There are two variants: + +`webcomponents.js` includes all of the polyfills. + +`webcomponents-lite.js` includes all polyfills except for shadow DOM. + + +## Browser Support + +Our polyfills are intended to work in the latest versions of evergreen browsers.

We cannot guarantee support for browsers outside of our compatibility matrix. + + +### Manually Building + +If you wish to build the polyfills yourself, you'll need `node` and `gulp` on your system: + + * install [node.js](http://nodejs.org/) using the instructions on their website + * use `npm` to install [gulp.js](http://gulpjs.com/): `npm install -g gulp` + +Now you are ready to build the polyfills with: + + # install dependencies + npm install + # build + gulp build + +The builds will be placed into the `dist/` directory. + +## Contribute + +See the [contributing guide](CONTRIBUTING.md) + +## License + +Everything in this repository is BSD style license unless otherwise specified. + +Copyright (c) 2015 The Polymer Authors.

This is to ensure the imports have loaded and any registered elements in them have been upgraded. + +The webcomponents.js and webcomponents-lite.js polyfills parse element definitions and handle their upgrade asynchronously. If prematurely fetching the element from the DOM before it has an opportunity to upgrade, you'll be working with an `HTMLUnknownElement`. + +For these situations (or when you need an approximate replacement for the Polymer 0.5 `polymer-ready` behavior), you can use the `WebComponentsReady` event as a signal before interacting with the element.

This means document level styles don't apply to shadow roots, and styles defined within a shadow root don't apply outside of that shadow root. [Several selectors](http://www.html5rocks.com/en/tutorials/webcomponents/shadowdom-201/) are provided to be able to deal with the shadow boundary. + +The Shadow DOM polyfill can't prevent document styles from leaking into shadow roots. It can, however, encapsulate styles within shadow roots to some extent. This behavior isn't automatically emulated by the Shadow DOM polyfill, but it can be achieved by manually using the included ShadowCSS shim: + +``` +WebComponents.ShadowCSS.shimStyling( shadowRoot, scope ); +``` + +... where `shadowRoot` is the shadow root of a DOM element, and `scope` is the name of the scope used to prefix the selectors. This removes all `<style>` elements from the shadow root, rewrites it rules using the given scope and reinserts the style as a document level stylesheet. Note that the `:host` and `:host-context` pseudo classes are also rewritten. + +For a full explanation on the implementation and both the possibilities and the limitations of ShadowCSS please view the documentation in the [ShadowCSS source](src/ShadowCSS/ShadowCSS.js). + +### Element wrapping / unwrapping limitations <a id="wrapping"></a> +The Shadow DOM polyfill is implemented by [wrapping](http://webcomponents.org/polyfills/shadow-dom/#wrappers) DOM elements whenever possible. It does this by wrapping methods like `document.querySelector` to return wrapped DOM elements. This has a few caveats: + * Not _everything_ can be wrapped. For example, elements like `document`, `window`, `document.body`, `document.fullscreenElement` and others are non-configurable and thus cannot be overridden. + * Wrappers don't support [live NodeLists](https://developer.mozilla.org/en-US/docs/Web/API/NodeList#A_sometimes-live_collection) like `HTMLElement.childNodes` and `HTMLFormElement.elements`. All NodeLists are snapshotted upon read. See [#217](https://github.com/webcomponents/webcomponentsjs/issues/217) for an explanation. + +In order to work around these limitations the polyfill provides the `ShadowDOMPolyfill.wrap` and `ShadowDOMPolyfill.unwrap` methods to respectively wrap and unwrap DOM elements manually. + +### Custom element's constructor property is unreliable <a id="constructor"></a> +See [#215](https://github.com/webcomponents/webcomponentsjs/issues/215) for background. + +In Safari and IE, instances of Custom Elements have a `constructor` property of `HTMLUnknownElementConstructor` and `HTMLUnknownElement`, respectively. It's unsafe to rely on this property for checking element types. + +It's worth noting that `customElement.__proto__.__proto__.constructor` is `HTMLElementPrototype` and that the prototype chain isn't modified by the polyfills(onto `ElementPrototype`, etc.) + +### Contenteditable elements do not trigger MutationObserver <a id="contentedit"></a> +Using the MutationObserver polyfill, it isn't possible to monitor mutations of an element marked `contenteditable`. +See [the mailing list](https://groups.google.com/forum/#!msg/polymer-dev/LHdtRVXXVsA/v1sGoiTYWUkJ) + +### ShadowCSS: :host-context(...):host(...) doesn't work <a id="hostcontext"></a> +See [#16](https://github.com/webcomponents/webcomponentsjs/issues/16) for background. + +Under the shadow DOM polyfill, rules like: +``` +:host-context(.foo):host(.bar) {...} +``` +don't work, despite working under native Shadow DOM. The solution is to use `polyfill-next-selector` like: + +``` +polyfill-next-selector { content: '.foo :host.bar, :host.foo.bar'; } +``` + +### ShadowCSS: :host(.zot:not(.bar:nth-child(2))) doesn't work <a id="nestedparens"></a> +ShadowCSS `:host()` rules can only have (at most) 1-level of nested parentheses in its argument selector under ShadowCSS. For example, `:host(.zot)` and `:host(.zot:not(.bar))` both work, but `:host(.zot:not(.bar:nth-child(2)))` does not. + +### HTML imports: document.currentScript doesn't work as expected <a id="currentscript"></a> +In native HTML Imports, document.currentScript.ownerDocument references the import document itself. In the polyfill use document._currentScript.ownerDocument (note the underscore). + +### execCommand and contenteditable isn't supported under Shadow DOM <a id="execcommand"></a> +See [#212](https://github.com/webcomponents/webcomponentsjs/issues/212) + +`execCommand`, and `contenteditable` aren't supported under the ShadowDOM polyfill, with commands that insert or remove nodes being especially prone to failure. diff --git a/catapult/third_party/polymer/components/webcomponentsjs/ShadowDOM.js b/catapult/third_party/polymer/components/webcomponentsjs/ShadowDOM.js new file mode 100644 index 00000000..51989754 --- /dev/null +++ b/catapult/third_party/polymer/components/webcomponentsjs/ShadowDOM.js @@ -0,0 +1,4496 @@ +/** + * @license + * Copyright (c) 2014 The Polymer Project Authors.
