Hi Hallvord,
This is wonderful news since getting the html from the clipboard right
now is a really ugly hack and very browser dependent.
Sure it is, we hope to fix that in a nice way :-)
Getting the clipboard data as both a string or a fragment would sure
make it easy for developers to handle clipboard contents.
I take that as support for my event.clipboardData.getDocumentFragment()
suggestion. I'll need to talk to Ian Hickson about it since the actual
DataTransfer definition is in HTML5, but I guess it might be interesting
also for DnD?
Regarding HTML sanitation:
The mozilla folks recently decided to clean up pasted HTML but it's a
bit too aggressive removing all non standard attributes. In order to for
example detect MS word HTML a lot of this odd content needs to be
retained to check for list like structures for example.
Yes, the getData() algorithm is not going to clean up non-standard
attributes/class names/elements.
I think the sanitation outlined in the document might also be a bit too
aggressive. Such as removing the HTML comments and data attributes. For
example both TinyMCE and CKEditor uses the data- attributes for internal
usage. So if a user is pasting from one editor to another cross domains
the attribute would be lost and therefor break that item.
I didn't know that you use data- attributes. This gets somewhat tricky -
data- is certainly a type of hidden data that should be removed under the
"to the greatest extent possible, a user should know what s/he is really
pasting" principle. I see your use case, but I also assume that many sites
would use data- attributes for information that the site doesn't expect
anybody but its own JS to get access to.
Also removing all style properties that is computed to 'none' would
remove browser specific CSS rules and mso- styles that we use to detect
word specific items.
What he algorithm actually intends is to remove all elements with
display:none (and visibility:hidden) - again based on the principle that
we should try to make sure the user knows what s/he is pasting.
I've reworked the stuff on pasting HTML (potentially with multiple parts)
today - please review this section at your leisure, particularly the
screenful known as sections 8.3 and 8.3.1:
