how find out elements on page listening jquery event?

i'm trying write script move tiles on site: http://threesjs.com/. tried send keypress event arrow keys, didn't work: 

$('*').trigger(jquery.event('keypress',{which:$.ui.keycode.up}));

and:

var e=jquery.event('keypress'); e.which=39; $('*').trigger(e);

the tiles move when arrow keys on keyboard pressed, , should sending keypress elements, board doesn't react when executing in console. think best way trigger board movement find out element listening key down event.

a better way manually triggering jquery events pull out handlers callable functions. this:

function handlearrow(direction){   // code here }  // handlers keypress $(document).on('keypress',function(){   var direction = /*find out key*/;   handlearrow(direction); });  // manual trigger handlearrow('left');

(insert standard globals , namespacing warning here) :p

C# random value from dictionary and tuple -

i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
