I am using angular to add some functionality to convert date in another framework (OutSystems). Unfortunately, the framework is calling jquery .load() to do Ajax refresh. This essentially is causing angular binding to break. I do not have any directives or controller. Please find code below. On launching page first tme you should see datetime of Feb 18, 2016 9:51:29 AM but after clicking button and calling.load() it just shows {{ 1455807089244 | date:'medium': 'EST' }}. I tried to use $compiler but it's still doesn't bind. Any help/hint is appreciated.
Note: This a "Test example" to demonstrate the problem.

I think cracked this one... FYI, I have been working on this for days

var elem = angular.element($(selector));
elem.replaceWith($compile(elem)($scope));
$scope.$apply();

I'm starting to study in AngularJs at the beginning level. My project is used in the Spring Boot framework. I get an error message: "ReferenceError: angular is not defined". I have already created app.js which is a defined angular variable, but it is still an error.
app.js:
var app = angular.module('myapp', ['ngRoute']);
app.controller('mainController', ['$scope', function($scope) {
$scope.title = "Welcome";
}]);
welcome.jsp:
<c:set var="contextPath" value="${pageContext.request.contextPath}"/>

How can I resolve this issue?
Move your script below
<c:set var="contextPath" value="${pageContext.request.contextPath}"/>
<!DOCTYPE html>
<html ng-app="myapp" lang="en">
<head>
<meta charset="utf-8">
<title>Create an account</title>
<link href="${contextPath}/resources/css/bootstrap.min.css" rel="stylesheet">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular-route.min.js"></script>
<!-- move it here -->
<script src="${contextPath}/resources/js/app.js"></script>
</head>
<body>
...
</body>
</html>
Add angular script before your app.js.
Since your app.js uses angular object, it must be already defined. angular scripts does that job, so it must be loaded before any angular code.
Try below
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular-route.min.js"></script>
<script src="${contextPath}/resources/js/app.js"></script>
I have written code for simple AngularJS JavaScript but not working properly.
Only root scope is updating but not the other two why I want to update FirstCtrl and SecondCtrl to be updated when I update Root Scope, But this is not working the way I expected.

app.controller('FirstCtrl', function($scope) {

Define controller in module. It will create different scope for different controller.
scope properties must be be in controller you must have an app in first and declare controller in your app.

main.js :
var app=angular.module("myApp",[]);
app.controller("FirstCtrl",function($scope){
});
app.controller("SecondCtrl",function($scope){
});
We can do like this:
angular.module('myApp'[])
.controller('FirstCtrl',FirstCtrl)
.controller('SecondCtrl',SecondCtrl);
function FirstCtrl($scope){
}
function SecondCtrl($scope){
}
In index.html
Give reference main.js and give name of application
<body ng-app="myApp">
I am not able to do data binding using angularJS application.
The following is the HTML template file as databinding.html and Javascript file as invoice.js.
It is priting {{ fname }} {{ lname }} besides John Doe.
<!DOCTYPE html
<html>
<head>
<title></title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<div ng-app="myApp" ng-controller="InvoiceController">
First Name :<input type="text" ng-model='fname' /><br />
Last Name:<input type="text" ng-model='lname' /><br />
{{ fname }} {{ lname }}
</div>
<script type="text/javascript" src="invoice.js"></script>
<script type="text/javascript" src="angular.min.js"></script>
</body>
</html>
angular.module('myApp', []).controller('InvoiceController', ['$scope',
function($scope) {
$scope.fname = 'John';
$scope.lname = 'Doe';
}]);
The order of the scripts is wrong. The controller logic won't work because it doesn't know what angular is yet.
Change this:
<script type="text/javascript" src="invoice.js"></script>
<script type="text/javascript" src="angular.min.js"></script>
to this:
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="invoice.js"></script>
I'm following a tutorial online, but when I refresh my browser I get {{todo.title}} and the checkbox doesn't put a line through the text if clicked.
Any ideas why. I don't see anything different from my code and the video I'm following.
<!doctype html>
<html lang="en" ng-app="ToDo">
<head>
<meta charset="UTF-8">
<title>todo</title>
<style>
.done{text-decoration: line-through;color:#ccc;}
</style>
</head>
<body>
<div ng-controller='todoController'>
<form name="frm" ng-submit="addTodo()">
<input type="text" name = "newtodo" ng-model="newtodo" required>
<button ng-disabled="frm.$invalid">Go</button>
</form>
<button ng-click="clearCompleted()">Clear Completed</button>
<ul>
<li ng-repeat="todo in todos">
<input type="checkbox" ng-model="todo.done" />
<span ng-class="{'done': todo.done}">{{todo.title}}</span>
</li>
</ul>
</div>
<script scr="bower_components/angular/angular.min.js"></script>
<script>
angular.module('ToDo', []).
controller('todoController', ['$scope', function($scope){
$scope.todos = [{'title': 'Build a todo app', 'done':false}];
$scope.addTodo = function(){};
$scope.clearCompleted = function(){};
}]);
</script>
</body>
</html>
you have misspelled src as scr
<script scr="bower_components/angular/angular.min.js"></script>
Please include angularjs file like below. because u not included path of AngularJS Library
<head>
<meta charset="UTF-8">
<title>todo</title>
<style>
.done{text-decoration: line-through;color:#ccc;}
</style>

I'm very new to angular JS. I'm using 1.5x stable version of js. I've started with a simple html code :-
<!DOCTYPE html>
<html data-ng-app="app">
<head>
<title>First JS demo</title>
</head>
<body>
Name :
<br/>
<input type="text" data-ng-model="name" /> {{ name }}
<script src="angular.min.js"/>
</body>
</html>
But while rendering the html in browser im only getting {{ name }} text in data binding expression instead of the actual name value typed in the textbox. I checked that the JS file is loaded correctly in HTML.
Am I doing something wrong? Please help me.
Thanks in advance
You must be define app name and controller name
<!DOCTYPE html>
<html data-ng-app="app">
<head>
<title>First JS demo</title>
</head>
<body ng-controller="myCtrl">
Name :
<br/>
<input type="text" data-ng-model="name" /> {{ name }}
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script>
var app = angular.module('app', []);
app.controller('myCtrl', function($scope, $http) {
});
</script>
</body>
</html>
Or something like this
<!DOCTYPE html>
<html lang="en-US">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>
<div ng-app="">
<p>Name : <input type="text" ng-model="name"></p>
<h1>Hello {{name}}</h1>
</div>
</body>
</html>
