javascript - do events registered with angular.element get removed by $destroy? -


i've read angular listeners ($scope.$on) automatically removed $destroy. , i've read outside event handlers jquery ($(document).on) need manually removed.

does know angular.element falls paradigm?

a team member wrote angular.element(document).on('event', () => );. need manually remove event in $ondestroy?

angular.element (jqlite) is tiny, api-compatible subset of jquery allows angularjs manipulate dom in cross-browser compatible way. jqlite implements commonly needed functionality goal of having small footprint.

directive link functions use attach event listeners elements other directive's own element need unregister listeners when directives element destroyed.

function postlink(scope, elem, attrs) {      $document.on('event', documenteventhandler);      scope.$on("$destroy", function() {         $document.off('event', documenteventhandler);     });      function documenteventhandler(event) {         console.log(event.target);         //other code here     }); }

to facilitate unit testing, inject angularjs $document service instead of using angular.element(document).

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
