By default, any change to an input will trigger an immediate model update,
form validation and run a $digest. This is not always desirable, especially
when you have a large number of bindings to update.
This PR implements a new directive `ngModelOptions`, which allow you to
override this default behavior in several ways. It is implemented as an
attribute, to which you pass an Angular expression, which evaluates to an
**options** object.
All inputs, using ngModel, will search for this directive in their ancestors
and use it if found. This makes it easy to provide options for a whole
form or even the whole page, as well as specifying exceptions for
individual inputs.
* You can specify what events trigger an update to the model by providing
an `updateOn` property on the **options** object. This property takes a
string containing a space separated list of events.
For example, `ng-model-options="{ updateOn: 'blur' }"` will update the
model only after the input loses focus.
There is a special pseudo-event, called "default", which maps to the
default event used by the input box normally. This is useful if you
want to keep the default behavior and just add new events.
* You can specify a debounce delay, how long to wait after the last triggering
event before updating the model, by providing a `debounce` property on
the **options** object.
This property can be a simple number, the
debounce delay for all events. For example,
`ng-model-options="{ debounce: 500 }" will ensure the model is updated
only when there has been a period 500ms since the last triggering event.
The property can also be an object, where the keys map to events and
the values are a corresponding debounce delay for that event.
This can be useful to force immediate updates on some specific
circumstances (like blur events). For example,
`ng-model-options="{ updateOn: 'default blur', debounce: { default: 500, blur: 0} }"`
This commit also brings to an end one of the longest running Pull Requests
in the history of AngularJS (#2129)! A testament to the patience of @lrlopez.
Closes#1285, #2129, #6945
With 1.2.x, `$animate.enter` and `$animate.move` both insert the element at the end of the provided
parent container element when only the `parent` element is provided. If an `after` element is provided
then they will place the inserted element after that one. This works fine, but there is no way to
place an item at the top of the provided parent container using these two APIs.
With this change, if the `after` argument is not specified for either `$animate.enter` or `$animate.move`,
the new child element will be inserted into the first position of the parent container element.
Closes#4934Closes#6275
BREAKING CHANGE: $animate will no longer default the after parameter to the last element of the parent
container. Instead, when after is not specified, the new element will be inserted as the first child of
the parent container.
To update existing code, change all instances of `$animate.enter()` or `$animate.move()` from:
`$animate.enter(element, parent);`
to:
`$animate.enter(element, parent, angular.element(parent[0].lastChild));`
The default CSS driver in ngAnimate directly uses node.className when reading
the CSS class string on the given element. While this works fine with standard
HTML DOM elements, SVG elements have their own DOM property. By switching to use
node.getAttribute, ngAnimate can extract the element's className value without
throwing an exception.
When using jQuery over jqLite, ngAnimate will not properly handle SVG elements
for an animation. This is because jQuery doesn't process SVG elements within it's
DOM operation code by default. To get this to work, simply include the jquery.svg.js
JavaScript file into your application.
Closes#6030
When a async task interacts with a scope that has been destroyed already
and if it interacts with a property that is prototypically inherited from
some parent scope then resetting proto would make these inherited properties
inaccessible and would result in NPEs
The basic approach is to introduce a new elt.data() called $classCounts that keeps
track of how many times ngClass, ngClassEven, or ngClassOdd tries to add a given class.
The class is added only when the count goes from 0 to 1, and removed only when the
count hits 0.
To avoid duplicating work, some of the logic for checking which classes
to add/remove move into this directive and the directive calls $animate.
Closes#5271
Due to a known V8 memory leak[1] we need to perform extra cleanup to make it easier
for GC to collect this scope object.
V8 leaks are due to strong references from optimized code (fixed in M34) and inline
caches (fix in works). Inline caches are caches that the virtual machine builds on the
fly to speed up property access for javascript objects. These caches contain strong
references to objects so under certain conditions this can create a leak.
The reason why these leaks are extra bad for Scope instances is that scopes hold on
to ton of stuff, so when a single scope leaks, it makes a ton of other stuff leak.
This change removes references to objects that might be holding other big
objects. This means that even if the destroyed scope leaks, the child scopes
should not leak because we are not explicitly holding onto them.
Additionally in theory we should also help make the current scope eligible for GC
by changing properties of the current Scope object.
I was able to manually verify that this fixes the problem for the following
example app: http://plnkr.co/edit/FrSw6SCEVODk02Ljo8se
Given the nature of the problem I'm not 100% sure that this will work around
the V8 problem in scenarios common for Angular apps, but I guess it's better
than nothing.
This is a second attempt to enhance the cleanup, the first one failed and was
reverted because it was too aggressive and caused problems for existing apps.

Previously, the jqLite constructor was limited and would be unable to circumvent many of the HTML5
spec's "allowed content" policies for various nodes. This led to complicated and gross hacks around
this in the HTML compiler.
This change refactors these hacks by simplifying them, and placing them in jqLite rather than in
$compile, in order to better support these things, and simplify code.
While the new jqLite constructor is still not even close to as robust as jQuery, it should be more
than suitable enough for the needs of the framework, while adding minimal code.

Previously, constant numbers with a unary minus sign were not treated as constants. This fix corrects
this behaviour, and may provide a small performance boost for certain applications, due to constant
watches being automatically unregistered after their first listener call.

$animate attempts places a `transition: none 0s` block on the element when
the first CSS class is applied if a transition animation is underway. This
works fine for structural animations (enter, leave and move), however, for
class-based animations, this poses a big problem. As of this patch, instead
of $animate placing the block, it is now the responsibility of the user to
place `transition: 0s none` into their class-based transition setup CSS class.
This way the animation will avoid all snapping and any will allow $animate to
play nicely with class-based transitions that are defined outside of ngAnimate.
Closes#6674Closes#6739
BREAKING CHANGE: Any class-based animation code that makes use of transitions
and uses the setup CSS classes (such as class-add and class-remove) must now
provide a empty transition value to ensure that its styling is applied right
away. In other words if your animation code is expecting any styling to be
applied that is defined in the setup class then it will not be applied
"instantly" default unless a `transition:0s none` value is present in the styling
for that CSS class. This situation is only the case if a transition is already
present on the base CSS class once the animation kicks off.
If a JS animation is run before a CSS animation then the JS animation may end up writing style
data to the element. If any transition or animation style data is written then it may end up
being accidentally inherited into the CSS animation hanlder that ngAnimate uses. This may result
in an unexpected outcome due to the tweaks and hacks that the CSS handler places on the element.
If the CSS animation is run before the JS animation then, if there are no transitions on the style
attribute nor within the global CSS on the page then nothing will happen and the JS animation can
work as expected.

fb6062fb9d implements a
fix for NaN values causing $watchCollection to throw an infdig error. This change updates the test
by adding an assertion which explains what is actually being tested a bit better, and may also
provide better information in the event that the test ever fails.
Closes#6758
$watchCollection checks if oldValue !== newValue which does not work for NaN. This was causing
infinite digest errors, since comparing NaN to NaN in $watchCollection would always return false,
indicating that a change was occuring on each loop.
This fix adds a simple check to see if the current value and previous value are both NaN, and
if so, does not count it as a change.
Closes#4605
In some specific timezones and operating systems, it seems that
getTimezoneOffset() can return an incorrect value for negative timestamps, as
described in #5017. While this isn't something easily fixed in the mock code,
the tests can avoid that particular timeframe by using a positive timestamp.

In Firefox, hovering over an option in an open select menu updates the selected property of option
elements. This means that when a render is triggered by the digest cycle, and the list of options
is being rendered, the selected properties are reset to the values from the model and the option
hovered over changes. This fix changes the code to only use DOM elements' selected properties in a
comparison when a change event has been fired. Otherwise, the internal new and existing option
arrays are used.

The orderBy filter now allows string predicates passed to the orderBy filter to make use property
name predicates containing non-ident strings, such as spaces or percent signs, or non-latin
characters.
This behaviour requires the predicate string to be double-quoted.
In markup, this might look like so:
```html
<div ng-repeat="item in items | orderBy:'\"Tip %\"'">
...
</div>
```
Or in JS:
```js
var sorted = $filter('orderBy')(array, ['"Tip %"', '-"Subtotal $"'], false);
```

Previously, non-string values stored in $cookies would be removed, without warning the user, and
causing difficulty debugging. Now, the value is converted to string before being stored, and the
value is not dropped. Serialization may be customized using the toString() method of an object's
prototype.

Closes#6302
This change brings Angular's JSONP behaviour closer in line with jQuery's. It will no longer treat
a callback called with no data as an error, and will no longer support IE8 via the onreadystatechanged
event.
BREAKING CHANGE:
Previously, the JSONP backend code would support IE8 by relying on the readystatechanged events. This
is no longer the case, as these events do not provide adequate useful information for deeming whether
or not a response is an error.
Previously, a JSONP response which did not pass data into the callback would be given a status of -2,
and treated as an error. Now, this situation will instead be given a status of 200, despite the lack
of data. This is useful for interaction with certain APIs.
Previously, the onload and onerror callbacks were added to the JSONP script tag. These have been
replaced with jQuery events, in order to gain access to the event object. This means that it is now
difficult to test if the callbacks are registered or not. This is possible with jQuery, using the
$.data("events") method, however it is currently impossible with jqLite. This is not expected to
break applications.
Closes#4987Closes#6735
It's now possible to pass a function to match the URL in $httpBackend mocked
expectations. This gives a more sophisticate control over the URL matching
without requiring complex RegExp mantainance or the workaround of creating
an object with a `test` function in order to mimic RegExp interface.
This approach was suggested in [this
thread](https://groups.google.com/d/msg/angular/3QsCUEvvxlM/Q4C4ZIqNIuEJ)
Closes#4580
In order to make the behavior compatible with $rootScope.$watch and $rootScope.$on methods, and
make it possible to deregister an attribute observer, Attributes.$observe method now returns a
deregistration function instead of the observer itself.
BREAKING CHANGE: calling attr.$observe no longer returns the observer function, but a
deregistration function instead.
To migrate the code follow the example below:
Before:
```
directive('directiveName', function() {
return {
link: function(scope, elm, attr) {
var observer = attr.$observe('someAttr', function(value) {
console.log(value);
});
}
};
});
```
After:
```
directive('directiveName', function() {
return {
link: function(scope, elm, attr) {
var observer = function(value) {
console.log(value);
};
attr.$observe('someAttr', observer);
}
};
});
```
Closes#5609
Originally we destroyed the oldValue by incrementaly copying over portions of the newValue
into the oldValue during dirty-checking, this resulted in oldValue to be equal to newValue
by the time we called the watchCollection listener.
The fix creates a copy of the newValue each time a change is detected and then uses that
copy *the next time* a change is detected.
To make `$watchCollection` behave the same way as `$watch`, during the first iteration
the listener is called with newValue and oldValue being identical.
Since many of the corner-cases are already covered by existing tests, I refactored the
test logging to include oldValue and made the tests more readable.

```
// do work
expect(log.empty()).toEqual(['bar']);

PR #5547 introduced conversion of all 0 status codes to 404 for cases
where no response was recieved (previously this was done for the
file:// protocol only). But this mechanism is too eager and
masks legitimate cases where status 0 should be returned. This commits
reverts to the previous mechanism of handling 0 status code for the
file:// protocol (converting 0 to 404) while retaining the returned
status code 0 for all the protocols other than file://

Add css animations when form or field status change to/from dirty,
pristine, valid or invalid. This works like animation system present
with ngClass, ngShow, etc.
Closes#5378
Transitions must be blocked so that the initial CSS class can be applied
without triggering an animation. Keyframes do not need to be blocked since
animations are always triggered on the starting CSS class, however, if a
stagger animation is set to occur then all elements for index > 0 should
be blocked. This is to prevent the animation from occuring early on before
the stagger delay for the given element has passed.
With ngAnimate and keyframe animations, IE10 and Safari will render a slight
flicker effect caused by the blocking. This fix resolves this issue.
Closes#4225
