can't select a column

pipo75

I create a dataTable from a json source :

var table = $('#example').dataTable({
"data": source,
"columns": columns,
"columnDefs": defs
});

It is well displayed but when I try to select dynamically a column as i saw in doc ( http://datatables.net/reference/api/column().visible() )

var col1 = table.column("1");

It launchs an error: Uncaught TypeError: undefined is not a functionWord:678 refreshTabWord:502 (anonymous function)jquery-2.1.3.js:3094 jQuery.Callbacks.firejquery-2.1.3.js:3206 jQuery.Callbacks.self.fireWithjquery-2.1.3.js:3412 jQuery.extend.readyjquery-2.1.3.js:3428 completed

Do you have an idea about what happens and how to fix it?

Read the example again. You are not calling the visible() method.

Thaks for answere but I had tried differents ways:

=>table.column("0").visible(false);

=>table.column(0).visible(false);

=>var isVisible = table.column(0).visible() === true ? 'visible' : 'not visible'

=> var data = table.columns([0, 1]).data();

and it does not work as in example

Just for checking if problem was my source I have tried with another javascript source as in example : http://www.datatables.net/examples/data_sources/js_array.html and it fails too

Finally It doesn't work with that because I am using dataTable rather than DataTable
