Twitter bootstrap 3.0 cambio de icono en el colapso

Los eventos collapse se manejan de manera diferente en Bootstrap 3. Ahora sería algo como:

$('#collapseDiv').on('shown.bs.collapse', function () {
   $(".glyphicon").removeClass("glyphicon-folder-close").addClass("glyphicon-folder-open");
});

$('#collapseDiv').on('hidden.bs.collapse', function () {
   $(".glyphicon").removeClass("glyphicon-folder-open").addClass("glyphicon-folder-close");
});

Para el botón de signo más y menos de colapso de bootstrap.

HTML

<div>
  <a data-toggle="collapse" href="#other">
    <h3>Others<span class="pull-right glyphicon glyphicon-plus"></span></h3>
  </a>
  <div id="other" class="collapse">
    <h1>Others are</h1>
  </div>
</div>

Javascript

$(document).ready(function () {
     $('.collapse')
         .on('shown.bs.collapse', function() {
             $(this)
                 .parent()
                 .find(".glyphicon-plus")
                 .removeClass("glyphicon-plus")
                 .addClass("glyphicon-minus");
             })
         .on('hidden.bs.collapse', function() {
             $(this)
                 .parent()
                 .find(".glyphicon-minus")
                 .removeClass("glyphicon-minus")
                 .addClass("glyphicon-plus");
             });
         });

Esta es una solución basada en CSS que se basa en el bootstrap predeterminado.implementación de js collapse. No se requiere marcado HTML adicional (siéntase libre de reemplazar Font-Awesome con glyphicons, por supuesto).

<style>
    .panel-title > a:before {
        font-family: FontAwesome;
        content: "\f07c";
        padding-right: 5px;
    }
    .panel-title > a.collapsed:before {
        content: "\f07b";
    }
</style>

DEMO (Bootstrap 3.3.7):

DEMO (Bootstrap 4.0 / Fuente Impresionante 5 CSS):

También podría usar una clase como destino en lugar de un id.

 <a data-toggle="collapse" href=".details">
     <div class="details collapse in">Show details</div> 
     <div class="details collapse">Hide details</div> 
 </a>
 <div class="details collapse">
 ...
 </div>

Usando solo CSS, el icono de colapso de bootstrap se puede cambiar con sus iconos predefinidos:

a[aria-expanded=true] .glyphicon-plus {
    display: none;
}
a[aria-expanded=false] .glyphicon-minus {
    display: none;
}
.pointer{
  cursor:pointer;
}

<a data-toggle="collapse" class="pointer" aria-expanded="false" data-target="#testCollpase" aria-controls="#testCollpase" >
  <span class="pull-left title-sidebar">Filter By Price</span>
  <span class="pull-right"><i class="glyphicon glyphicon-plus"></i></span>
  <span class="pull-right"><i class="glyphicon glyphicon-minus"></i></span>
  <div class="clearfix"></div>
</a>
<div id="testCollpase" class="collapse">
  <ul>
    <li><a href="#">500$</a></li>
    <li><a href="#">1000$</a></li>
  </ul>
</div>

En su HTML agregue aria-expanded="false" y agregue dos iconos lo que necesita establecer en su barra de colapso. Como,

<a data-toggle="collapse" class="pointer" aria-expanded="false" data-target="#testCollpase" aria-controls="#testCollpase" >
  <span class="pull-left title-sidebar">Filter By Price</span>
  <span class="pull-right"><i class="glyphicon glyphicon-plus"></i></span>
  <span class="pull-right"><i class="glyphicon glyphicon-minus"></i></span>
</a>

Y controlarlo desde css. Cuando contraiga la barra expand then

a[aria-expanded=true] .glyphicon-plus {
    display: none;
}

De lo Contrario será

a[aria-expanded=false] .glyphicon-minus {
    display: none;
}

Ejecute el fragmento y creo que solo necesita esto...

Los eventos de colapso se manejan como:

$('#collapse').on('shown.bs.collapse', function () {
   $(".glyphicon")
      .removeClass("glyphicon-folder-close")
      .addClass("glyphicon-folder-open");
 });

 $('#collapse').on('hidden.bs.collapse', function () {
    $(".glyphicon")
       .removeClass("glyphicon-folder-open")
       .addClass("glyphicon-folder-close");
 });

Aquí está mi solución:

$('.navbar-toggle').on('click', function() {
    $(this).toggleClass('mobile-close');
})

Ocultar las barras de iconos predeterminadas:

.mobile-close span {
  display: none !important;
}

Entonces puedes usar el estilo mobile-close como:

.navbar-toggle.mobile-close {    
  cursor: pointer;
  width: 42px;
  height: 32px;
  line-height: 40px;
}
.navbar-toggle.mobile-close:before {
  content: "×";
  font-size: 40px;
  color: #231f20;
 }

Este funciona bien para el colapso de bootstrap:

<script>
    $(document).ready(function () {
        $('#collapseExample').on('hidden.bs.collapse', function () {
            $("#btnDown").removeClass("glyphicon-chevron-up").addClass("glyphicon-chevron-down");
            })
        $('#collapseExample').on('shown.bs.collapse', function () {
            $("#btnDown").removeClass("glyphicon-chevron-down").addClass("glyphicon-chevron-up");
            })
        });
</script>

Este es el código HTML que uso:

<div class="collapse" id="collapseExample">
     <div class="well">
     ...
     </div>
</div>
<button class="btn btn-default" type="button" data-toggle="collapse" data-         target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
     <span id="btnDown" class="glyphicon glyphicon-chevron-down"></span>
     Settings
</button>
