Using `display: none` on the `<h1>` causes `innerText` to not work as expected
and include the icon ligature (`link`) in the title. This caused the window
title on the angular.io Home page to appear as "Angular - link".
This commit fixes it by not generating anchors at all for headings with the
`no-anchor` class.
Fixes#20427
PR Close#20440
The window title is derived based on the current document's `<h1>` heading. Such
headings may contain hidden/non-visible content (e.g. textual name of font
ligatures: `<i class="material-icons">link</i>`) that should not be included in
the title.
This commit fixes this by using `innerText` (instead of `textContent`) to
extract the visible text from the `<h1>` heading. It will still fall back to
`textContent` on browsers that do not support `innerText` (e.g. Firefox 44).
Fixes#17732
By reflex we began all component tests with an async `beforeEach` that called `compileComponents`.
In at least one case (`live-example.component.spec.ts`) that led to the `it` tests being async as well.
There is no need to call `.compileComponents` because CLI web pack + plugin inlines all templates and styles.
While `.compileComponents` was harmless, it added complexity and distraction which we should not inflict on future readers and testers.
Dgeni is now providing the `id` for all the documents to be viewed. So we
no longer need to add this to the DocumentContents object.
There are some notable changes in the refactoring:
`DocumentService`:
* The id of the document to render is now obtained from `LocationService.path()`.
* The `getFileNotFoundDoc` and `getErrorDoc` methods have been extracted from
the `fetchDocument` method.
`AppComponent`:
* the `pageId` is now computed in a separate `setPageId` method.
`AppComponen` spec file:
* The `TestHttp` has had the hard coded documents removed and replaced with
a function that will generate docs as needed.
Previously, the `AppComponent.pageId` was set via the current URL, rather than
the document being displayed. This is only really noticeable when the URL does not
match a valid doc and we are actually displaying a 404 page.
Now we compute the `pageId` from the URL of the document being viewed,
which is returned from the `DocumentService.currentDocument` observable instead.
