AngularJS Question

How to access the $scope variable in browser's console using AngularJS?

I would like to access my

$scope
variable in Chrome's JavaScript console. How do I do that?

I can neither see
$scope
nor the name of my module
myapp
in the console as variables.

Answer

Pick an element in the HTML panel of the developer tools and type this in the console:

angular.element($0).scope()

In WebKit, $0 is a reference to the selected DOM node in the elements tab, so by doing this you get the selected DOM node scope printed out in the console.

You can also target the scope by element ID, like so:

angular.element(document.getElementById('yourElementId')).scope()

Addons/Extensions

There are some very useful Chrome extensions that you might want to check out:

  • Batarang. This has been around for a while.

  • ng-inspector. This is the newest one, and as the name suggests, it allows you to inspect your application's scopes.

Playing with jsFiddle

When working with jsfiddle you can open the fiddle in show mode by adding /show at the end of the URL. When running like this you have access to the angular global. You can try it here:

jQuery Lite

If you load jQuery before AngularJS, angular.element can be passed a jQuery selector. So you could inspect the scope of a controller with

angular.element('[ng-controller=ctrl]').scope()

Of a button

 angular.element('button:eq(1)').scope()

... and so on.

You might actually want to use a global function to make it easier:

window.SC = function(selector){
    return angular.element(selector).scope();
};

Now you could do this

SC('button:eq(10)')
SC('button:eq(10)').row   // -> value of scope.row
