Question

I’m trying to highlight rows in a table using jQuery, but I’m wondering if it’s possible to use a variable for the row I want highlighted. This is the code I have now, which is not working.

  var rowNumber = 3 //I want to use a loop, but for testing purposes I have it set to 3
  $('tr:eq(rowNumber)').addClass('highlight');

Answer 1

Sure, why not. You may pass a variable in :eq() selector:

$("tr:eq(" + rowNumber + ")").addClass("highlight");

or use eq() method instead:

$("tr").eq(rowNumber).addClass("highlight");
