Previously we used to put callbacks on the window object, but that
causes problems on IE8 where it is not possible to delete properties
from the window object
- since NaN !== NaN in javascript digest can get into an infinite loop
when model value is set to NaN
- angular.equals(NaN, NaN) should return true since that's what we
expect when comparing primitives or objects containing NaN values
Previously NaN because of its special === properties was used as the
initial value for watches, but that results in issues when NaN is used
as model value.
In order to allow for model to be anything incuding undefined and NaN we
need to mark the initial value differently in a way that would avoid
these issues, allow us to run digest without major perf penalties and
allow for clients to determine if the listener is being called because
the watcher is being initialized or because the model changed. This
implementation covers all of these scenarios.
BREAKING CHANGE: previously to detect if the listener was called because
the watcher was being initialized, it was suggested that clients check
if old value is NaN. With this change, the check should be if the newVal
equals the oldVal.
Closes#657
- turn scope into a $rootScope service.
- injector is now a starting point for creating angular application.
- added inject() method which wraps jasmine its/beforeEach/afterEach,
and which allows configuration and injection of services.
- refactor tests to use inject() where possible
BREAK:
- removed angular.scope() method
The last script element in the dom is always us if the script that
contains angular is loaded synchronously.
For async loading manual bootstrap needs to be performed.
Close#621
Because of changes in jQuery, we need to use element().prop() instead of element().attr() to retrieve className and other element properties.
Additionally all attribute selectors (e.g. input[name=value]) must have value quoted if it contains dots (".").
it turns out that even with our tricks, jqLite#show is not usable in
practice and definitely not on par with jQuery. so rather than
introducing half-baked apis which introduce issues, I'm removing them.
I also removed show/hide uses from docs, since they are not needed.
Breaks jqLite.hide/jqLite.show which are no longer available.
- Speed improvements (about 4x on flush phase)
- Memory improvements (uses no function closures)
- Break $eval into $apply, $dispatch, $flush
- Introduced $watch and $observe
Breaks angular.equals() use === instead of ==
Breaks angular.scope() does not take parent as first argument
Breaks scope.$watch() takes scope as first argument
Breaks scope.$set(), scope.$get are removed
Breaks scope.$config is removed
Breaks $route.onChange callback has not "this" bounded
