Answer 1

You can use,

$(".XXXX tr").has("input.YYYYYY").filter(function() {
  return parseInt($(this).val()) > 36816323;
}).closest("tr");

• Filter through each input.
• Then convert it to number.
• Then return the parent tr after comparing the value.

Answer 2

Use .filter() method:

$(".XXXX tr").filter(function(){
  return +$(this).find('input').val() > 36816323;
}).css('background', 'yellow');

Here .filter() lets you filter the specific tr elements which contains an input with value of more than 36816323 . But remember to parse the input value as number either with leading + or parseInt(val, 10) .
