AngularJS: callback after render (work with DOM after render)
Create a directive that runs your code in the link function. The link function is called after the template is built. See ng-click to get an idea.

Why ng-transclude’s scope is not a child of its directive’s scope – if the directive has an isolated scope?
Why ng-transclude’s scope is not a child of its directive’s scope if the directive has an isolated scope? ng-transclude designed to allow directives to work with arbitrary content, and isolated scopes are designed to allow directives to encapsulate their data. If ng-transclude didn’t preserve scopes like that, any arbitrary content that you’re transcluding would need … Read more
Set width of a span based on width of another element with pure css
It’s a little bit gimmick but it can be done with pure CSS #setter { display: inline-block; } .container { max-width: 200px; position: relative; display: inline-block; padding-bottom: 1.125em; } .wrap { overflow: hidden; text-overflow: ellipsis; white-space: nowrap; position: absolute; left: 0; right: 0; } <div class=”container”> <div id=”setter”> <span>some variable content</span> </div> <div class=”wrap”> <span> … Read more
AngularJS – UI-router – How to configure dynamic views
There is a plunker showing how we can configure the views dynamically. The updated version of the .run() would be like this: app.run([‘$q’, ‘$rootScope’, ‘$state’, ‘$http’, function ($q, $rootScope, $state, $http) { $http.get(“myJson.json”) .success(function(data) { angular.forEach(data, function (value, key) { var state = { “url”: value.url, “parent” : value.parent, “abstract”: value.abstract, “views”: {} }; // … Read more
Why is ngModel.$setViewValue(…) not working from
The reason is that since you’re creating an isolated scope for your contenteditable directive, the ng-model directive on the same element gets that isolated scope as well. Which means that you have two different scopes that aren’t connected to each other, which both have a form.userContent property that changes separately. I guess you could exemplify … Read more
Wait for data in controller before link function is run in AngularJS directive
The easiest solution would be to use ng-if since the element and directive would be rendered only when the ng-if is resolved as true <my-map id=”map-canvas” class=”map-canvas” ng-if=”dataHasLoaded”></my-map> app.controller(‘MyCtrl’, function($scope, service){ $scope.dataHasLoaded = false; service.loadData().then( function (data) { //doSomethingAmazing $scope.dataHasLoaded = true } ) }) or use promises return { restrict: ‘AE’, template: ‘<div></div>’, replace: … Read more
How to test ‘private’ functions in an angular service with Karma and Jasmine
There is no way to test those functions. Their scope is the function that comprises your BracketService factory and they are invisible anyplace else. If you want to test them, then you have to expose them somehow. You can move them into their own service (which seems like overkill) or you can black box test … Read more
$watch is triggered directly after init, why?
On first run both values (newValue and oldValue) are equal, so you may easily escape it by checking for equality: $scope.$watch(“data_copy”, function(newValue, oldValue) { if(newValue === oldValue){ return; } alert(“$watch triggered!”); }); PLUNKER
Angularjs Nested states: 3 level
I solved your problem there : http://codepen.io/yrezgui/pen/mycxB Basically, Ionic is using Angular-UI-Router which has a huge API. In your case, you need to check this link to understand : https://github.com/angular-ui/ui-router/wiki/Multiple-Named-Views#view-names—relative-vs-absolute-names To be short, home1 and home2 states are children of home state, so they can’t have access of menuContent view, because it’s related to eventmenu … Read more
bindToController in unit tests
In Angular 1.3 (see below for 1.4+) Digging into the AngularJS source code I found an undocumented third argument to the $controller service called later (see $controller source). If true, $controller() returns a Function with a property instance on which you can set properties. When you’re ready to instantiate the controller, call the function and … Read more
