This function handles events for any UI that looks like
|
|
this:
|
|
|
|
[pill-enabled input box for subscribers] [Add button]
|
|
|
|
In an ideal world the above two widgets would be enclosed in
|
|
a <form>...</form> section and we would have a single submit
|
|
handler, but our current implementation of input pills has
|
|
some magic that prevents the pills from playing nice with
|
|
the vanilla HTML form/submit mechanism.
|
|
|
|
So, instead, we provide this helper function to manage
|
|
the two events needed to make it look like the widgets
|
|
are inside an actual HTML <form> tag.
|
|
|
|
This abstraction also automatically retrieves the user_ids
|
|
from the input pill and sends them back to the `action`
|
|
function passed in.
|
|
|
|
The subscriber input-pill widgets lets you provide
|
|
user_ids by creating pills for either:
|
|
|
|
* single user
|
|
* user group
|
|
* stream (i.e. subscribed users for the stream)
