Here is my code, Actually when I click on function but not showing alert and not getting error in console. So please tell me how to do.
HTML Code
<li class="has-megamenu" ng-click="homepage()" ><a ><span >Home</span></a>
</li>
app.js
app.controller('myController', function($scope){
$scope.homepage = function(){
alert('hi');
}});
There can be two reasons
1- Not using ng-app directive in the root element of your application.
2- You have not defined ng-controller properly.
Please follow following working code.
<html>
<head>
<link rel="stylesheet" href="style.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.5/angular.js"></script>
<script>
var app = angular.module('app', []);
app.controller('myController', function($scope) {
$scope.homepage = function() {
alert('hi');
}
});
</script>
</head>
<body ng-app="app">
<div ng-controller="myController">
<ul>
<li class="has-megamenu" ng-click="homepage()"><a><span >Home</span></a>
</li>
</ul>
</div>
</body>
</html>
First You have to add ng-app = "app"
Second You have to add ng-controller = "myController"
Final
Please check the updated code:
var app = angular.module("app", []);
app.controller('myController', function($scope){
$scope.homepage = function(){
alert('hi');
}});
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>
<body ng-app = "app">
<div ng-controller = "myController">
<li class="has-megamenu" ng-click="homepage()" ><a ><span >Home</span></a>
</li>
<div>
</body>
</html>

I am new to angularjs and I want to know why it isn't working.
The code has a flaw and am not sure about the same.
Thinking from java perspective,httpController defined has nested function defined inside.
Here it is my code
index.html
<!DOCTYPE html>
<html >
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body>
<div ng-app="myapp" ng-controller="HelloController">
<h2>{{message}}</h2>
</div>
<div ng-app="httpService" ng-controller="httpController">
<div>FirstName:{{user.name}}</div>
</div>
</body>
</html>
Script.js
var app = angular.module("myapp", []);
app.controller("HelloController", function($scope) {
$scope.message = "Hello, AngularJS";
});
var httpApp=angular.module("httpService",[]);
httpApp.controller("httpController",function($scope,$http){
var onUserComplete=function(response){
$scope.user=""response.data"";
}
$http.get("https://api.github.com/users/rob").then(onUserComplete);
}
);
Only one ng-app will be automatically bootstrapped on your page. That's why if you remove the first ngApp directive, the second one will work.
var httpApp = angular.module("httpService", []);
httpApp.controller("httpController", function($scope, $http) {
var onUserComplete = function(response) {
$scope.user = response.data;
}
$http.get("https://api.github.com/users/rob").then(onUserComplete);
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<div ng-app="httpService" ng-controller="httpController">
<div>FirstName: {{user.name}}</div>
</div>
NOTE: You have a typo in your callback, remove ""s around your response.data. Also, since you are using Angular 1.5.6, you don't need to specify dependencies/inject your $http service to make your code work.

This link is working fine...just try it out
Do not use ng-app more than once in your program...Your code would not work
I am having troubles with using ng-click. I have added ng-click directive to the button. It does not trigger the function associated with ng-click. In Angular Batarang tool, it says the functions are undefined.
I tried the problem in Plunker.It does work. And also If i hard code the file path it works.
index.html code
<!DOCTYPE html>
<HTML ng-app="myEventApp">
<head>
<meta charset="UTF-8">
</head>
<body>
<h1 ng-controller="HelloWorldController">{{ helloMessage }}</h1>
<div ng-controller="EventDetail">
</div>
<div ng-include="" src="fileName"></div>
<!--<ng-include src="fileName"></ng-include>-->
<!--<div ng-include="" src="'template/testing10000.html'"></div>-->
<button ng-click=incrementCounter()>Next</button>
<button ng-click=decrementCounter()>Back</button>
<script
src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.0/angular.js"></script>
<script src="js/app.js"> </script>
</body>
</HTML>
app.js code
var app = angular.module("myEventApp", []);
app.controller('HelloWorldController', ['$scope', function($scope){
$scope.helloMessage = "Book Viewer";
}]);
app.controller('EventDetail', ['$scope', function($scope){
$scope.counter = 0;
$scope.fileName = 'template/testing1000'+$scope.counter+'.html';
$scope.incrementCounter = function(){
$scope.counter++;
$scope.fileName = 'template/testing1000'+$scope.counter+'.html';
console.log($scope.counter);
}
$scope.decrementCounter = function(){
$scope.counter--;
$scope.fileName = 'template/testing1000'+$scope.counter+'.html';
console.log($scope.counter);
}
}]);
You declared the functions inside the EventDetail controller, but you have the buttons outside of the controller container in the html.
<div ng-controller="EventDetail">
<div ng-include="" src="fileName"></div>
<button ng-click="incrementCounter()">Next</button>
<button ng-click="decrementCounter()">Back</button>
</div>
Im new to angular and js
please help me getting json key and bind to ng-model
Following is my code
<div ng-app="myApp" ng-controller="customersCtrl">
<ul>
<li ng-model="table.macid"></li>
</ul>
and my js is
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
$scope.table={}
$http.get("test.json")
.success(function(response) {
$scope.names = response
$scope.table.macid= Object.keys($scope.names.day.weekday.Monday.mac_id)
console.log($scope.table)
});
});
this is my plunker link http://plnkr.co/edit/6CoOAp0X8FZw1JODXSHT?p=preview
Any help is appreciated, Thanks in advance
You are confusing ng-model with ng-bind:
<div ng-app="myApp" ng-controller="customersCtrl">
<ul>
<li ng-bind="table.macid"></li>
</ul>
See updated plunker
In case you need to iterate over the collection, use ng-repeat. See zszep answer for that.
You can dump it out on your html like this:
<li ng-model="table.macid"></li>{{table.macid}}
It should work, it did for me. You may think you see it because the tag is in an < li > element. What are you expecting that to do?
Use ng-repeat in the li tag like this plunker:
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="customersCtrl">
<ul>
<li ng-repeat="macid in table.macid">{{macid}}</li>
</ul>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
$scope.table={}
$http.get("test.json")
.success(function(response) {
$scope.names = response
$scope.table.macid= Object.keys($scope.names.day.weekday.Monday.mac_id)
});console.log($scope.table)
});
</script>
</body>
</html>
I had already declared my app and controller in separate file and below is how i am loading my controller html DOM but it is not showing that message. Can someone please guide how to achieve this.
HTML:
<div id="bnProblemList">
<div ng-controller="problemListCtrl" data-ng-init="init()">
<div ng-view="">this is my message = {{message}}</div>
</div>
</div>
JS:
html = $j('#bnProblemList').html();
$compile(html)(scope);
Please let me know how to inject or load ng-controller html dynamically.
Your controller declaration is wrong. You should do it like this:
var myApp = angular.module('myApp',[]);
myApp.controller('problemListCtrl', ['$scope',
function($scope) {
$scope.message = "This is my message :-)";
}
]);
A proper way is to declare your Controller into an anonymous function, and add it to a module. Then, you have to set your ngApp.
Controller.js
Here, we will declare our controller, and create an app module. Then, we will declare ctrl as our controller into our app module.
(function(){
function Controller($scope) {
$scope.name = 'toto';
}
angular
.module('app', [])
.controller('ctrl', Controller);
})();
HTML
<body ng-app='app' ng-controller="ctrl">
<p>My name is {{name}}</p>
</body>
And don't forget to include your script tag :
<script src="controller.js"></script>
You can try Like below Example:-
Html Page:
<!DOCTYPE html>
<html ng-app="MyApp">
<head>
<title> Controller</title>
<script src="../Js/angular.min.js"></script>
<script src="../Js/Controller.js"></script>
</head>
<body>
<div ng-controller="MyFirstController">
{{ Msg }}
</div>
</body>
</html>
ControllerJs Page:
var MyApp=angular.module("MyApp",[]);
MyApp.controller("MyFirstController",function($scope){
$scope.Msg="Hello First Conroller";
})
i was able to load/ inject controller dynamically by the help of below code
<div id="bn" ng-controller="myCtrl as vm">
<div ui-view=''></div>
</div>
<script>
angular.element(document).injector().invoke(function($compile, $state) {
$state.go('myCtrl');
var scope = angular.element($j("#bn")).scope();
$compile($j("#bn"))(scope);
});
</script>
Hi I am having trouble with this tutorial. I copied over the code but for some reason it is not working.
This is the html code
<!DOCTYPE html>
<html ng-app>
<head>
<title>Simple app</title>
<script
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.6/angular.js">
</script>
</head>
<body>
<div ng-app="myApp">
<div ng-controller = "MyController">
<h1>{{ person }}</h1>
and their name:
<h2> {{person.name}}</h2>
</div>
</div>
<script type="text/javascript" src="app.js"></script>
</body>
</html>
and here is the JS
var app = angular.module('app', []);
app.controller('MyController', function($scope) {
$scope.person = {
name: "Ari Lerner"
};
});
It doesn't look like the AngularJS code is being recognized. Any ideas?
Your app name in the module definition:
var app = angular.module('app', []);
doesn't match the one you reference in your dom:
<div ng-app="myApp">
Change your module definition to:
var app = angular.module('myApp', []);
