javascript - Jade conditional (if/else) to add class to div inline

Question

Is there a way to do this inline in a jade template?

if(typeof fromEdit != 'undefined')
   div#demo.collapse.in
else
   div#demo.collapse

Would like to do this conditional check "inline" and the result would add the .in to the end of the div if fromEdit exists.

Answer 1

This works:

div#demo.collapse(class=typeof fromEdit === "undefined" ? "" : "in")
