get('url') operation using AngularJS and ServiceStack webservice - javascript

I am very new to AngularJS, and I am trying to get some items in JSON from a webservice I quickly made using ServiceStack. When I try the URL in the browser I can see the JSON object, but for some reason AngularJS fails to successfully get the data. Here's my implementation:
angular.module('SomeApp', []).controller('ItemsFetcher', [ '$http', function($http){
var x = this;
x.products= [
{
Name: 'Missing items',
Description: 'Could not access server'
}];
$http.get('http://localhost:29029/json/reply/GetAllItemsRequest')
.then(function(data){
x.products = [
{
Name: 'Success',
Description: 'Great stuff!'
}];
});
}]);
Here's the view:
<html ng-app="SomeApp">
<head>
<title>My First App</title>
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="app.js"></script>
</head>
<body ng-controller="ItemsFetcher as fetcher">
<h3>PRODUCTS</h3>
<div ng-repeat="item in fetcher.products">
<div>{{item.Name}} - {{item.Description}}</div>
</div>
</body>
As I said, if I call http://localhost:29029/json/reply/GetAllItemsRequest in a browser, I can the JSON object.
Am I missing something ? Any ideas why this does not work ?

In case anyone could benefit from this, I had to either enable CORS (http://en.wikipedia.org/wiki/Cross-origin_resource_sharing) or to host both the webservice and website in the same place.

How to manipulate the <title> of an AngularJS single page app?

I have a single-page AngularJS app.
The index.html file looks like this:
<html ng-app="myApp" ng-controller="MyCtrl as myctrl">
<head>
<link rel="stylesheet" href="my-style-sheet.css">
<title>{{myctrl.title}}</title>
</head>
<body>
<div class="container">
<ol>
<li><a ui-sref="stateA">StateA</a></li>
<li><a ui-sref="stateB">StateB</a></li>
</ol>
<div ui-view></div>
</div>
<script src="my-app.js"></script>
</body>
</html>
As the user clicks on the StateA or StateB links, the page displays the content of those pages in place of <div ui-view></div>. Terrific.
As the user clicks around, the displayed content changes. I need the title of the page to change too. Currently it gets the title from the controller MyCtrl like this: <title>{{myctrl.title}}</title>. But when the user clicks those links, those states each have their own controllers. So I cannot use <title>{{myctrl.title}}</title>.
How can I update the title when various states the user clicks on have different controllers?
You can attach some data to each state of your routes, like a value that can be used to set the title of the page.
.state('test', {
url: '/test',
templateUrl: '/templates/test.html',
data: {
title: 'test title'
}
})
Then write a directive to read the title. You can check to see if the required data is available on the state you are going to, and attach the whole thing to $stateChangeSuccess event.
function dynamicTitle($rootScope, $timeout) {
return {
link: function(scope, el) {
$rootScope.$on('$stateChangeSuccess', function(event, toState) {
var title = (toState.data && toState.data.title)
? toState.data.title
: 'Default title';
$timeout(function() {
el.text(title);
}, 0, false);
};);
}
};
}
angular.module('myApp').directive('dynamicTitle', dynamicTitle);
And attach it to your <title>
<title dynamic-title></title>
You can create an AngularJS factory, inject it, modify it by calling 'Title.setTitle()' from controllers
<html ng-app="app" ng-controller="Ctrl">
<head>
<title>{{ Title.title() }}</title>
app.factory('Title', function() {
var title = 'Hello';
return {
title: function() { return title; },
setTitle: function(newTitle) { title = newTitle }
};
});

Selection in first drop down populates data in second dropdown but only on first click, why?

I have 2 drop downs where selection of first drop down effects the data content of the second drop down.
The problem I have is this functionality is occurring only on first click instead it should happen every time.
Here is my jsFiddle with my working code and here is my code on jsbin(jsbin gives some error which I am unable to understand, help appreciated here too, #newbieTorture).
Thanks in Advance :)

Error in browserbox javascript email code?

I tried using emailjs browserbox to connect to an imap server but the sample script with the correct port and host and username and password just throws out errors and doesn't work in a client-side html file?
https://github.com/whiteout-io/browserbox is a link to the api. What's wrong with how I wrote the code?
<html>
<head>
<title>Test</title>
<!-- Required for non-Unicode encodings -->

Use of Undefined Constant - assumed id

I am new to angularjs and am having some trouble implementing a simple checklist.
<html lang="en" ng-app>
<body>
<div ng-controller="IdController" class="id-contain">
<ul>
<li ng-repeat="id in ids">{{ id.body }}</li>
</ul>
</div>
</body>
</html>
and in my main.js I have
function IdController($scope) {
$scope.id = [
{ body: 'some' },
{ body: 'boiler' },
{ body: 'plate' }
];
}
However, when I load the page, i get Use of undefined constant id - assumed 'id' Any ideas on where I could have gone wrong?
Edit: I have adjusted the name in the controller from $scope.id to $scope.ids to no avail and when I change the {{}} to [[]] it loads [[ id.body ]] 3 times, but not the value. When I run it with {{}} it is giving me the same error and is parsed as <?php echo id.body; ?>
Since many JavaScript frameworks also use "curly" braces to indicate a given expression should be displayed in the browser, you may use the # symbol to inform the Blade rendering engine an expression should remain untouched.
https://laravel.com/docs/8.x/blade#blade-and-javascript-frameworks
Use #before your angular {{}} blocks:
Your code would be like:
<html lang="en" ng-app>
<body>
<div ng-controller="IdController" class="id-contain">
<ul>
<li ng-repeat="id in ids"> #{{ id.body }} </li>
</ul>
</div>
</body>
</html>
That's a problem with blade, you can change laravel's config for blade template token from {{}} to something else like [[]]
Blade::setContentTags('[[', ']]');
Blade::setEscapedContentTags('[[[', ']]]');
Plus, in your angularjs code you should rename $scope.id to $scope.ids in your controller
UPDATE Blade tokens
EDIT OR you can override angular's tags delimiters
DEMO
HTML:
<div ng-app="main">
<div ng-controller="IdController" class="id-contain">
<ul>
<li ng-repeat="id in ids">[[id.body]]</li>
</ul>
</div>
</div>
JS:
angular.module('main', [])
.config(function ($interpolateProvider) {
$interpolateProvider.startSymbol('[[');
$interpolateProvider.endSymbol(']]');
})
.controller('IdController', function ($scope) {
$scope.ids = [
{ body: 'some' },
{ body: 'boiler' },
{ body: 'plate' }
];
});
You html is parsed with the blade parser, if you dont need this page to be parsed with blade parser rename your file from myfield.blade.php to myfile.php

Rendering coordinates on leaflet map view using ajax in ember

[]I am trying to feed data (via an ajax call to a json file) to both a handlebars template and a leaflet map. With my current setup, the data reaches my handlebars template just fine, but doesn't render the coordinates data to the leaflet map. I suspect I am missing some basic piece of the ember.js puzzle. Would someone please advise me?

Ember:
App = Ember.Application.create();
App.Router.map(function() {
// put your routes here
});
App.IndexRoute = Ember.Route.extend({
model: function(){
return App.Item.all();
}
});
App.Item = Ember.Object.extend();
App.Item.reopenClass({
all: function() {
return $.getJSON("js/data/test_e.json").then(function(response) {
var items = [];
response.features.forEach( function (data) {
items.push( App.Item.create(data) );
});
return items;
});
}
});
App.MapView = Ember.View.extend({
didInsertElement: function () {
var map = L.map('map', {zoomControl: false}).setView([40.685259, -73.977664], 14);
L.tileLayer('http://{s}.tile.cloudmade.com/[redacted key]/[redacted id]/256/{z}/{x}/{y}.png').addTo(map);
console.log(this.get('content'));
//HERE IS WHERE I GET STUCK. I CAN OUTPUT THE JSON TO THE CONSOLE...
//BUT HOW DO I DRILL DOWN, AND ULTIMATELY...
//HOW DO I SEND THE VALUE OF THE "CENTER" KEY TO LEAFLET, i.e. L.Marker([jsonObject.center]).addTo(map);
}
});
App.IndexController =
Ember.Controller.extend({});
JSON:
{
"features": [
{
"headline": "Docker, the Linux container runtime: now open-source",
"center" : [40.685259, -73.977664]
},
{
"headline": "What's Actually Wrong with Yahoo's Purchase of Summly",
"center" : [40.685259, -73.977664]
}
]
}
This is the same answer as the other question,
The view is backed by a controller, so you would do this.get('controller') to get the controller which is backed by your collection which if you wanted to get the collection (which isn't necessary since you can iterate the controller) you could do this.get('controller.model').
var controller = this.get('controller');
controller.forEach(function(item){
console.log(item.get('title'));
});
