javascript - ...scrollTop($(this)...) -

-
i have few div s .class class scroll position defined child of parent, need assign scrolltop() $(this) , $(".class").scrolltop($(this).parent().find('.child').scrolltop()); but code doesn't work... $(".class").scrolltop( function(){ $(this).parent().find('.child').scrolltop() } ); doesn't work either. clue? this assuming reading question right. have mulitple "class" elements have own "child" elements. need use each set every element separately. $(".class").each( function(){ var elem = $(this); var childsscrollposition = elem.parent().find('.child').scrolltop(); elem.scrolltop(childsscrollposition); } );

python - setting attribute in current_thread as state holder -

-
i have wsgi application can potentially run in different python web server environments(cherrypy, uwsgi or gunicorn), not greenlet-based. application handles different paths rest apis , user interfaces. during http call of app there need know, context of call, since implementation logic methods share code of api calls , ui calls , bunch of logic separated in many modules should react differently depending on context. simple , straightforward way pass parameter implementation code, e.g. apicall(caller=client_service_id) or usercall(caller=user_id), it's pain propagate parameter possible modules. solution set context in thread object this? def set_context(ctx): threading.current_thread().ctx = ctx def get_context(): return threading.current_thread().ctx so call set_context somewhere in beginning of http call handler can construct context ovject depending on environment data, , use get_context() in part of code must react depending on context. best practices achive th...

How do you send POST parameters to a function in PHP using Fat-Free-Framework? -

-
the documentation on website bit lacking ( http://fatfreeframework.com/routing-engine ). want use shorthand expression of post: $f3->route('post /login','auth::login'); how send params auth->login() function above? this alternative way of writing it, bit longer: $f3->route('post /login', function($f3) { $params = $f3->get('post'); $auth = new auth; $auth->login($params['username'], $params['password']); } ); if mean auth::login should automatically receive post data argument, can't. all f3 route handlers receive following arguments: the framework instance the route tokens (if any) see here example. anyway, if auth->login function you're referring one included in framework , couldn't work in manner since login() function is not route handler . returns true or false . route handler has little bit more that: example, reroute user on success or ...

i'd want plot function: f(x,y)=x^2-2*y, constraint: x+y=1 in graph functions overlap , not seen restricted function f(x,y). appreciate better if x+y-1=0 transparent. mi code in r: x <- seq(-5, 5, length= 10) y <- x fun1<-function(x,y){x^2-2*y} m <- outer(x, y, fun1) m[is.na(m)] <- 1 persp(x, y, m, theta = 30, phi = 30, expand = 0.5, col = "royalblue", ltheta = 120, shade = 0.75, ticktype = "detailed") par(new=true) fun1<-function(x,y){x+y-1} m <- outer(x, y, fun2) m[is.na(m)] <- 1 persp(x, y, m, theta = 30, phi = 30, expand = 0.5, col = "red", ltheta = 120, shade = 0.75, ticktype = "detailed") some overplotting might help. first plot suggested in comments above. de-select segments constraint violated assigning na, i.e. no plotting , overplot heavier color.
