Button icon failing to respond to click event

I am facing an issue with a button that includes both text and a down-arrow icon. When I click on the text part of the button, a dropdown appears as expected, and I have incorporated jQuery to update the text and rotate the arrow icon - all working fine. However, when I click on the icon part of the button, the text changes and the icon flips but the dropdown does not show up.

Should I change it to an anchor link and adjust the clickable area, or is there a simpler solution available?

HTML

<button type="button" class="btn btn-info button-drop text-nowrap" data-toggle="collapse" data-target="#ph-detail" aria-expanded="false" aria-controls="ph-detail">See More 
<i class="bi bi-arrow-down"></i>
</button>

<div class="collapse" id="ph-detail">
<p>Expandable content</p>
</div>

JQuery

$('.button-drop').click(function() {
  $(this).toggleClass( "active" );
  if ($(this).hasClass("active")) {
    $(this).html('See Less <i class="bi bi-arrow-up">');
  } else {
    $(this).html('See More <i class="bi bi-arrow-down">');
  }
});

It seems that both code snippets are functioning correctly for me. It is possible that you may have forgotten to include the CDNJS file for jQuery.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js" integrity="sha512-bLT0Qm9VnAYZDflyKcBaQ2gg0hSYNQrJ8RilYldYQ1FxQYoCLtUjuuRuZo+fjqhx/qtq/1itJ0C2ejDxltZVFg==" crossorigin="anonymous"></script>

$('.button-drop').click(function() {
  $(".button-drop").toggleClass( "active" );
  if ($(".button-drop").hasClass("active")) {
      $(".button-drop").html('See Less <i class="bi bi-arrow-up">');
    } else {
      $(".button-drop").html('See More <i class="bi bi-arrow-down">');
    }
});

$('.button-drop').click(function() {
  $(this).toggleClass( "active" );
  if ($(this).hasClass("active")) {
      $(this).html('See Less <i class="bi bi-arrow-up">');
    } else {
      $(this).html('See More <i class="bi bi-arrow-down">');
    }
});

Answer №2

After much trial and error, I managed to crack it using the following method:

<button type="button" class="btn btn-info button-drop text-nowrap" data-toggle="collapse" data-target="#ph-detail" aria-expanded="false" aria-controls="ph-detail"><span>Expand </span>
<i class="bi bi-arrow-down"></i>
</button>
$('.button-drop').click(function() {
    $(this).find('i').toggleClass('bi bi-arrow-up');
    $(this).find('span').text(function(a, text) {
        return text === "Expand " ? "Collapse " : "Expand ";
    });
});

Recently, I encountered a similar issue where it seemed like the onClick function wasn't working as expected. However, upon closer inspection, I realized that the function was indeed triggering but there was a quick state change due to an event listener I had set up to close my drop-down menu when clicking outside of it.

window.onclick = function (event) {
  if (!event.target.matches(".dropdown button")) {
    var dropdowns = document.getElementsByClassName("dropdown-content");
    for (var i = 0; i < dropdowns.length; i++) {
      var openDropdown = dropdowns[i];
      if (openDropdown.style.display === "block") {
        openDropdown.style.display = "none";
      }
    }
  }
};

This led to a race condition where the style changed from "block" to "none" almost instantly. Even though I was using vanilla JS instead of jQuery, I believe the underlying issue is the same and might be what the original poster was experiencing.
