jQuery switched to a completely new event binding implementation as of
1.7.0, centering around on/off methods instead of previous bind/unbind.
This patch makes jqLite match this implementation while still supporting
previous bind/unbind methods.
this fix ensures that we prevent the default action on form submission
(full page reload) even in cases when the form is being destroyed as
a result of the submit event handler (e.g. when route change is
triggered).
The fix is more complicated than I'd like it to be mainly because
we need to ensure that we don't create circular references between
js closures and dom elements via DOM event handlers that would then
result in a memory leak.
Also the differences between IE8, IE9 and normal browsers make testing
this ugly.
Closes#1238
the original test relied on incorrect assumptions about how jasmine async
tests work (when setTimeout is triggered) and how browser reloads a page
(the sequence of events) and thus the test passes even when the default
is not prevented.
this change fixes the test by registering an extra submit event handler
that checks if the default was prevented.
if the default was not prevented, the test will fail and the page will
be reloaded causing the test runner to panic.
It turns out that listening only on "blur" event is not sufficient in many scenarios,
especially when you use form validation you always had to use ngModelnstant
e.g. if you want to disable a button based on valid/invalid form.
The feedback we got from our apps as well as external apps is that the
ngModelInstant should be the default.
In the future we might provide alternative ways of suppressing updates
on each key stroke, but it's not going to be the default behavior.
Apps already using the ngModelInstant can safely remove it from their
templates. Input fields without ngModelInstant directive will start propagating
the input changes into the model on each key stroke.
