Hi there
Firstly thanks for the amazing tool. All working great even for a novice - except I'm totally stumped here:
Hopefully the datatables live link shows what's going on.
The console log shows the fnGetPosition is undefined.
Can anyone help fix this example.
I'm trying to read the (hidden) id field a datatable based on the clicked cell.
Any help much appreciated.
Thanks.

    Second FAQ :-).

    Use $().dataTable() (lowercase d) if you want to use the old style API methods (I'd recommend you to use the new style API if possible).

    Thanks for the really quick reply.
    So what is the new style way of looking up the underlying data for the row of a given cell?
    Sorry if I'm asking another FAQ.

    cell().data(). The new API is introduced in the manual and has an overview. Would be interested to know what you think of it.

    Thanks again Allan. So I can do $(this).data() where this is my clicked td and that gives the data for the whole row? Sorry if I'm still confused. A concrete example would be really helpful. Otherwise I'll give it another go when I'm back coding!

    $(this).data()

    No, you can use the cell().data() method. For example: table.row( this ).data().

    If you want it for the whole row, you would use row().data(). For a column use column().data(). Keep in mind that each of the selector methods have their own selector types as well. The documentation for each covers them in detail.

    Fantastic. That gives me the data given the row. But how do I get the row given the cell? What's the new style version of fnGetPosition? Can I do cell().row()? Last question, honest!

    But how do I get the row given the cell?

    table.row( this.parentNode ).data()
    

    where this is a cell.
