javascript - How to toggle a view inside of a region in Marionette? -

i'm looking better equivalent of:

if (view.myregion.currentview) {     view.myregion.reset(); } else {     var myotherview = new marionette.itemview();     view.myregion.show(myotherview); } 

i went through docs, didn't find similar unfortunately.

from docs - showing view on marionette site, under preventdestroy section,

if replace current view new view calling show, default automatically destroy previous view.

so perhaps, helpful you. region manager automatically destroy existing view being held region , render new one.

if there's specific @ time of destroy, believe can write ondestroy callback view.
