Should handle JQLite, jQuery, NodeList and other objects like arrays
but not other generic objects or instances of user defined types
with length property.
Closes#1840
in 5ae63fd3 the comparison was made consistent but strict, so that
angular.equals({}, {foo: undefined}) // always returns false
this turns out to cause issues for data that is being roundtripped via network
and serialized via JSON because JSON.stringify serializes {foo: undefined} as {}.
Since angular.equals() behaved like this before the 5ae63fd3 in 50% of the cases,
changing the behavior in this way should not introduce any significant issues.
Closes#1648
previously:
a = {};
b = {x:undefined};
angular.equals(a, b) == angular.equals(b, a) // returns false.
both should return false because these objects are not equal.
unlike in implemented in #1695 the comparison should be stricter
and return false not true. if we need to relax this in the future
we can always do so.
Closes#1648
We have many instances of this object and we clone them as well (e.g. ng-repeat).
This should save some memory and performance as well.
Double prefixed private properties of attr object:
attr.$element -> attr.$$element
attr.$observers -> attr.$$observers
Update shallowCopy to not copy $$ properties and allow passing optional destination 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
- 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
the flag must be in all src and test files so that we get the benefit of
running in the strict mode even in jstd
the following script was used to modify all files:
for file in `find src test -name "*.js"`; do
echo -e "'use strict';\n" > temp.txt
cat $file >> temp.txt
mv temp.txt $file
done
8cad231 broke $eager services
Problem is that the injector.eager function is not invoked when a new scope
is created. Added a test to make sure service is eagerly instantiated.
Closes#403
- extend size() to take size(obj, ownPropsOnly)
- add specs for size()
- update docs to mention string support
- use size() in ng:repeat
including the hasOwnProp check for all object doesn't create
significant perf penalty:
