thanks :) idan

simplest solution existing code add line:

        $('.tobutton').click(function(){$(this).remove(); });

just after $("#destinationschosen").html(...) block.

i don't recommend putting script in tag because it's not habit, since doesn't separate concerns. short answer has problems too, since getting .tobuttons each time , setting listener again.

the better way this, create tobutton dom node, , append parent div. way, can put listener on node itself.

$(function() {     $("#destinations").autocomplete({         select: function (event, ui) {             $("#destinationschosen").append(function(i, origtext){                 var selectedcountry = ui.item.value.tostring();                 var currenttext = origtext.tostring();                 if ((currenttext.indexof(selectedcountry) >= 0))                 {                     alert("already exists");                 }                 var destination = document.createelement('span');                 destination.classlist.add('tobutton');                 destination.appendchild( document.createtextnode(selectedcountry));                 destination.addeventlistener('click', function(){ this.remove(); });                 return destination;             })         }     }); })

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.
