javascript - Angular JS prevent controller from running on hidden element -


i have codes 

.state('foostate', {     url: '/foo',     templateurl: 'path/to/bar.html',     controller:'parentcontroller' })  // bar.html <div class="sample">     <div ng-show="bazinga" ng-controller="child1controller">         <!-- cool stuff -->     </div>     <div ng-show="!bazinga" ng-controller="child2controller">         <!-- cool stuff -->     </div> </div>

is normal when first div controller child1controller shown, controller child2controller run? how prevent controller running if hidden via ng-show="false"? need parentcontroller , child1controller controllers running when first div visible. same when 2nd div visible, parentcontroller , child1controller controllers should one's running.

if i'm not mistaken, using ng-if rather ng-show should solve issue. difference being ng-if not render element dom when evaluates false.

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; } ...
