javascript - Angular Select Dropdown with an option to let the user add a custom option -

-
i have html select dropdown in form asks user pick question out of pre-selected security questions. (such "what's favorite city", "what's color of car" etc.) how can add option list such "write own" , when user selects it, new input box shown user write his/her own question. one strategy can think of create input element ng-show hide/show based on value of select. there better way it? your best bet write custom directive simulate select box (likely using styled radio buttons), add option in there input. i've done similar several projects , thought isn't particularly difficult, there lot consider (including accessibility , keyboard controls). or can find 1 of many open-source directives online. while might not you're looking ui-select might option.

multithreading - python socketserver: how to shutdown server with open client connection? -

i have been looking time solution terminate socketserver.streamrequesthandler spawned separate thread class threadingmixin when main tread terminates. problem socketserver thread, although being daemonic, not terminate long there open client connection, when calling shutdown() method @ program shutdown. therefore, main tread did not terminate. none of suggestions in how stop basehttpserver.serve_forever() in basehttprequesthandler subclass? or similar posts worked me. i have found solution: class threadingmixin has property daemonic_threads, default true: class threadingmixin: """mix-in class handle each request in new thread.""" # decides how threads act upon termination of # main process daemon_threads = false in subclass, which, of course, overrides method handle(), defines override in init daemon_threads = true now client requests daemonic , when main thread terminates, terminate. nice ! helps similar problem.

i want container store unique std::weak_ptrs. std:set requires operator<, presumably because stores items in tree. worry if implement operator< in obvious way (destroyed ptr = null ptr < valid ptr) result can mutate after items added container, may break it. is in fact safe? if not, suggestions container? thanks you cannot use weak_ptr s keys unless use owner based comparison (against value based one, not defined weak_ptr , trying use operator< results in error). problem can expire , ordering of containers (a set map ) wouldn't consistent anymore. as correctly pointed out kerrek sb (forgive me, mobile app not let me correctly link users) , can read link in comments, can rely on std::owner_less starting c++11. a valid approach use set defined follows: std::set<std::weak_ptr<c>, std::owner_less<std::weak_ptr<c>>> note owner_less can less verbose, deduces type automatically. keep in mind approach not keep invoking exp...

c++ - Why don't compilers make unsigned vs signed comparison safe? -

this question has answer here: would break language or existing code if we'd add safe signed/unsigned compares c/c++? 6 answers as know, code generate warning: for (int = 0; < v.size(); ++i) the solution auto = 0u; , decltype(v.size()) or std::vector<int>::size_type pretend we're forced have both signed , unsigned value. compiler automatically cast int unsigned int (the actual type doesn't matter). using explicit cast, static_cast<unsigned int>(i) makes warning go away, bad because did same thing compiler did , silenced important warning! the better solution is: if ((i < 0) || (static_cast<unsigned int>(i) < v.size())) understandably, c "closer metal" , consequence more unsafe. in c++, there's no excuse this. c++ , c diverge (as have been doing many years), hundreds of improvements c++ have increased...

-
i'm tring es6 syntax in react, , write components like: export default class loginform extends react.component { getinitialstate() { return { name: '', password: '' }; }; } but browser throws me waring about: warning: getinitialstate defined on loginform, plain javascript class. supported classes created using react.createclass. did mean define state property instead? i can handle traditional syntax var loginform = react.createclass what's correct es6 syntax? another little thing, think in traditional syntax react.createclass object, functions in separated comma, extends class require semicolon, don't understand well. you don't need semicolons or commas between es6 class method declarations. for es6 classes, getinitialstate has been deprecated in favor of declaring initial state object in constructor: export default class loginform extends react.component { constructor(p...

sql - is this functional dependency derivation correct? -
