* Build: Followups after introducing ES modules compiled via RollupMichał Gołębiowski-Owczarek2020-05-056-17/+9
| | | | | | | | | | This commit cleans up a few comments & configurations that are out of date after the migration to ES modules backed by a Rollup-based compilation. Also, de-indent AMD modules. This will preserve a more similar structure to the one on 3.x-stable where the body of the main `define` wrapper is not indented. Closes gh-4705
* CSS: Include `show`, `hide` & `toggle` methods in the jQuery slim buildMichał Gołębiowski-Owczarek2020-05-052-5/+1
| | | | | | | | | | | | The `show()`, `hide()` & `toggle()` methods were included in the 3.x jQuery slim build. The jQuery master build accidentally started to exclude them as they were only imported in the effects module and the new Rollup-based build system follows the module dependency graph when excluding modules. To resolve the issue, import the `css/showHide.js` file directly in the main `jquery.js` file. Closes gh-4704 Ref jquery/jquery-migrate#346
* Build: Correct code indentations based on jQuery Style GuideWonseop Kim2020-05-0516-42/+60
| | | | | | | | 1. Correct code indentations based on jQuery Style Guide (contribute.jquery.org/style-guide/js/#spacing). 2. Add rules to "src/.eslintrc.json" to enable "enforcing consistent indentation", with minimal changes to the current code. Closes gh-4672
* Tests: Workaround failures in recent XSS tests in iOS 8 - 12Michał Gołębiowski-Owczarek2020-04-301-7/+15
| | | | | | | iOS 8-12 parses `<noembed>` tags differently, executing this code. This is no different to native behavior on that OS, though, so just accept it. Ref gh-4685 Closes gh-4694

* Build: Reduce the slim build header comment & jQuery.fn.jqueryMichał Gołębiowski-Owczarek2020-04-271-21/+36
| | | | | | | | | | | | | | | | | | | | | | | So far, the slim build was expanded to its full exclusion list, generating the following `jQuery.fn.jquery`: ``` v4.0.0-pre -ajax,-ajax/jsonp,-ajax/load,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-deprecated/ajax-event-alias,-callbacks,-deferred,-deferred/exceptionHook,-effects,-effects/Tween,-effects/animatedSelector,-queue,-queue/delay,-core/ready ``` This commit changes it to just `v4.0.0-pre slim`. Only the pure slim build is treated this way, any modification to it goes through the old expansion; e.g. for `custom:slim,-deprecated` we get the following `jQuery.fn.jquery`: ``` v4.0.0-pre -deprecated,-deprecated/ajax-event-alias,-deprecated/event,-ajax,-ajax/jsonp,-ajax/load,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-callbacks,-deferred,-deferred/exceptionHook,-effects,-effects/Tween,-effects/animatedSelector,-queue,-queue/delay,-core/ready ``` Since the version string is also put in the jQuery header comment, it also got smaller. Also, the logic to skip including the commit hash in the header comment - when provided through the COMMIT environment variable which we do in Jenkins - in minified builds headers has been applied to builds with exclusions as well. Closes gh-4649
* Tests: Use only one focusin/out handler per matching window & documentMichał Gołębiowski-Owczarek2020-04-271-9/+54
| | | | | | | | | | | | | | | | | | | Backport tests from a jQuery 3.x fix that's not needed on `master`. Also, fix the "focusin from an iframe" test to actually verify the behavior from commit 1cecf64e5aa415367a7dae0b55c2dd17b591442d - the commit that introduced the regression - to make sure we don't regress on either front. The main part of the modified test was checking that focusin handling in an iframe works and that's still checked. The test was also checking that it doesn't propagate to the parent document, though, and, apparently, in IE it does. This one test is now blacklisted in IE.

* Build: Move ESLint max-len disable-directive to dist/.eslintrc.jsonEd S2020-04-272-2/+3
| | | | | | | This disable-directive only applies to the built version, so put it in /dist. This avoids a warning about an unused directive in the source version. Closes gh-4676
* Tests: Fix flakiness in the "jQuery.ajax() - JSONP - Same Domain" testMichał Gołębiowski-Owczarek2020-04-271-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "jQuery.ajax() - JSONP - Same Domain" test is firing a request with a duplicate "callback" parameter, something like (simplified): ``` mock.php?action=jsonp&callback=jQuery_1&callback=jQuery_2 ``` There was a difference in how the PHP & Node.js implementations of the jsonp action in the mock server handled situations like that. The PHP implementation was using the latest parameter while the Node.js one was turning it into an array but the code didn't handle this situation. Because of how JavaScript stringifies arrays, while the PHP implementation injected the following code: ```js jQuery_2(payload) ``` the Node.js one was injecting the following one: ```js jQuery_1,jQuery_2(payload) ``` This is a comma expression in JavaScript; it so turned out that in the majority of cases both callbacks were identical so it was more like: ```js jQuery_1,jQuery_1(payload) ``` which evaluates to `jQuery_1(payload)` when `jQuery_1` is defined, making the test go as expected. In many cases, though, especially on Travis, the callbacks were different, triggering an `Uncaught ReferenceError` error & requiring frequent manual re-runs of Travis builds. This commit fixes the logic in the mock Node.js server, adding special handling for arrays. Closes gh-4687

* Data:Event:Manipulation: Prevent collisions with Object.prototypeMichał Gołębiowski-Owczarek2020-03-026-9/+69
| | | | | | | Make sure events & data keys matching Object.prototype properties work. A separate fix for such events on cloned elements was added as well. Fixes gh-3256 Closes gh-4603
* Release: Use an in-repository dist README fixtureMichał Gołębiowski-Owczarek2020-03-023-63/+132
| | | | | | | | | | Use a dist README fixture kept in the jQuery repository instead of modifying an existing one. This makes the jQuery repository the single source of truth when it comes to jQuery releases and it makes it easier to make changes to README without worrying how it will affect older jQuery lines. The commit also ES6ifies build/release.js & build/release/dist.js Closes gh-4614
* Build: Enable ESLint one-var rule for var declarations in browser codeMichał Gołębiowski-Owczarek2020-03-025-6/+10
| | | | | | | Node.js code is written more & more commonly in ES6+ so it doesn't make sense to enable it there. There are many violations in test code so it's disabled there as well. Closes gh-4615
* Tests: Pass a number of necessary done() calls to assert.async()Michał Gołębiowski-Owczarek2020-03-022-10/+10
| | | | | | It is no longer needed to create `done` wrappers in tests that require multiple async operations to complete. Closes gh-4633

* Core: Fire iframe script in its context, add doc param in globalEvalMichał Gołębiowski-Owczarek2020-02-108-10/+74
| | | | | | | | | | 1. Support passing custom document to jQuery.globalEval; the script will be invoked in the context of this document. 2. Fire external scripts appended to iframe contents in that iframe context; this was already supported & tested for inline scripts but not for external ones. Fixes gh-4518 Closes gh-4601
* Event: remove jQuery.event.globalMichał Gołębiowski-Owczarek2020-02-102-6/+0
| | | | | | | jQuery.event.global has been write-only in the jQuery source for the past few years; reading from it was removed in c2d6847de09a52496f78baebc04f317e11ece6d2 when fixing the trac-12989 bug. Closes gh-4602
* Docs: Remove a mention of the event/alias.js module from READMEMichał Gołębiowski-Owczarek2020-01-271-1/+1
| | | | | | | The file contents now lie in deprecated/event.js so the README reference is no longer correct. Ref gh-4572 Closes gh-4599
* Build: Lint the minified jQuery file as well - a Gruntfile fixMichał Gołębiowski-Owczarek2020-01-271-1/+1
| | | | | | | | While we have absolutely no style-related expectations to our minified file, we do care that it's valid ES 5.1. This is now verified. Fixes gh-3075 Ref gh-4594 Closes gh-4598
* Ajax: Deprecate AJAX event aliases, inline event/alias into deprecatedMichał Gołębiowski-Owczarek2020-01-217-52/+50
| | | | | | | | A new `src/deprecated` directory makes it possible to exclude some deprecated APIs from a custom build when their respective "parent" module is excluded without keeping that module outside of the `src/deprecated` directory or the `src/deprecated.js` file. Closes gh-4572
* CSS: Remove the opacity CSS hookMichał Gołębiowski-Owczarek2020-01-211-12/+1
| | | | | | | | The consequence is `.css( "opacity" )` will now return an empty string for detached elements in standard-compliant browsers and "1" in IE & the legacy Edge. That behavior is shared by most other CSS properties which we're not normalizing either. Closes gh-4593
* Build: Lint the minified jQuery file as wellMichał Gołębiowski-Owczarek2020-01-212-8/+14
| | | | | | | While we have absolutely no style-related expectations to our minified file, we do care that it's valid ES 5.1. This is now verified. Fixes gh-3075 Closes gh-4594
* Build: Add intuitive names to Travis jobsMichał Gołębiowski-Owczarek2020-01-201-12/+12
| | | | | | Otherwise it's hard to see at a glance that a particular job is running on Firefox ESR, for example. Closes gh-4596
* Core: Exclude callbacks & deferred modules in the slim build as wellMichał Gołębiowski-Owczarek2020-01-201-1/+1
| | | | | | | | | | | So far, the slim build only excluded ajax & effects modules. As many web apps right now rely on native Promises, often with a polyfill for legacy browsers, deferred & callbacks modules are not that useful for sites that already exclude ajax & effects modules. This decreases the gzipped minified size of the slim module by 1760 bytes, to 19706 bytes (below 20k!). Closes gh-4553
* Attributes: Refactor val(): don't strip carriage return, isolate IE workaroundsMichał Gołębiowski-Owczarek2020-01-132-22/+70
| | | | | | | | | | Before this change, `val()` was stripping out carriage return characters from the returned value. No test has relied on that. The logic was different for option elements as its custom defined hook was omitting this stripping logic. This commit gets rid of the carriage return removal and isolates the IE-only select val getter to be skipped in other browsers. Closes gh-4585
* Tests: Remove obsolete jQuery data testsMichał Gołębiowski-Owczarek2020-01-134-115/+0
| | | | | The tests relied on `jQuery.cache` so they only ever worked in jQuery 1.x. Closes gh-4586
* Attributes: Don't set the type attr hook at all outside of IEMichał Gołębiowski-Owczarek2020-01-131-17/+18
| | | | | This removes a needless function call in modern browsers. Closes gh-4587
* Build: Make dev mode work in Karma again, serve source files from diskMichał Gołębiowski-Owczarek2020-01-082-15/+43
| | | | | | | | | | | | | | | | | | PR gh-4550 added support for running ES modules & AMD tests via Karma. This required reading the `esmodules` & `amd` props from both `QUnit.config` & `QUnit.urlParams`. By picking these two properties manually, the `dev` one stopped being respected while ones handled directly by QUnit were fine (like `hidepassed`). Instead of maintaining the full list of options, the code now iterates over QUnit URL config and handles the fallbacks in a more generic way. Apart from that, all jQuery source & test files are now read directly from disk instead of being cached by Karma so that one can run `grunt karma:chrome-debug` & work on a fix without restarting that Karma run after each change. A similar effect could have been achieved by setting `autoWatch` to `true` but then the main Karma page runs tests in an iframe by default when `grunt karma:chrome-debug` is run instead of relying on the current debug flow. Closes gh-4574 Ref gh-4550
* Build:Tests: Fix custom build tests, verify on Travis Michał Gołębiowski-Owczarek2020-01-0726-84/+174
| | | | | | | | | | | This commit fixes unit tests for the following builds: 1. The no-deprecated build: `custom:-deprecated` 2. The current slim build: `custom:-ajax,-effects` 3. The future (#4553) slim build: `custom:-ajax,-callbacks,-deferred,-effects` It also adds separate Travis jobs for the no-deprecated & slim builds. Closes gh-4577

* Build: Auto-convert sources to AMDMichał Gołębiowski-Owczarek2019-12-0910-16/+91
| | | | | | | | | | | | | | | jQuery source has been migrated in gh-4541 from AMD to ES modules. To maintain support for consumers of our AMD modules, this commits adds a task transpiling the ES modules sources in `src/` to AMD in `amd/`. A "Load with AMD" checkbox was also restored to the QUnit setup. Note that, contrary to jQuery 3.x, AMD files need to be generated via `grunt amd` or `grunt` as sources are not authored in ECMAScript modules. To achieve a similar no-compile experience during jQuery 4.x testing, use the new "Load as modules" checkbox which works in all supported browsers except for IE & Edge (the legacy, EdgeHTML-based one). Ref gh-4541 Closes gh-4554
* Event: Only attach events to objects that accept data - for realMichał Gołębiowski-Owczarek2019-12-092-2/+12
| | | | | | | | | | There was a check in jQuery.event.add that was supposed to make it a noop for objects that don't accept data like text or comment nodes. The problem was the check was incorrect: it assumed `dataPriv.get( elem )` returns a falsy value for an `elem` that doesn't accept data but that's not the case - we get an empty object then. The check was changed to use `acceptData` directly. Fixes gh-4397 Closes gh-4558
* Docs: Change OS X to macOS in READMEChristian Oliff2019-12-031-1/+1
| | | | | macOS has been around for long enough to update the naming here. Closes gh-4552
* Build: Fix the Windows buildMichał Gołębiowski-Owczarek2019-12-023-18/+51
| | | | | | | This commit gets rid of rollup-plugin-hypothetical in favor of a simpler inline Rollup plugin that fits our need and is compatible with Windows. Fixes gh-4548 Closes gh-4549
* Build: Require extensions for ES6 imports, prevent import cyclesMichał Gołębiowski-Owczarek2019-11-252-0/+8
| | | | | | | | | | | | | | | | jQuery source is now authored in ECMAScript modules. Native browser support for them requires full file names including extensions. Rollup works even if import paths don't specify extensions, though, so one import slipped through without such an extension, breaking native browser import of src/jquery.js. A new ESLint rule using eslint-plugin-import prevents us from regressing on that front. Also, eslint-plugin-import's no-cycle rule is used to avoid import cycles. Closes gh-4544 Ref gh-4541 Ref 075320149ae30a5c593c06b2fb015bdf033e0acf

* Selector: Make empty attribute selectors work in IE againMichał Gołębiowski-Owczarek2019-11-187-9/+39
| | | | | | | | | | qSA in IE 11/Edge often (but not always) don't find elements with an empty name attribute selector (`[name=""]`). Detect that & fall back to Sizzle traversal. Interestingly, IE 10 & older don't seem to have the issue. Fixes gh-4435 Closes gh-4510
* Core: Migrate from AMD to ES modules 🎉Michał Gołębiowski-Owczarek2019-11-18124-1324/+801
| | | | | | | | | | | | | | | | | | | | | | Migrate all source AMD modules to ECMAScript modules. The final bundle is compiled by a custom build process that uses Rollup under the hood. Test files themselves are still loaded via RequireJS as that has to work in IE 11. Tests can now be run in "Load as modules" mode which replaces the previous "Load with AMD" option. That option of running tests doesn't work in IE and Edge as it requires support for dynamic imports. Some of the changes required by the migration: * check `typeof` of `noGlobal` instead of using the variable directly as it's not available when modules are used * change the nonce module to be an object as ECMASscript module exports are immutable * remove some unused exports * import `./core/parseHTML.js` directly in `jquery.js` so that it's not being cut out when the `ajax` module is excluded in a custom compilation Closes gh-4541
