What is the best way to conceal the second and fourth rows of a table using either css or jquery?

I have a piece of code that is dynamic and I need to hide the second and fourth 'tr' elements of the table with the id HMP_options. How can I accomplish this?

<table id="HMP_options" width="100%" cellspacing="0" cellpadding="0" border="0">
  <tbody>
     <tr>
       <td align="left" colspan="2">
          <table cellspacing="0" cellpadding="0" border="0">
            <input></input>
                 <tbody>
                    <tr><td></td></tr>
                    <tr><td></td></tr>    <!-- this tr i want to hide -->
                    <tr><td></td></tr>
                    <tr><td></td></tr>
                    <tr><td></td></tr>   <!-- this tr i want to hide -->
                 </tbody>
           </table>
        </td>
       </tr>

Answer №1

To achieve the desired effect, I recommend utilizing the following CSS rule:

#HMP_options table tr:nth-child(-2n + 4) {
    display: none;
}

For a live demonstration, you can visit http://jsfiddle.net/ZXjWV/

If you are working with IE9+, incorporating jQuery may assist in implementation.

In this particular instance, the assumption is that only the 2nd and 4th rows need to be hidden. To extend this functionality to include hiding every 2nd row (6th, 8th, etc.), the :nth-child(2n) rule should be used instead.

Answer №2

Give this a shot

.HMP_settings > table td:nth-child(2),
.HMP_config > table td:nth-child(4) { visibility:hidden;}

Answer №3

To hide specific table rows using CSS:

.table_options tr:nth-child(2), .table_options tr:nth-child(4){display: none;}

To hide the same rows using jQuery:

$('.table_options tr:nth-child(2), .table_options tr:nth-child(4)').css('display','none');

Answer №4

Learn how to use the eq method in jQuery. This method allows you to select a specific element within a matched set based on its index, starting from zero.

 $("tr:eq(1),tr:eq(4)").hide();
