Let’s say I have…

<form action="#">
    <fieldset>
        to:
        <input type="text" name="search" value="" id="to" />
        from:
        <input type="text" name="search" value="" id="from" />
    </fieldset>
</form>
<table border="1">
    <tr class="headers">

            </table>
        </td>
    </tr>

Now depending upon what data is typed into the textboxes, I need the table trs/tds to show or hide.

So if I type in 63rd in “to” box, and juniper in the “from” box, I need only those two trs/tds showing in that order and none of the others.

Answer 1

I put together a little demo of this code block, but it works for this specific case:

$(function() {
  $('#to,#from').bind('keyup change', function() {
    var to = $('#to').val().toLowerCase();
    var from = $('#from').val().toLowerCase();
    var $th = $('#theTable').find('th');
    // had to add the classes here to not grab the "td" inside those tables
    var $td = $('#theTable').find('td.bluedata,td.yellowdata');

    if (to.length == 0 || from.length == 0) {
      // shortcut - nothing set, show everything
      $th.add($td).show();
      return;
    }

    $th.add($td).hide();
    $th.each(function(idx) {
      var txt = $(this).text().toLowerCase();
      if ((txt.indexOf(to) != -1) || (txt.indexOf(from) != -1)) {
        // the text had the to or the from in it - so show this tr
        $(this).show();
        // and show its corresponding td
        $td.eq(idx).show();
      }
    });

  });
});
