i have value of a variable in jade template above

i have used it's incorrect syntax(((( how can it? thanks!

this depends on whether writing client side or server side javascript.

from can tell writing client-side.. in case #{ } less applicable. standard dom - manipulation may best approach here...

var h3 = document.getelementsbytagname('h3'); h3.innerhtml = 

since ajax call though, may need return a in object literal notation.

response {variableofchoice: a} #{variableofchoice}

this straight javascript, applying same method in jquery syntax should work.
