Rails - Jan 2013 - rails datatables refresh javascript

Hi

I followed a railscast episode and got datatables up and running, 
beautifully along with the nice jquery-ui as in the front page.

The main issue I''m having though is that I suck at CoffeeScript/JS  ~_~


I''m trying get the datatables to reload every 1 second but I don’t see
any
request coming into my webserver for refreshes and hence, no refreshes on 
the web page itself. 

Here''s my code:

app/assets/javascripts/comments.js.coffee
[code]
jQuery ->
  $(''#comments_id'').dataTable
    sPaginationType: "full_numbers"
    bJQueryUI: true
    bProcessing: true
 
setInterval(''$("#comments_id").dataTable().fnDraw()'',
1000);
[/code]
                

And here is the code that gets generated on the client side:
[code]
(function() {

  jQuery(function() {
    $(''#comments_id'').dataTable({
      sPaginationType: "full_numbers",
      bJQueryUI: true,
      bProcessing: true
    });
    return
setInterval(''$("#comments_id").dataTable().fnDraw()'',
1000);
  });

}).call(this);
[/code]

Help will be appreciated. ^_^

Take a look at the documentation for setInterval():

http://www.w3schools.com/jsref/met_win_setinterval.asp

Looking at the function signature:

setInterval(code,millisec,lang)

code = The function that will be executed.

You have passed a string for this argument. You can''t call a string.

Solution: Give setInterval a function as is expected:

In JavaScript it should look something like:
setInterval(function() {
  $("#comments_id").dataTable().fnDraw();
}, 1000);
