1 to NaN of {COUNT} issue

jonnebul

Find on DataTables 1.10.12 version.
When u load datatable with preselected lentgth as "All", and with server side.
Smth like:

> var dt = $('#dt').DataTable({
>                 lengthMenu: [[10, 25, 50, -1], [10, 25, 50, "All"]],
>                 serverSide: true,
>                 searching: false,
>                 ordering: false,
>                 pageLength: -1,
>                 displayStart: 0,
>                 ajax: {
>                     url: "url" 
>                 },
>                 language: {
>                     url: "/scripts/DataTables/dt.language.js"
>                 },
>                 columns: [
>                     { data: "memberNumber" },
>                     { data: "name" }
>                 ]
>             });

in this case - it shows in info like "1 to NaN from 41" for example.
so i haven't found any info about it in discussion.

After that i goes to jquery.dataTables.js source and finde out issue in "fnDisplayEnd": function ();
so i've changed this function to:

"fnDisplayEnd": function ()
        {
            var
                len      = this._iDisplayLength,
                start    = this._iDisplayStart,
                calc     = start + len,
                records  = this.aiDisplay.length,
                features = this.oFeatures,
                paginate = features.bPaginate;
            if (features.bServerSide) {
                var minvalue = Math.min(start + len, this._iRecordsDisplay);
                return paginate === false || len === -1 ?
                    start + records :
                    minvalue ? minvalue : this._iRecordsDisplay;
            }
            else {
                return ! paginate || calc>records || len===-1 ?
                    records :
                    calc;
            }
        },

and now it works nice for me.
So question - is it a datatables issue, or i used wrong properties at start?

Sounds like you haven't fully implemented server-side processing, although without a test case it is impossible to say for sure.

Sorry, I don't think so. Because it works when i changing count from select input, it works fine. Even i change from 10 to All, it shows correct number. And when i set (10,25,50, 35, any other number) in constructor (preselected), like in example - it works fine too.
But when i set -1 (for all) - it shows NaN.

Works okay here: http://live.datatables.net/tahojuta/1/edit .

As I say, I'd need a test case showing the issue, or possibly just the JSON returned by the server from the -1 request. My guess is that the information properties are not correct.

Hmm, okay. It return this:
{"draw":4,"recordsTotal":10,"recordsFiltered":10,"data":[..]}
Can't show data, it consists of private information

allan

That looks okay. Can you modify my example to recreate the issue? As you can see, it should work. I'd really need a test case showing the issue to be able to offer any help.

Sorry. I find out solution and reason of this
I've load parameters from hash by function and they loads in string. So i just needed to parseInt them before datatable initialization.
