feat(Attributes): added support for attributes observing deregistration #5609
Conversation
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);
}
};
});

otherwise this looks good to me, but since it requires a breaking change I'm going to triage it for 1.3 |

Hi Igor. Just signed it again, but I think I have some problem with the CLA signature, as you can see in this PR. Can you help me with this CLA signature? I'll try mailing it anyway. |
