For some reason, it would seem that "User.Identity.IsAuthenticated" is either false or undefined as far as angular is concerned, as my "Hello, #ViewBag.User" is never visible. But the "User.Identity.IsAuthenticated" above that, which shows my main menu, works fine.
I assume I'm missing something silly, but I can't seem to figure out what, as I'm doing it the same as another article on here instructed.
add # before the 2nd User.Identity.IsAuthenticated
Correction: should be '#User.Identity.IsAuthenticated' === 'True'
However, Razor doesn't like ng-** so they should be used as data-ng-**, to prevent razor from parsing those

This is the code.
(I know that I must type here so many text to post my question, but please ignore this part in the parenthesis. It is due only to the rules of the site.)
I can not find the reason, but on screen only appears "{{adat}}".

It turned out that this version of Angular works with a newer syntax.
For this syntax the appropriate version is 1.0.0
I'm trying Angular for the first time, and my first issue that I want to implement is single page application feature.
But here the first problem:
I have configured a very simple work, it is divided into two files: index.html and project.js.
I'm working on a Windows 10 machine and I'm using xampp 3.2.2, this project is putted inside the folder /htdocs/webapp.
When access to "localhost/webapp/" it properly load the "otherwise" condition, but when I try to load for example "localhost/webapp/#/tomato" or "localhost/webapp/#tomato" the url becomes "http://localhost/webapp/#!#tomato" and the page still shows the content of the otherwise condition...
I really don't know what is the cause, and also the console doesn't show any errors, it seems that in $routeProvider always get the otherwise condition.
Please guys, give some solutions I'm very nervous ;-)
Thank you

I have a simple rails application., Hoping to get some input for this block of code that is not working.
<div ng-contoller="myappMyController as myController">
Hello {{ myController.greet() }}
</div>
I have a controller defined in angular amp.js. Here is the source code for that js file
var MyController= function() {
console.log("AM getting here");
var controller=this;
var greet = function () {
return "howdy";
}
controller.greet=greet;
}
angular.module('myapp',[]).controller('MyController', MyController);
Here is the html file where am calling this method
<div ng-app>
<p id="notice"><%= notice %></p>
<h1>Listing Users</h1>
<p>The value is {{1+1}}</p>
<input ng-model="firstName" ng-model-options="{updateOn: 'blur'}"/>
<p>Hi {{firstName}}</p>
<div ng-contoller="myappMyController as myController">
Hello {{ myController.greet() }}
</div>
</div>
The copy of the application layout html file is
<!DOCTYPE html>

Any recommendations or things I have not addressed.
Here you have defined your controller as MyController:
angular.module('myapp',[]).controller('MyController', MyController);
Here you are trying to reference it as myappMyController (plus you have a typo on ng-controller):
<div ng-contoller="myappMyController as myController">
You need to change one or the other so they both match either MyController or myappMyController.
I am trying to display a plain html/css loading spinner on first load in my Angular APP. The spinner code is included in my index.html.
However, the dom seems not to be rendered until my angularjs APP starts kicking in, causing a very lengthy display of a white screen until this finally happens. Is there any way to prevent that?
I would like to understand how to load my plain html/css spinner right after the css code in the head is done loading so as to improve user experience.
Test on webpagetest.org seem to confirm this diagnosis (the /settings, /introductions, /menus lines are all calls to an external API done by an AngularJS service before render):
Here is a simplified version of my build code:
<!DOCTYPE html>
<html ng-app="app">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge, chrome=1" />
<title ng-bind="($title || 'Home') + ' - WalktheChat'">WalktheChat</title>
<link rel="stylesheet" href="styles/lib.css">
<link rel="stylesheet" href="styles/app.css">
</head>
<body>
<div id="base-container" ng-controller="Shell as main">
<div ng-include="'app/layout/header.html'"></div>
<div id="content" ui-view ng-cloak autoscroll="true"></div>
<div ng-include="'app/layout/footer.html'"></div>
</div>
<!-- This is the spinner I would like to display on first load -->
<div ng-show="::false" class="spinner-container">
<div class="spinner sk-spinner sk-spinner-pulse"></div>
</div>
<script src="js/lib.js"></script>
<script src="js/app.js"></script>
</body>
</html>
whatever the complexity of your application,all your controllers are within the same angular application, all scopes within the same application inherits from the same root, whatever you define on the $rootScope will be available to all child scopes.
we have two ways to resolve this problem:
use $broadcast(), $emit() and $on() that facilitate event driven publisher-subscriber model for sending notifications and passing data between your controllers.(professional solution)
declare $rootScope variable and watching changement.(simple way)
It turns out the problem was coming from "render-blocking javascript", I had to add the "async" tag to my JS to fix it.
When adding async to both my lib.js and app.js, I had an issue with app.js loading before angular scripts were loaded (thus causing the APP to throw an error). In order to solve this issue, I combined my lib.js and app.js into one single file and then added the async tag.
My final build code looks like that (the magic happens on the final "script" tag):
<!DOCTYPE html>
<html ng-app="app">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge, chrome=1" />
<title ng-bind="($title || 'Home') + ' - WalktheChat'">WalktheChat</title>
<link rel="stylesheet" href="styles/lib.css">
<link rel="stylesheet" href="styles/app.css">
</head>
<body>
<div id="base-container" ng-controller="Shell as main">
<div ng-include="'app/layout/header.html'"></div>
<div id="content" ui-view ng-cloak autoscroll="true"></div>
<div ng-include="'app/layout/footer.html'"></div>
</div>
<!-- This is the spinner I would like to display on first load -->
<div ng-show="::false" class="spinner-container">
<div class="spinner sk-spinner sk-spinner-pulse"></div>
</div>
<!-- This app.js now also contains lib.js from my question !-->
<script src="js/app.js" async></script>

I am new to Fuel UX and trying to make checkbox work. I have the following simple page:
<!DOCTYPE html>

<body>
<div class="checkbox" id="myCheckbox">
<label class="checkbox-custom" id="myCustomCheckbox1">
<input class="sr-only" type="checkbox" value="">
<span class="checkbox-label">Custom checkbox unchecked on page load 22234</span>
</label>
</div>
<script>
//javascript initialization goes here
</script>
</body>
</html>
I need to initialize the checkbox via Javascript. The following works:
$('#myCustomCheckbox1').checkbox();
The following are not working:
$('input[type="checkbox"]').each(function(index, item) {
$(this).checkbox();
});
or
$('input[type="checkbox"]').checkbox()
Could any expert confirm that checkboxes must have id if they are initialized via Javascript? Or I did it in a wrong way?
Please review the documentation. The checkbox jQuery plugin can only be bound to the label, not the wrapping div (if present), nor the input.
You might try:
$('.checkbox > label').each(function(index, item) {
$(this).checkbox();
});
