(function () {
var sample = angular.module('notifyApp', ['ngRoute']);
sample.service('notifications', ['$rootScope', function ($rootScope) {
var queue = [];
return {
queue: queue,
add: function (item) {
var index = -1;
for (var i = 0; i < this.queue.length; i++) {
if (queue[i].body == item.body) {
index = i;
break;
}
}
if (index != -1)
return;

Points of Interest
- Same type of notifications is only active on screen once in case of multiple clicks.
- Close button result in removal of notification from queue.
- Timeout value can be increased or decreased as per need.
