I'm testing the cookies of angularjs. Am I wondering why it's returning undefined in the console? When I set or save value using the $cookieStore.put() is working then when in getting the value from the cookie it's returning undefined.

<script>
angular.module('app', ['ngCookies']).controller('MyController', ['$scope','$cookieStore', function($scope, $cookieStore) {
$scope.WriteCookie = function() {
$cookieStore.put('visited', $scope.yes);
console.log($cookieStore.get('visited'));
}
$scope.ReadCookie = function() {
$cookieStore.get('visited');
console.log($cookieStore.get('visited'));
}
}]);
</script>
</head>
<body ng-app="app">
<form>
<div ng-controller="MyController">
<input type="button" value="Write Cookie" ng-click="WriteCookie()" />
<input type="text" ng-model="yes" />
<input type="button" value="Read Cookie" ng-click="ReadCookie()" />
<input type="text" ng-model="cookie" />
</div>
</form>
</body>
</html>
Try like this :
update cookie version 1.6.6 and use $cookies instead of $cookieStore
angular.module('myApp', ['ngCookies'])
.controller('myController', ['$cookies', function($cookies) {
$cookies.put('myFavorite', 'oatmeal');
var favoriteCookie = $cookies.get('myFavorite');
console.log('favoriteCookie', favoriteCookie);
}]);
I tested your code two ways. Opening it as file and from server. In the first case I get 'undefined' whereas in second case it reads the cookie as expected. I did some digging and looks like some browser including Chrome does not allow setting cookies for a page opened as a file. More info ...

I tried by using
It results in the output as
<h1> Welcome</h1>
I tried by replacing ng-bind-html is not woking and throws an error.
<script>
angular.module('form', []).controller('formcontroller', ['$scope', function($scope) {
$scope.hello="<h1> Welcome</h1>";
}]);
</script>
Error: $sce:unsafe Require a safe/trusted value Attempting to use an
unsafe value in a safe context.
Please explain.
If you include the angular-sanitize script, inputs are sanitized by parsing the HTML into tokens
var miAp = angular.module('miAp', ['ngSanitize']);
miAp.controller('demoController', function($scope) {
$scope.bar = "<h1> Welcome</h1>";
});
<html>
<head>
<meta charset="utf-8">
<title>ngBind</title>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.9/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.1/angular-sanitize.min.js" type="text/javascript"></script>
<script src="cookies.js"></script>
</head>
<body ng-app="miAp" ng-controller="demoController">
<div ng-bind-html="bar"></div>
</body>
</html>
You can install and include ngSanitize.
This should fix the error.
When you use ng-bind-html to bind html string , that html need to be marked safe to prevent prevent XSS and other security issues . This is checked by Angular's Strict Contextual Escaping (SCE) mode that enabled by default .
You can see more in this link : https://docs.angularjs.org/error/$sce/unsafe .
To resolve this problem, you can view this issue :
With ng-bind-html-unsafe removed, how do I inject HTML?
Hope this help ! Thanks
Try This
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.9/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.1/angular-sanitize.min.js" type="text/javascript"></script>
var App = angular.module('sanitize', ['ngSanitize']);
App.controller('demoController', function($scope) {
$scope.bar = "<h1> Welcome</h1>";
});
<h1 data-ng-bind="hello"></h1>
This is a problem that can be easily done by declaring a scope function but I was wondering if there is a better way to make this easier
The code is:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<link rel="stylesheet" type="text/css" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
</head>
<body ng-controller="myCtrl">
<input type="checkbox" ng-model="activate" id="activate"> ACTIVATE <br />
<input type="text" ng-model="first" ng-disabled="!activate">
<input type="text" ng-model="second" ng-disabled="!activate">
<!-- <span id="clickMe">Click Me!</span> -->
<script type="text/javascript">
app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $timeout){
});
</script>
</body>
</html>
So this is the case. The other two fields will be enabled if the checkbox is checked and true and will be disabled if the checkbox is unchecked. What I want is, to make the fields go null or blank automatically upon disabling.
Here is an example: http://plnkr.co/edit/2EPuhRiR9OncV8z7q018?p=preview
Ignoring the fact that it is not a good practice to put too much logic directly in the view, a technical solution would be:
<input type="checkbox" ng-model="activate" id="activate" ng-change="sameAsAbove(first, second); value = null"> ACTIVATE <br />
<input type="text" ng-model="value.first" ng-disabled="!activate">
<input type="text" ng-model="value.second" ng-disabled="!activate">
I'm following this video tutorial and messed something up in the haste.. The problem is that I got rid of all the errors I made, but it still doesn't work as expected. The search form box doesn't display.

Any help would be appreciated
The problem is that you are redefinig the module in the controller and factory code:
var app = angular.module("githubViewer",[]);
Instead of gettingthe created module:
var app = angular.module("githubViewer");
A module should be created once, then retrieve and add the controller, config, factory, etc...
Here some help.
Basically you all js file has wrong IIFE pattern.wrong
It should be
})();
instead of
}());
Also there are typos. In index.html:
<script scr="app.js"></script>
Must be:
<script src="app.js"></script>
And in MainController.js. This code:
app.controller("MainControler", MainController);
Must be changed to:
app.controller("MainController", MainController);
You are misunderstanding how to implement a module and a controller. In both MainController.js and app.js, you have the line:
var app = angular.module("githubViewer", ["ngRoute"]);
angular.module actually creates a new module. You are effectively trying to create two modules with the same name, which isn't allowed.
The pattern to follow is
var app = angular.module(...)
app.config(...)
var controller = app.controller("MainController", ["$scope", function() {
]]);
If you really want the MainController code to be in a separate file, create a function:
function createMainController(app) {
app.contoller("MainController", ...)
}
Here is a simple code, where I tried to implement what I'm talking about:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Example - example-example32-production</title>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.0-beta.0/angular.min.js"></script>
</head>
<body ng-app="app">
<div ng-controller="AppController">
<form name='AlertForm' ng-init="action = 'AlertForm.$valid && print(text)'">
Input: <input type="text" ng-model="text" ng-keyup='$event.keyCode == 13 && {{action}}' /><br />
<input type="button" ng-click="{{ action }}" value="Alert" />
</form>
</div>
<script>
angular.module('app', [])
.controller('AppController', ['$scope', function($scope) {
$scope.print = function(msg) {
alert(msg);
};
}]);
</script>
</body>

There is a form with a single input and a button. If you press the button or press enter, while staying in the input, it will alert you with content of the input.
I've tried to use ng-init and Angular templating for caching the print(text) expression, to avoid redundancy, but it doesn't work.
Is there any other ways, to do that without touching controller?
Im basic developer , just wanted to pass hidden values from my html page in a json array . Following is my code :-
Index.html
<!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 src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>
<script src="app.js"></script>
</head>
<body>
<div ng-controller="WorkingCtrl">
<h1 ng-bind="vm.heading"></h1>
<form name="myForm" novalidate>
<b> Text: </b>
<input ng-model="form.text" required /><br>
<button ng-click="submitForm()" bng-disabled="myForm.$invalid">Click Me!</button>
</form>
<p ng-bind="showValues"></p>
</div>
</body>
</html>
app.js
var app = angular.module('myApp');
app.controller('WorkingCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.form = {};
$scope.submitForm = function () {
$scope.showValues = JSON.stringify($scope.form);
}
}]);
Now , the value from ng-model="form.text" successfully returns the result as for unhidden input types
{ "text":"What_ever_text" }
but how to send a defined value in array, consisting of hidden input type like :-
<input value="99999" type="hidden" ng-model="form.userid" required />
So , wanted desired output like :-
{ "text":"What_ever_text" , "userid":"99999" }
any solution ?
Note :- The input type should be hidden or any other easier method appreciated. Thanks in advance.
hidden input fields also works same as normal fields only.
see the below code
var app = angular.module('myApp', []);
app.controller('WorkingCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.form = {
text: "some test",
userid: '12312312312'
};
$scope.submitForm = function () {
$scope.showValues = JSON.stringify($scope.form);
}
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="WorkingCtrl">
<h1 ng-bind="vm.heading"></h1>
<form name="myForm" ng-submit="submitForm()" novalidate>Text:
<input ng-model="form.text" required />
<br/>
<input type="hidden" ng-model="form.userid" required />
<button bng-disabled="myForm.$invalid">Click Me!</button>
</form>
<p ng-bind="showValues"></p>
</div>
</div>
