Rails 3.1 CoffeeScript not working

I convert my old JS files into CoffeeScript, In my public controller I
used this functions

$('#events a').lightBox()

$(document).ready ->

  $("#slider").easySlider
    auto: true,
    continuous: true

they load inside application.js like this

(function() {
  $('#events a').lightBox();
  $(document).ready(function() {
    $("#slider").easySlider({
      auto: true,
      continuous: true
    });
});

but it doesnt seems to work, also tried with an alert "hello" and doesnt
work neither, what i'm doing wrong?

Try

$ ->

$(’#events a’).lightBox()

$("#slider").easySlider

  auto: true
  continuous: true

There is an online js to coffeescript converter out there, I just can’t find the link right now too.

Hope this helps :slight_smile:

});

Isn't .call(this) missing at the end? The function is not called at
all, no wonder it doesnt work.

I found the problem, a jquery plugin isnt loading well.

Uncaught TypeError: undefined is not a function

but it was working after rails 3.1, is beeing loaded at the end of the
file so it should be ok

(bubblepopup plugin)

the problem is that coffee creates this in a private scope, so any method from inside that scope can't be called..

try

window.testFunction: (param) ->
  alert param

and

testFunction2: (param) ->
  alert param

and check 'compiled' code of both

the function with "window" prefix will be available globally, instead of the other one

there's a big difference between (after 'compiling')

(function () {
  var testFunction2 = function(param) {
    alert(param);
   }
}();

and
var testFunction = function(param)
  alert(param);
}

as for the first case, there's no publicly exposed part of the first testFunction2 function.
