javascript - EJS and node not loading template correctly, res.render -

in 1 of node files, have function executing every page(simple login implementation). in code below chatbar show specific route. flow page this:

-client logs in...hits '/', , runs below function. showchatbar = false. -immediately page redirects '/chat' route. showchatbar = true. should displaying chat bar now. not.

my thoughts, that...this happens fast showchatbar=true, never gets load. maybe async problem? maybe res.render?

here node.js code

exports.login = function (req, res) { var showchatbar = false, navbutton = '', navtitle='',navsubtitle='';  if(typeof req.url !='undefined'){     if(req.url.indexof('chat')!=-1){         //consumer view         showchatbar = true;         navbutton = "close";     }      if(req.url.indexof('agent')!=-1){         //agent view         navbutton = "close";         navtitle='my clients';     } }  if(typeof req.headers.referer != 'undefined'){     if(req.headers.referer.indexof('agent')!=-1){         //agent chat view         navbutton = "back";     } }  res.render('index', {title: 'express', showchatbar: showchatbar, navbutton:navbutton, navtitle:navtitle,navsubtitle:navsubtitle}); 

};

here ejs portion:

<script>     var chatbar =<%= showchatbar %>, navbutton='<%= navbutton %>', navtitle='<%= navtitle %>',navsubtitle='<%= navsubtitle %>';  </script> 

thoughts on why not updating template correctly showchatbar = true?

try using req.originalurl instead of req.url

here's documentation it:

req.originalurl

req.url not native express property, inherited node’s http module.,

this property req.url; however, retains original request url, allowing rewrite req.url freely internal routing purposes. example, “mounting” feature of app.use() rewrite req.url strip mount point.

// /search?q=something req.originalurl // => "/search?q=something"
