i understand that, given braced initializer, auto deduce type of std::initializer_list , while template type deduction fail: auto var = { 1, 2, 3 }; // type deduced std::initializer_list<int> template<class t> void f(t parameter); f({ 1, 2, 3 }); // doesn't compile; type deduction fails i know specified in c++11 standard: 14.8.2.5/5 bullet 5: [it's non-deduced context if program has] function parameter associated argument initializer list (8.5.4) parameter not have std::initializer_list or reference possibly cv-qualified std::initializer_list type. [ example: template void g(t); g({1,2,3}); // error: no argument deduced t — end example ] what don't know or understand why difference in type deduction behavior exists. specification in c++14 cd same in c++11, presumably standardization committee doesn't view c++11 behavior defect. does know why auto deduces type braced initializer, templates not permitted

i met issue still don't know causes it. i have script in page: $(function(){ var value = "10"; }); but browser says "referenceerror: value not defined". if go browser console , input either 10 or var value = "10"; either of them can return 10. problem script? edit:just rid of "var" can solve problem. it's declared inside closure, means can accessed there. if want variable accessible globally, can remove var : $(function(){ value = "10"; }); value; // "10" this equivalent writing window.value = "10"; .

** have updated question per , comments received. question is: after calling following code: searchbox searchbox = new searchbox(); // searchbox extends jdialog int state = searchbox.showsearchdialog(); // sets visible true , returns state i want let user enter input in searchbox (jdialog). "halt" jframe class when searchbox.showsearchdialog() called (shouldn't already?? not after setvisible(true) called). , once user presses ok in jdialog (searchbox class) "resume" jframe class , call string query = searchbox.getquery(); . i thought sine setvisible(true) called searchbox.showsearchdialog() method should halt not. code runs through from: seachbox = new searchbox(); int state = seachbox.showseachdialog(); string query = searchbox.getquery(); without stopping. query string coming wrong because user never had chance input before code calls method. jframe class: import java.awt.cursor; @suppresswarnings("serial") public class datap
