[英]which is best to use $rootScope.$emit or $$rootScope.$broadcast for angularjs loader indicator in angularjs
$rootScope.$emit flows up to $rootScope and $rootScope.$broadcast flows down the scope to $rootScope and all $scope's in angularjs. $ rootScope。$ emit上升到$ rootScope和$ rootScope。$ broadcast下降到$ rootScope和所有$ scope在angularjs中。 I am still confused of what exactly to use for angularjs loader indicator . 我仍然对为angularjs loader指标确切使用什么感到困惑。
$rootScope.$emit
only lets other $rootScope
listeners catch it. $rootScope.$emit
仅允许其他$rootScope
侦听器捕获它。 This is good when you don't want every $scope to get it. 当您不希望每个$ scope获得它时,这很好。
$rootScope.$broadcast
is a method that lets pretty much everything hear it. $rootScope.$broadcast
是一种几乎可以让所有人听到的方法。
