Question

HELP！

我正在构建网站的前端，我正在使用dropzone.js进行图片上传。现在我已经将dropzone.min.js和dropzone.css包含在头部中，并将dropzone类分配给我想要转换的标签。尽管如此，表单字段不会成为dropzone字段。在该字段上删除图像会导致浏览器只显示通常所做的图像。我使用了很多不同的jquery或javascript插件，所以可能会有一些导致冲突的东西？

Firebug控制台说：未捕获错误：未提供URL。

如果你们能帮我解决这个问题，那就太好了！提前致谢

Answer 1

即使我遇到同样的问题。经过几分钟的研究，我发现我们需要在不使用表单时为元素指定url。但在你的情况下，你已经使用form标签来实现dropzone，所以它需要一个像..

这样的动作

<form action="some_target_url" class="dropzone"></form>

这对我有用......就这样。

我在选项表中的dropzone.js网站（向下滚动）中找到了这个

Answer 2

HTML代码中的

<form class="dropzone" id="myDropzone" action="url.php">（甚至没有指定任何ID）都很好。那说：

可以在选项中的 javascript 中指定网址 - 方法：

1）如果自动发现被设为真（默认） Dropzone.options.myDropzone = { url : "url.php",...
对于JS，表单的id必须以表格形式声明：id="mydropzone"或＃my-dropzone
class="dropzone"是不够的。
注意：自动发现必须在dom准备好之后和之前声明。

2）如果Dropzone.autoDiscover = false：
var myDropzone = new Dropzone("#myDropzone", { url: "url.php",... // JS : Dropzone class
或
$("#myDropzone").dropzone({ url: "url.php",... // JS : jquery style
注意：你当然可以使用另一个id，代码将是Dropzone.options.myOtherId = ...，$（“＃myOtherId”）。dropzone ...等。

警告： jQuery文档就绪回调函数和 JQUERY 3 ：
"Uncaught Error: No URL provided."可能发生在一个条件下（这使我来到这里）：

情景1：
加载dropzone.js和jQuery 2 自动发现让真实然后，在jQuery文档准备就绪：Dropzone.options.myDropzone = {url：“url.php”，...
- ＆GT;一切都很好

情景2：
切换到jQuery 3而不做任何其他更改："Uncaught Error: No URL provided."
- ＆GT;没有工作

这似乎是因为jQuery处理doc的新方法准备好了： https://jquery.com/upgrade-guide/3.0/#breaking-change-document-ready-handlers-are-now-asynchronous

使用jQuery 3解决方案：
  1）让自动发现为真，并将所有代码OUTSIDE jQuery doc准备好   或
  2）在doc ready之前将autodiscover设置为false并通过Javascript IN doc ready声明选项（url等）

Answer 3

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

Answer 4

同样的问题 - 简单的解决方案 - ＆gt;我没有在他的配置中指定dropzone URL。

Module1.name

为什么我的dropzone javascript表单不起作用？
