Hey guys got a little problem that i cant seem to see the problem for. Im building an angular application and im getting the error stated in the question title. Ive injected the $timeout to the controller but im still getting an error with this bit of code can some one tell me where i may be going wrong?
cheers
(function() {
'use strict';
angular
.module('my.module')
.controller('NewSearchController', NewSearchController);
NewSearchController.$inject = ['$rootScope', '$scope', '$location','UserService',
'SearchService', '$window', '$controller', '$mdDialog', 'ModalService', '$routeParams', '$timeout'];
/**
* #namespace ContactController
*/
function NewSearchController($rootScope, $scope, $location, UserService, SearchService, $window, $controller, $mdDialog, $routeParams, $timeout)
Timeout code:
var timerMax = false;
$scope.$watch(NewSearchController.searchObject.maxDayRate, function(){
if(timerMax) {
$timeout.cancel(timerMax);
}
timerMax= $timeout(function() {
NewSearchController.updateSearchFilters();
}, 5000);
});
The problem is in your injection: 'ModalService' listed as injectable but not one of the parameters so angular will inject 'ModalService' and the values you get for parameters later in the list are all wrong.
If you use something like gulp to build your app then use gulp-ng-annotate to build the injection list automatically. That way it won't go wrong and you never have to worry about it.
'$mdDialog', 'ModalService', '$routeParams', '$timeout']
$mdDialog, $routeParams, $timeout
these two dnt match Change it to
$mdDialog,ModalService, $routeParams, $timeout
you have injected $timeout at position 11th position in controller but in function it is at 10th position as u have missed ModalService in function.So the error is just because of this . You need to inject and add the dependcies at same position otherwise it wont work.

I am new to angular and am trying to alter the default behavior of a textangular text input field on my site's backend (I am a guitarist, not a web developer, but can usually figure out what I need to do...). The field has an option to specify a youtube url and then textangular converts that to an image for purposes of editing in the backend. Then in front end textangular has means to have a youtube url displayed correctly as an iframe.
However, on the front end I am not using angular and I read that in my case, to get a youtube embed to show up in front end as iframe you have to use the taApplyCustomRenderers function.
For example, see here:
how to strip placeholder img in textAngular editor in scope var?
In my angular app, here are some of the relevant lines:
angular.module('dashboard')
.controller('EditController', ['$scope', '$http', '$location', '$routeParams', function ($scope, $http, $location, $routeParams) {
$scope.save = function () {
$scope.busy = true;
// I thoguht I could do this:
$scope.somefield = taApplyCustomRenderers($scope.somefield);
// then I would save to model
});
I am getting error that taApplyCustomRenderers is undefined. I thought based on what I read that taApplyCustomRenderers is an available function when using textangular but being new to this I suppose I am missing some key step about injecting the function into the controller or something.
Hoping someone can shed some light.
Thanks in advance!

TLDR; When you try to access taApplyCustomRenderers you are recieving an error since it is not given to this current function, Inject the function and it will work.
The Problem
While I have never actually tried using textAngular, let me explain what the problem is, and from there it should be easy to find the solution.
Your EditController is just a regular javascript function that gets run and attached to the relevant DOM element, so it only has access to functions that are declared in its own scope (or globally).
Here is your exact code just indented differently so you can understand better:
angular.module('dashboard').controller(
'EditController',
[
'$scope',
'$http',
'$location',
'$routeParams',
function ($scope, $http, $location, $routeParams) {
...
$scope.somefield = taApplyCustomRenderers($scope.somefield);
}
]
);
As you can see, the controller function has two parameters, the first being a string and the second an array, and the last element in the array is just a regular function.
The solution
Checking the textAngular documentation I saw that the taApplyCustomRenderers is a factory, which means you can inject it into your controller function as so:
angular.module('dashboard').controller('EditController',
['$scope', '$http', '$location', '$routeParams', 'taApplyCustomRenderers',
function ($scope, $http, $location, $routeParams, taApplyCustomRenderers) {
taApplyCustomRenderers(); // is now Available.
}
]);
I'm trying to inject my factory into my controller and I'm getting this error from AngularJS:
Error: $injector:unpr Unknown Provider
I have looked through almost all of the questions on here and still cannot find a solution to my problem. I believe my controller and factory and declared correctly and the injection is correct but it looks like this isn't the case.
My factory code is as follows:
var app = angular.module('test', []);
app.factory('processingFactory', function () {
var factory = {};
factory.newTest = function() {
console.log("TEST");
}
return factory;
});
This is then injected into the controller which looks like this:
angular.module("test", ["angularModalService", "anguFixedHeaderTable",
'angular-loading-bar', "ngResource", "agGrid",
'ui.tree']).controller("dashboardController", [
"$scope",
"$timeout",
"$http",
"$window",
"$interval",
"$resource",
"ModalService",
"$filter",
'$q',
'processingFactory',
function($scope, $timeout, $http, $window, $interval, $resource,
ModalService, $filter, $q, processingFactory) {
//other code removed
$scope.newWorkorder = processingFactory.newWorkorder;
}
]);
This function is called through a button click on the web page. All of the files needed are in script tags on this html page. I am fairly new to angular so this could be a simple error or something I am not aware of.
Calling angular.module with an array as the second argument declares a module, which can only happen for any given module name. You are declaring the module twice (once in your controller code, and again in your factory code).
Try changing the first part of your factory code to:
var app = angular.module('test');
If you are doing the same thing elsewhere in the app you will need to remove the second argument there too, so that there is only one module declaration in the whole app.
if there are any dependencies for your module "test" why do not you have them declared in the first line itself like:
var app = angular.module("test", ["angularModalService", "anguFixedHeaderTable",
'angular-loading-bar', "ngResource", "agGrid",
'ui.tree']);
Then declare your controller like::
app.controler(...)
Things should work fine.
I need a function where I can use $window.history.back() to be called from every view regardless of what controller is controlling that page.
.run(['$rootScope', '$state', 'CommonUserModel', 'InitialiseService','$window', function($rootScope, $state, $window, commonUserModel, initialiseService) {
$rootScope.link = function(){
$window.history.back();
};
So I have this function put in the app module. Injected window object because it complained about it. But now it also complains that it "Cannot read property 'back' of undefined".
I am calling this function with $rootScope from other controllers as I read through StackOverflow. I had to inject $rootScope to other controllers like this.
homeViewModule.controller("simDetailsController", [ '$rootScope','$scope', 'ModalDialogService', 'CommonTagModel', '$location','$window',
function($scope, modalDialogService, commonTagModel, $location, $window,$rootScope) {
self.link = function(){
$rootScope.link();};
Can you give me an advice?
Keep in mind that I am pretty newbie on AngularJS I still don't get this messy, complex framework.
The order in which you have injected $window & $rootScope in the parameters list does not match the string array list.
You have mentioned '$window' as the 5th element in the string array, while, it is the 3rd element in the parameters list.
Also, in your code, '$rootScope' is the 1st element in the string array, while, it is the 6th element in the parameters list.
Replace the first lines in both of your code snippets with these:
.run(['$rootScope', '$state', 'CommonUserModel', 'InitialiseService','$window', function($rootScope, $state, commonUserModel, initialiseService, $window) {
homeViewModule.controller("simDetailsController", [ '$rootScope','$scope', 'ModalDialogService', 'CommonTagModel', '$location','$window',
function($rootScope, $scope, modalDialogService, commonTagModel, $location, $window) {
You should use routes:

I want to make a promise in my angularjs controller. I took the example from the Angularjs Doc and pasted it in my controller. When I try to run the code, the console prints:
Error: $q is not defined
Why is this error happening and how do I solve it?
I tried to google this problem, but most questions revolve about more specific problems than mine.
A (german) guide tells me that promises are already in angular js implemented and there is no need to add anything to it.
EDIT:
this is my controller:
app.controller("ArgumentationController", [
'$scope', '$resource',
function($scope, $resource) {
EDIT2:
A commentor suggested to inject $q. I did this:
app.controller("ArgumentationController", [
'$scope', '$resource', '$q',
function($scope, $resource, $q) {
Now, the error does not occur.
From your past code, no need of $resource in your code. Instead inject $q in it.
As you are creating a dummy promise using $q, make following changes.
app.controller("ArgumentationController", [
'$scope', '$q',
function($scope, $q) {
I'm new to angular and have the following code.
angular.module('MyApp')
.controller('loginController', ['$scope', '$http', 'conditionalDependency',
function ($scope, $http, conditionalDependency{
}
I would like to have conditionalDependency loaded conditionally. Something like this
if(true)
{
//add conditionalDependency
}
How can this be done. I've seen this post . However, my requirement is that I have the dependency specified in function
Thanks in advance.
Not quite clear as to why you would have to have it in a named function like in your example but...
If you need conditional dependencies, I would suggest taking a look at the following:
Conditional injection of a service in AngularJS
I've used this method in a couple niche scenarios and it works quite well.
EXAMPLE:
angular.module('myApp').controller('loginController',
['$injector', '$scope', '$http',
function($injector, $scope, $http) {
var service;
if (something) {
service = $injector.get('myService');
}
});
You can use it even without injecting injector in your controller
if(something){
var injector = angular.element(document).injector();
var myService = injector.get('myService')
}
Use:
angular.injector().get('conditionalDep');
You can inject $injector once to your file and call $injector.get('dep');
