This issue is most likely due to my naivity as I am just beginning to teach myself JS and AngularJS in parallel. I have put together a simple example of what I am seeing in this plunker. Basically, my app handles an ng-repeat correctly, but as soon as I add the config method it does not replace {{menuItem.itemName}} with the value of the variable. Now, my config method is currently empty, so that may be the problem. But, I assumed I could just have a no-op method and add routes as I went, testing each one.
Here is my HTML:
<html ng-app="site">
<head>
<script src = https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.5/angular.min.js></script>
<script src ="script.js"></script>
<link href="http://fonts.googleapis.com/css?family=Great+Vibes" rel="stylesheet" type="text/css">
<title>Site</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body ng-controller='mainCtrl'>
<div id="main-container">
<div id="header">Site
</div>
<div id="side-bar">
<ul id="side-bar-menu">
<li ng-repeat="menuItem in menuItems"><span class="underline"><a ng-href={{menuItem.itemLink}}>{{menuItem.itemName}}</a></span></li>
</ul>
</div>
</div>
</body>
</html>
JS:
'use strict';
angular.module('site',[]).
controller('mainCtrl', ['$scope', function($scope) {
$scope.menuItems = [{
itemName: "Home",
itemLink: "#Home"
}];
}]);
//enabling the config breaks the output (and of course ;
//above needs to be replaced with . when config enabled)
/*config(['$routeProvider', function($routeProvider) {}]);*/

Just defined an app 'Demo' in AngularJS
'use strict';
var app = angular.module('demo', []);
app.controller('DemoCtrl', function($scope) {
$scope.obj={language_selected : {'name':'Choose a language'}};
$scope.language_list = [{'name': 'english', 'url': 'https://raw.githubusercontent.com/stevenrskelton/flag-icon/master/png/16/country-4x3/gb.png'},{'name': 'italian', 'url': 'https://raw.githubusercontent.com/stevenrskelton/flag-icon/master/png/16/country-4x3/it.png'}];
});
Now defined an HTML page correspondingly
<!DOCTYPE html>
<html lang="en" ng-app="demo">
<head>
<meta charset="utf-8">
<title>AngularJS ui-select</title>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.18/angular.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.18/angular-sanitize.js"></script>
<link rel="stylesheet" href="select.css">
</head>
<body ng-controller="DemoCtrl">
<div class="select_list" ng-class='{active:active}' ng-click="active=!active">
<span ng-style="{'background-image':'url('+obj.language_selected.url+')'}">{{obj.language_selected.name}}</span>
<ul class="options">
<li class="select_list_option" ng-repeat="language in language_list" ng-click="obj.language_selected=language" ng-style="{'background-image':'url('+language.url+')'}">{{language.name}}</li>
</ul>
</div>
</body>
</html>
EDIT: Checked the appName -> 'demo' & ng-app is demo & controller is DemoCtrl & ng-controller is DemoCtrl. It is defined appropriately.
The plunker now gives out an empty page.
Am I missing anything here ? Plunker link here: http://next.plnkr.co/edit/nXsUgM7nEsfg7jXh
You forgot to load you js code, please add
<script src="demo.js"></script>
Here is plunker http://next.plnkr.co/edit/g4yKhngP1TyJ8jLr
You are missing to add the reference to demo.js in the index.html. Add the references as follows.

I'm building a cordova app and want to use angular to build out pages a the user selects content. I'm building out in the web right now before I move to cordvoa.
<!doctype html>
<html ng-app="nanoApp">
<head>
<link rel="stylesheet" href="css/main.css">
<script src="js/angular.min.js"></script>
<script src="js/ngroute.min.js"></script>
<script src="js/angular-script.js"></script>
</head>
<body>
<div id="content" class="scroller" ng-view></div>
</body>
</html>
angular-script.js:
var nanoApp = angular.module('nanoApp',['ngRoute']);
nanoApp
.config(function($routeProvider) {
$routeProvider
.when('/', {
controller:'HomeController as homeSlides',
templateUrl:'../content/home.html'
});
});
home.html:
<div id="home" class="container paralax">
...
</div>
That's because you didn't define HomeController.
Try to create controller first
Like this
var nanoApp = angular.module('nanoApp',['ngRoute']);
nanoApp.controller("HomeController",["$scope",function($scope){
//put your code here
}]);
I'm trying to add animation when changing the content inside a my html using ng-inculde, but when ever i add ['ngAnimate'] in the declaration of the controller all of the content inside the main tag simply dissapear.
HTML:
<div ng-app="myApp">
<div ng-controller="firstCtrl">
<div id="wrapper">
<main ng-init="nav('data/table.html')">
<div ng-include="filePath">
</div>
</main>
</div>
</div>
</div>
JS:
var myApp = angular.module("myApp",['ngAnimate']);
myApp.controller ('firstCtrl', function($scope, PersonService){
$scope.users = PersonService.list();
$scope.saveUser = function () {
PersonService.save($scope.newuser);
$scope.newuser = {};
}
$scope.nav = function(path){
$scope.filePath = path;
}
})
this code wont work since im adding ['ngAnimate'] but if i'll delete it and keep the brackets empty the content will display. can someone tell me why and if its the correct way to get the animation when the content changes (table.html changes to a different file)
this is the header part incase needed:
<head lang="en">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.12/angular-sanitize.js"></script>
<script src="https://code.angularjs.org/1.2.6/angular-animate.js"></script>
<script src="js/angular.min.js"></script>
</head>
Give reference of angular-animate.min.js file in order to use 'ngAnimate' module. You have to give reference of this file after angular.min.js.
I am learning angular js right now and have hit another rut. I am trying to make my buttons change the movie ID. I know it is recognizing the click because I had it change some words in the HTML file to test it. I think it isn't talking to my JS file.
I found this during my search http://jsfiddle.net/7Sg6a/. The docs just have an expression inside the parenthesis and this example has parameters. I tried both and a few other but neither worked.
Here is my latest failed attempt. If I could get a nudge in the right direction I would be very grateful.

var movies = angular.module('movies', []);
movies.controller('movieController', function ($scope, $http) {
$http.jsonp('http://api.rottentomatoes.com/api/public/v1.0/movies/771303861.json', {
params: {
apikey: 'wq98h8vn4nfnuc3rt2293vru',
callback: 'JSON_CALLBACK'
}
})
.success(function (data) {
$scope.movies = data;
});
});
movies.click('nowShowing', function ($scope){
alert("asdasd");
});
how long until I actually get this and can stop asking stupid questions?
your .click function doesn't belong. You're using Angular like jQuery, and it's more (awesome) than that. You need to put the nowShowing function and such inside your controller:
var movies = angular.module('movies', []);
movies.controller('movieController', function ($scope, $http) {
$http.jsonp('http://api.rottentomatoes.com/api/public/v1.0/movies/771303861.json', {
params: {
apikey: 'secret',
callback: 'JSON_CALLBACK'
}
})
.success(function (data) {
$scope.movies = data;
});
$scope.nowShowing = function(){
//whatever is in here will execute when a user interacts with an element with the ng-click="" directive
}
});
Also, I would highly recommend you create a service for your http requests to your api. You are creating a tightly coupled app with your current approach.
movies.factory('moviedata',function($http){
return
$http.jsonp('http://api.rottentomatoes.com/api/public/v1.0/movies/771303861.json', {
params: {
apikey: 'secret',
callback: 'JSON_CALLBACK'
}
})
})
then 'inject' it in your controller like so:
movies.controller('movieCtrl',function($scope, moviedata){
//resolve returned promise
moviedata.success(function(data){
$scope.data = data;
});
$scope.nowShowing = function($log){
//whatever is in here will execute when a user interacts with an element with the ng-click="" directive
$log.info("nowShowing method fired");
}
})
I have angularjs application and <span> in it. I try to hide it with ng-hide directive, but:
<span ng-hide="hideSpan">
And
// controller code here
....
$scope.hideSpan = true;
....
Doesn't work, it's ignoring. And if i make:
// controller code here
....
$scope.$apply(function(){$scope.hideSpan = true});
....
I get error: $apply already in progress.
How can i correctly use ng-hide/ng-show in this way?
Thank you.
You should be able to directly control the hide/show functions from your controller just as you show. The following is working example using a button to trigger toggling of hide show.
<!DOCTYPE html>
<html>
<head>
<script data-require="angular.js#1.1.5" data-semver="1.1.5" src="http://code.angularjs.org/1.1.5/angular.min.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-app="myapp" ng-controller="mycontroller">
<span ng-hide="hideSpan">Some Content to hide</span>
<button ng-click="toggleHide()"/>Toggle Hide</button>
</body>
</html>
And the script.
angular.module('myapp', []).controller('mycontroller', function($scope){
$scope.hideSpan = true;
$scope.toggleHide = function(){
if($scope.hideSpan === true){
$scope.hideSpan = false;
}
else{
$scope.hideSpan = true;
}
}
});
I've created a simple plunker to show this in action at http://plnkr.co/edit/50SYs0Nys7TWmJS2hUBt?p=preview.
As far as why the $apply is causing an error, this is to be expected as direct scope (provided by the $scopeProvider) variable operations are already watching for change and wrapped into a default apply of sorts in core angular so any change will be automatically applied to the other bindings of that variable.
you can just change the hideSpan value in ng-click, save few lines. cheers
