My html file look like this
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"> </script>
<script src ="ang_script.js"> </script>
</head>
<body>
<div ng-app id="bootangular" ng-controller="firstcontroller">
<button ng-click="alertfunction()"> click me </button>
</div>
</body>
</html>
and the script file is as follows
var app = angular.module("firstModule",[])
app.controller("firstcontroller",['$scope',function($scope)
{
$scope.alertfunction=function()
{
alert("Done");
};
}])
This is throwing an error which takes me to this page https://docs.angularjs.org/error/ng/areq?p0=firstcontroller&p1=not%20a%20function,%20got%20undefined
which I am not able to understand
You're not defining the ng-app correctly. Please update your HTML with below code
<div data-ng-app="firstModule" id="bootangular" data-ng-controller="firstcontroller">
</div>
And your controller code then work. I don't see any error in your controller's code.

I am starting to learn AngularJS and wanted to try building a simple calculator app, however, whenever I name the ng-app in my html-file, AngularJS stops working.
I tried building a controller, but seem to be doing something wrong when calling it or putting it to use.
I tried putting the files in the XAMPP webfolder because I thought it might not load from my hard drive, but to no avail.
(please disregard all the half-finished rest, right now I just want to get the controller working)
Here is the html:
<!DOCTYPE html>
<html>
<head>
<title>Calculator</title>
</head>
<body ng-app="calculatorApp">
<div ng-controller="mainCtrl">
<input type="number" ng-model="first" autofocus>
<input type="number" ng-model="second">
<br>
<button onClick="defineOperator('+')">+</button>
<button onClick="defineOperator('-')">-</button>
<button onClick="test()">TEST</button>
<br>
<div>
{{first}}
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"</script>
<script src="http://localhost/calculator/scripts/app.js" type="text/javascript"></script>
</body>
</html>
And the js:
angular.module('calculatorApp', [])
.controller('mainCtrl', function($scope){
$scope.defineOperator = function(choice) {
switch (operator) {
case +:
return first + second;
break;
default:
}
};
$scope.testOperator = function(click) {
alert("You chose " + operator);
};
});
Any help would be greatly appreciated.
angular.module('calculatorApp', [])
.controller('mainCtrl', function($scope){
$scope.first="hello";
});
<!DOCTYPE html>
<html>
<head>
<title>Calculator</title>
</head>
<body ng-app="calculatorApp">
<div ng-controller="mainCtrl">
<div>
{{first}}
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
</body>
</html>
Have a look at this. One thing you have not closed the tag in which angular is defined.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"</script>
You forgot to put > in above line.
Replace it with
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
You forgot to end the script tag with >
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"</script>
if you want to change the app-name in html page you should also change the app name in the js file :
angular.module('calculatorApp', [])
I know this question has been asked a bunch of times before, I read through the answers, tried the offered solutions, but I'm still getting the error and I'm not sure why. I stripped my application down to a simple hello world to try and figure out why its happening.

<!--template/helloWorld.template.html -->
<div>
<h1>hello, is it me you're looking for</h1>
</div>
if you are providing the link to the template file you should use templateUrl not template.
If you want to use template you have to write
"template":"<div>...</div>"
Change from template to templateUrl
`template:`template/helloWorld.template.html`
to
templateUrl :template/helloWorld.template.html
I have the following angular sample app:

All I'm trying to achieve is to dynamically load a controller from some html string which resides in the same page.
However, I need some help, as this current setup doesn't seem to work.
I'm copying my code exactly from an egghead.io tutorial but it isn't working. The angular expression isn't posting to the view properly (it posts with the {{}} rather than evaluating). It works if I remove ng-controller from the <body> and the value "app" from ng-app in the <html> so I can't figure out where to pinpont the problem. I've tried moving the script for the angular module/controller all over the html page (header, bottom of page, etc.) and no luck.
As a side question I'm wondering if Stackoverflow is the proper place to post this. Supposedly you're not supposed to use the 'code-review' tag and reviews of "other-wise working code" belongs on codereview.stack. My code is working sooo...
<!DOCTYPE html>

angular.module("app", [])
.controller(FirstCtrl, function FirstCtrl()[
var first = this;
first.greeting = "First";
])
</script>
</head>
<body ng-controller="FirstCtrl as first">
<input type="text" ng-model="first.greeting"/>
<div ng-class="first.greeting">
{{first.greeting}} {{World}}
</div>
</body>

I made a slight change to your code.
The Controller name needed double qoutes around it see "FirstCtrl" also you had a missing square bracket and closing bracket. Copy and past the above code it should work.
It works for me. :)
Your copying went wrong somewhere , controller name should be a string
Change:
.controller(FirstCtrl...
to
.controller('FirstCtrl'...
You should have seen errors thrown in console to give you clues about this
I have a few partial templates where the location is changed based on user actions via ng-click:
<div ng-include="contentUrl"></div>
<button ng-click="contentUrl = '../partials/testScriptForm.html'">Add Test Script</button>
This works great unless I the button above is inside of the partial itself, so if testScriptForm.html has a button:
<button ng-click="contentUrl = '../partials/testScriptCase.html'">Add Test Case</button>
Then nothing happens.
This seems due to ng-include getting a new (inherited but not shared?) scope.
What I can't figure is how to get the included template (partial) to change its own location.
I did try a function to change the $scope.$parent.contentUrl, it does seem to change but not "propagate" the changes.
In coffeescript:
$scope.changeParentLocation = (location) ->
$scope.$parent.contentUrl = location
Also tried to $scope.$apply() and $scope.$parent.$apply() in there and get the error:
Error: [$rootScope:inprog]
http://errors.angularjs.org/1.2.0rc1/$rootScope/inprog?p0=%24apply
Maybe I'm just mis-using includes...
Escape the isolated scope with "dotted model" reference:

function Ctrl($scope) {

$scope.tpl.contentUrl = '/partials/testScriptForm.html';
