javascript - Watch not being called on array push -


i have service peerjs contains array of active streams. when setting webrtc stream there callback called when stream becomes available

call.on('stream', function(stream){     activestreams.push(url.createobjecturl(stream));   });

when stream available push onto activestreams array. watch array value in controller this:

//peerrtc service , .getactivestreams returns activestreams array $scope.$watch(peerrtc.getactivestreams, function(activestreams) {   $scope.activestreams = activestreams; }, true);

but reason watch callback doesn't execute when push url(string) value array.

am overlooking something? because activestreams value changing in callback function?

some condition, async call, need call $scope.apply() make work. try call right after push new data array.

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; } ...
