Removing only the closest thead on table filtering

186 views Asked by At

I am attempting to remove only the closest thead when filtering with this line of JS "$("tr:not(.wb-hide)").closest("thead").addClass("wb-hide");". The issue is both thead's are getting removed. Any thoughts or solutions would be greatly appreciated.

Try this fiddle:

$('thead').addClass("wb-hide");
$("tbody>tr:not(.wb-hide)").parents('table').find('thead').removeClass("wb-hide");

in place of

$("tr:not(.wb-hide)").closest("thead").addClass("wb-hide");
