i trying run condition find td n/a , remove contents on first td of table. precisely, remove text displayed between brackets in first td i.e. "(id-25)" if of text in table "n/a". how can accomplish that? support appreciated!!!

try:

$('td:contains("n/a")').each(function () {     if ($(this).children().length == 0) {         $(this).closest('table').find('td').first().text($(this).closest('table').find('td').first().text().replace(/\(.*\)/ig, '()'));     } });
