Timothy Flynn	017ae80668	LibWeb: Validate form submissions whose submitter is not form-associated ... The spec for checking the no-validate state ends with a default return value of "false". However, we were only hitting this case for form- associated elements. If the submitter is the form itself, we want to enter the form validation steps.	2025-08-15 15:28:37 +02:00
mikiubo	23aadc02ca	LibWeb: Implement up/down arrow navigation in textarea	2025-08-15 06:32:11 -04:00
Timothy Flynn	c369f68eff	LibWeb: Delete entire graphemes when the delete/backspace key is pressed ... We currently delete a single code unit. If the user presses backspace on a multi code point emoji, they are going to expect the entire emoji to be removed. This now matches the behavior of Chrome and Firefox.	2025-08-14 22:21:51 +02:00
Glenn Skrzypczak	d25d62e74c	AK/Time+LibWeb/HTML: Fix ISO8601 week conversions ... This reimplements conversions between unix date times and ISO8601 weeks. The new algorithms also do not use loops, so they should be faster.	2025-08-14 11:05:28 -04:00
Glenn Skrzypczak	ec807d40dd	LibWeb/HTML: Correctly convert number to time/local datetime string ... This fixes a bug where non-zero milliseconds were previously not included if the second component was zero.	2025-08-14 11:05:28 -04:00
Glenn Skrzypczak	354fd56046	LibWeb/HTML: Step to next value without step mismatch ... Inputs now correctly step to the next valid value if they suffer a step mismatch.	2025-08-14 11:05:28 -04:00
Glenn Skrzypczak	a127f77602	LibWeb/HTML: Implement default value of range inputs ... Range inputs now always uses the default value if the value attribute is not set and the input is not dirty.	2025-08-14 11:05:28 -04:00
Glenn Skrzypczak	aea8650d8b	LibWeb/HTML: Enforce constraints on range inputs ... This extends the sanitization algorithm for range inputs in order to prevent overflow, underflow and step mismatch.	2025-08-14 11:05:28 -04:00
Glenn Skrzypczak	57376f8701	LibWeb/HTML: Ensure the year of month and week values is greater than 0 ... The validation algorithm for month and week inputs now also checks if the year is greater than zero.	2025-08-14 11:05:28 -04:00
Glenn Skrzypczak	544a6b21fc	LibWeb/HTML: Correctly normalize local datetime values ... Now trailing zeros in the second and millisecond part of local datetime values are removed during normalization.	2025-08-14 11:05:28 -04:00
Glenn Skrzypczak	cac2ee41b9	LibWeb/HTML: Correctly compute whether element is mutable ... This adapts the implementation of `is_mutable` to align more closely with the spec. Specifically, it is now also taken into account whether the element is enabled.	2025-08-14 11:05:28 -04:00
Kenneth Myhra	1228063a85	LibWeb: Enforce Integrity Policy on Fetch requests	2025-08-14 13:37:38 +01:00
CountBleck	d49fb169bc	LibWeb: Correct typos for user validity of form elements on submission ... The spec and comments say "set field's user validity to true", but we now actually set it to true and not false. This passes one subtest in WPT's css/selectors/user-valid.html.	2025-08-14 11:55:02 +02:00
Timothy Flynn	70db474cf0	LibJS+LibWeb: Port interned bytecode strings to UTF-16 ... This was almost a no-op, except we intern JS exception messages. So the bulk of this patch is porting exception messages to UTF-16.	2025-08-14 10:27:08 +02:00
Timothy Flynn	62d85dd90a	LibJS: Port RegExp flags and patterns to UTF-16	2025-08-13 09:56:13 -04:00
Timothy Flynn	b955c9b2a9	LibJS: Port the Identifier AST (and related) nodes to UTF-16 ... This eliminates quite a lot of UTF-8 / UTF-16 churn.	2025-08-13 09:56:13 -04:00
Timothy Flynn	8472e469f4	AK+LibJS+LibWeb: Recognize that our UTF-16 string is actually WTF-16 ... For the web, we allow a wobbly UTF-16 encoding (i.e. lonely surrogates are permitted). Only in a few exceptional cases do we strictly require valid UTF-16. As such, our `validate(AllowLonelySurrogates::Yes)` calls will always succeed. It's a wasted effort to ever make such a check. This patch eliminates such invocations. The validation methods will now only check for strict UTF-16, and are only invoked when needed.	2025-08-13 09:56:13 -04:00
Timothy Flynn	28d9d3a2c7	AK+Libraries: Reduce API surface of GenericLexer a bit ... * Remove completely unused methods. * Deduplicate methods that were overloaded with both StringView and char const* parameters. A future commit will templatize GenericLexer by char type. This patch serves to make that a tiny bit easier.	2025-08-13 09:56:13 -04:00
Lukas Schmidt	c2fc4b25cd	LibWeb: Implement HTMLElement.draggable()	2025-08-12 17:15:06 +01:00

Kenneth Myhra	e9246c15d9	LibWeb: Pass top-level navigation initiator origin to Fetch's Request	2025-08-12 07:08:33 -04:00
Andreas Kling	bd7599ccfc	LibCore: Remove macro-generated EventReceiver::try_create(...) factories ... We can just use the infallible factory everywhere instead.	2025-08-11 16:55:25 +02:00
Sam Atkins	4bcfc4bacc	LibWeb/HTML: Add cross-site ancestor flag to environment ... Corresponds to baec061a70	2025-08-11 11:08:04 +01:00
Sam Atkins	cfdc4bad7c	LibWeb: Update more navigation code to spec ... Partly corresponds to 80ebad5fbf This is mostly to handle null source_documents, which is something that needs more work elsewhere. The spec change above is about the deferred fetch quota.	2025-08-11 11:08:04 +01:00
Sam Atkins	0e5fd11bdc	LibWeb/HTML: Create navigation params for browser-UI navigations ... Step 4 corresponds to 3b6a99b1d9 The rest is from some earlier spec change.	2025-08-11 11:08:04 +01:00
Sam Atkins	cf969abba7	LibWeb/HTML: Add missing "else" to create_navigation_params_by_fetching	2025-08-11 11:08:04 +01:00
Sam Atkins	0b998b8379	LibWeb: Update base URL change processing ... Corresponds to 49f5cd381e	2025-08-11 11:08:04 +01:00
Idan Horowitz	5545d38d7a	LibWeb: Implement CookieStore::get(name)	2025-08-08 13:09:58 -04:00
Idan Horowitz	d6c2893663	LibWeb: Add initial CookieStore support	2025-08-08 13:09:58 -04:00
Timothy Flynn	4a8c70b3a5	LibWeb: Parse CSS/image URLs using DOMURL::parse ... DOMURL::parse handles blob URLs.	2025-08-08 17:47:51 +01:00
Timothy Flynn	9e474a4eb0	LibWeb: Add missing includes to SharedResourceRequest ... Missing Cell.h and Ptr.h were causing a bunch of clangd errors. Also remove unused includes while we're here.	2025-08-08 17:47:51 +01:00
Sam Atkins	6cad3f1921	LibWeb/CSS: Rename CSSColorValue -> ColorStyleValue ... The typed-om class will be a separate thing.	2025-08-08 15:19:03 +01:00
Sam Atkins	99bce9a94d	LibWeb/CSS: Replace CSSUnitValue with DimensionStyleValue ... CSSUnitValue is a typed-om type which we will implement separately in the future. However, it still seems useful to give our dimension values a base class. (Maybe they could be templated in the future?) So instead of deleting it entirely, rename it to DimensionStyleValue and make its API match our style better.	2025-08-08 15:19:03 +01:00
Sam Atkins	4e92ab52e3	LibWeb/CSS: Rename CSSKeywordValue -> KeywordStyleValue ... The typed-om CSSKeywordValue will need to be a separate class.	2025-08-08 15:19:03 +01:00
Sam Atkins	c57975c9fd	LibWeb: Move and rename CSSStyleValue to StyleValues/StyleValue.{h,cpp} ... This reverts 0e3487b9ab. Back when I made that change, I thought we could make our StyleValue classes match the typed-om definitions directly. However, they have different requirements. Typed-om types need to be mutable and GCed, whereas StyleValues are immutable and ideally wouldn't require a JS VM. While I was already making such a cataclysmic change, I've moved it into the StyleValues directory, because it *not* being there has bothered me for a long time. 😅	2025-08-08 15:19:03 +01:00
Edwin Hoksberg	1be31c103f	LibWeb: Stub WebSerial API	2025-08-08 10:23:17 +02:00
Luke Wilde	59162342e6	LibWeb: Set LinkProcessingOptions' cryptographic_nonce_metadata ... Fixes external CSS being blocked on https://beatsaver.com/, where they have a `style-src` directive set to `'self' 'nonce-[value]'` Relates to #5643, but does not make the website load.	2025-08-07 19:26:57 +02:00
Luke Wilde	1d57df6e26	LibWeb/CSP: Implement the sandbox directive	2025-08-07 19:24:39 +02:00
Luke Wilde	40bb50ac60	LibWeb: Parse and propagate the iframe sandbox attribute	2025-08-07 19:24:39 +02:00
Timothy Flynn	1bc80848fb	AK+LibWeb: Add a UTF-16 starts/ends with wrapper for a single code unit	2025-08-07 02:05:50 +02:00
Luke Wilde	4aa355658f	LibWeb/CSP: Implement the base-uri directive	2025-08-07 00:45:31 +02:00
Aliaksandr Kalenik	7a34bc2700	LibWeb: Re-evaluate media queries only when things they depend on change ... Before this change we were re-evaluating media queries on every frame which adds up in 1-4% in profiles on Discord.	2025-08-05 17:24:34 +02:00
Timothy Flynn	2dc0a3b3ce	AK: Add trim methods to Utf16String that skip allocation when not needed ... If the string does not begin with any of the provided code units, we do not need to create a new string.	2025-08-05 15:13:36 +02:00
Timothy Flynn	0efa98a57a	LibJS+LibWeb+WebContent: Port JS::PropertyKey to UTF-16 ... This has quite a lot of fall out. But the majority of it is just type or UDL substitution, where the changes just fall through to other function calls. By changing property key storage to UTF-16, the main affected areas are: * NativeFunction names must now be UTF-16 * Bytecode identifiers must now be UTF-16 * Module/binding names must now be UTF-16	2025-08-05 07:07:15 -04:00
Idan Horowitz	aeb7b442d3	LibWeb: Add initial support for bitmap cropping to createImageBitmap	2025-08-04 23:39:11 +02:00
Callum Law	e0e00220fe	LibWeb: Handle Auto resolution within Page::preferred_color_scheme ... Handling this here means we don't have to it within individual callers	2025-08-04 11:29:05 +01:00
Callum Law	46153910ec	LibWeb: Update to_color to take ColorResolutionContext ... Using a generic context argument will allow us to resolve colors in places where we have all the required information but not in the form of a layout node as was expected previously.	2025-08-04 11:29:05 +01:00
Idan Horowitz	ba6b82464c	LibWeb: Add initial support for SVGImageElement in createImageBitmap	2025-08-03 21:47:48 +02:00
Idan Horowitz	3b8ccf4d77	LibWeb: Add initial support for HTMLImageElement in createImageBitmap	2025-08-03 21:47:48 +02:00
Idan Horowitz	cc0496284b	LibWeb: Add a getter for the default image bitmap of HTMLImageElement ... The default image bitmap is the first frame for animated bitmaps, and the only frame for non-animated bitmaps.	2025-08-03 21:47:48 +02:00
