Can't upload the same file twice in a row about filedrop

[ProgerXP]

I know about this and tries this but not all browsers support setting file's input value even to empty value. Notably Opera won't allow it.

Does it fix IE at least?

The input.files property is read-only, but you can set the value for the input to be "".

I will change the code in my "fork", so you can see that I'm talking about.

The change for that is the following:

I don't know if that is the proper place to add this code, but this worked on Chrome and will probably work on IE.

Like I've said it (still) doesn't work on IE but at least it works on Chrome and Firefox (tested). Implemented in 528f2ca. Thanks for another correction.

You can make it work on IE too. But you need to remove the old input and add a new one in its place.
The following stackoverflow post explain how to do it using jQuery by cloning the old one, but you can do it on hand.

I'm not sure it's a good idea to swap the input every time - it will lose all event bindings which might have been added outside of FIleDrop as well.

I will think about this though.

[rafaelmaiolla]

I understand your concerns.

And I can implement the work-around for IE by myself...

If someone else need it, the code is the following (using jQuery - and of course this code is outside the library):

var $input = $(fileDrop.el).find(":file");
$input.replaceWith($input.clone());

fileDrop.opt.input = null;
fileDrop.hook(fileDrop.el);

I will actually implement this in the next update with an option to disable input recreation (will be enabled by default). So stay tuned.

[rafaelmaiolla]

Great!

[ProgerXP]

Implemented in 276e066. Turned out to be not so trivial (who would have guessed IE clones "by reference" and triggers submit once per every clone even after removing the old input?).

opt.recreateInput is true by default so your fix should be redundant now.

thanks for that, I will download the newer version.
