从文件上传到dropzone

标签: javascript jquery html html5 dropzone.js

我在我的项目中使用多文件上传和其他字段,我想通过dropzone隐藏基本的html文件上传,所以我不想通过ajax发送文件,我只是想放弃文件,然后填写表格并在文件的同时将文件发送到服务器(当用户按下"发送")。

这是没有dropzone的工作电流形式,完美运行:

<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,但看起来它不起作用(没有可放置区域,上传按钮仍然存在)

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(); }
    }
};

感谢melc,它看起来很棒,但没有&#34;文件&#34;发布。这是帖子内容。在示例中有更多字段,因为我给出的示例更简单

使用js

// DropZone
Dropzone.options.dropzone = {
    paramName: "files", // The name that will be used to transfer the file
    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
});

使用dropzone时,可以根据以下三种方法发送其他数据。

  1. 将dropzone应用于包含输入字段的表单。
  2. 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
  3. 使用params属性。 (http://www.dropzonejs.com/#tips
  4. 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
  5. 第一种方法似乎符合运营的需要。可在此处找到此解决方案的指南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已发送的数据),

    示例中的post请求有效负载具有以下形式,

    Content-Type: text/plain
