c# - Difference between ImmutableArray<T> and ImmutableList<T> -


what difference between immutablearray<t> , immutablelist<t>, , best use each?

i think asking use both. blog otherwise points mentioned here.

use immutable array when:

  • updating data rare or number of elements quite small (<16)
  • you need able iterate on data in performance critical sections
  • you have many instances of immutable collections , can’t afford keeping data in trees

use immutable list when:

  • updating data common or number of elements isn't expected small
  • updating collection more performance critical iterating contents

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; } ...
