ruby on rails - Include route helpers in javascript files -

i'm trying log route's root url console:

app/assets/javascripts/foo.js.erb:

console.log(<%= root_path %>);

however, gives me error in javascript console:

uncaught syntaxerror: invalid regular expression: missing /

how include route helpers javascript files?

worth noting can no problem:

console.log(<%= pi = "3.142" %>); //-> 3.142

however, there weird error when effort set letters string:

console.log(<%= pi = "3.142t" %>); //-> uncaught syntaxerror: unexpected token illegal

i need able log strings letters in if want have route helpers working! :)

erb beingness parsed on server side, before javascript has chance read it. when executed on browser read:

console.log(http://root_url.com);

you can see, missing quotes here. try:

console.log('<%= root_url %>');
