Custom attribute jquery Datatables

Question

I need create a custom attribute for my datatables instance, and I need keep this value, ex:

When I create an instance:

$('#table').dataTable({
    //common attributes
    ajax: 'url.json',
    columns: [...],
    //custom attribute
    hasSomeValueHere: 'helloword'
});

and I would like to keep it on settings of datatable, so if I check it will be there:

$('#table').dataTable({
    //common attributes
    ...
    fnDrawCallback: function(oSettings){
        alert(oSettings.hasSomeValueHere); //helloword
    }
});

There any way to extends datatable this way? Thanks

Are you using datatables with client side data or do you need to send parameters to the server? — Rick Schmidt

Hmmm, no I don't need to send this params to the server, because I've already keep some values in localstorage as sortColumn, searchValue, page, pagesize... But, now I need keep a custom attribute. — Giolvani

You dont need to extend dataTables for that. oSettings has an object, oInit, that holds the entire initialisation object, i.e the dataTables options. Example :

$('#example').dataTable({
    hasSomeValueHere: 'helloworld',
    fnDrawCallback: function(oSettings){
        alert(oSettings.oInit.hasSomeValueHere); //helloworld
    }
});

This works in 1.10.x as well, using DataTable()

$('#example').DataTable({
    hasSomeValueHere: 'helloworld',
    drawCallback: function(settings){
        alert(settings.oInit.hasSomeValueHere); //helloworld
    }
});
