    How to associate (reference) a button with a div?

    I'm making a standard hierarchy (or tree) control in which any node with children will have a button to hide/show subnodes. So I'd like to have some way to associate the button with the div that it hides/shows. With code sort of like this:
    Code:
    $(".hideShow").click (function () {
      var $subject = getHideShowSubject (this);
      $subject.toggle();
      toggleHideShowSymbol (this);
    });
    The getHideShowSubject function would need to access an encoding of a pointer from the button to the subject div (in html).

    Is there a conventional way to encode that pointer in HTML? One way to do it would be with HTML5 custom attributes, but what was the convention before HTML5?

    Hi,

    If I understand you correctly, take a look a the code I created and tell me if that's what you meant.

    HTML Code:
    .divs {
      display: none;
      
    }
    
    <div class="item">
        <button>click 2</button>
        <div class="divs">
          <p>Testing 1</p>
          <p>Testing 2</p>
        </div>
      </div>
      
      <div class="item">
        <button>click 2</button>
        <div class="divs">
          <p>Testing 3</p>
          <p>Testing 3</p>
        </div>
      </div>
    Code:
    $('.item > button').each(function() {
      $(this).click(function() {
        $(this).next('.divs').slideToggle();
      });
    });
    Cheers,
    Zitemedia

    Yes, I think that will do it. Using .next with the right selector will do it.

    Thanks.

    });

    This could be a bit more optimized:
    Code:
    $('.item > button').click(function() {
        $(this).next('.divs').slideToggle();
    });

    In my case the subject wasn't the immediately next sibling but this worked:
    Code:
    $control.nextAll(".subnav:first").slideToggle(toggleDuration);
