Question

I think I know the issue with this, but I do not know how to approach it properly so I am hoping someone here has had a similar issue and managed to fix it some how. What I have is a table with a few columns all of which work as far as sorting goes except one. below is a screen capture of that column and its sorting at work.

as you can see it does not sort according to alpha-numeric logic. My assumption is that some of the names have characters in them such as comma’s parentheses, brackets, and so on. So that said, how would I tackle this issue so I can sort this alpha-numericly using the datatables plugin? Idea’s?

****EDIT****

This is the code I am working with, works for everything but this one column..

jQuery.fn.dataTableExt.oSort['num-asc']  = function(a,b) {
    var x = a.replace( /<.*?>/g, "" );
    var y = b.replace( /<.*?>/g, "" );
    x = parseFloat( x );
    y = parseFloat( y );
    return ((x < y) ? -1 : ((x > y) ?  1 : 0));
};

jQuery.fn.dataTableExt.oSort['num-desc'] = function(a,b) {
    var x = a.replace( /<.*?>/g, "" );
    var y = b.replace( /<.*?>/g, "" );
    x = parseFloat( x );
    y = parseFloat( y );
    return ((x < y) ?  1 : ((x > y) ? -1 : 0));
};

$(document).ready(function() {
    $('#ledger').dataTable({
        bAutoWidth: false,
        bJQueryUI : true,
        bProcessing: true,
        bServerSide: false,
        sPaginationType: "full_numbers",
        bStateSave : false,
        bUseRendered: false,
        iDisplayLength: ${entriesValue},
        sDom: mw.superadmin.datatable.relatedListDom,
        aLengthMenu: mw.superadmin.datatable.relatedListLengthMenu,
        aaSorting: [[0,'asc']],
        aoColumns: [
            null,
            { "iDataSort": 2},
            { "bVisible": false, "sType": "num"},
            { "iDataSort": 4, "bSortable": true },
            { "bVisible": false, "sType": "num"}
        ]
    });

Since you’re showing a link, I’m guessing you’re using a custom render function?

If that’s the case, in your column definition set the following:

"bUseRendered": false

That’ll make the table sort on the data, and not the rendered output.
