I have researched my issue and tried many solutions but have not solved it.
For some reason angular does not seem to be loading in plunker.
I have head iffy are no longer supported in later version in angular, but I have tried loading an older version and still does not work.
Any ideas on how I can get this running?

var app = angular.module("githubViewer", []);
var MainController = function($scope, $http) {
var onUserComplete = function(response){
$scope.user = response.data;
};
var onError = function(reason){
$scope.error = "Could not fetch the user request!";

$http.get("https://api.github.com/users/robconery")
.then(onUserComplete, onError);
$scope.message = "Hello, Angular!";

app.controller("MainController", ["$scope", "$http", MainController]);
Replace angular-bootstrap-prettify.js (I don't know what is angular-bootstrap-prettify, do you really need it?) by angular.js and your plunkr works.

I need to run this code in angularjs.
When I try to execute this model function it is not running.
It is not even showing alert or console.
So what is the way to use this script files in angularjs
Here is my code in example.html:
<div>
{{sample}}
</div>
<div><button ng-click="name()"></div>
<script>
function name(){
alert("text");
}
</script>
If i understand your requirement correctly,
You need to execute a separate java-script function.
For an angular application it is not a proper way to run javascript out of scope of angular.
any if it is absolutely requried you can try replacing ng-click="name()" with onclick="name()"
var app = angular.module("app", []);
app.controller('exampleController', [function() {
this.myFunction = function() {
alert("Iam from angular controller");
}
}]);
function myFunction() {
alert("Iam from javascript");
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<div ng-app="app" ng-controller="exampleController as ctrl">
<button ng-click="ctrl.myFunction()">click me</button>
<button onclick="myFunction()">click me</button>
</div>
#Update
If you want to use a java script library or function or constants in angularjs the my suggested way is to add a factory or service that ensure the library or function or constants but it is not simple as above solution.Here iam adding a snippet based on above solution
There are some advantages of using following approch :-
It will add dependency injection proprely which is a basic concept behind angularjs
It will ensure that the external function exist before starting app.
It will add more flexibility and control over the java script function in angular.
The below snippet will remove the external access of function and secure your application
This is the best way in which you can add external libraries like jquery loadash or any js libraries to your code
(function() {
function exampleController(myFunction) {
this.myFunction = function() {
alert("Iam from angular controller");
}
this.externalJSFunction = myFunction
};
exampleController.$inject = ['myFunction'];
function myFunctionFactory($window) {
if (!$window.myFunction) {
throw new Error("myFunction is not defined");
}
this.myFunction = $window.myFunction;
/* You can add
$window.myFunction = undefined;
if the function ($window.myFunction) is not required by
some other library or function in window scope
in such cases it gives added security by
restricting access of this from window scope and dis allows modification
*/
return this.myFunction;
}
myFunctionFactory.$inject = ['$window'];
var app = angular.module("app", []);
app.controller('exampleController', exampleController);
app.factory('myFunction', myFunctionFactory);
})();
function myFunction() {
alert("Iam from javascript");
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<div ng-app="app" ng-controller="exampleController as ctrl">
<button ng-click="ctrl.myFunction()">click me For angular Function</button>
<br/>
<button ng-click="ctrl.externalJSFunction()">click me For external JS Function </button>
<br/>
<button onclick="myFunction()">click me for checking exteranl acess </button>
</div>
your code should be like this....
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');</script>
<link rel="stylesheet" href="style.css" />
<script data-require="angular.js#1.4.x" src="https://code.angularjs.org/1.4.12/angular.js" data-semver="1.4.9"></script>
<script >
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name=function(){
alert("text");
}
});
</script>
</head>
<body ng-controller="MainCtrl">
<div>
{{sample}}
</div>
<div><button ng-click="name()">click me</div>
</body>
</html>
You need to give angular js cdn first and then a create a module and controller like above
Here is a sample controller.
<body ng-app="myApp" ng-controller="myCtrl">
<div>
<button ng-click="name()">
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.name = name;
function name(){
alert("text");
}
});
</script>
</body>
You could use a directive, here is an example:
// in your JS source
angular.directive('something', [function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
element.bind('click', function() {
alert('yup');
});
}
};
}]);
// in your HTML file
<button type="button" something>Click Me!</button>
This allows you to reuse your various code chunks / functions across your entire project pretty easily.
Another Solution
<!DOCTYPE html>
<html>
<head>
<title>example</title>
<script data-require="jquery#*" data-semver="3.1.1" src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
</head>
<body ng-app="app" ng-controller="exampleController as ctrl">
<button ng-click="ctrl.name()">click me to angular</button>
<button ng-click="name()" class="btn">click me to javascript</button>
<script>
var app = angular.module("app", []);
app.controller('exampleController', [function() {
this.name = function() {
alert("angular text");
}
}]);
//JQuery Lib must be included your project
$(document).on('click', '.btn', function() {
eval($(this).attr('ng-click'));
});
function name() {
alert("javascript text");
}
</script>
</body>
</html>
You should be able to run any javascript inside of an angular controller inside of a script tag in an html file.
Your html file should look something more like this:
<!DOCTYPE html>
<html>
<head>
<title>example</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
</head>
<body ng-app="app" ng-controller="exampleController as ctrl">
<button ng-click="ctrl.name()">click me</button>
</body>
</html>
<script>
var app = angular.module("app", []);
app.controller('exampleController', [function() {
this.name = function(){
alert("text");
}
}]);
</script>
Create a service layer and glue it inside the controller. Now, you can reuse the created function in multiple controllers.
For implementation,
How can I call javascript function in AngularJS controller?
I hope this helps!
I have a very basic example that isn't working: I have two aspects, the index.html and the main.js. They are in the same folder:
<!DOCTYPE html>
<html>
<head>
<title> AngularJS Tutorials </title>
<link rel="stylesheet" href="css/foundation.min.css">
<script src="main.js"></script>
</head>
<body>
<div ng-app="myApp">
<div ng-controller="FirstCtrl">
<h1>{{data.message}}</h1>
</div>
</div>
<script type="text/javascript" src="js/angular.min.js"></script>
</body>
</html>
main.js
function FirstCtrl($scope) {
$scope.data = {message: "Hello"};
}
my page shows this:
{{data.message}}
You need to add the controller to the angular module. you can use the controller function to add the js function for your controller.
var FirstCtrl = function FirstCtrl($scope) {
$scope.data = {message: "Hello2"};
};
angular.module("myApp",[]).controller("FirstCtrl",FirstCtrl);
If you already had the angular module defined somewhere else in the page, Use this version.
angular.module("myApp").controller("FirstCtrl",FirstCtrl);
Here is a working sample http://jsbin.com/tiroteharu/edit?html,js,console,output
<script src="~/Scripts/angular/angular.js"></script>
<script>
var myApp = angular.module('myApp', []);
myApp.controller('FirstCtrl', ['$scope', function ($scope) {
$scope.data = { message: "Hello" };
}]);
</script>
<div ng-app="myApp">
<div ng-controller="FirstCtrl">
<h1>{{data.message}}</h1>
</div>
</div>

I'm new to Angular JS.
I have a few questions. Scope seems to be working with my first controller testController but not with my second controller controlspicy.
Why is not letting me print out $scope.greeting ? Shouldn't the binding work because I assigned a controller.
Here's a plunkr link which directs straight to the code.
http://plnkr.co/edit/NbED8vXNiZCqBjobrISa?p=preview
<!DOCTYPE html>
<html ng-app="newtest">
<head>
<script data-require="angular.js#*" data-semver="1.3.5" src="https://code.angularjs.org/1.3.5/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
<script src="spicy.js"></script>
</head>
<body ng-controller="testController">
<h1>Hello Plunker! {{message}}</h1>
<input type="text" name="firstName" ng-model="thetext">
{{double(thetext)}}
<h1 ng-controller="controlspicy">new test</h1>
<h2>{{greeting}}</h2>
</body>
</html>
script.js
var app = angular.module("newtest", [])
.controller("testController", ["$scope", function($scope) {
$scope.message = "hola";
$scope.double = function(value){
if (value == null){
return 0;
}
return value*2;
};
}]);
spicy.js
var appl = angular.module("thespicy", [])
.controller("controlspicy", ["$scope", function($scope){
$scope.greeting = "hello";
}]);
As previously mentioned by Preston you need to wrap the <h2> inside a tag with ng-controller. There is one more issue however.
controlspicy is defined in another module than the one you specify in ng-app.
Change angular.module("thespicy", []) in spicy.js to angular.module("newtest").
You should almost never use more than one module in one app. You could however divide it into different sub-modules but if your new to Angular I would recommend using just one module to start with.
To clarify; you should only define a module once by typing angular.module("module_name", []). Notice the [] here. In this array you would put dependencies for the module (if you really wanted the 'thespicy' module you could have included it as a dependency with angular.module("newtest", ['thespicy']). If you later wanted to add a controller to the module you would reference the module with angular.module("module_name") (no []). For example:
// Define a module
angular.module('foo', []);
// Reference the previously defined module 'foo'
angular.module('foo')
.controller('barCtrl', function() { ... });
Here is a working fork of your example: http://plnkr.co/edit/rtUJGeD52ZoatoL3JgwY?p=preview btw.
The nested controller only controls inside the scope of the tag. In this case, it only has access to the scope inside of the h1 tag.
Try this:
<!DOCTYPE html>
<html ng-app="newtest">
<head>
<script data-require="angular.js#*" data-semver="1.3.5" src="https://code.angularjs.org/1.3.5/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
<script src="spicy.js"></script>
</head>
<body ng-controller="testController">
<h1>Hello Plunker! {{message}}</h1>
<input type="text" name="firstName" ng-model="thetext">
{{double(thetext)}}
<div ng-controller="controlspicy">
<h1>new test</h1>
<h2>{{greeting}}</h2>
</div>
</body>
</html>
Here's a working plunker of your example: http://plnkr.co/edit/gufbBI4i68MGu8FWVfJv?p=preview
I should point out that you didn't include your controller in your main app.
script.js should start like this:
var app = angular.module("newtest", ['thespicy'])
You have multiple apps
check this plunkr for working nested controllers
<div>
<div ng-controller="testController">
<h1>Hello Plunker! {{message}}</h1>
<input type="text" name="firstName" ng-model="thetext">
{{double(thetext)}}
</div>
<div ng-controller="thespicy">new test
<h2>{{greeting}}</h2>
</div>
</div>
script.js
var app = angular.module("newtest", [])
.controller("testController", ["$scope", function($scope) {
$scope.message = "hola";
$scope.double = function(value){
if (value == null){
return 0;
}
return value*2;
};
}])
.controller('thespicy', ["$scope", function($scope) {
$scope.greeting = "Hello";
}])
I couldn't get my angular code to run in plunker. I have attached the details. Could any of you help me out? Basically it's a problem with ngcontroller I guess but I am not sure.

Plunk

In version 1.3.*, you cannot longer declare a global controller function.
Instead define a module, and use your controller function:
var SidController = function($scope){
$scope.message = "WElcome.";
};
SidController.$inject = ['$scope'];
angular.module('app', []).controller('SidController', SidController);
In your html
<html ng-app="app">
See this plunker.
I had the same issue.. Well done on starting a tutorial! Simply replace the script in your index.html with
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.2/angular.min.js"></script>
I suppose the library Plunker currently has is outdated or something.
Working Plunkr (with a different AngularJS version. #user3906922 has a better answer, where your version stays the same).
Use this for HTML for instance:
<!doctype html>
<html ng-app>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div ng-controller="SidController">
<h1>Hello Plunker!</h1>
{{ 5 / 2 }}<br>
{{message}}
</div>
</body>
</html>
Check this plunkr
You need to define your module and then register the controller
http://plnkr.co/edit/9zAV5nSWH05FYscEWYZ5?p=preview
angular.module( 'demoApp', []);
angular.module( 'demoApp' )
.controller( 'SidController', function($scope){
$scope.message = "WElcome.";
});
You should create your module.
angular.module('app', []).controller("SidController", function($scope) {
$scope.message = "WElcome.";
});
Then in your html element, set your attribute like this:
ng-app="app"
Here is my code :
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<script type="text/javascript" src="./angular.min.js"></script>
<script>
var app = angular.module('myApp', []);
var app1 = angular.module('myApp1', []);
app.controller('myCtrl', function($scope) {
$scope.firstName = "sparsh";
$scope.lastName = "khandelwal";
});
</script>
<title>Home Page</title>
</head>
<body>
<div ng-app="myApp" ng-init="name='Sparsh'">
<div ng-controller="myCtrl">{{firstName}}</div>
<p>
Name : <input type="text" ng-model="name">
</p>
<h1>Hello {{name}}</h1>
</div>
<div ng-app="myApp1" ng-init="names=['Jani','Hege','Kai']">
<ul>
<li ng-repeat="x in names">{{x}}</li>
</ul>
</div>
<script type="text/javascript">
angular.bootstrap(document, ['myApp1','myApp']);
</script>
</body>
</html>
Although i can see the expected output, but at the same time facing console error.
here is the description of error
(while i click on the url)
it says it already bootstrapped so i remove the 'myApp' from .bootstrap function, but that didnt work.
Please help.
You are doing both ng-app declarations and angular.bootstrap(document, ['myApp1','myApp']);.
You need to choose only one method, otherwise you get the well descripted error of multiple bootstrapped applications.
The problem is as explained in the previous comments, the automatic and manual initialization of modules.
Since you want to initialize them separately for each elements then try an approach like
<div data-app="myApp" ng-init="name='Sparsh'">
<div ng-controller="myCtrl">{{firstName}}</div>
<p>
Name : <input type="text" ng-model="name"/>
</p>
<h1>Hello {{name}}</h1>
</div>
<div data-app="myApp1" ng-init="names=['Jani','Hege','Kai']">
<ul>
<li ng-repeat="x in names">{{x}}</li>
</ul>
</div>
then
var app = angular.module('myApp', []);
var app1 = angular.module('myApp1', []);
app.controller('myCtrl', function ($scope) {
$scope.firstName = "sparsh";
$scope.lastName = "khandelwal";
});
var els = document.querySelectorAll('[data-app]');
for (var i = 0; i < els.length; i++) {
angular.bootstrap(els[i], [els[i].dataset.app]);
}
