从文件上传到dropzone

Question

我在项目中的其他字段上使用了多文件上传，并且我想按dropzone覆盖基本的html文件上传，所以我不想通过ajax发送文件，我只想删除文件，然后填写表格并在字段同时发送文件到服务器（当用户按下“发送”时）。

这是不带dropzone的当前工作形式，可以很好地工作：

<form action="/Document/Document/Create" enctype="multipart/form-data" method="post">
    <div class="form-horizontal">
        <hr>

        <div class="form-group">
            <div>
                <input name="files" type="file" id="files" multiple>
            </div>
        </div>

        <div class="form-group">
            <label class="control-label col-md-2" for="sourcePath">Source</label>
            <div class="col-md-10">
                <input class="form-control text-box single-line" data-val="true" data-val-required="Le champ Source est requis." id="sourcePath" name="sourcePath" type="text" value="">
                <span class="field-validation-valid text-danger" data-valmsg-for="sourcePath" data-valmsg-replace="true"></span>
            </div>
        </div>

        <div class="form-group">
            <label class="control-label col-md-2" for="name">Nom</label>
            <div class="col-md-10">
                <input class="form-control text-box single-line" data-val="true" data-val-required="Le champ Nom est requis." id="name" name="name" type="text" value="">
                <span class="field-validation-valid text-danger" data-valmsg-for="name" data-valmsg-replace="true"></span>
            </div>
        </div>

        <div class="form-group">
            <label class="control-label col-md-2" for="reference">Référence</label>
            <div class="col-md-10">
                <input class="form-control text-box single-line" data-val="true" data-val-required="Le champ Référence est requis." id="reference" name="reference" type="text" value="">
                <span class="field-validation-valid text-danger" data-valmsg-for="reference" data-valmsg-replace="true"></span>
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default">
            </div>
        </div>
    </div>
</form>

这是我尝试过的方法，但它似乎不起作用（没有可放置区域，仍存在上传按钮）

HTML

<div id="dropzone" class="dropzone">
    <div class="fallback">
        <input name="files" type="file" id="files" multiple />
    </div>
</div>

JS

// DropZone
Dropzone.options.dropzone = {
    paramName: "files", // The name that will be used to transfer the file
    maxFilesize: 10, // MB
    //uploadMultiple: true,
    autoProcessQueue: false,
    accept: function (file, done) {
        if (file.name == "justinbieber.jpg") {
            done("Naha, you don't.");
        }
        else { done(); }
    }
};

编辑：

多亏了melc，它看起来不错，但没有“文件”发布。 这是帖子内容。 该示例中还有更多字段，因为我给出的示例更简单

与js

Dropzone.options.dropzone = {

    maxFilesize: 10, // MB
    //uploadMultiple: true,
    autoProcessQueue: false,
    url: "/file/post",
    accept: function (file, done) {
        if (file.name == "justinbieber.jpg") {
            done("Naha, you don't.");
        }
        else { done(); }
    }
};

$(document).ready(function () {
    // stuff
});

Answer 1

使用dropzone时，可以根据以下三种方法发送其他数据。

将dropzone应用于具有输入字段的表单。
将dropzone应用于具有隐藏输入字段的表单。 字段的值可以用js填充。 （ http://www.dropzonejs.com/#tips ）
使用params属性。 （ http://www.dropzonejs.com/#tips ）
通过sending事件和formData参数将表单数据附加到每个文件。 （ http://www.dropzonejs.com/#tips ）

第一种方法似乎符合操作员的需求。 有关此解决方案的指南，请参见https://github.com/enyo/dropzone/wiki/Combine-normal-form-with-Dropzone 。

请根据您的示例找到此解决方案的粗略但成功的尝试（需要检查来自浏览器开发工具的网络调用以查看发送的数据），

该示例中的发布请求有效负载具有以下形式：

------WebKitFormBoundary0Mm4s3UDxfPPh1DR
Content-Disposition: form-data; name="sourcePath"

value of field1
------WebKitFormBoundary0Mm4s3UDxfPPh1DR
Content-Disposition: form-data; name="name"

value of field2
------WebKitFormBoundary0Mm4s3UDxfPPh1DR
Content-Disposition: form-data; name="reference"

value of field3
------WebKitFormBoundary0Mm4s3UDxfPPh1DR
Content-Disposition: form-data; name="null"

Create
------WebKitFormBoundary0Mm4s3UDxfPPh1DR
Content-Disposition: form-data; name="file[0]"; filename="test1.txt"
Content-Type: text/plain
