我目前有一个HTML表单，用户填写他们希望张贴的广告的细节。我现在想能够添加一个dropzone上传出售的项目的图像。
我发现Dropzone.js似乎做了我需要的大部分。但是，在查看文档时，似乎需要将整个表单的类指定为dropzone(而不仅仅是input元素)。这意味着我的整个表单变成了dropzone。
是否有可能使用dropzone只是我的形式的一部分，即只指定元素作为类“dropzone”，而不是整个形式?
我可以使用单独的表单，但我希望用户能够通过一个按钮提交所有内容。
或者，是否有其他库可以做到这一点?
非常感谢

“dropzone.js”是最常用的上传图像的库。 如果你想让“dropzone.js”只是表单的一部分，你应该执行以下步骤:
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>
JQuery:
<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)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." });
}

试试这个
<div class="dropzone dz-clickable" id="myDrop">
<div class="dz-default dz-message" data-dz-message="">
<span>Drop files here to upload</span>
</div>
</div>
JS
<script>
Dropzone.autoDiscover = false;
Dropzone.default.autoDiscover=false;
$("div#myDrop").dropzone({
url: "/file/post",
});
</script>
5.7.0版本的工作解决方案
<form id="upload" enctype="multipart/form-data">
<input type="text" name="name" value="somename">
<input type="checkbox" name="terms_agreed">
<div id="previewsContainer" class="dropzone">
<div class="dz-default dz-message">
<button class="dz-button" type="button">
Drop files here to upload
</button>
</div>
</div>
<input id="dz-submit" type="submit" value="submit">
</form>
Dropzone.autoDiscover = false;
new Dropzone("#upload",{
clickable: ".dropzone",
url: "upload.php",
previewsContainer: "#previewsContainer",
uploadMultiple: true,
autoProcessQueue: false,
init() {
var myDropzone = this;
this.element.querySelector("[type=submit]").addEventListener("click", function(e){
e.preventDefault();
e.stopPropagation();
myDropzone.processQueue();
});
}
});
更进一步，sqram说，Dropzone有一个额外的未记录的选项，“hiddenInputContainer”。您所要做的就是将此选项设置为您希望将隐藏文件字段附加到的表单的选择器。瞧!”。dz- hide -input”文件字段，Dropzone通常添加到主体神奇地移动到你的形式。没有改变Dropzone源代码。
现在，虽然这可以将Dropzone文件字段移动到表单中，但该字段没有名称。所以你需要添加:
_this.hiddenFileInput.setAttribute("name", "field_name[]");
在这行之后删除zone.js:
_this.hiddenFileInput = document.createElement("input");
大约在547行。

}
你可以通过捕捉dropzone中的'sending'事件来修改formData。
dropZone.on('sending', function(data, xhr, formData){
formData.append('fieldname', 'value');
});
