We now validate that the provided tag names are valid XML tag names,
and otherwise throw an "invalid character" DOM exception.
2% progression on ACID3. :^)
Note that we implement .elements as a HTMLCollection for now, instead of
the correct HTMLFormControlsCollection subclass. This covers most
use-cases already.
1% progression on ACID3. :^)
This API now follows the spec a bit more closely, with regards to the
event being dispatched. There are still FIXME's but this is already an
improvement.
2% progression on ACID3. :^)
This necessitated making HTMLParser ref-counted, and having it register
itself with Document when created. That makes it possible for scripts to
add new input at the current parser insertion point.
There is now a reference cycle between Document and HTMLParser. This
cycle is explicitly broken by calling Document::detach_parser() at the
end of HTMLParser::run().
This is a huge progression on ACID3, from 31% to 49%! :^)
This implements basic support for dynamic markup insertion, adding
* Document::open()
* Document::write(Vector<String> const&)
* Document::writeln(Vector<String> const&)
* Document::close()
The HTMLParser is modified to make it possible to create a
script-created parser which initially only contains a HTMLTokenizer
without any data. Aditionally the HTMLParser::run method gains an
overload which does not modify the Document and does not run
HTMLParser::the_end() so that we can reenter the parser at a later time.
Furthermore all FIXMEs that consern the insertion point are implemented
wich is defined in the HTMLTokenizer. Additionally the following
member-variables of the HTMLParser are now exposed by getter funcions:
* m_tokenizer
* m_aborted
* m_script_nesting_level
The HTMLTokenizer is modified so that it contains an insertion
point which keeps track of where the next input from the Document::write
functions will be inserted. The insertion point is implemented as the
charakter offset into m_decoded_input and a boolean describing if the
insertion point is defined. Functions to update, check and {re}store the
insertion point are also added.
The function HTMLTokenizer::insert_eof is added to tell a script-created
parser that document::close was called and HTMLParser::the_end() should
be called.
Lastly an explicit default constructor is added to HTMLTokenizer to
create a empty HTMLTokenizer into which data can be inserted.
Also, update the expected hash in the LibWeb TestHTMLTokenizer
regression test.
This is due to the "This comment has a few too many dashes." comment
token being updated.
Newline normalization will replace \r and \r\n with \n.
The spec specifically states
> Before the tokenization stage, the input stream must be preprocessed
> by normalizing newlines.
wheras this is implemented the processing during the tokenization
itself.
This should still exhibit the same behaviour, while keeping the
tokenization logic in the same place.
In 'NamedCharacterReference' we attempt to lookup the code point by a
identifier, eg apos; becomes '
This is done by passing the entire rest of the document to the
`HTML::code_points_from_entity` function.
However, before this change we didn't sent the final character which
meant if the document ended in a named character reference the lookup
would fail.
The entry we get from the active formatting elements list during the
Rewind step of "reconstruct the active formatting elements" can be a
marker. Previously we assumed it was not a marker, which can trigger
an assertion failure with certain malformed HTML.
If the entry in this step is a marker, the spec simply ignores it.
This is step 6 of the algorithm.
This also makes the index unsigned, as this algorithm is a no-op if
the list is empty.
Additionally, this also adds spec comments to this algorithm.
Fixes#12668.
This patch adds a default padding around the contents of text <input>
elements. It adds these defaults to the existing style attribute in
'HTMLInputElement::create_shadow_tree_if_needed()'.
Use a default padding for text <input> elements:
- padding-top and padding-bottom: 1px
- padding-left and padding-right: 2px
These values seems to align with what other browsers do.
Previously it would accept any DOMString, as we didn't support enums at
the time. Now it will only accept what's specified in the
DOMParserSupportedType enum.
This also adds spec comments to DOMParser::parse_from_string.
WebSockets got moved from the HTML standard to their own, the new
WebSockets Standard (https://websockets.spec.whatwg.org).
Move the IDL file and implementation into a new WebSockets directory and
C++ namespace accordingly.
This makes React react to checkboxes. Apparently they ignore the
"change" event in favor of "click" on checkboxes. This is a
compatibility hack for IE8.
Once we paint, it's way too late for this check to happen anyway.
Additionally, the spec's steps for retrieving the content document
assume that both the browsing context's active document and the
container's node document are non-null, which evidently isn't always the
case here, as seen by crashes on the SerenityOS 2nd and 3rd birthday
pages (I'm not sure about the details though).
Fixes#12565.
I can't imagine how this happened, but it seems we've managed to
conflate the "event listener" and "EventListener" concepts from the DOM
specification in some parts of the code.
We previously had two things:
- DOM::EventListener
- DOM::EventTarget::EventListenerRegistration
DOM::EventListener was roughly the "EventListener" IDL type,
and DOM::EventTarget::EventListenerRegistration was roughly the "event
listener" concept. However, they were used interchangeably (and
incorrectly!) in many places.
After this patch, we now have:
- DOM::IDLEventListener
- DOM::DOMEventListener
DOM::IDLEventListener is the "EventListener" IDL type,
and DOM::DOMEventListener is the "event listener" concept.
This patch also updates the addEventListener() and removeEventListener()
functions to follow the spec more closely, along with the "inner invoke"
function in our EventDispatcher.
Pages such as https://html5test.com are testing all sorts of weird,
incomplete, and wrong HTML but can be useful or at least interesting for
development - let's try to avoid crashing the process.
This is needed to access the 'adjusted current node' in the 'Markup
declaration open state'. We don't want to create a full parser for
something like syntax highlighting, so it's optional (null) by default.
If we try to <link> a stylesheet that was already cached, we'll get a
synchronous resource_did_load() callback. Because of this, it's
necessary to set up the document load event delayer *before* calling
set_resource(), as otherwise we'd be stuck without a load event forever.
This ensures that the layout information is current, even when the
scroll request happens immediately upon page load.
This fixes an issue where reloading ACID2 wouldn't scroll down to the
"#top" anchor point.
This is no longer needed as BrowsingContextContainer::content_document()
now does the right thing, and HTMLIFrameElement.contentDocument is the
only user of this attribute. Let's not invent our own mechanisms for
things that are important to get right, like same origin comparisons.
The HTML Origin spec has two similar but slightly different concepts of
origin equality: "same origin" and "same origin-domain". Let's be
explicit with the naming here :^)
Also add spec comments.
Emitting tokens on EOF caused an infinite loop, freezing the app, which
could be a bit annoying when writing an HTML comment at the end of
the file in Text Editor. :^)
Commit b193351a99 caused the HTML comments to flash when changing
the text cursor. Also, when double-clicking on a comment, the selection
started from the beginning of the file instead.
The following message was displaying when `TOKENIZER_TRACE_DEBUG`
was enabled:
(Tokenizer::nth_last_position) Invalid position requested: 4th-last
of 4. Returning (0-0).
Changing the `nth_last_position` to 3 fixes this. I'm guessing that's
because the parser is at that moment on the second hyphen of the `<!--`
string, so it has to go back only by three characters.
The difference should be between m_utf8_iterator and the
the new position, if m_prev_utf8_iterator is used one fewer
source position is popped than required.
This issue was not apparent on most pages since restore_to
used for tokens such <!doctype> that are normally
followed by a newline that resets the column to zero,
but it can be seen on pages with minified HTML.
