hello all,

i am trying to get the sum of each column, how should i do that ?

i have used a table on more then 12 pages, and defined at first home page which is included at all pages,
here is code with i want to show the sum of each column

$('#example').dataTable(
{

//"bJQueryUI": true,
"sScrollX": "110%",
"bScrollCollapse": true,
"iDisplayLength": 10,
////// add more show per page list "aLengthMenu": [[25, 50, 100, -1], [25, 50, 100, "All"]];
"sDom": 'rt<"bottom"iflp<"clear">>',
"sPaginationType": "full_numbers"
} )

Thanks

What you can do is something like:

$('#example').dataTable()._('td:nth-child(4)')

That will give you an array of data from the 4th column which you can sum as you would do any other array :-)

Thanks

Here is my code from above running: http://live.datatables.net/odawav/edit . Have a look at the console in your browser and you'll see the data array.

Hi there, did you manage to resolve this, I am looking to do the same, when I looked at Allans example it doesnt appear to show summary in footer?

Thanks

Have you looked at this example: http://datatables.net/release-datatables/examples/advanced_init/footer_callback.html

Hi Allan, many thanks for the reply, I did indeed see that example and several others but not being good with js I am still struggling. Using your excellent example I did manage to sum a single column but cannot fathom out how to sum multiple from dynamic table. I edited your code to simply sum a column [1] as such;

<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$('#example').dataTable( {
"fnFooterCallback": function ( nRow, aaData, iStart, iEnd, aiDisplay ) {
var iTotalCases = 0;
for ( var i=0 ; i<aaData.length ; i++ )
{
iTotalCases += aaData[i][1]*1;
}
						
/* Calculate the market share for browsers on this page */
var iPageCases = 0;
for ( var i=iStart ; i<iEnd ; i++ )
{
iPageCases += aaData[ aiDisplay[i] ][2]*1;
						}
						
/* Modify the footer row to match what we want */
var nCells = nRow.getElementsByTagName('th');
nCells[1].innerHTML = parseInt(iPageCases * 100)/100 +
'';
}
} );
} );
</script>

Also tried this but doesn't output the summary;

 <script type="text/javascript" charset="utf-8">
    $(document).ready(function() {
    $('#example').dataTable();
     console.log( $('#example').dataTable()._('td:nth-child(2)') )
	 } );
	 </script>

Kind Regards
