If the selection starts and ends in the middle of blocks, we need to merge
these after extracting the range. But we need to be careful not to merge if
the selection ends at a block, as we end up merging into a block that wasn't
selected.
Explicit opt-in to autoinstantiation (included in the default document.html)
means Squire may be loaded in sites that themselves are loaded in iframes,
without unexpected consequences.
Resolves#104.
- Better checks to precisely trim white space only at beginning and end of block
- Don't keep the contents of <head> or <style> tags if inserted into body.
- Always keep styles to preserve fidelity on paste.
Fixes#95.
Safari very rarely has a text/html version (even if you copy from within
Safari!) so you end up always pasting plain text. Better to use the fallback
method to grab the data.
* Update the path after making the changes, so UI buttons can update correctly.
* Focus the editor on completion, to match the behaviour of other commands.
* Merge all the gathered text nodes if they're adjacent, so we have a normalised
result.
1. Keeps all leaf nodes not just text nodes, so images etc. are not removed.
2. If the selection is not within a single block, it is expanded to the edges
of the blocks rather than splitting the blocks; this is unlikely to have
been what the user wanted.
3. More efficient tree traversal and manipulation; no duplication of nodes.
4. Records undo state before performing the action.
Pasting is hard to get right in the general case, not least because the
browsers give so little control over the process, leaving you to resort to
crappy hacks. But we can special case the pasting to a blockquote case fairly
easily, and I can't see any particular regression it should cause.
Fixes#59.
Need to consider zero-width space equivalent to no content.
Also cleanup empty inline nodes in general when cleaning up zero-width spaces
inside them.
Fixes#58
We need to know when the document is modified in order to fire an "input" event
and set the undo/redo state correctly. Observing keyup is imprecise, as it's
hard to tell whether the key press actually modified anything. Newer browsers
support mutation observers, which tell you precisely when something has changed.
For IE9/10, Opera 12 and other older browsers, we fall back to observing keyup
again.
Fixes#26.
Never really want to let the browser delete a selection; it always makes a mess
of it. This now covers the case when an English letter key or number key is
pressed when a selection exists. Handling this completely (to include all keys
that produce a symbol) is tricky due to cross-browser key event compatibility
issues.
Before, hitting enter at the start of the link would result in the link text
being removed from an <a> on the new line, and an empty <a> tag on the previous
line. Now the link remains on the new line as expected, and no empty <a> tag is
produced.
in the preceding block.
Just return a boolean for the TreeWalker filter fn. This diverges from the spec,
but since the goal of this implementation is not to fully implement the spec
and we're never going to use a native implementation, this doesn't matter and
the code is easier to read when the function is just returning a boolean like
any normal filter function.
* Be more liberal in tld, as there are now a billion new ones, of every length.
* Fix bug where if the URL contains an @ it would add it as a mailto link
instead.
Set the defaultBlockProperties property on a squire instance to an object and
it will use these properties when it has to create a new default block element.
If a text node at the beinning of a block began with white-space, it would mean
some situations where we should be doing all the transformations for
enter/delete/backspace were being left to the browser.
* Hit tab to increase list depth, or call increaseListLevel method.
* Hit enter on a blank item to decrease list depth, or call decreaseListLevel method.
The clean functions used a `this` reference to call createElement, but are
called as functions not methods so `this` is undefined. Instead, we'll get the
ownerDocument off the nodes passed in, then call the createElement function
directly.
This is now an instance method, whereas before it was global. Annoyingly, we
need to access this from from within fixCursor which has no reference to the
RTE instance itself (and it would be a pain to pass one down). For now, just
referring to the global `editor` variable if it exists (i.e. if the script
loaded in an iframe). Need a better solution longer term though.
* If you load the squire.js script into a top-level page rather than an iframe,
it will add a Squire constructor to the global scope.
* The Squire constructor can be used to instantiate multiple instances on the
same page without having to load/parse/execute the full code every time.
* For each instance, create a new iframe, then call `new Squire( document )`,
with the document node for each iframe.
If you copy a portion of text from word, it includes an image version of the text as well as an HTML version. On paste, we now ignore the image
representation on the clipboard if an HTML representation is present, so that
the text pastes as expected, rather than as an image.
If you removed an event listener whilst it was being fired, this would alter the
list of handlers, which would cause the fireEvent function to read past the end
of the array (and to skip the next listener). Now, we clone the array of
listeners before firing, so adding/removing listeners has no effect on an
already firing event.
Firefox incorrectly goes back/forward in history instead of moving the cursor to
the beginning/end of the line when you press cmd-left/right on a mac. We now
override this to do the right thing.
When cleaning up pasted content, we remove any empty inline tags. However, we
should not be stripping <img> tags (which are of course both inline and empty).
Webkit needs a special placeholder text node as it can't focus empty text nodes.
This was being cleaned up too early, before the user had a chance to enter any
text.
The previous test was incorrect. A <br> actually introduces a line break if
there is any non-whitespace after it in the block or if there is another <br>
after it in the block. It is irrelevant what comes before it in the block.
IE and Safari 5 loses the selection during the bookmarking process, so we must
always explicitly reset the selection after recording an undo state (which adds
a bookmark).
