Remove reference to `employee` property as it's not used in the example.
Inject and use `$rootScope` applying `department` property as mentioned in text.
Closes#4839
The CSS styling in the ng-scope demo was using CSS classes (`.doc-example-live` and
`.show-scope') to prevent the styling for the demo from affecting the entire page.
Unfortunately elements containing these classes did not appear in JSFiddle or Plunker
when you click edit.
This fix moves the `.show-scope' class inside the demo (renaming it `.show-scope-demo`)
and removes the reliance on `.doc-example-live` altogether.
Closes#4838
params and paramDefaults support looking up the parameter value from the
data object. The syntax for that is `@nested.property.name`.
Currently, $resource uses $parse to do this. This is too liberal
(you can use values like `@a=b` or `@a | filter` and have it work -
which doesn't really make sense). It also puts up a dependency on
$parse which is has restrictions to secure expressions used in
templates. The value here, though a string, is specified in Javascript
code and shouldn't have those restrictions.
This refactors the filter guide docs into a single file.
Also removes out of date references to the fact that Angular used to enhance Arrays while evaluating expressions.
Before, there we multiple overview docs:
- guide/overview
- guide/introduction
- guide/dev_guide.mvc
- guide/dev_guide.mvc.understanding_model
- guide/dev_guide.mvc.understanding_view
- guide/concepts
Now we have:
- guide/introduction: High level description of Angular with the key benefits but without code or any concrete concepts
- guide/concepts: explains all important concepts with a simple example and contains deep links to the other parts of the guide.
All the old information was moved into existing documents or deleted when they were duplicates.
The example about transclusion and scopes worked only because the order of `scope` and `element`
arguments is wrong, which means that the `name' property of the scope is not really being updated.
To really work, the directive has to define its own scope, either a new child scope or, as is more
common with transclusion, an isolated scope.
Closes#4774
BREAKING CHANGE:
This commit introduces the notion of "private" properties (properties
whose names begin and/or end with an underscore) on the scope chain.
These properties will not be available to Angular expressions (i.e. {{
}} interpolation in templates and strings passed to `$parse`) They are
freely available to JavaScript code (as before).
Motivation
----------
Angular expressions execute in a limited context. They do not have
direct access to the global scope, Window, Document or the Function
constructor. However, they have direct access to names/properties on
the scope chain. It has been a long standing best practice to keep
sensitive APIs outside of the scope chain (in a closure or your
controller.) That's easier said that done for two reasons: (1)
JavaScript does not have a notion of private properties so if you need
someone on the scope chain for JavaScript use, you also expose it to
Angular expressions, and (2) the new "controller as" syntax that's now
in increased usage exposes the entire controller on the scope chain
greatly increaing the exposed surface. Though Angular expressions are
written and controlled by the developer, they (1) typically deal with
user input and (2) don't get the kind of test coverage that JavaScript
code would. This commit provides a way, via a naming convention, to
allow publishing/restricting properties from controllers/scopes to
Angular expressions enabling one to only expose those properties that
are actually needed by the expressions.
If you have zoomed into the page in your browser then the screen coordinate system no longer
matches the page coordinate system. To ensure that dragged elements work correctly when zoomed
we should use pageX/pageY rather than screenX/screenY.
