* Selector: Leverage the :scope pseudo-class where possibleMichał Gołębiowski-Owczarek2019-08-192-11/+35
| | | | | | | | | | | | | | | | | | | The `:scope` pseudo-class[1] has surprisingly good browser support: Chrome, Firefox & Safari have supported if for a long time; only IE & Edge lack support. This commit leverages this pseudo-class to get rid of the ID hack in most cases. Adding a temporary ID may cause layout thrashing which was reported a few times in [the past. We can't completely eliminate the ID hack in modern browses as sibling selectors require us to change context to the parent and then `:scope` stops applying to what we'd like. But it'd still improve performance in the vast majority of cases. [1] https://developer.mozilla.org/en-US/docs/Web/CSS/:scope Fixes gh-4453 Closes gh-4454 Ref gh-4332 Ref jquery/sizzle#405
* Selector: Bring back querySelectorAll shortcut usageMichał Gołębiowski-Owczarek2019-08-091-2/+1
| | | | | | | Due to a faulty IE 8 workaround removal, the fast path qSA mode was skipped when jQuery's find was called on an element node - i.e. in most cases. 😱 Ref gh-4395 Closes gh-4452
* Selector: Inline Sizzle into the selector moduleMichał Gołębiowski-Owczarek2019-07-2916-310/+1898
| | | | | | | | | | | | | | | | | | This commit removes Sizzle from jQuery, inlining its code & removing obsolete workarounds where applicable. The selector-native module has been removed. Further work on the selector module may decrease the size enough that it will no longer be necessary. If it turns out it's still useful, we'll reinstate it but the code will look different anyway as we'll want to share as much code as possible with the existing selector module. The Sizzle AUTHORS.txt file has been merged with the jQuery one - people are sorted by their first contributions to either of the two repositories. The commit reduces the gzipped jQuery size by 1460 bytes compared to master. Closes gh-4395
* Selector: Port Sizzle tests to jQueryMichał Gołębiowski-Owczarek2019-06-261-5/+9
| | | | | | | Apart from porting most Sizzle tests to jQuery (mostly to its selector module), this commit fixes selector-native so that a jQuery custom compilation that excludes Sizzle passes all tests as well. Closes gh-4406
* Build: ESLint: forbid unused function parametersMichał Gołębiowski-Owczarek2019-05-1316-34/+23
| | | | | | | | | | | | | This commit requires all function parameters to be used, not just the last one. In cases where that's not possible as we need to match an external API, there's an escape hatch of prefixing an unused argument with `_`. This change makes it easier to catch unused AMD dependencies and unused parameters in internal functions the API of which we may change at will, among other things. Unused AMD dependencies have been removed as part of this commit. Closes gh-4381
* Core: Remove IE-specific support tests, rely on document.documentModeMichał Gołębiowski-Owczarek2019-05-139-144/+41
| | | | | | | Also, update some tests to IE-sniff when deciding whether to skip a test. Fixes gh-4386 Closes gh-4387
* Traversing: Fix `contents()` on `<object>`s with children in IEMichał Gołębiowski-Owczarek2019-05-081-2/+9
| | | | | | | | | The original fix didn't account for the fact that in IE `<object>` elements with no `data` attribute have an object `contentDocument`. The fix leverages the fact that this special object has a null prototype. Closes gh-4390 Ref gh-4384 Ref gh-4385
* Traversing: Fix `contents()` on `<object>`s with childrenPat O'Callaghan2019-05-061-1/+1
| | | | Fixes gh-4384 Closes gh-4385
* Effect: Fix a unnecessary conditional statement in .stop()Wonseop Kim2019-05-011-1/+1
| | | | | | | | | Because of the above conditional, the 'type' variable has a value of type 'string' or undefined. Therefore, boolean comparisons for 'type' variable is always unnecessary because it return true. The patch removed the unnecessary conditional statement. Fixes gh-4374 Closes gh-4375
* Build: Fix AMD dependencies in curCSSMichał Gołębiowski-Owczarek2019-04-302-8/+1
| | | | | | | | | A leftover `rboxStyle` was left in the wrapper parameters but not in the dependency array, causing `getStyles` to be undefined in AMD mode. Since `rboxStyle` is no longer used, it's now removed. Ref gh-4347 Closes gh-4380
* Core: Drop support for IE <11, iOS <11, Firefox <65, Android Browser & PhantomJSMichał Gołębiowski-Owczarek2019-04-2951-657/+275
| | | | | | | | | | | Also, update support comments format to match format described in: https://github.com/jquery/contribute.jquery.org/issues/95#issuecomment-69379197 with the change from: https://github.com/jquery/contribute.jquery.org/issues/95#issuecomment-448998379 (open-ended ranges end with `+`). Fixes gh-3950 Fixes gh-4299 Closes gh-4347
* Core: Remove deprecated jQuery APIsMichał Gołębiowski-Owczarek2019-04-293-33/+4
| | | | Fixes gh-4056 Closes gh-4364
* Event: Stop shimming focusin & focusout eventsMichał Gołębiowski-Owczarek2019-04-293-67/+0
| | | | | | | | | | | Latest versions of all browsers now implement focusin & focusout natively and they all converged on a common event order so it doesn't make much sense for us to normalize it to a different order anymore. Note that it means we no longer guarantee that focusin fires before focus and focusout before blur. Fixes gh-4300 Closes gh-4362
* Data: Separate data & css/effects camelCase implementationsMichał Gołębiowski-Owczarek2019-04-295-17/+34
| | | | | | | | The camelCase implementation used by the data module no longer turns `-ms-foo` into `msFoo` but to `MsFoo` now. This is because `data` is supposed to be a generic utility not specifically bound to CSS use cases. Fixes gh-3355 Closes gh-4365
* Event: Prevent leverageNative from registering duplicate dummy handlersRichard Gibson2019-04-291-5/+5

* Build: Fix unresolved jQuery reference in finalPropNameMichał Gołębiowski-Owczarek2019-04-172-4/+12
| | | | | | | Also, prevent further similar breakages by changing our ESLint configuration to disallow relying on a global jQuery object in AMD modules. Fixes gh-4358 Closes gh-4361

* Event: Leverage native events for focus/blur/click; propagate additional dataRichard Gibson2019-03-204-24/+161
| | | | | | | | | | | | | | | | | | | | | Summary of the changes/fixes: 1. Trigger checkbox and radio click events identically (cherry-picked from b442abacbb8464f0165059e8da734e3143d0721f that was reverted before). 2. Manually trigger a native event before checkbox/radio handlers. 3. Add test coverage for triggering namespaced native-backed events. 4. Propagate extra parameters passed when triggering the click event to the handlers. 5. Intercept and preserve namespaced native-backed events. 6. Leverage native events for focus and blur. 7. Accept that focusin handlers may fire more than once for now. Fixes gh-1741 Fixes gh-3423 Fixes gh-3751 Fixes gh-4139 Closes gh-4279 Ref gh-1367 Ref gh-3494

* Build: Remove obsolete globals from ESLint configurationMichał Gołębiowski-Owczarek2019-02-191-1/+5
| | | | | We had quite a few obsolete globals declared in various ESLint config files. We also no longer allow to rely on the `noGlobal` & `jQuery` globals in the built file which is not needed. Closes gh-4301
* Core: Support passing nonce through jQuery.globalEvalMichał Gołębiowski-Owczarek2019-01-213-15/+18

* Manipulation: Respect script nomodule attribute in DOM manipulationMichał Gołębiowski-Owczarek2019-01-211-1/+1
| | | | | | | | | | | | | PR #3869 added support for `<script type="module">` & some support for the `nomodule` attribute but with no tests for `nomodule` and with the attribute only respected on inline scripts. This commit adds support for source-based scripts as well. It also adds tests for `nomodule`, including making sure legacy browsers execute such scripts as they'd natively do - that's the whole point of `nomodule` scripts, after all.

* Ajax: Fix getResponseHeader(key) for IE11Andrei Fangli2018-11-261-3/+5
| | | | | | | | | | | - getResponseHeader(key) combines all header values for the provided key into a single result where values are concatenated by ', '. This does not happen for IE11 since multiple values for the same header are returned on separate lines. This makes the function only return the last value of the header for IE11. - Updated ajax headers test to better cover Object.prototype collisions Close gh-4173 Fixes gh-3403
* Core: Recognize Shadow DOM in attachment checksSaptak Sengupta2018-11-096-15/+26

* CSS: Don't read styles.position in the width/height cssHook unless necessaryMichał Gołębiowski-Owczarek2018-10-082-4/+8
| | | | | | | | | | | | Current width/height cssHook reads the computed position style even if not necessary as the browser passes the scrollboxSize support test. That has been changed. This commit also makes the scrollboxSize support test in line with all others (i.e. only return true or false) and changes the variable name in the hook to make the code clearer. Fixes gh-4185 Closes gh-4187
