Also addresses issue #1439.
I don’t like the binding iframe.on('load') events in the onclick handler, but apparently Entwine doesn't support binding on iframes.
AssetAdmin and HtmlEditorField support added
The detection is triggered on first load, and in IE8 the
inserted value doesn't equal the value already in the textarea field.
That's possibly due to whitespace or encoding differences,
but they have the same character length.
Tried fixing this by whitespace removal, didn't work:
if((original || '').replace(/[\s\t\n\r]/g, '') != (value || '').replace(/[\s\t\n\r]/g, '')) {
In the end, we're already detecting changes through a 5s interval
triggering the save() method on the editor if the field is focused.
The impact of this removal is that after inserting an image,
it'll take a few seconds for the change detection to kick in
(and thus highlight the "save" button and ask for confirmation
when navigating away without saving).
See d12ae82f70 for context.
We werent calling tinyMCE.Editor.destroy, which is needed to
clean up event bindings. The advanced theme also wasnt cleaning
up after itself on destroy properly
It doesn't make sense to show it there, since the "delete"
action has no effect, the "edit" button only collapses (useless),
and the thumbnail duplicates.
Wasn't parsing data-editor attrs correctly.
Using proper instances of the underlying editor now,
instead of relying on "active editor" states which get
wonky once they lose focus (e.g. when opening a dialog).
Periodically check for inline changes when focused,
since TinyMCE's onChange only fires on certain actions
like inserting a new paragraph, as opposed to any user input.
This also works around an issue where the "save" button
wouldn't trigger if the click is the cause of a "blur" event
after an (undetected) inline change. This "blur" causes onChange
to trigger, which will change the button markup to show "alternative" styles,
effectively cancelling the original click event.
Inside mediaform updateFromEditor we called $(this).updateFromNode, but this wasnt
pointing to anything useful after a refactor, which resulted in the fields not
being filled in with current data when editing an already-inserted image
Otherwise some non-textual changes such as moving images and resizing
them could be missed when saving.
This is because TinyMCE does not treat the image move/resize as an
undolevel and does not register this via regular "onChange" event.
