@ngdoc error
@name ng:btstrpd
@fullName App Already Bootstrapped with this Element
@description
Occurs when calling {@link angular.bootstrap} on an element that has already been bootstrapped.
This usually happens when you accidentally use both `ng-app` and `angular.bootstrap` to bootstrap an
application.
```
<html>
...
<body ng-app="myApp">
<script>
angular.bootstrap(document.body, ['myApp']);
</script>
</body>
</html>
```
Note that for bootstrapping purposes, the `<html>` element is the same as `document`, so the following
will also throw an error.
```
<html>
...
<script>
angular.bootstrap(document, ['myApp']);
</script>
</html>
```
You can also get this error if you accidentally load AngularJS itself more than once.
```
<html ng-app>
<head>
<script src="angular.js"></script>
...
</head>
<body>
...
<script src="angular.js"></script>
</body>
</html>
```
