Now it seems that the accept function is called when a file is added but not when a file is removed from the dropzone. So is it possible to invoke the accept function programmtically? This is a less than optimal solution, but I've found that if you mimic the drop functionality with your existing files programmatically, you can achieve a similar result of 'reprocessing existing files'.

This involves storing the files to a variable, removing the files from the Dropzone object and adding the file s back in. From your javascript file do:. Learn more. Asked 6 years, 8 months ago. Active 3 years, 8 months ago.

But, when I test the same page in IE10 drag and drop does not work. The drop zone is clickable and I can upload the files to the server, thus the dropzone is initialized correctly. It is just the drag and drop feature that does not work. I have checked the IE internet options and everything is enabled and I also added the localhost to trusted sites. It turns out that drag and drop does not work when I access the page in debug mode from Visual Studio. If I access the page from a newly opened browser it works just fine.

In my case Visual Studio is running as Administrator. Since I do not need to debug the client scripts on this page I will just open the site in a fresh IE when I test the page.

Technical site integration observational experiment live on Stack Overflow.September 20, 11 min read Drag and drop UI has become an integral part of most modern applications. It provides richness in UI without comprising the UX. Today, we are going to see some of these use cases of drag and drop by building a simple project in React.

If you are curious about what the project looks like you can find it here. We are not going to reinvent the wheel by creating all the logic and components on our own. Instead, we will be using the most standard and famous libraries in our project. For drag and drop upload feature, we will use one of the most famous libraries in React called react-dropzone.

It has over 6k stars on Github and is up to date with React Hooks support. You can read the documentation here. It is a very powerful library and helps create custom components in React. For our project, we are mostly interested in three different properties:. In our example, we only used two props. The library supports a lot of props to customize the dropzone area based on your need. We used accept props to only allow image files.

Our App. We have added the dropzone component in the main page. Now, if you drop the files, it will console the dropped image files.

For that, we are going to create another component called ImageList. We have successfully completed half of our application. We will be able to upload files using drag and drop and also be able to see a preview of the images.

Next, we will allow reordering the previewed images using drag and drop functionality. Before doing that, we will see some of the different libraries used for such a solution and how to choose the one among them based on our application need. All are equally popular among React developers and also have active contributors but each library has pros and cons. For our use case, I pick react-dnd. I would pick react-beautiful-dnd if our layout just involves a list of items.

But in our example, we have an image grid. So the next easiest API for achieving drag and drop is react-dnd. Before we dive into the drag and drop code, we need to first understand how react-dnd works. React DND can make any element draggable and also make any element droppable. In order to achieve this, react dnd has a few assumptions:. It supports:.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

My goal with RDU was to build a lightweight, customizable dropzone and uploader with a minimal API, sensible defaults, and great support for TypeScript.

It tries to make the easy things effortless, and the hardest things possible. There's also the popular and solid react-dropzonebut this library only gives you a dropzone — it has no API for managing uploads.

File uploads with status, progress, cancellation and restart are hard to get right. And they're the most common use case for a dropzone, so I thought it would be nice to build a library that gives you a dropzone AND handles file uploads. I also wanted a friendlier rendering API and better rendering defaults.

Of course it lets you access them and take full control of rendering using the component injection API if you want to. Uploads files, and removes them if upload is successful. Doesn't handle upload failure. Previews have no upload progress.

No active state on drag over. No reject state if dragged files have incorrect file types. Behaves incorrectly if user drags a second group of files before first group has finished uploading bonus points if you can spot why this happens.

For example, I don't know much about writing tests for React components, and I know RDU would benefit from having them. I'd also like better support for older browsers. Examples Live Examples S3 Uploader. The others weren't really built for React. They're wrappers around fine-uploader and Dropzone. Both weigh many times more than RDU.

They're not maintained. The react-fine-uploader and fine-uploader repos were shut down in React-Dropzone-Component hasn't seen a commit to source code since ; pretty much ditto with Dropzone.

React Dropzone There's also the popular and solid react-dropzonebut this library only gives you a dropzone — it has no API for managing uploads.

You have to write them yourself, which means lots of boilerplate for even basic previews. It doesn't provide default styles. This makes no difference if you style everything yourself, but I wanted a component, like React Selectthat looks good and works well out of the box, and makes it trivial to override individual styles. It actually renders nothing by default.

To render anything you have to pass a render prop as a child of Dropzone. Contributing If you like RDU and want to make it better, read on!RDU is modular. In the Quick Start example, the only prop needed to perform uploads is getUploadParams. Want to disable the file input? Pass null for InputComponent. Don't want to show file previews?

Pass null for PreviewComponent. Don't need a submit button after files are uploaded? Pass null for SubmitButtonComponentor simply omit the onSubmit prop. Don't want to upload files? Omit getUploadParamsand you'll have a dropzone that calls onChangeStatus every time you add a file. This callback receives a fileWithMeta object and the file's status.

If status is 'done'the file has been prepared and validated.

react dropzone accept

Add it to an array of accepted files, or do whatever you want with it. It receives fileWithMeta, status, []fileWithMeta. The first argument is the fileWithMeta object whose status changed, while the third argument is the array of all fileWithMeta objects being tracked by the dropzone.

Returning a meta object from this callback lets you merge new values into the file's meta. If this prop isn't passed, RDU doesn't initiate and manage file uploads. The only required key is url. POST is the default method. If you pass your own request bodyRDU uploads it using xhr. If you don't, RDU creates the request body for you. It creates a FormData instance and appends the file to it using formData. It receives []fileWithMeta, []fileWithMeta.

The second argument is the array of all fileWithMeta objects being tracked by the dropzone. RDU maintains an array of files it's currently tracking and rendering. The elements of this array are fileWithMeta objects, which contain the following keys:. These objects give you all the metadata you need to create a customized, reactive file dropzone, file input, or file uploader.

Note that fileWithMeta objects are mutable. If you mutate them, RDU may behave unexpectedly, so don't do this!By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
