invoke the Info callback

mdusoe

I have a table with rows that contain a checkbox for selection. I have code to get the number of selected rows like this:
[code]
function countSelected(){
if(tbl){
return jQuery('input[name=selected_proposal]:checked', tbl.fnGetNodes()).length;
}
return 0;
}
[/code]

I then init the table like this, using that function to return a modified info string:
[code]
return jQuery('.dataGrid').dataTable({

"fnInfoCallback": function( oSettings, iStart, iEnd, iMax, iTotal, sPre ) {
var count = countSelected();
var str = "";
if(count > 0){
str = ", " + count + " of which are selected."
}

return sPre + str;
},
"bAutoWidth": false,
"bJQueryUI": true,
"bPaginate": true,
"bSort": true,
"bInfo": true,
"sScrollX": "100%",
"sScrollXInner": "150%",
"bFilter": true
})
[/code]

My question is, how do I get the Info to redraw on the check of a box? When the user checks a box, the info string is not updated until they change pages or change filters or something else that causes a Draw. Unfortunately, calling tbl.fnDraw() in the click handler doesn't work, because it always sends them back to page 1.

Thanks in advance for any help you can provide.
Mike.

Try calling fnDraw( false ), which will effectively do a standing draw.

This did not work. The table resets to page 1 on every fnDraw call. I worked around it by not messing with the info string, I made it so that it keeps a total checked count on a button outside the table, but I would still like to make this happen. Any other ideas?

Edit - But thank you for the response :)

Okay - try this plug-in then: http://datatables.net/plug-ins/api#fnStandingRedraw :-)
