Get show/hidden column name

Misc

Hi, first i want to thanks you for the great work you did on Datatable.
I'm quite new with this plug-in and I have a little problem with ColVis.

I can retrieve the data using [code]oTable._('tr', {"filter": "applied"});[/code] but but is there any way to get the column name visible in the th elements?

Currently no - there is not pre-built API for this. You would need to access the fnSettings().aoColumns[].sName parameter for the columns. This could readily be wrapped up into a plug-in API method: http://datatables.net/development/api

Thanks you for your quick answer I will try this =).

I try some of the code I found on the forums but it seems it didn't work with me (I've probably forgot a few things -_-).
Here the code i've try with the html example given in the download part.
[code]
$(document).ready(function() {
var oTable = $('#example').dataTable({
"sDom": 'C<"clear">lfrtip',
"aoColumns": [
{ "sName": "engine" },
{ "sName": "browser" },
{ "sName": "platform" },
{ "sName": "version" },
{ "sName": "grade" }
]
} );
ColumnsShown = $('#example').getColumnsShown(this);
alert(ColumsShown);
} );
$.fn.getColumnsShown = function(dTable){
var vCols = [];
$.each(dTable.fnSettings().aoColumns, function(c){
if(dTable.fnSettings().aoColumns[c].bVisible === true){
vCols = vCols.concat(dTable.fnSettings().aoColumns[c].sName);
}
});
return vCols;
};
[/code]

That basically looks okay to me - what happens when you run it? I think you want to pass in "oTable" rather than "this" into getColumnsShown btw.

OK, find it ...
[code]ColumnsShown = $('#example').getColumnsShown(oTable);
alert(ColumnsShown);[/code]
forgot the n ...
Thanks for your answers it' works =).
Now I'm looking on listeners for filtering and hiding columns (Colvis); I want to recover those data when any columns are filtered or hidden, any tips?
