javascript - Unable to remove a class from an element once it has been added -

-

problem recreatable @ following url :

http://streeten-new.streeten.co.uk/

  • click hamburger open navigation
  • click "services"
  • click "< services" inside submenu try , go back

for reason, removeclass not removing 'submenuactive" class. know sure targeting right element, because adding test class works without issue.

i have tried using pure javascript instead of jquery this, have tried changing css directly jquery, rather adding/removing class - in cases i'm unable undo changes make element when submenu first opens.

it's frustrating because opening dev tools , highlighting 

<ul class="submenuactive">

then unticking 

.submenuactive {     left: 0!important; }

rule hides submenu want work, reason cannot working on click.

html code added:

<nav>         <div class="navigation">             <ul >                 <li><a href="#">studio</a></li>                 <li class="parent"><a href="#">projects</a>                     <ul>                         <li><a href="#">portfolio</a></li>                         <li><a href="#">case studies</a></li>                     </ul>                 </li>                 <li class="parent"><a href="#">services</a>                     <ul>                         <li class="menutitle"><span class="backarrow">&#10094</span> services</li>                         <li><a href="#">branding</a></li>                         <li><a href="#">web design</a></li>                         <li><a href="#">online marketing</a></li>                         <li><a href="#">marketing</a></li>                     </ul>                 </li>                 <li><a href="#">blog</a></li>                 <li><a href="#">contact</a></li>             </ul>              <a id="tel" href="tel:02076313720"><button>call now</button></a>     <!--        <p>for free design consultation</p>-->         </div>     </nav>

javascript code added:

$(".parent").click(function(){         $(this).find("ul").first().addclass("submenuactive");     });      $(".menutitle").click(function(){         $(this).closest("ul").removeclass("submenuactive");         $(this).closest("ul").addclass("test");     });

when click on submenu item, click event bubbles dom , re-triggers click on parent. try suppress with:

$(".menutitle").click(function(e){     e.stoppropagation();     $(this).closest("ul").removeclass("submenuactive");     $(this).closest("ul").addclass("test"); });

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
