[jQuery] optimizing

[Bob O]

hello,
Im trying to figure out a better way to do this. it works but its very
sluggish, so i think theyre might be a better way to iterate?

i have an input field = .searchbox

and then i have a YUI datatable that contains about 65 rows.
when i start to type in the search field, it iterates over all the
tr's looks at 2 cell text values and then uses the indexOf method to
determine whether or not to display the <tr>

is there a way that i can iterate once and put those values into cache
or something?

here is my code.

$(document).ready(function () {
  var searchbox = $('.member_search_input');
  var member_row = $('#members_data_table_wrap table tbody tr');
  searchbox.click(function() {
    $(this).val('');
  });
   searchbox.bind('change keyup', function() {
      member_row.each(function() {
        var number = $(this).find('.yui-dt1-col-PhoneNumber div
a').text();
        var name = $(this).find('.yui-dt1-col-Name div').text();
        var search_check_value = (name + number);
        var search_value = searchbox.val();
         if (search_check_value.indexOf(search_value) > -1) {
           $(this).show();
          } else {
          $(this).hide();
        }
      });
    });
});
