Rather than each element which supports dimension attributes needing to
implement parsing the attributes and setting the appropriate style, we
can generalize this functionality. This will also make each element more
closely resemble the spec text, as we will be effectively declaring, for
example, "The img element supports dimension attributes" in code.
This is often used on login forms, for example, to toggle the visibility
of a password. The site will change the <input> element's type to "text"
to allow the password to show.
We had previous implemented some plumbing for file input elements in
commit 636602a54e.
This implements the return path for chromes to inform WebContent of the
file(s) the user selected. This patch includes a dummy implementation
for headless-browser to enable testing.
This creates a button to prompt users to select a file, and a label to
show information about the selected file(s). Clicking either shadow
element will activate the input element.
We currently copy-paste a series of if statements to selectively update
the shadow tree elements for some <input> types. This will soon become
longer as more shadow trees are implemented for other types.
This patch just moves those checks to a single location to make adding
more shadow trees easier.
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.
