angularjs - Cancel angular bootstrap modal dimiss on backdrop click -

i want modal dismissable if backdrop clicked, if form in side dirty want able cancel dismiss, possible?

this possible setting backdrop: 'static'.

backdrop - controls presence of backdrop. allowed values: true (default), false (no backdrop), static - backdrop present modal window not closed when clicking outside of modal window.

afterwards add click handler div:

$('div.modal.fade').on('click', function() {     // close or dismiss modal });
