When an <input type=image> button is clicked, we now send the (x,y)
coordinates of the click event (relative to the image) along with the
form submission data.
Regarding the text test, we can currently only test this feature with
dialogs. The headless-browser test infrastructure cannot yet handle the
resulting navigation that would occur if we were to test with normal
form submission.
This implements enough to represent <input type=image> with its loaded
source image (or fallback to its alt text, if applicable). This does not
implement acquring coordinates from user-activated click events on the
image.
The setter was missing an implementation for the default and default/on
value attribute modes. This patch adds a method to get the current value
attribute mode, and implements the value setter and getter based on that
mode according to the spec.
This involves passing the UserNavigationInvolvement from each form
associated element that triggers a submit through to the methods that
perform the actual navigation. While here, refactor HTMLFormElement to
use the new Bindings::NavigationHistoryBehavior enum.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

We currently fire the change event on <input> elements when they lose
focus. The spec allows for us to also fire the event when changes are
"committed", so long as such an action makes sense for the input type.
This patch detects when the return key is entered in an <input> element
and uses that as the commit action for text-related types. If no change
has occurred since the last commit, no change event is fired.
We currently create a shadow tree once for each DOM element that renders
with a shadow tree (e.g. <input>, <details>). If such an element is
removed from the DOM, we must remove its shadow tree. Otherwise, the
shadow tree will refer to the old document in perpetuity.
If the node is added back to a DOM, then recreate the shadow tree.
And dealing with the fallout of doing so. I am not 100% sure that it is
safe for us to be treating Strings in the value sanitization algorithm
in all cases as if they are ASCII, but this commit does not change any
existing behaviour there.
With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.
This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.
I left a few types unconverted to this mechanism because I got tired of
doing this. :^)
It's a little awkward that one caller of this is passing through an
Optional<String> and another an Optional<DeprecatedString>, but that
should be fixed some point in the future with further DeprecatedString
porting.
This commit removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>
Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.
This commit introduces 3 things:
- Support for the color type in HTMLInputElement itself
- A mechanism for handling non event loop blocking dialogs in Page
- The associated plumbing up to ViewImplementation
Frontends may add support for the color picker with the
ViewImplementation.on_request_color_picker function
HTMLTextAreaElement also needs to be told when its contained text node
has been edited, so let's make this functionality work for anyone who
extends the new EditableTextNodeOwner interface class.
This should allow us to add a Element::attribute which returns an
Optional<String>. Eventually all callers should be ported to switch from
the DeprecatedString version, but in the meantime, this should allow us
to port some more IDL interfaces away from DeprecatedString.
In particular:
- Don't include none submitter buttons.
- Use type_state() instead type() to avoid direct string comparisons
- Support the hidden _charset_ input
- Get form associated element's value directly instead of via the value
attribute
- Split line break normalization into a separate function so that it
can also be used by form submission.
We now create a flex container inside the input element's UA shadow tree
and add the placeholder and non-placeholder text as flex items (wrapped
in elements whose style we can manipulate).
This fixes the visual glitch where the placeholder would appear below
the bounding box of the input element. It also allows us to align the
text vertically inside the input element (like we're supposed to).
In order to achieve this, I had to make two small architectural changes
to layout tree building:
- Elements can now report that they represent a given pseudo element.
This allows us to instantiate the ::placeholder pseudo element as an
actual DOM element inside the input element's UA shadow tree.
- We no longer create a separate layout node for the shadow root itself.
Instead, children of the shadow root are treated as if they were
children of the DOM element itself for the purpose of layout tree
building.
ARIA has its own spec and is not part of the DOM spec, which is what the
Web::DOM namespace is for (https://www.w3.org/TR/wai-aria-1.2/).
This allows us to stay closer to the spec with function names and don't
have to add the word "ARIA" to identifiers constantly - the namespace
now provides that clarity.
Note that as of this commit, there aren't any such throwers, and the
call site in Heap::allocate will drop exceptions on the floor. This
commit only serves to change the declaration of the overrides, make sure
they return an empty value, and to propagate OOM errors frm their base
initialize invocations.
