Can anyone please explain why console.log suddenly stopped to work? I'm trying to debug an exercise for an Angularjs class and at a certain point, console.log was not printing anything anymore.
I'using chrome and my cache is clear.
EDIT:
In this snippet and in Firefox console.log() works but in Chrome does not. How come?
(function () {
'use strict';
angular.module('Ass3', [])
.controller('NarrowItDownController', Narrowdown)
.service('MenuCategoriesService', MenuCategoriesService);
Narrowdown.$inject = ['MenuCategoriesService'];
function Narrowdown(MenuCategoriesService){
var nrdown = this;
var promise = MenuCategoriesService.getMatchedMenuItems();
}
MenuCategoriesService.$inject = ["$http"]
function MenuCategoriesService($http){
var service = this;
console.log("start");
service.getMatchedMenuItems = function(searchTerm){
return $http({
method : 'GET',
url: ("https://davids-restaurant.herokuapp.com/menu_items.json")
}).then(function(result){
var foundname = [];
angular.forEach(result.data.menu_items, function(value, key){
var name = value.name;
//console.log(typeof name);
if (name.toLowerCase().indexOf("chicken") !== -1){
foundname.push(name);
};
});
console.log("end");
return foundname;
});
}
}
})();

You have log placed after return statement
return foundname;
console.log("end");
Just swap this lines like so
console.log("end");
return foundname;
return foundname; should be below console.log()
(function () {
'use strict';
angular.module('Ass3', [])
.controller('NarrowItDownController', Narrowdown)
.service('MenuCategoriesService', MenuCategoriesService);
Narrowdown.$inject = ['MenuCategoriesService'];
function Narrowdown(MenuCategoriesService){
var nrdown = this;
debugger
var promise = MenuCategoriesService.getMatchedMenuItems();
}
MenuCategoriesService.$inject = ["$http"]
function MenuCategoriesService($http){
var service = this;
console.log("start");
service.getMatchedMenuItems = function(searchTerm){
return $http({

url: ("https://davids-restaurant.herokuapp.com/menu_items.json")
}).then(function(result){
var foundname = [];
angular.forEach(result.data.menu_items, function(value, key){

if (name.toLowerCase().indexOf("chicken") !== -1){
foundname.push(name);

console.log("end");

I am in the midst of troubleshooting a webpage that is able to open up a specific title from index.html to titleDetails.html.
However, ng-click in my index.html stopped working all of a sudden. I did not make any changes that could affect the link. It has been working fine all along (redirection of page from index.html to titleDetails.html) .
Original post here
Below are my codes:
app.js
(function () {
angular
.module("BlogApp", [])
.controller("BlogController", BlogController);
function BlogController($scope, $http) {
$scope.createPost = createPost;
$scope.deletePost = deletePost;
$scope.editPost = editPost;
$scope.updatePost = updatePost;
$scope.postDetail = null;
function init() {
getAllPosts();
}
init();
function titleDetails(post){
$scope.postDetail = post;
window.location = "/titleDetails.html";
}
function updatePost(post){
console.log(post);
$http
.put("/api/blogpost/"+post._id, post)
.success(getAllPosts);
}
function editPost(postId){
$http
.get("/api/blogpost/"+postId)
.success(function(post){
$scope.post = post;
});
}
function deletePost(postId){
$http
.delete("/api/blogpost/"+postId)
.success(getAllPosts);
}
function getAllPosts(){
$http
.get("/api/blogpost")
.success(function(posts) {
$scope.posts = posts;
});
}
function createPost(post) {
console.log(post);
$http
.post("/api/blogpost",post)
.success(getAllPosts);
}
}
})();

You are missing $scope.titleDetails = titleDetails; in your controller.
Furthermore, I would recommend using controller as syntax.
So it would be something like this:
index.html
<div class="container" ng-controller="BlogController as blogCtrl">
...
<a ng-click="blogCtrl.titleDetails(post)">{{ blogCtrl.post.title }} </a>
your controller
function BlogController($scope, $http) {
var vm = this;
vm.titleDetails = titleDetails;
//rest of your code using 'vm' instead of '$scope'
This way, you can stop using $scope.
You can find more details here.

I am getting a infinite digest cycle error with the filter code below. What is incorrect with it. I do not see an issue with this. Is there a different method of assignation or is it a known bug? I am not sure whats happening here with this error

My goal is to spin a servo for a certain amount of seconds on a HTML button click. I am using an Arduino Yun as my microcontroller.
When I type in the URL directly the servo spins as it should. When I click on these buttons using the Angular.js GET request nothing happens. Even a regular form submit button works.
Is there something missing from my code?
Is there an easier way to accomplish this?
Here is my front-end code:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css">
<script src="jquery-1.11.1.min.js"></script>

<title>winner's cat Feeder</title>
</head>
<body>
<div ng-controller="ArduinoCtrl" class="container">
<button ng-click="setServo(1)" class="btn">3 Seconds(Food)</button>
<button ng-click="setServo(2)" class="btn">9 Seconds(Food)</button>
</div>
</body>
</html>
<script type="text/javascript">
function ArduinoCtrl($scope, $http)
{
$scope.setServo = function (setting)
{
var url = "http://192.168.1.79/arduino/" + setting
$http.get(url);
}
}
</script>
If I just type in the URL in my browser with the setting value of 1 or 2 the servo works fine.
Please see working demo
var app = angular.module('app', []);
app.controller('ArduinoCtrl', function($scope, $http) {
$scope.response = {};
$scope.progress = false;
$scope.setServo = function(setting) {
$scope.progress = true;
var url = "http://192.168.1.79/arduino/" + setting
$http.get(url).then(sucess, error).then(function() {
$scope.progress = false;
});
function sucess(response) {
angular.copy(response, $scope.response)
}
function error(response) {
angular.copy(response, $scope.response)
}
}
});

You need to add the ng-app directive and add your controller to a module:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css">
<script src="jquery-1.11.1.min.js"></script>
<script src="http://code.angularjs.org/1.2.6/angular.min.js"></script>
<title>winner's cat Feeder</title>
</head>
<body ng-app="myApp">
<div ng-controller="ArduinoCtrl" class="container">
<button ng-click="setServo(1)" class="btn">3 Seconds(Food)</button>
<button ng-click="setServo(2)" class="btn">9 Seconds(Food)</button>
</div>
</body>
</html>
<script type="text/javascript">
function ArduinoCtrl($scope, $http)
{
$scope.setServo = function (setting)
{
var url = "http://192.168.1.79/arduino/" + setting
$http.get(url);
}
}
angular.module("myApp", []).controller("ArduinoCtrl", ArduinoCtrl);
</script>
I've followed this basic AngularJS tutorial : https://www.youtube.com/watch?v=WuiHuZq_cg4&list=PL173F1A311439C05D
Everything went well until I added the clearCompleted() method. it does not seem to be working:

<div ng-controller="TodoCtrl">
<h2>Total todos: {{getTotalTodos()}} </h2>
<ul class="unstyled">

JS:
function TodoCtrl($scope) {
$scope.todos = [
{text: 'Learn Anagular', done:false},
{text: 'Build an app', done:false}
];
$scope.getTotalTodos = function() {
return $scope.todos.length;
};
$scope.addTodo = function() {
$scope.todos.push({text: $scope.formTodoText, done: false});
$scope.formTodoText = '';
};
$scope.clearCompletedTodos = function() {
$scope.todos = _.filter($scope.todos, function(todo) {
return !todo.done;
});
};
}
the "completed todos" are not getting removed .
Here is what I have done and it works for me:
Please notice that the follow lines has been changed (http:// added)

<script type="text/javascript" src="todo.js"></script>
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
I met the same problem, actually, write it like below, it works fine:
$scope.clearCompleted = function(){
$scope.todos = $scope.todos.filter(function(todo){
return !todo.done;
})
};
Actually none of those worked for me; I used this one.
var t = [];
angular.forEach($scope.todos, function (i)
{
if (!i.done)
t.push({text: i.text, done: i.done});
});
$scope.todos = t;
