AngularJS error: fnPtr is not a function - javascript

I'm trying to write a sample AngularJS, and SpringMVC project. The spring methods works fine, but I have a problem with declaraton of function in my site controller. My app should return a word from text input, but when I click the button, I've got this error:
[13:23:58.900] "Error: fnPtr is not a function

</div>
<ul>
<li ng-repeat="name in names">{{name}}</li>
</ul>
</body>
</html>
And controler.js:
function theNamer ($scope,$http){
$scope.myName='aa';
$scope.fetchList=new function()
{
$http.get('ca/list.json').success(function(thList){
$scope.names = thList;
});
}
$scope.send=new function()
{
$http.post('ca/set/3').success(function(){
$scope.fetchList;
});
}
$scope.fetchList;
}
var Apken = angular.module('Apken',[]);
Apken.controller('theNamer', theNamer);
I've noticed, that must be a some kind of problem with function declaration in the ng-click value. On site startup controler.js works fine, but it crashes, when I click the button.

Just wanted to add for anybody receiving this error, it can also be seen if you, like me, make the n00b mistake of creating a variable with the same name as function (the function being called from ng-click:
$scope.addTask = {};
$scope.addTask = function() {};

I have tested your code. Using AngularJS 1.0.7, the error disappears when you replace
$scope.send = new function() {
with
$scope.send = function () {
and same applies to fetchList.
I guess you mixed the two syntaxes function(*args*) { *body* } and new Function(*args*, *body*). Check on MDN: Function.
You have also to change your code in order to get your fetchList properly called:
function theNamer($scope, $http) {
$scope.myName = 'aa';
$scope.fetchList = function() {
$http.get('ca/list.json').success(function(thList) {
$scope.names = thList;
});
};
$scope.send = function() {
$http.post('ca/set/3').success(function() {
$scope.fetchList();
});
};
$scope.fetchList();
}

You should change your '' to this:
<body ng-controller="MainCtrl" ng-model="demo" ng-change="comp();">
If you check the url from the first line of the error log: https://docs.angularjs.org/error/$compile/ctreq?p0=ngModel&p1=ngChange. The problem is explained:
Controller 'ngModel', required by directive 'ngChange', can't be
found! Description This error occurs when HTML compiler tries to
process a directive that specifies the require option in a directive
definition, but the required directive controller is not present on
the current DOM element (or its ancestor element, if ^ was specified).
To resolve this error ensure that there is no typo in the required
controller name and that the required directive controller is present
on the current element.
The directive 'ng-change' require a 'ng-model' to work properly, that is why you are getting an compile error.
Now your second question, "Why onclick doesn't work ?". You should never manipulate the DOM from the controller, if you have to do that use a directive. When you call "scopecomp()" from the ng-click that method is invoked from "within" the angular engine, it will fire an digest cycle which will process the "html" (it's more than that, I'm trying to keep it simple) and print what you expect, but when you add "{{demo}}" directly to the DOM, that variable will not be processed.
There is no need to change the DOM manually to do what you are looking for, check the snippet below. I simulated your "database request" with a timeout function.
angular.module("app", [])
.controller("MainController", MainController);
MainController.$injector = ['$timeout'];
function MainController($timeout) {
var vm = this;
vm.post = null;
function loadStuff() {
$timeout(function() {
vm.post = {
title: "Post Title",
content: "Post Content"
};
}, 1000);
}
loadStuff();
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="MainController as main">
<p ng-hide="main.post">Loading...</p>
<h3>{{main.post.title}}</h3>
<p>{{main.post.content}}</p>
</div>
$FirebaseJS.Run(function(){
$scope.$apply(function(){
$scope.obj = globalOBJ;
});
});
Finally I got it.

Execise angularJS windows alert not woring

i've a simple problem, i've copied and pasted some code and i'd like to show an alert with a value inside it. I'm just learning angular and the fuction works (i've places a console log inside it and it is executed), but the window.alert doesn't appear.
I've read this tutorial and tried changing the name of variable but it's still not working. In the online tutorial of angual everything is going fine so where is my mistake?
Here is the page code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" charset="utf-8" src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.5/angular.min.js"></script>
<script type="text/javascript" charset="utf-8" src="greetings.js"></script>
</head>
<body>
<h1>Greetings</h1>
<div ng-app="greetings" ng-controller="GreetingsController as greeting">
<b>Greetings:</b>
<div>
Name: <input type="text" min="0" ng-model="greeting.name" required >
</div>
<div>
FamilyName: <input type="text" ng-model="greeting.familyName" required >
<select
data-ng-options="c for c in greeting.tipi" data-ng-model="greeting.selectedOption">
<!--<option ng-repeat="c in greeting.tipi">{{c}}</option>-->
</select>
</div>
<div>
<b>Greeting:</b>
<span>
{{greeting.total(greeting.selectedOption)}} {{greeting.name}} {{greeting.familyName}}
<button class="btn" ng-click="invoice.greet(greeting.selectedOption)">Greet</button>
<br/>
</span>
</div>
</div>
</body>
</html>
Here is the controller code greetings.js:
angular.module('greetings', [])
.controller('GreetingsController', function() {
this.name = "Name";
this.familyName = "FamilyName";
this.tipi = ["Hello", "Good Morning", "Good Afternoon", "Good evening"];
this.selectedOption = this.tipi[0];
this.total = function total(outGree) {
console.log(outGree);
return outGree;
};
this.greet = function greet(outGree) {
console.log(outGree);
$window.alert(outGree);
};
});
To use an Angular service, you add it as a dependency for the component (controller, service, filter or directive) that depends on the service.
And $window is a service.
you should add the parameter or the dependency $window to use this service.
angular.module('greetings', [])
.controller('GreetingsController', ['$window', function($window) {
this.name = "Name";
this.familyName = "FamilyName";
this.tipi = ["Hello", "Good Morning", "Good Afternoon", "Good evening"];
this.selectedOption = this.tipi[0];
this.total = function total(outGree) {
console.log(outGree);
return outGree;
};
this.greet = function greet(outGree) {
console.log(outGree);
$window.alert(outGree);
};
}]);
You need to include $window in your dependencies, or else your controller reads it as undefined.
Try the following:
angular.module('greetings', [])
.controller('GreetingsController', function($window) {
//Rest of your code
this.greet = function greet(outGree) {
console.log(outGree);
$window.alert(outGree);
};
});
I added $window as a parameter to the function of your controller.
the problem was in the html code:
<button class="btn" ng-click="invoice.greet(greeting.selectedOption)">Greet</button>
should have been:
<button class="btn" ng-click="greeting.greet(greeting.selectedOption)">Greet</button>

Using AngularJS on Safari

I have a problem using AngularJS on Safari running on Windows 7.
Problem appears on line 11413 in angular.js
function consoleLog(type) {
var console = $window.console || {},
logFn = console[type] || console.log || noop,
hasApply = false;
// Note: reading logFn.apply throws an error in IE11 in IE8 document mode.
// The reason behind this is that console.log has type "object" in IE8...
try {
hasApply = !!logFn.apply;
} catch (e) {}
if (hasApply) {
return function() {
var args = [];
forEach(arguments, function(arg) {
args.push(formatError(arg));
});
return logFn.apply(console, args); <------------- HERE PROBLEM APPEARS
};
}
Error: angular.js:11413setting a property that has only a getter
Can't find any solution to that in google. Does anybody know how to solve this? Using latest AngularJS v1.3.3
Here is the most simple code causing error.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="angular-route.min.js"></script>
</head>
<script>
var g_app = angular.module('cc_app', ['ngRoute']);
g_app.controller('navigation_controller', ['$scope', function($scope) {
$scope.templates =
[ { name: 'template1.html', url: 'template1.html'},
{ name: 'template2.html', url: 'template2.html'} ];
$scope.template = $scope.templates[0];
}]);
</script>
<body ng-app="cc_app" ng-controller="navigation_controller">
<select ng-model="template" ng-options="t.name for t in templates">
<option value="">(blank)</option>
</select>
url of the template: <tt>{{template.url}}</tt>
<hr/>
<div class="slide-animate-container">
<div class="slide-animate" ng-include="template.url"></div>
</div>
</body>
</html>
example is taken from https://docs.angularjs.org/api/ng/directive/ngInclude
It works fine on Chrome, but causes mentioned error on Safari.
BTW: Error is caused by ng-include.
UPDATE
It works as soon as I remove jquery.
Fixed by changing ordering of script includes. Looks like a conflict.

angularjs, Scope not updating across functions - with ngTouch

I have a controller with such:
$scope.myVar = 0;
$scope.back = function () {
$scope.myVar--;
};
$scope.next = function () {
$scope.myVar++;
};
If next() (with ngClick) is called 3 times, we get:
//1
//2
//3
but if back() (with ngSwipeLeft) is called it returns
//-1
when I'm obviously expecting
//2
What am I missing here?
update: including ngTouch details - this seems to be the problem.. ngTouch is included.
When I watch the myVar value - its like it exists twice - one with the ngSwipeLeft call, and one with the ngClick call
Your snippet looks fine to me. You need to provide more code, error might be somewhere else. Look at the code below.
<!doctype html>
<html ng-app="myapp">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.12/angular.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.20/angular-touch.min.js"></script>
<script>
var app = angular.module('myapp',['ngTouch']);
var controller = app.controller('mycontroller', ['$scope',function($scope){
$scope.myVar = 0;
$scope.back = function () {
$scope.myVar--;
};
$scope.next = function () {
$scope.myVar++;
};
}]);
</script>
</head>
<body ng-controller="mycontroller">
<div>
<h1>MyVar: {{myVar}}!</h1>
<input type="button" value="back" ng-click="back()"/>
<input type="button" value="next" ng-click="next()"/>
</div>
</body>
</html>
Ok, so I've figured out my problem - I wasn't providing enough detail in the question - but if someone runs into something similar in the future, heres what was going on:
I was declaring my controller with ng-controller="myCtrl" in the templates, but also using routing, where I declared my controller like:
$routeProvider.when('/', {
templateUrl: 'myUrl.html',
controller: 'myCtrl'
});
This was instantiating the controller twice, and obviously causing problems (although that seemed to the only one to surface for now).
Removing the controller definition from the routing or the view did the trick.
need to see your html not sure about your problem, here is a sample working code,
<div ng-app="myapp">
<div ng-controller="IncDecController">
<span>current value is {{myVar}}</span>
<img src="https://angularjs.org/img/AngularJS-large.png" ng-swipe-left="back()"></img>
<button ng-click="next()">next</button>
</div>
</div>
script:
angular.module('myapp', ['ngTouch'])
.controller('IncDecController', ['$scope', function ($scope) {
$scope.myVar = 0;
$scope.back = function () {
$scope.myVar--;
};
$scope.next = function () {
$scope.myVar++;
};
}])

Angular JS : Controller properties not shown in html

I'm new to Angular JS. Sorry for this simple question.
I have learnt something from this tutorial: http://courseware.codeschool.com/shaping-up-with-angular-js/Slides/level01-05.pdf
And I have tried an example. This is not working. http://jsfiddle.net/89wfv/1/
HTML:
<html ng-app="main">
<body>
<div ng-controller="con">
<div>{{con.desc}}</div>
<input type='button' ng-click='getDesc();' value='Get name' />
</div>
</body>
</html>
Script
(function() {
var app = angular.module("main", []);
app.controller("con", function() {
this.desc = "test description";
this.getDesc = function() {
alert(this.desc);
}
});
})();
Problem is showing description in div and alert description by click.
Thanks in advance.
you forgot controller as something
<div ng-controller="con as ctrl">
<div>{{ctrl.desc}}</div>
<input type='button' ng-click='ctrl.getDesc();' value='Get name' />
</div>
take a look at the guide instead :
https://docs.angularjs.org/guide/controller
works:
http://jsfiddle.net/pYh89/
you didnt load angular correctly and add several syntax errors.
var app = angular.module("main", []);
app.controller("con", function () {
this.name = 'foo';
this.getName = function () {
alert("foo");
};
});
Angular JS is missing in your code please include it after downloading it.
<script src="angular.js"></script>
You can also use online version.
You forgot different things:
Here's a corrected JSfiddle:
http://jsfiddle.net/89wfv/2/
You have to:
Use $scope instead of this to reference to the data that is to be bound to the view, eg:
app.controller("con", function($scope) {
$scope.name = 'vasu';
$scope.getName = function() {
alert();
}
});
Put the script tag in Head
Not use the html tag, that could be overwritten by JSfiddle:
Do rather something like this:
<div ng-app="main">
<div ng-controller="con">
</div>
</div>
