incorrect result using fnGetNodes() after a value is searched in searchbox of jquerydataTables1.9.4

Pallavi

I am using jquery.dataTables.js(1.9.4).
I am using checkbox for select all and deselect all,but I wanted checked value of checkbox of all pages to be persisted so I used

[code]
$(xytable.fnGetNodes()).find("input[name='chklist']").length //to get length of checkboxes
and

$(xytable.fnGetNodes()).find("input[name='chklist']:checked").length // to find length of checked checkboxes
[/code]

here xytable -->table id

but when I search a value in search box then the content changes say from 8 results their are only 2 result displayed(which is correct) but the length I get of all the checkboxes by fnGetNodes() remain 8 and not 2(which is incorrect) !!!!

Can you please link to a test case as noted in the forum rules. I'm not sure why that wouldn't work.

hey have provided js fiddle link

http://jsfiddle.net/Pallavik/pJG9f/45/

here length remains 6,even if 1 result(checkbox) is displayed when 'g' is searched in Search Box and 'Click here to check length' is clicked.

js fiddle I created is just to show the problem

I have used definitions for dataTable as

[code]
oTable=$("#tablename").dataTable({
"bProcessing":true ,
"sProcessing":"Processing",
"iDisplayLength": 5,
"aoColumnDefs": [
{ 'bSortable': false, 'aTargets': [ 0,4 ]}
] ,
"bPaginate": true,
"sPaginationType": "input",
"bInfo": false,
"bAutoWidth": false,


});
[/code]

is anything in definition causing trouble?

Ah I understand now - so you want only the nodes which are currently visible to be selected? In which case, don't bother with fnGetNodes - just use `$('input[name='checklist']')` . Or do you want something more complicated than that? What about paging?

thanks for ur prompt response

I don't want only currently visible ones as I have used pagination .

In short I want total length of the checkboxes (including in 2nd,3rd etc pages)after search is applied and total length of checkboxes which are checked(after search is applied).

allan

In which case use the $ API method - http://datatables.net/docs/DataTables/1.9.4/#$ - specifically the `filter` option - set it to `applied` .

hey thanks for the solution!!!!!works smoothly

used

[code]
oTable._("input[name='chklist']", {"filter":"applied"}); //to find all my checkboxes
//and
oTable._("input[name='chklist']:checked", {"filter":"applied"}); //to find all my checked checkboxes
[/code]
