Following Code is not showing or updating the value of nam in <p> tag. Kindly help !
<html ng-app>
<head></head>
<body>
<input ng-model = "nam.a" ng-controller = "myControl">
<p> Hello {{nam.a}} </p>
<script>
function myControl($scope){
$scope.nam = {
a : "abcdefg"
};
};
</script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular.min.js"></script>
</body>
</html>
You should specify the app module in html page.
<html ng-app="Test">
<body ng-controller = "myControl">
<input ng-model = "nam.a"/>
<p> Hello {{nam.a}} </p>
Then inject the module and controller like as below.
var app = angular.module('Test', []);
app.controller('myControl', function($scope) {
$scope.nam = {
a : "abcdefg"
};
});
In your code there is no ng-app created, ng-controller is binded in wrong way also. This is the right implementation. Look at the example.
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="myControl">
<input ng-model="nam.a" >
<p> Hello {{nam.a}} </p>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myControl', function ($scope) {
$scope.nam = {
a: "abcdefg"
};
});
</script>
</body>
</html>
you should write like this
<body ng-controller="myControl">
<input ng-model = "nam.a">
<p> Hello {{nam.a}} </p>
</body>

<body ng-app="yourAppName">
<div ng-controller="myControl">
<input ng-model="nam.a">
<p> Hello {{nam.a}} </p>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular.min.js"></script>
<script>
angular.module('yourAppName', [])
.controller('myControl', function($scope) {
$scope.nam = {
a: 'abcdefg'
}
});
</script>
</body>
</html>
use angular to create a module (in the example, I called it yourAppName), which you reference in the HTML in the ng-app directive
move the ng-controller directive to a parent element for wherever you reference things on $scope
create a controller by using angular.module(...).controller() instead of just creating a random JavaScript function

I am using below example and it's not printing the value defined in $event
Below is my app.js
var myModule = angular.module("myModule",[])
myModule.controller("myController",function($scope){
$scope.someName = "test";
})
Below is my html
<html ng-app="myModule">
<head></head>
<body>
<div ng-controller="myController">
This is Angular JS {{ someName }}
</div>
</body>
</html>
There are no issues with your code. Make sure you have refered angularjs reference as below
DEMO
var myModule = angular.module("myModule",[])
myModule.controller("myController",function($scope){
$scope.someName = "test";
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<html ng-app="myModule">
<head></head>
<body>
<div ng-controller="myController">
This is Angular JS {{ someName }}
</div>
</body>
</html>
New to angular. Had it running fine with no controller then added a ng-controller directive to HTML markup and broke interpolation. Using Angular 1.6. What am I missing?
<head>
<script src ="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.2/angular.min.js"> </script>
</head>
<body>
<div ng-controller = "mainCtrl">
<p>Hello JS</p>
<p ng-if = "true">GM</p>
</div>
<script>
var module = angular.module("myapp" , []);
module.controller("mainCtrl", Main);
function Main(){
console.log("controller");
}
</script>
</body>
Please look at the following code:
<html lang="en" >
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-app="flexbox" >
<div id="wrapper" ng-controller="flex-ctrl as ctrl">
<div id="aside">
<p ng-repeat="item in ctrl.buttons"> {{item}} </p>
</div>
</div>
</body>
</html>
var app = angular.module("flexbox", []);
app.controller("flex-ctrl", ['$scope', function($scope) {
$scope.buttons = ['a','b', 'c'];
}]);
I expect to see three <p> items. However, it looks like ng-repeat is ignored and I see an empty page.
Do you know what is the problem?
For your convenience: http://codepen.io/CrazySynthax/pen/yVwWdo
Use this.buttons instead of $scope.buttons since you are using controller as syntax
var app = angular.module("flexbox", []);
app.controller("flex-ctrl", ['$scope', function($scope) {
this.buttons = ['a','b', 'c'];
}]);
<!DOCTYPE html>
<html>
<head>
<script data-require="angular.js#1.4.7" data-semver="1.4.7" src="https://code.angularjs.org/1.4.7/angular.js"></script>
</head>
<body ng-app='flexbox'>
<div id="wrapper" ng-controller="flex-ctrl as ctrl">
<div id="aside">
<p ng-repeat="item in ctrl.buttons"> {{item}} </p>
</div>
</div>
</body>
</html>
Since you are using controller as syntax you can change your ctrl like so:
var app = angular.module("flexbox", []);
app.controller("flex-ctrl", [function() {
var vm = this;
vm.buttons = ['a','b', 'c'];
}]);
hope it helps.
Your variable is in $scope, so you can just loop over it with:
<p ng-repeat="item in buttons"> {{item}} </p>
Instead of
<p ng-repeat="item in ctrl.buttons"> {{item}} </p>
Forked your Codepen here.
Here is my code there are two different applications in which two different controllers but the later one is not running. Why is this happening both of these are two different modules?
<!DOCTYPE html>
<html>
<head>
<title>EggHead IO</title>
<link rel="stylesheet" href="css/bootstrap.min.css">
<script src="js/lib/angular.js"></script>
<script>
var app=angular.module('ctrldemo', []);
app.controller('FirstCtrl', function($scope){
$scope.name="yashdeep",
$scope.age="21"
});
var papa=angular.module('anodemo', []);
papa.controller('anoFirstCtrl', function($scope){
$scope.name="yamini";
$scope.age="22"
});
</script>
</head>
<body>
<div ng-app="ctrldemo" ng-controller="FirstCtrl">
<input type="text" ng-model="greeting"/>
<div>
{{greeting+" "+name+" "+age}}
</div>
</div>
<div ng-app="anodemo" ng-controller="anoFirstCtrl">
<input type="text" ng-model="greeeting">
<div>
{{greeeting+" "+name+" "+age}}
</div>
</div>
</body>
</html>
If you want to run multiple angular apps, you will need to manually bootstrap the apps using angulars .bootstrap()
var app = angular.module('ctrldemo', []);
app.controller('FirstCtrl', function ($scope) {
$scope.name = "yashdeep",
$scope.age = "21"
});
angular.bootstrap(document.getElementById('ctrldemo'), ['ctrldemo']);
var papa = angular.module('anodemo', []);
papa.controller('anoFirstCtrl', function ($scope) {
$scope.name = "yamini";
$scope.age = "22"
});
angular.bootstrap(document.getElementById('anodemo'), ['anodemo']);
You will also need to remove the ng-app from the HTML
<div id="ctrldemo" ng-controller="FirstCtrl">
<input type="text" ng-model="greeting" />
<div>{{greeting+" "+name+" "+age}}</div>
</div>
<div id="anodemo" ng-controller="anoFirstCtrl">
<input type="text" ng-model="greeeting">
<div>{{greeeting+" "+name+" "+age}}</div>
</div>

Whether or not this is a good idea, I'm not too sure. I think it would be better to inject the modules into the app.
There can only be one ng-app in a page and angular can only be bootstrapped once.
In order to use separate modules you need to have one master module and inject other modules into it as dependencies
var app=angular.module('ctrldemo', ['anodemo']);
<html ng-app="ctrldemo">
Now you can use controllers, services, directives etc from either module
If you are going to do it at all the best way would be by using a directive. Which is what I did. It's called ngModule. Here is what your code would look like using it:
<!DOCTYPE html>
<html>
<head>
<script src="angular.js"></script>
<script src="angular.ng-modules.js"></script>
<script>
var moduleA = angular.module("MyModuleA", []);
moduleA.controller("MyControllerA", function($scope) {
$scope.name = "Bob A";
});
var moduleB = angular.module("MyModuleB", []);
moduleB.controller("MyControllerB", function($scope) {
$scope.name = "Steve B";
});
</script>
</head>
<body>
<div ng-modules="MyModuleA, MyModuleB">
<h1>Module A, B</h1>
<div ng-controller="MyControllerA">
{{name}}
</div>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
<div ng-module="MyModuleB">
<h1>Just Module B</h1>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
</body>
</html>
I have a simple app in which i have a single input element with a mylist model.
If mylist=1 i ng-include first.html and if mylist=2 i ng-include second.html. So far so good.
My problem is that in each html template i have a button that when clicked i want to change the value of mylist so i can navigate to the other and in order to achieve this i do:
<button ng-click="mylist=x" >switch to x</button>
but ng-click doesn't work. Why?
Here is my code:
scripts.js
var myApp = angular.module('myApp', []);
myApp.controller('MainController', function ($scope) {
$scope.mylist = 1;
});
index.html
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="https://code.angularjs.org/1.2.16/angular.js"></script>
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<input type="number" ng-model="mylist" />{{mylist}}
<br/>
<div ng-switch on="mylist">
<div ng-switch-when=1>
<ng-include src="'first.html'"></ng-include>
</div>
<div ng-switch-when=2>
<ng-include src="'second.html'"></ng-include>
</div>
</div>
</body>
</html>
first.html
<p>first</p>
<button ng-click="mylist=2" >switch to 2</button>
second.html
<p>second</p>
<button ng-click="mylist=1">switch to 1</button>
Also here is the Plunker http://plnkr.co/edit/bVATLV66kN21LC8EPeoW
ng-include creates a child scope. So you should bind to an object property instead of a primitive.
$scope.my = {
list: 1
};
