c++ - how to get the STL list which is stored in a STL array? -


i'm trying making hash table stl array , list . in header file it's defined 

              typedef std::list<bike*> bikeptrlist;

and 2 classes : 

class bikehashtableadt : public std::array< bikeptrlist, 256 > class bikehashtableimp : public bikehashtableadt

i'd store " bike* " in list , , store lists in array. in cpp file call function

void bikehashtableimp::addbikeptr(bike* ptr) {     int hashint = hashfun(ubptr->license); // integer returned hash function       bikeptrlist &tmp=(*this)[hashint];  // "this" means class bikehashtableimp     std::list<bike*> tmp.push_back(ptr);     (*this)[hashint]=tmp;              }

there run-time error , every time function called , new bike* ptr push_back list , prior data stored in list covered. tell me what's wrong code ?

this line:

std::list<bike*> tmp.push_back(ptr);

is wierd. std::list doesn't belong there. did mean write

tmp.push_back(ptr);

?

and line 

(*this)[hashint]=tmp;

also appears unneeded. tmp same (*this)[hashint].

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
