angularjs - angular.js run code ONLY if window is in focus -


i have setinterval function runs every 5 seconds. want code inside function run if window infocus. i've tried doesnt seem work.

$scope.myfunction = function() {   var isonfocus = true;      window.onblur = function() {       isonfocus = false;     }      window.onfocus = function() {       isonfocus = true;     }    if (isonfocus) {        console.log("focused!");   } }  setinterval(function() {   $scope.myfunction(); }, 5000);

i think looking angular's $window wrapper , defining isonfocus outside function lot, too.

app.controller('ctrl', function($scope, $window) {   var hasfocus;    $scope.myfunction = function() {     $window.onblur = function() {         console.log('>onblur');       hasfocus = false;       };        $window.onfocus = function() {         console.log('>onfocus');       hasfocus = true;       };      console.log(hasfocus ? 'focused' : 'not focused');   };    setinterval(function() { // or $interval     $scope.myfunction();   }, 5000); });
