To create a button that requires a second confirmation step, assign it the

Required:
|

data-onclick: String that would normally be the button's onclick.
|

This is done so that if the button_with_confirm fails to initialize,
|

the button will be non-operational as opposed to being operational
|
|
but with no confirmation. For dangerous actions I think this is a
|
|
worthwhile move though it could lead to feature downtime.

|
Optional:
|

data-prompt: Text that appears next to the confirm button. Default is
|
|
"Are you sure?".
|
|
data-prompt-class
|
|
|
|
data-confirm: Text inside the confirm button. Default is to inherit the
|
|
original button's text.

data-confirm-class

data-cancel: Text inside the cancel button. Default is "Cancel".
