jQuery comes with a hover() mouse event to allow attach two event handlers to the matched elements, executed when the mouse enters and leaves the matched elements.

$("#id").hover(A, B);
  1. A – function to call when the mouse enters the matched element.
  2. B – function to call when the mouse leaves the matched element.

This is a best function to highlight a table row record. See the jQuery snippet code :

$("tr").not(':first').hover(
  function () {
    $(this).css("background","yellow");
  }, 
  function () {
    $(this).css("background","");
  }
);

It will highlight the table row record on hover, with color of yellow. The “.not(‘:first’)” is common implementation to avoid highlight the header row record.
