javascript - last child click doesnt change -


when select box 2, i'd border become black.
click should go yellow.

the first click goes right second click stays black. can fix adding class, don't want to.

how else can this?

this code:

<div class="aa">     <div class="bb">1</div>     <div class="cc"></div> </div> <div class="aa">     <div class="bb">2</div>     <div class="cc"></div> </div> 
$('.bb:last').addclass('yellow');  $('.bb').click(function () {     $(this).next('.cc').fadetoggle();      if (!$('.cc:last').is(':hidden')) {         $('.bb:last').addclass('black');     } else {         $('.bb:last').removeclass('black');         $('.bb:last').addclass('yellow');     } }); 
.bb {     background:red;     width:90px;     height:30px }  .cc {     background:blue;     width:90px;     height:30px;     display:none; }  .yellow {     border:3px solid yellow; } .black {     border:3px solid black; }

you need remove class if has it. 

$('.bb:last').addclass('yellow');  $('.bb').click(function () {     $(this).next('.cc').fadetoggle();     if (!$('.cc:last').is(':hidden')) {         if ($('.bb:last').hasclass('black')) {             $('.bb:last').removeclass('black');         } else {             $('.bb:last').addclass('black');         }     } else {         $('.bb:last').addclass('yellow');     } });
