This module makes it really easy to create are-you-sure dialogs for dangerous operations. Basically it's one function with five parameters. You give three chunks of HTML, a callback function, and a parent container. The first use of this will be in settings_user_groups, coming up in a couple commits.

/*
|
|
Look for confirm_dialog in settings_user_groups
|
|
to see an example of how to use this widget. It's
|
|
pretty simple to use!
|
|
|
|
Some things to note:
|
|
|
|
1) We create DOM on the fly, and we remove
|
|
the DOM once it's closed.
|
|
|
|
2) We attach the DOM for the modal to conf.parent,
|
|
and this temporary DOM location will influence
|
|
how styles work.
|
|
|
|
3) The cancel button is driven by bootstrap.js.
|
|
|
|
4) For settings, we have a click handler in settings.js
|
|
that will close the dialog via overlays.close_active_modal.
|
|
|
|
5) We assume that since this is a modal, you will
|
|
only ever have one confirm dialog active at any
|
|
time.
