I simply wish to call a function called fnGetNodes() to get an array of all nodes. (source of data-tables functions to calls: http://datatables.net/api)

I have set up as:

# DataTable
  table = $("#restaurantLocations").DataTable()

# Selecting all
  $("#selectAllLocations").click ->
    rows = table.fnGetNodes()

Yet as I refresh and click the button Select All I receive the following error on the line table.fnGetNodes():

enter image description here

It should be very easy, but how can I call functions on datatables in CoffeeScript?

What is `table` after you refresh? Is `table` what you expect it to be inside the callback? Is `table` in scope when you define that callback? Are you saying `$x.DataTable()` or `$x.dataTable()`? – mu is too short Nov 01 '14 at 18:24
I'm using .DataTable(), add seen in the code – Sauron Nov 01 '14 at 19:25
Got it to work with replacing `table.fnGetNodes()` with `$("#restaurantLocations").dataTable().fnGetNodes()` – Sauron Nov 01 '14 at 19:33
So it was just a typo in `table = $("#restaurantLocations").DataTable()` that should have been `table = $("#restaurantLocations").dataTable()` then? – mu is too short Nov 01 '14 at 19:39
No, some functions need .dataTable() and others .DataTable, so I just call an instance of `$("#restaurantLocations").dataTable()` on those other functions – Sauron Nov 01 '14 at 19:52
How can I call `.toggleClass "selected"` on all the none filtered columns? – Sauron Nov 01 '14 at 19:53
No this did not wok, I cant call anything – Sauron Nov 01 '14 at 20:53
Maybe a minimal demo on jsfiddle.net would help. – mu is too short Nov 02 '14 at 02:43
