Issue with --data-ajax--url and jquery 1.11.2

[loic]

--data-ajax--url is ignored while the deprecated --data-ajax-url work.

http://jsbin.com/wotamodeco/1 demonstrates the issue.

Just following up on this some more based on conversations on IRC.

This appears to be a difference in how jQuery 1.x and 2.x parse the data attributes. I've created two jsbins that clearly reproduce the differences.

1.x: http://jsbin.com/zudohezome/1/edit?html,js,output
2.x: http://jsbin.com/zudohezome/2/edit?html,js,output

This is definitely a jQuery bug, as the HTML5 dataset attribute requires that the second dash is left. Here is a jsbin that confirms it: http://jsbin.com/ruratofulu/1/edit?html,js,output

I added a note to the documentation about this in caeb0ec, but unfortunately it does not look like the fix will be released for jQuery any time soon. As there is not much that we can do, aside from preferring dataset when possible, I'm going to close this off once I implement the dataset check.

That will still mean that it still won't work in older browsers (IE 10 and below), but there isn't much that we can do about it.

I think there should be a workaround for this (with attributes). Or is it there already?

The documentation still says that this is not supported with jQuery 1.x, or has this been resolved with the recent changes in jquery?

[kevin-brown]

This is still an issue with jQuery 1.x and was not fixed in the recent 1.11.3 release.

It is still fixed in the jQuery 2.x line and upcoming 3.x line.

Can't we have an alternative syntax to get it working with jquery 1.x?
