How to Use HTML5 File Drag and Drop. Few people have experienced file drag and drop in a web. (no drag & drop support). You can also download the files to.

Dragging and dropping files from your desktop to a browser is one of the ultimate goals for web application integration. This is the first in a four-part series of posts which describes how to: • enable file dragging and dropping onto a web page element • analyze dropped files in JavaScript • load and parse files on the client • asynchronously upload files to the server using XMLHttpRequest2 • show a graphical progress bar while the upload occurs • use progressive enhancement to ensure your file upload form works in any browser (good news for all you IE6 fans!) • code it in plain ol’ JavaScript without a library. Big, Bad Browser Support Before we begin, this tutorial refers to several cutting-edge HTML5 techniques so expect support to be patchy. The code works today, but it’s possible the APIs will change and browsers will evolve. • Recent versions of Firefox and Chrome support all features and work perfectly.

• Opera can parse files in JavaScript, but file dropping and XMLHttpRequest2 uploading is not implemented. • IE and the desktop editions of Safari do not support any of the APIs. • Apple has disabled HTML file upload forms on the iPhone and iPad editions of Safari.

Updates: • May 10, 2013: This article has been translated into language by Anja Skrba from. • Feb 3, 2009: A seems to be the culprit in the permissions form example below not working correctly in Safari 4.

The code has been updated to work around this bug and the article below has been updated. Thanks to russbuelt for pointing this out. • Feb 3, 2009: Apparently, an example made by Apple which I reported not working in Safari does work in Safari 4.0.4 for Mac OS X. Thanks for Scott Straker for this information. Image Credit: Flickr user svartling has been talked about a lot lately, but it’s hard to find really useful information about implementing it across multiple browsers., and all have pages describing how to use it, but their examples seem to work only in their particular browser ( doesn’t even work in their own!

Updated, Jan. 11, 2009: Although I have not been able to get this example working on Safari 2.0.4 and 3.1.2 for OS X and 4.0.4 for Windows, I have received word that it works on Safari 4.0.4 on OS X). Remy Sharp’s great article was a good place for me to start — however, the examples didn’t work in Internet Explorer. I also thoroughly enjoyed JavaScript guru where he uses creative and colourful language to describe what he thought of the standard, the browser manufacturers, and the WHAT-WG. When normal people see the author of the respond negatively to a web technology, they would probably assume it would be a good sign to stay away from it. However, I am not normal. With a name like Zoltan, how could I possibly be normal?

So, I decided to find out for myself how bad HTML5 Drag and Drop really is. Almost immediately, I understood Koch’s reaction – the browser vendors have not implemented all the same features, and there are even a few quirks in how the features that are implemented work. However, after doing a lot of research, I found a common denominator that works well, with the help of a small bit of JavaScript that smooths out the edges. Despite the implementation flaws, Future-proof HTML5 Drag and Drop is not too hard for developers to use in their own applications. This article will explain how to do this step by step with many examples along the way. By the time you are done, you will be able to write useful drag and drop scripts of your own like in this example: Advantages Over Existing Drag and Drop Implementations Koch mentioned in his blog post that “Web developers MUST NOT (in the sense of RFC 2119) use HTML 5 drag and drop. They should use instead”.

I would argue that developers should use HTML5 drag and drop for the following reasons: • JavaScript Framework Independent: Most other (but not all) drag and drop implementations are tied into 3rd party frameworks like,. • Built-in Browser Support: HTML5 Drag and Drop is supported in Firefox 3.5+, Chrome 3.0+, Safari 3.0+ and Internet Explorer 5.0 ( Note: that is not a typo — HTML5 Drag and Drop is based on work done by Microsoft in 1999). Because it is part of HTML5, I assume Opera support should be inevitable. • Integration With Other Web Applications: the HTML5 specification will allow developers to produce drag and drop scripts that work across frames, and across browser windows. • Integration With Non-Web Applications: the HTML5 specification also allows users to drag and drop data to and from non-web applications The Basics of Drag and Drop, Step by Step In order to save other developers from the headaches I got deciphering cross browser drag and drop, I present the following guide that shows how to do in five easy steps.
