iOS shim for HTML 5 drag'n'drop

The HTML 5 drag'n'drop API allows you to implement drag'n'drop with the same code on most desktop browsers. Unfortunately, you'll notice iOS doesn't support it, so no iPad (or Android) action for you!

Luckily, WebKit gives us enough tools to shim seamlessly. If you drop this script in your page your existing HTML 5 drag'n'drop code should just work.

Demos

Check out the demo to see it in action. It should work on Android, but I don't have an Android phone to test. Let me know @timruffles.

Install/config

If you want enter/over/leave events, add a config object to the page before you include the shim.

<script>
var iosDragDropShim = { enableEnterLeave: true }
</script>
<script src="vendor/ios-drag-drop.js"></script>

Shim behaviour

all drag events, with dragenter, dragover and dragleave enabled via config flag
creates a partially transparent drag image based on the dragged element

Thanks

To the amazing contributors who've provided massive extensions and fixes to the original.
