javascript - What is best way to refactor these series of if statements? -

-

so have bunch of questions radio buttons, each question having 3 options choose from. have bunch of if statements ( lot of them) determine final answer based on answers each question.

for example: 

question 1 :             a)            b)            c)  question 2 :             d)            e)            f)  question 3 :             g)            h)            i)

and on.

if statements follows : if ( question 1 == || question 2 == f && question 3 == )

if want conditions form of if statements, it'd take space , not best practice.

what best way refactor these if statements?

if every single combination of choices leads unique outcome, you're looking @ n-dimensional matrix. in simpler words, think of every option step in path in array:

$outcomes = array(     'a' => array(         'd' => array(             'g' => 'outcome 1',             'h' => 'outcome 2',             'i' => 'outcome 3'         ),         'e' => array(..),         ..     'b' => array(..),     .. );  echo 'the outcome is: ', $outcomes[$question1][$question2][$question3];

whether best possible way implement questionable, don't know without knowing more logic.

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.
