Bootstrap 3 collapse change chevron icon on click

Question

I have read all related questions regarding my question and have tried them all to no avail. I can\'t seem to make my code work, even though I \"think\" almost every code I

Answer 1

you can try this.

Here's the HTML Code:

<a data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="false" aria-controls="collapseOne"> Collapsible Group Item #1<span class="glyphicon glyphicon-chevron-up"></span> </a>

Here's the JQuery

$('#accordion').on('shown.bs.collapse hidden.bs.collapse', function (e) {
         $(e.target).prev('.panel-heading').find("span.glyphicon").toggleClass('glyphicon-chevron-up glyphicon-chevron-down',200, "easeOutSine" );
});

Answer 2

Similar to Bojan's answer, I use this solution.
Change HTML code like this:

<span class="chevron_toggleable glyphicon glyphicon-chevron-down"></span>

It's better to use .on event with respect to .click. Also by using class selector it can be used as a site wide solution.

$('.chevron_toggleable').on('click', function() {
    $(this).toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
});

Answer 3

Pure CSS, with even less code + animation.

HTML part:

   <a data-toggle="collapse" href="#collapseExample" 
      aria-expanded="false" aria-controls="collapseExample">
        Open/Close collapse
        <i class="fa fa-chevron-right pull-right"></i>
    </a>

CSS:

a[aria-expanded=true] .fa-chevron-right {
 transition: .3s transform ease-in-out;
 transform: rotate(90deg);
}

Answer 4

I'd like to offer an option along the same lines as another solution posted here, but uses a single div with transforms. This would also help make clean use of transitions to animate the icons as well.

`a[aria-expanded=true] .fa-chevron-right { transform: rotate(0deg); }

a[aria-expanded=false] .fa-chevron-right { transform: rotate(90deg); // or whatever direction you need }`

Answer 6

Try this more elegant solution:

$('#serviceList').click(function(){
    $(this).find('.servicedrop').toggleClass('icon-chevron-down icon-chevron-up');
});
