jQuery - check for empty TDs and if all empty hide the parent TR

Question

I\'d like to check for empty TDs (classes a-h only) and if all are empty, then I\'d like to hide the parent TR. The issues I\'m running into are, my empty TDs contain \" \"

Answer 1

$('tr').each(function(){
  var emptyTdArray=$(this).find('td:not(:.requirementRight,:empty)').filter(function() {     
  return $(this).html()!= " ";  
  });

  if(emptyTdArray.length==0)
  {
     $(this).hide();
  }
});
