I am new on AngularJS and I got that error. Here is my code:
app.factory('NotificationService', function($http){
var factory = {};
factory.getNotificationList = function($http){
var url = "";
return $http.get(url);
}
return factory;
});
app.controller('NotificationListController', function($scope,$http, NotificationService) {
var notificationList = NotificationService.getNotificationList();
notificationList.then(function(response){
console.log(response);
$scope.notificationData = response.data;
return response;
});
});
I am so confuse where my mistake is. The error message is:
TypeError: Cannot read property 'get' of undefined at Object.factory.getNotificationList ()

You are getting this error because $http is undefined in your factory.
You can fix it by passing it to the factory like so:
app.factory('NotificationService', ['$http', function ($http) {
var factory = {};
factory.getNotificationList = function() { // Remove the `$http` parameter from here.
var url = "";
return $http.get(url);
}
return factory;
}]);
Simple possible reason is $http is passed twice. When you pass any argument to the function, the closure for those variable changes
var a =10;
var b= 20;
var abc = function()
{
document.getElementById("first").innerHTML = a + b;
}
var pqr = function(a,b)
{
document.getElementById("second").innerHTML = a + b;
}
abc();
pqr();
In this example, though variable a,b declared, second function pqr() will return NaN, until we pass an argument, explicitly
