javascript - Navigation ul li a detect which is clicked and do something -


i've decided build own navigation scratch.

i using jquery if/else handle interaction.

the issue having detecting ul li clicked, , doing based upon result (using $this). can first depth level function correctly, ie first ul li on-click opens first sub-child ul class .c (c = child), not next depth level below that, ie second ul li doesn't open second sub-child ul class .sc (sc = sub child).

here fiddle.

here live example:

!function(n){  		$('ul li + ul').prev('a').append('<span class=ai></span>');  		$('ul li a').on('click', function(n) {  		  if($('.c').css('display') == 'none') {  			  $this = $(this);  			  $(".c").slidetoggle();  			  $this.find('span.ai').toggleclass('st');  			  n.preventdefault();  		  } else if($(this).is('ul li.p a')) {  			  $this = $(this);  			  $(".c").slidetoggle();  			  $this.find('span.ai').toggleclass('st');  			  n.preventdefault();  		  } else if ($(this).is('ul li.sp a')) {  			  $this = $(this);  			  $(".sc").slidetoggle();  			  $this.find('span.ai').toggleclass('st');  			  n.preventdefault();  		  }  		});  }(jquery);
ul {    list-style: none;    display: -webkit-box;    display: -moz-box;    display: -ms-flexbox;    display: -webkit-flex;    display: flex;  }  ul li {    line-height: 50px;    height: 50px;    -moz-transition: 1s ease;    -webkit-transition: 1s ease;    -o-transition: 1s ease;    transition: 1s ease;    background: #c8c8c8;    text-align: center;    -webkit-box-flex: 1;    -moz-box-flex: 1;    -webkit-flex: 1;    -ms-flex: 1;    flex: 1;    align-items: center;  }  ul li {    display: block;  }  ul li ul {    display: none;  }  ul li ul li {    text-align: left;    text-indent: 10px;  }  ul li ul li ul {    display: none;  }  ul span {    width: 0;    height: 0;    margin-left: 10px;    display: inline-block;    border-top: 6px solid transparent;    border-bottom: 6px solid transparent;    border-left: 6px solid #000;    -moz-transition: -moz-transform 0.3s;    -webkit-transition: -webkit-transform 0.3s;    -o-transition: -o-transform 0.3s;    transition: transform 0.3s;    vertical-align: middle;  }  ul span.st {    -moz-transform: rotate(90deg);    -o-transform: rotate(90deg);    -webkit-transform: rotate(90deg);    transform: rotate(90deg);  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div x-n>  		  <ul>  			<li><a href="#" title="home">home</a></li>  			<li class=p><a href="#" title="about us">about us</a>  				<ul class=c>   					<li class=sp><a href="#" title="history">history</a>  						<ul class=sc>  							<li>beginnings</li>  						</ul>  					</li>  					<li><a href="#" title="our team">our team</a>  					<li><a href="#" title="our mission statement">our mission statement</a>  				</ul>  			</li>  			<li><a href="#" title="clients">clients</a></li>  			<li><a href="#" title="work">work</a></li>  			<li><a href="#" title="contact">contact</a></li>  		  </ul>          </div>

things have tried:

  • anonymous function
  • using :not operator in reference $(this) ie, else if($(this).is('ul li.p a:not(ul li.sp a)'))
  • using integer variable detect how many clicks based on criteria , doing

there's simple solution here , i'm not seeing it. ideas?

seems overcomplicated.

something should work

  $('ul li a').on('click', function(e) {                     var $link=$(this), $submenu = $link.siblings('ul');         if($submenu.length){             e.preventdefault();             $link.find('span.ai').toggleclass('st');             $submenu.slidetoggle()         }             });

i'm not 100% sure expected behavior is
