AngularJS 1.5+ Components do not support Watchers, what is the work around?

由 牧云@^-^@ 提交于 2019-12-16 20:16:32
问题 I've been upgrading my custom directives to the new component architecture. I've read that components do not support watchers. Is this correct? If so how do you detect changes on an object? For a basic example I have custom component myBox which has a child component game with a binding on the game . If there is a change game within the game component how do I show an alert message within the myBox? I understand there is rxJS method is it possible to do this purely in angular? My JSFiddle

AngularJS global $http state ajax loader

由 这一生的挚爱 提交于 2019-12-14 03:42:52
问题 I have an AngularJS app, and need an ajax loader for every request done by the $http - is there a simple way to do this. My solution now is to set $rootScope.loading = 1 everytime i call a $http, and on the success set $rootScope.loading = 0.. What is the "best practice" for this? My code now looks like: $rootScope.loading = 1; $http({method : "POST", url:url, data: utils.params(data), headers: {'Content-Type': 'application/x-www-form-urlencoded'}}).success(function() { $rootScope.loading = 0

Referencing the element that is calling a controller function Angularjs ( ng-change / ng-blur / ng-* ? )

由 限于喜欢 提交于 2019-12-14 03:02:43
问题 The original question asked about how to determine which element called the controllers blurr function, but I didn't clarify that I was not specifically asking about ng-blur , but ng-* ( ng-change , ng-focus , ng-mouseover , ng-*) in general. So, with that in mind: How do I determine which element input is calling the blurr() and/or check() functions? html <body ng-app="test"> <div ng-controller="Cntrlr as cntrlr"> <form name="meta_test"> <input type="text" name='inpt' ng-model="cntrlr.inpt"

Angularjs scope.$apply in directive's on scroll listener

由 蹲街弑〆低调 提交于 2019-12-13 21:27:06
问题 I am using the following directive to find out if the user has scrolled to the bottom of the page - 150px and set a scope variable which is being listened to and the following page is loaded. It works fine. My concern is that scope.$apply() is being called multiple times. I need to call $apply() for the directive to work but i am not sure if calling it multiple times can cause problems. Any thoughts? Thank you. myMod.directive('scrollDetection', function () { return { restrict: 'AE', link:

Accessing $scope properties from inside a service in AngularJS

由 半世苍凉 提交于 2019-12-13 19:56:24
问题 I am trying to create a constructor function inside an angular service, which I could then use inside of my different angular controllers. The problem is, my object generated from the constructor needs access to one of the properties on my $scope object in order to function correctly. I have the implementation working with the functionality I am after, but it involves passing the $scope object into the constructor function as a parameter. Is there a better way to accomplish this? Are there

Having an Angular $interval running independent of controller

由 限于喜欢 提交于 2019-12-13 19:18:07
问题 I have different pages on may application which have their own controllers. One of them has an $interval function, let's say a timer. Click on a button will start this interval function, which updates itself every second. What i want to have is, i want to be able to go to any other page in my application (calling different controllers), but i want my interval to continue running until i stop it explicitly from the first controller. A rootScope interval so to speak. How can i do it? EDIT:
