make a button disappear

I have a code where it creates a table if it has a record in the database. In this table, in the last column there is a button that when clicking opens a more detailed screen about that table row. I need to make this button appear only on the first two rows of the table, so that no buttons appear on the other lines. I am trying in several ways, but so far I have not achieved any breakthrough. My code is in Codeigniter.

View:

<div data-widget-editbutton="false" id="wid-id-0" class="jarviswidget jarviswidget-color-blueDark jarviswidget-sortable" role="widget">
    <header role="heading">
        <h2><?= $this->lang->line("view_laudo_wg_title"); ?></h2>
    </header>

  • Why so many repeats on Nth-Child? Also you can do it this way: Childrens[number] = 'Nth-Child('number+')'; $('td:'+Childrens+',th:'+Childrens). addClass('Hidden-Md Hidden-Sm Hidden-Xs')

  • @Ivanferrer this code was someone else who did, I’m just fixing it, I don’t know exactly why so many repetitions. I have tried to contact the same, but does not answer me. Since I graduated!

Change your code for this:

  <script type="text/javascript">
  function setClassTable() {
     $("td:nth-child(1),th:nth-child(1)")
            .addClass('hidden-md hidden-sm hidden-xs');

      for (var i=4; i<=7; i++) {
             $("td:nth-child("+i+"),th:nth-child("+i+")")
             .addClass('hidden-md hidden-sm hidden-xs');
      }
         $("tr:nth-child(1) td:nth-last-child(1),tr:nth-child(2) td:nth-last-child(1)")
            .removeClass('hidden-md')
            .removeClass('hidden-sm')
            .removeClass('hidden-xs');
  }
    pageSetUp();
    var iMin;
    var iMax;

    $("#filtrar_data").on('click', function () {
        iMin = $('#dateMin').val();
        iMax = $('#dateMax').val();
        oTable.fnDraw();

  • I put this code that you sent, it didn’t change anything, the button appears in all records yet, and not just in the first two. Thank you!

  • @Ketlin, publish the $this->table->generate() method, the one that builds the table, I need to see how you’re putting it together, or build the table so I understand where you want to hide the first 2 buttons. How many columns and rows have?

  • I put all the code I have, I didn’t make it, I have to fix it just. I don’t understand it right either. All I have related to this table is this. It has 8 columns, and the last one goes this button. No controller no generateTable no part $this->lang->line("con_laudo_acoes_insp"); that’s where the button name is. I hope I’ve been helping. Grateful for the attention

  • I made a change, see if it works now.

  • Also did not work, the screen gets the message that is loading the data and the button also not disappeared.

  • I thought of making an equation(all records - all records + 2 records) however I did not succeed in turning into code.

  • This last column, what is its structure like? You can hide the button inside the for. type: if (i > 2) { 'hidden element'; } and leaves the others visible, in case you can also pass the class I think it is something like table:last-of-type

  • Now I think you’re right

  • Let’s go continue this discussion in chat.

  • opened the discussion in chat. Grata
