How to test directives that use templateUrl and controllers?

阅读更多关于 How to test directives that use templateUrl and controllers?

EDIT: after asking the question, i'm now editing this to elaborate on my findings. My app is modularized using directives. I'm writing my directives such that they (1) create their own scope (2) use templateUrl, and (3) do most of the logic and server data fetching in their controller. The question is how to unit test it, using Mocha with Karma. Lior a test is written for each directive. Since the directive uses templateUrl, I used html2js. the html key should be included as a module - that puts the template into the templateCache. Then, I compiled the directive, and run the link function with

AngularJS - what are the major differences in the different ways to declare a service in angular?

阅读更多关于 AngularJS - what are the major differences in the different ways to declare a service in angular?

I am working on an angularJS app and I am trying to stick with the most efficient and widely accepted styles of development in AngularJs. Currently, I am using this way of declaring my services like so: app.factory('MyService', function() { /* ... */ function doSomething(){ console.log('I just did something'); } function iAmNotVisible(){ console.log('I am not accessible from the outside'); } /* ... */ return{ doSomething: doSomething }; }); However, there are numerous examples out there and I am not quite sure which design style to follow. Can someone with extensive knowledge about services

Directives isolated scope not working properly together with nested views? (AngularJS / UI Router)

阅读更多关于 Directives isolated scope not working properly together with nested views? (AngularJS / UI Router)

I'm using ui-router in a AngularJS project where I have a nested view that contains a custom directive. This directive renders an input field (lets say a filter-field) and its value should be in sync with the controller's scope. This works well for this directive, when the view/state not is nested: jsFiddle / not nested / working as expected var myApp = angular.module('myApp', ['ui.router', 'myComponents']) .config(['$stateProvider', function ($stateProvider) { $stateProvider. state('home', { url: '', template: '<my-filter text-filter="theFilter"></my-filter><button ng-click="inspect()"

How to use <head> tag with Angular directive

阅读更多关于 How to use tag with Angular directive

I tried this in my Angular app, but it does not work. So I tried inserting a custom tag( <mytag> ) into the head and made the directive work with this by replacing "head" with "mytag". This however is not really what I intended, because it adds <mytag> to the body instead of the <head> Does anyone know how to make it work with the head-tag? I had the same challenge. Make sure that your angular app is initialized on the html tag. Then this solution works out of the box. However for us this was not an ideal solution. So I modified Zack Boman (tennisgent) https://github.com/tennisgent/angular

问题 So, I've come up with a few solutions to this and I'm still not quite sure what is best. First for reference there is one similar question I could find, though it's a bit old.

I have created a JSFiddle of the issue I am experiencing here: http://jsfiddle.net/9qxFK/4/ I have an input field that I want to only permit lower case letters, numbers, and hyphens (this field will be used in a URL).

Can anybody tell me why this doesn't work? Thanks, Scott Instead of doing that on

阅读更多关于 How to create an angularJs wrapper directive for a ui-bootstrap datepicker?

问题 I am using the ui.bootstrap.datepicker directive to display some date field. However most of the time I need the same setup: I want it to come along with a popup and a popup button and also I want German names for the texts. That does create the same code for the button and the texts and the formatting over and over again, so I wrote my own directive to prevent myself from repeating myself. Here is a plunkr with my directive. However I seem to be doing it wrong. If you choose a date with the
