type="text" id ="Username" name ="Username" />
        <div class="dropzone" id="my-dropzone" name="mainFileUploader">
            <div class="fallback">
                <input name="file" type="file" multiple />
            </div>
        </div>
    </form>
    <div>
        <button type="submit" id="submit-all"> upload </button>
    </div>
查询:
    <script>
        Dropzone.options.myDropzone = {
            url: "/Account/Create",
            autoProcessQueue: false,
            uploadMultiple: true,
            parallelUploads: 100,
            maxFiles: 100,
            acceptedFiles: "image/*",
            init: function () {
                var submitButton = document.querySelector("#submit-all");
                var wrapperThis = this;
                submitButton.addEventListener("click", function () {
                    wrapperThis.processQueue();
                });
                this.on("addedfile", function (file) {
                    // Create the remove button
                    var removeButton = Dropzone.createElement("<button class='btn btn-lg dark'>Remove File</button>");
                    // Listen to the click event
                    removeButton.addEventListener("click", function (e) {
                        // Make sure the button click doesn't submit the form:
                        e.preventDefault();
                        e.stopPropagation();
                        // Remove the file preview.
                        wrapperThis.removeFile(file);
                        // If you want to the delete the file on the server as well,
                        // you can do the AJAX request here.
                    });
                    // Add the button to the file preview element.
                    file.previewElement.appendChild(removeButton);
                });
                this.on('sendingmultiple', function (data, xhr, formData) {
                    formData.append("Username", $("#Username").val());
                });
            }
        };
    </script>
2)对于服务器端:
ASP.NET MVC
    [HttpPost]
    public ActionResult Create()
    {
        var postedUsername = Request.Form["Username"].ToString();
        foreach (var imageFile in Request.Files)
        {
        }
        return Json(new { status = true, Message = "Account created." });
    }
