div tag not collapsing/expanding using jquery

Question

I've the below html and the div containing class tabHeader is not expanding/collapsing at all.

<div class="tabHeader">
     <li><a href="#" id='onejltab' class="tablinks">1JL(Mobile)</a></li>
      <div class="insideTabHeader">
          <li><a href="/onejl/1" class="tablinks" style="text-align:center">Network</a></li>
          <li><a href="/onejl/2" class="tablinks" style="text-align:center">Application</a></li>
          <li><a href="/onejl/3" class="tablinks" style="text-align:center">Integration</a></li>
          <li><a href="/onejl/4" class="tablinks" style="text-align:center">Infrastructure</a></li>
      </div>
</div>

Have written the below jquery to collapse/expand the div tabHeader

$("#tabHeader").click(function () {

    $tabHeader = $(this);
    $insideTabHeader = $tabHeader.next();
    $insideTabHeader.slideToggle(500, function () {
    });

});

I'm not sure why the above jquery isn't working. Any help/solution would be of great help.

Thanks in advance.

Answer 1

1- Use the anchor id or class instead of the div

2- use $tabHeader.closest('li').next(); instead of $tabHeader.next();

$("#onejltab").click(function () {

    $tabHeader = $(this);
    $insideTabHeader = $tabHeader.closest('li').next();
    $insideTabHeader.slideToggle(500, function () {
    });

});

Demo

 $("#onejltab").click(function () { $tabHeader = $(this); $insideTabHeader = $tabHeader.closest('li').next(); $insideTabHeader.slideToggle(500, function () { }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="tabHeader"> <li><a href="#" id='onejltab' class="tablinks">1JL(Mobile)</a></li> <div class="insideTabHeader"> <li><a href="/onejl/1" class="tablinks" style="text-align:center">Network</a></li> <li><a href="/onejl/2" class="tablinks" style="text-align:center">Application</a></li> <li><a href="/onejl/3" class="tablinks" style="text-align:center">Integration</a></li> <li><a href="/onejl/4" class="tablinks" style="text-align:center">Infrastructure</a></li> </div> </div>
