How to get data from mongo and store it in a variable in jade file

Question

I am using express.js for my application, i want to retrieve data from my mongodb and store it in a variable in my jade file, then i will use this variable to draw charts using dygraph.

 doctype html html head title siddh link(rel='stylesheet', href='/stylesheets/style.css') script(type='text/javascript', src='http://cdnjs.cloudflare.com/ajax/libs/dygraph/1.1.1/dygraph-combined.js') body #graphdiv(style="width:1000px; height=700px;") script(type='text/javascript'). each doc, i in docs 

. i am getting error in last line after each and it says "expecting newline or semicolon". And below is the javascript file for routing.

 exports.getData = function(req,res){ var db = req.db; var collection = db.get('collection'); collection.find({},{},function(e,docs){ res.render('index1.jade',{docs:docs}); }); } 

I searched the internet but i am not getting any relevant data, and as a guide for node,mongo and express i am following this tutorial : cwbuecheler.com/web/tutorials/2013/node-express-mongo/

In your docs either put _id as a string or remove that, that's an invalid json, test it at http://codebeautify.org/jsonvalidate , make it to string.

Then try this:

doctype html
html
   head
      title siddh
      link(rel='stylesheet', href='/stylesheets/style.css')
      script(type='text/javascript', src='http://cdnjs.cloudflare.com/ajax/libs/dygraph/1.1.1/dygraph-combined.js')
   body
      #graphdiv(style="width:1000px; height=700px;")
      ul
         each val,i in docs
            li= val['_id']
            li= val['Date']
            li= val['TTFB']

And if you want it in graphdiv put JavaScript code as it is, you may test it here http://jade-lang.com/
