Answer 1

Your JS is putting an emphasis on the wrong thing. Find is very slow and best avoided if possible -- and it's very possible here. Just change it to this:

$(document).ready(function () {
    $('.glyphicon').click(function () {
        $(this).toggleClass("glyphicon-chevron-down").toggleClass("glyphicon-chevron-up");
    });
});

Try the FIDDLE ,

I have changed the selectors and events like below

$(document).ready(function () {
    $('.divcontainer').click(function () {
        $(this).find("span:eq(1)")
            .toggleClass('glyphicon-chevron-down')
            .toggleClass("glyphicon-chevron-up");
    });
});

Hope this helps

Use this below jquery code and just change glyphicon name as you wish

 <script> $('.collapse').on('shown.bs.collapse', function(){ $(this).parent().find(".glyphicon-menu-right").removeClass("glyphicon-menu-right").addClass("glyphicon-menu-down"); }).on('hidden.bs.collapse', function(){ $(this).parent().find(".glyphicon-menu-down").removeClass("glyphicon-menu-down").addClass("glyphicon-menu-right"); }); </script>

You need to toggle both classes chevron-up and chevron-down . You can find the correct div using the more general glyphicon class.

I also added id to the div, so you don't need to find it by the down class

See: http://jsfiddle.net/amwLaojj/1/

$(document).ready(function () {
    $('#myglyph').click(function () {
        $(this).parent("div").find(".glyphicon")
            .toggleClass("glyphicon-chevron-up")
            .toggleClass("glyphicon-chevron-down");
   });
});

Update:

Instead of ID, you can use:

$('.glyphicon[data-toggle=collapse]').click(function () {

The following code worked for me. As far as I can tell the bootstrap js events only fire on the "div.collapse" element, ie, the hidden and shown block(s). Even the jquery "click" event on "div.panel-heading" or any child was unresponsive.

<div class="panel-heading" role="tab" id="headingOne">
   <h4 class="panel-title">
   <a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="false" aria-controls="collapseOne">
     Getting Started
   <span class="glyphicon glyphicon-menu-right" aria-hidden="true"></span></a></h4>
</div>
<div id="collapseOne" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne">
<div class="panel-body">
    <a id="choosing">Choosing a topic</a>
    <a id="exploring">Exploring a topic</a>
</div></div>

JQuery

$(document).ready(function () {
    $('div.collapse').on("show.bs.collapse || hide.bs.collapse", function () {
      let glyph = $(this).siblings("div.panel-heading").find('span.glyphicon');
      glyph.hasClass("glyphicon-menu-right") ?   glyph.toggleClass("glyphicon-menu-down") :   glyph.toggleClass("glyphicon-menu-right");
    });
});
