angularjs - Multiple usages of same controller in angular -


problem angular. on website have comments. each comment shares same 'ng-controller="commentctrl"' directive. when have 300 comments on web site, there 300 commentctrl instances. in html of controller using ng-disabled="author_provided()" on button. when changing author input text field, 300 comments invoking author_provided() ( because function depends on on author ng-model). causes performance issues. want author_provided() function invoked in controller changing author. how achieve ?

the author_provided function evaluated each comment on every $digest cycle. if must circumvent behavior, suggest adding author provided boolean property of comment object. template code can read: ng-disabled=comment.author_provided (no function call) , angular evaluate result without calling controller function.

the function called every comment because templating engine can't know result of ng-disabled each comment without evaluating controller function call.

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; } &l
