Certain chars and text after that gets rejected when using ng-bind-html along with $sce.trustAsHtml. Any Ideas on taclking this issue?
Controller
angular.module('myApp', []).controller('IndexController', ['$scope', '$sce', function($scope, $sce){
$scope.text= $sce.trustAsHtml('TEST>19 XYZ </= This is not showing up in ng-bind-html />');
}]);

This is invalid html, the < and > should be encoded as html entities : > <
If you just put this html in a page, the display is the same (please run the very simple snippet below). The browser just doesn't know what to do with this tag.
TEST>19 XYZ </= This is not showing up in ng-bind-html />

Newbie to AngularJS. Trying to display a message from controller onto the html page but it does not show. I'm using AngularJS version 1.6.0 and I binded the controller to the body tag. What am I missing?
/// HTML
<!DOCTYPE html>
<html ng-app="app">
<head>
<script data-require="angular.js#*" data-semver="4.0.0"
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.10/angular.min.js">
</script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
// script.js file contents
var app = angular.module('app', []);
app.MainController('MainController', function($scope) {
$scope.message = "Hello, Angular!";
});
Thank you.
Since you are using the version 1.6 , declaration of global controller is not supported, you need to have a module as well.
DEMO
var app = angular.module('testApp',[])
app.controller('MainController',function($scope) {
$scope.message = "Hello, Angular!";
});
<!DOCTYPE html>
<html ng-app="testApp">
<head>
<script data-require="angular.js#*" data-semver="4.0.0"
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.10/angular.min.js">
</script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
do you need to pass the name of your app on the ng-app tag.
Like this:
<html ng-app="your-app">
So Angular understand where it comes.
So, an advice to you is using the controllerAs syntax over the classic controller with $scope syntax.
Like this:
JS file:
var app = angular.module('testApp',[])
app.controller('MainController',function($scope) {
var vm = this; // view model
vm.message = "Hello, Angular!";
});
HTML file:
<body ng-controller="MainController as mainCtrl">
<!-- or any other name, your choice -->
<h1>{{mainCtrl.message}}</h1>
</body>
Why?: Controllers are constructed, "newed" up, and provide a single
new instance, and the controllerAs syntax is closer to that of a
JavaScript constructor than the classic $scope syntax.
Why?: It promotes the use of binding to a "dotted" object in the View
(e.g. customer.name instead of name), which is more contextual, easier
to read, and avoids any reference issues that may occur without
"dotting".
Why?: Helps avoid using $parent calls in Views with nested controllers

I hope this helps you
I have a input text like in one page. I would like to store the information from this input with angular, so when moving to another page I could display it in another input text.
I have tried with ng-model and ng-init
<input type="text" ng-model="inputText" ng-init="userText">
Having in the controller
$scope.userText = $scope.inputText;
But it doesn't seem to work. You can see a working plunker here. Thanks in advance!
PS: I need to do it between two pages (not with a single page and then routing).
basically what happens is that your variables are reseted when you change page. You can achieve what you want using localstorage. Here follows an example
JS:
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.saved = localStorage.getItem('userText');
$scope.userText = (localStorage.getItem('userText')!==null) ? $scope.saved : "";
$scope.editText = function(){
localStorage.setItem('userText', $scope.userText);
}
});

You can store in rootscope/ localstorage/ URL as parameter . The retrieve value on your destination page

I am not able to figure out why angular variables are getting displayed as normal text instead of its assigned value. kindly help...
It looks like you are missing a link to your app.js file.
Just a tip when referencing your .js files, make sure you reference any javascript which uses Angular AFTER the line where you reference angular.js
So your references should look something like this:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
<script src="app.js"></script> <!-- this is the one you are missing -->
Please, plunkr
It works
<h1>{{main.title }}</h1>
<div ng-controller='SubController as sub'>
<h2>{{sub.title}}</h2>
<p>If we were not using the <strong>ControllerAs</strong> syntax we would have a problem using title twice!</p>
</div>
I am new to web development, trying to learn angularjs, and got stuck at very first step, this code works fine when I remove ng-controller but in this condition the browser shows Hello, {{name}}.
What am I doing wrong?

<!DOCTYPE html>
<html lang="en" ng-app="app" ng-controller="AppCtrl" >
<head >
<script src="js/angular.min.js"></script>

<h1>Hello, {{name}}</h1>
<input type="text" ng-model="name">

</html>
controller.js
function AppCtrl($scope)
{
$scope.name: "world";
}
You are calling module named app which you didn't declared.
<html lang="en" ng-app="app" ng-controller="AppCtrl" >
If you provide module name then controller have to bind with that module.
To assign a value you have to use = not :
$scope.name: "world";
Try Like this
$scope.name= "world";
Moreover Global controller isn't allowed from 1.3.x
Try like this
var app = angular.module("app", []);
app.controller("AppCtrl", function($scope) {
$scope.name= "world";
});

i have routeProvider, ng-view and controller.
Simple template with form and input. I can see $dirty value in {{form.var1.$dirty}} - it changes when i type, but how to access it in the controller code?
html main

<html ng-app="project">

check dirty
<form class="form-horizontal" novalidate name="form" ng-submit="submit()">
<input id="var1" name="var1" class="input" type="text" ng-model="var1">
</form>
js
angular.module('project',[]).
config(function($routeProvider) {
$routeProvider.
when('/', {controller:Ctrl1, templateUrl:'dirty_tab.html'}).
when('/tab1', {controller:Ctrl1, templateUrl:'dirty_tab.html'}).
otherwise({redirectTo:'/'});
});
function Ctrl1($scope,$rootScope) {
$scope.var1=100;
$scope.dodo1 = function() {
alert(form.var1.$dirty);
}
}
Alert shows me "undefined".
How to get var1 $dirty value?
As Cherniv told you in the comments you need to access the variable from the $scope object
$scope.form.var1.$dirty
